By discussing the relationship between blast velocity and raceway length, the concept of reasonable blast velocity was put forward, further more, the theoretical foundation and influence factors of reasonable blast velocity were also analyzed in detail. What's more, the various phenomena of blast furnace with different blast velocities and the effective methods of adjusting the blast velocity were also clearly shown. Reasonable blast velocity that is not a definite number but a reasonable controlling range should be changed according to the change of blast furnace production conditions. So that looking for the reasonable blast velocity needs enough time to attempt and explore. Practice has proved that the active hearth and the long-term stable production of blast furnace could be realized only under the condition of reasonable blast velocity.

Different driving decisions will cause different processes of phase transition in traffic flow. To reveal the inner mechanism, this paper built a new cellular automaton (CA) model, based on the driving decision (DD). In the DD model, a driver's decision is divided into three stages: decision-making, action, and result. The acceleration is taken as a decision variable and three core factors, i.e. distance between adjacent vehicles, their own velocity, and the preceding vehicle's velocity, are considered. Simulation results show that the DD model can simulate the synchronized flow effectively and describe the phase transition in traffic flow well. Further analyses illustrate that various density will cause the phase transition and the random probability will impact the process. Compared with the traditional NaSch model, the DD model considered the preceding vehicle's velocity, the deceleration limitation, and a safe distance, so it can depict closer to the driver preferences on pursuing safety, stability and fuel-saving and has strong theoretical innovation for future studies. © 2011 Chinese Physica Al Society and IOP Publishing Ltd.

The increase of traffic flow in cities causes traffic congestion and accidents as well as air pollution. Traffic problems have attracted the interest of many researchers from the perspective of theory and engineering. In order to provide a simple and practical method for measuring the exhaust emission and assessing the effect of pollution control, a model is based on the relationship between traffic flow and vehicle exhaust emission under a certain level of road capacity constraints. In the proposed model, the hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (N O x) are considered as the indexes of total exhaust emission, and the speed is used as an intermediate variable. To verify the rationality and practicality of the model, a case study for Beijing, China, is provided in which the effects of taxi fare regulation and the specific vehicle emission reduction policy are analyzed. © 2013 Han Xue et al.

Fatigue crack growth behaviors of cold-rolled dual phase steels with different microstructures were investigated at room temperature. The ferrite-martensite dual-phase microstructure was obtained by intercritical annealing. Fatigue crack growth (FCG) behaviors were described by both the Paris model and a new exponential model; fatigue fractography and surface morphology near the fracture were arrested by scanning electron microscopy (SEM); the relationship between macroscopic and microcosmic FCG rate was analyzed quantificationally. The results showed that both the models can be used to describe the fatigue crack growth rate of the samples rather well; fatigue striations and secondary cracks were observed in the fracture surface at stable expanding region (II), while the fracture at rapid expanding region (III) combined dimple and quasi-cleavage morphology; the roughness of fracture surface and the degree of secondary cracking increased with an increase in martensite content, leading to a higher threshold value. Moreover, the changes of microcosmic FCG rate were smoother than that of the macroscopic FCG rate. © 2014 Elsevier B.V.

The stringer shaped B type non-metallic inclusions in linepipe steel plates deteriorates the properties of low temperature toughness, hydrogen induced crack, etc. At present the formation mechanism and controlling method of B type inclusions in mass production are rarely reported. In this paper, the characteristics, origin, and controlling method of stringer shaped B type non-metallic inclusions were studied for linepipe steel. The stringer shaped B type non-metallic inclusions in API X80 linepipe steel plates, produced through "BOF-LF-RH-Ca treatment" steelmaking route, were mainly of CaO-Al 2O3 system with lower melting temperatures, which formed because the presence of: (i) small sized liquid inclusions of CaO-Al 2O3 system in liquid steel after the secondary refining and Ca treatment. These small inclusions could aggregate to larger ones of 10-20 μm in continuous casting and be deformed into stringer shaped inclusions in steel plates during rolling. (ii) The large sized low melting temperature CaO-Al2O3 inclusions, in Ca treatment, their surface layers could be modified into high melting temperature CaO, CaS, or CaO-CaS system, but the centers were still of CaO-Al2O3 system. During rolling, these inclusions could also be elongated to stringer typed ones because of their soft CaO-Al2O3 centers. A new strategy for control of B type inclusions in linepipe steel plates was adopted. The key of the control was shifted from removing low melting temperature inclusions of CaO-Al2O3 system after Ca treatment to removing as much as possible inclusions especially large sized inclusions before the Ca treatment. With the new strategy, amount of inclusions after RH refining was remarkably decreased and the efficiency of Ca treatment significantly improved. The inclusions found in steel plates were all of high melting temperature CaO-CaS system and the severities of B-type inclusions have been lowered from "≤2.0" to "0"(ASTM E45 standard). The characteristics, origin, and controlling method of stringer shaped B type non-metallic inclusions in pipeline steel are studied, their composition are mainly of CaO-Al 2O3 system with lower melting temperatures. A new strategy for control of B type inclusions in linepipe steel plates is adopted, than the inclusions in steel plates were all of high melting temperature CaO-CaS system and the severities of B-type inclusions have been lowered from "≤2.0" to "0." © 2014 WILEY-VCH Verlag GmbH & Co.

