Global Steel Processing Market Information Report by Steel Type (Alloy Steel, and Carbon Steel), by Application (Construction, Energy, Automotive, Consumer Goods and others), and by Region - Global Forecast to 2022Pune, India - April 25, 2017 /MarketersMedia/ — Market Research Future published a half cooked research report on Global Steel Processing market. The Steel Processing market is expected to grow over the CAGR of around 2% during the period 2016 to 2022 Market Highlights: Steel processing is generally classified into two types that is primary and secondary steel making. Primary steel processing converts liquid iron from a blast furnace or steel scrap into steel. This can be done using melting the scrap steel in electric arc furnace. Secondary steel processing includes the refining of crude steel and different operation. The factor which are responsible for the growth of steel processing market are growing demand for the processed steel in the developing countries due to infrastructure development and growing industrialization. Various other factors which drive the growth are increasing population and increasing urbanization. Asia-Pacific region is expected to witness the highest growth during the forecast period because leading steel processing industries are mainly focusing on developing countries. Also demand for steel in the region is expected to grow in coming time due to low production and cheap labor. Many European countries have setup their plants in Asia-Pacific region because of low cost of production. Asia-Pacific will be the largest market for steel processing because the companies in Asia-Pacific are willing to take capital intensive projects, with the help of technical experts.

This work mainly presented two aspects, inverse problem model technique that allowed detailed description of heat transfer behaviors in the mould from simulations of coupled measured temperature. Additionally, shell growth rate defined for discussing irregular shell growth was presented for wide and thick continuous casting slab. As a result, the inverse problem model provided good agreement on prediction of mould temperatures. Furthermore, the model's transient approach could show the non-uniform characteristics of heat flux and shell thickness. The non-uniformity of heat transfer was significantly prominent on outside radius face more than that of inside radius face, and the non-uniformity of shell thickness distribution on narrow face is smaller than that of wide face. It was also able to analyze behavior of initial solidified shell within the mould through the shell growth rate. Shell growth rate reached the maximum in the region of 100-200 mm below meniscus, as well as local heat flux. Effect of casting speed on the non-uniformity of heat transfer and shell growth rate was also discussed. Although complex in nature, these models likely became part of optimization and control of continuous casting process. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

In this present paper, a two-dimensional (2D) transient finite-difference model was developed. By solving appropriate inverse problem from the measured temperatures by thermocouples buried at various locations in the mold wall, the unknown heat flux between the strand and mold was identified. The temperature calculated in present model agreed well with actual plant data, and the results gave obvious non-uniform characteristics of heat flux and shell thickness, which could better reflect the real casting conditions of strand. The influence of casting speed on average heat flux and shell thickness at the mold outlet was calculated as follows: increase of casting speed caused increase of average heat flux and decrease of solidified shell thickness at the mold outlet. Furthermore, the relationship between average longitudinal heat flux and shell thickness of mold outlet was discussed, and it resulted in that the heat transfer from the strand to the mold remarkably determined the thickness and non-uniformity of the solidified shell. © 2012 Elsevier B.V.

Effect of increasing heat input on microstructure evolution and impact toughness of coarse grained heat affected zone (CGHAZ) in high Nb X-100 multi-phase pipeline steel was investigated by means of Gleeble simulator, optical microscope (OM), scanning electron microscope (SEM) and electron backscattering diffraction (EBSD). Charpy impact test confirmed the optimum toughness of CGHAZ was achieved at heat input of 20. kJ/cm, equivalent to the excellent toughness of the base plate. Observations performed by OM, SEM and EBSD show that the microstructure of CGHAZ varies dramatically with heat input without a noticeable changing in prior austenite grain size, and the optimum toughness achieved at the heat input of 20. kJ/cm is related to the cumulative contribution of its well-refined martensite/austenite (M/A) constituent and the highest density of high angle boundaries. Analysis on crystallography shows that high angle boundaries are mainly the boundaries between the products from different Bain groups produced from the fcc to bcc coherent transformation within prior austenite grain, and the density of high angle boundary is controlled by the configuration of Bain groups within the crystallographic packet in each austenite grain. With the ideal configuration, the density of high angle boundary can be optimized to be beneficial to keep high toughness in CGHAZ, together with well-refined M/A constituent. This indicates that in addition to M/A refinement, the characteristic in crystallography of the crystallographic packet (the configuration of Bain groups within it) is related to the mechanical properties of CGHAZ and should be controlled to be optimum. © 2012.

Deep drawing properties of hot rolled gas cylinder steel was investigated by using HP295 steel in terms of microstructure, texture, yield ratio, plastic strain ratio (r-value) and plastic anisotropy (Δ. r). The grains in the hot strip were largely equiaxed, and the texture was weak, containing α- and γ-fibre. Reheating temperature, finish rolling temperature and cooling rate after rolling influenced the ferrite-pearlite band formation significantly, and the yield ratio increased steeply with decreasing coiling temperature below 630 °C. The anisotropy is relatively high due to retained severe ferrite-pearlite band. A mechanism of the band formation due to manganese segregation is elaborated and confirmed validly, from which the measures to avoid the band formation are worked out. Rolling parameters have been optimized by the measures, and industrial production of the gas cylinder steel has been made possible with much improved r-and Δ. r-values, while meeting other specifications. © 2012 Central Iron and Steel Research Institute.

Five ferrite/bainite (F/B) dual-phase steels with the chemistry of low carbon, high manganese and high niobium, and different volume fractions of bainite (15%-98%) were produced by control rolling+relaxing+ACC processing. With the help of the modified Crussard-Jaoul (C-J) analysis, the effects of soft phase (ferrite) content and its grain size on the work-hardening behavior of the steels and the cooperative deformation relationship between softer phase and harder phase were studied, which was validated by EBSD analysis. The results illustrate that a reasonable proportion of F/B can be helpful to improve initial work-hardening (a high R t1.5/R t0.5), reduce the yield ratio, and maintain a high uniform elongation. It is known that the cooperative deformation of ferrite and bainite is the main mechanism for improving the stress ratio and the uniform elongation of the F/B dual-phase steels. © Rright.