The purpose of this study was to evaluate microstructural and mechanical change of DP780 steel after tungsten inert gas (TIG) welding and the influence of notch locations on the fatigue crack growth (FCG) behavior. The tempering of martensite in the sub-critical heat affected zone (HAZ) resulted in a lower hardness (~. 220. HV) compared to the base material (~ 270. HV), failure was found to originate in the soft HAZ during tensile test. The fusion zone (FZ) consisted of martensite and some acicular ferrite. The joint showed a superior tensile strength with a joint efficiency of 94.6%. The crack growth path of HAZ gradually deviated towards BM due to the asymmetrical plastic zone at the crack tip. The FCG rate of the crack transverse to the weld was fluctuant. The Paris model can describe the FCG rate of homogeneous material rather well, but it cannot precisely represent the FCG rate of heterogeneous material. The fatigue fracture surface showed that the stable expanding region was mainly characterized by typical fatigue striations in conjunction with secondary cracks; the rapid expanding region contained quasi-cleavage morphology and dimples. However, ductile fracture mechanism predominated with an increasing stress intensity factor range (δ. K). The final unstable failure fractograph was subtotal dimples. © 2015 Elsevier B.V.

The mechanical properties of DP780 dual phase steel were measured by quasi-static and high-speed tensile tests at strain rates between 0.001 and 1000 s−1 at room temperature. The deformation and fracture mechanisms were analyzed by observation of the tensile fracture and microstructure near the fracture. Dynamic factor and feret ratio quantitative methods were applied to study the effect of strain rate on the microstructure and properties of DP780 steel. The constitutive relation was described by a modified Johnson-Cook and Zerilli-Armstrong model. The results showed that the strain rate sensitivity of yield strength is bigger than that of ultimate tensile strength; as strain rate increased, the formation of microcracks and voids at the ferrite/martensite interface can be alleviated; the strain rate effect is unevenly distributed in the plastic deformation region. Moreover, both models can effectively describe the experimental results, while the modified Zerilli-Armstrong model is more accurate because the strain-hardening rate of this model is independent of strain rate. © 2015, ASM International.

Investigations were made both in laboratorial and industrial scales on formation of non-metallic inclusions with relatively lower melting temperatures to improve the fatigue property of the special steels which contained extra low oxygen. It was found in laboratory studies that steel/slag reaction time largely affected non-metallic inclusions in steel. With the slag/steel reaction time increasing from 30 to 90 min, inclusions of MgO-Al 2O 3 spinel were gradually changed into CaO-MgO-Al 2O 3 system inclusions which were surrounded by lower melting temperature softer CaO-Al 2O 3 surface layers. By using high basicity and as much as 41 mass% Al 2O 3 refining slag, the ratio of the lower melting temperature CaO-MgO-Al 2O 3 system inclusions was remarkably increased to above 80%. In the industrial experiments, it was found that the inclusions changed in the order of "Al 2O 3→MgO-Al 2O 3 system→CaO-MgO-Al 2O 3 system" in the secondary refining, and the change from MgO-Al 2O 3 system to CaO-MgO-Al 2O 3 system took place from the outside to the inside. The diffusion of CaO and MgO inside the layer of CaO-MgO-Al 2O 3 was considered as the controlling step of the inclusion transfer. Through LF and RH refining, most inclusions could be transferred to lower melting temperature CaO-Al 2O 3 and CaO-MgO-Al 2O 3 system inclusions. © 2012 Science China Press and Springer-Verlag Berlin Heidelberg.
