Operational problems at coke battery 6 of Rourkela Steel Plant in India are considered. The structure of coke battery 6 of PVR type (useful capacity of the coke ovens 41.6 m3) is described; it is characterized by bottom supply of the heating gas and hybrid heating. Removing the scale buildup from the inclined section of the heating channels improves the thermal and hydraulic conditions, extends coke-battery life, and eliminates nonuniform heating of the coke cake. © 2016, Allerton Press, Inc.

Rourkela Steel Plant, India, has commissioned Hot Strip Mill (HSM), which produces 1.6Mt of hot rolled coils a year by rolling 101,000 slabs each of weight 15.5t at a rolling rate of around 275t/h. An automatic tail end cutting system for cutting the tail of the rolled slab after reduction in the roughing stands, to transfer bar, is designed, developed, and implemented successfully in the HSM. The system consists of two Fiber Optic Hot Metal Detectors (FOHMD), pulse tachometer, and a programmable controller (PLC). The hardware components of the system include fiber optic hot metal detectors, pulse tachometer, and PLC. The software component consists of a program which counts the pulses and calculates the linear speed based on the diameter of the pinch roll monitored. The project augments the tail end cutting system in the crop shear for transfer bars to achieve a reduction in crop ends, reduction in coil chute up and resultant mill delays, and elimination of fish tail cutting at the coil finishing area thereby increase coil yield.

The C, Mn and Si impart high strength to steels through solid solution strengthening. On hardening and tempering, these elements further increase the strength substantially by exploiting hardenability potentials. With this point in view, a microalloyed C-Mn-Si steel was designed to have elements in the range of C:0.24-0.28, Mn:1.30-1.50, Si:1.30-1.50, Cr.0.10-0.20, Ni:0.20-0.40, Mo:0.15-0.25, P:0.015max, S:0.010max and H:2ppm max. Aiming at this range of chemistry, steel was made in an electric arc furnace, refined in VAD and continuous cast to 170mm x 1160 mm slabs. Prior to hot rolling of the slabs, hot deformation and dilatation studies were carried out in a Gleeble-3500C system for simulating hot rolling and heat treatment schedules. Employing the designed parameters, the slabs were hot rolled to 5 mm x 1135 mm x 4600 mm plates, which were subsequently hardened and tempered to obtain hardness levels >460 BHN, YS >1300 MPa, UTS >1500 MPa, elongation >8% and reduction in area >25% in the material. The plates contained >95% martensite in the microstructure and observed to have adequately smooth surfaces free from defects such as holes, roll marks, scabs and rolled-in scale, etc. © (2013) Trans Tech Publications, Switzerland.

Rourkela Steel Plant (RSP) is a major steel plant integrated under Steel Authority of India Limited (SAIL). RSP produced 2.17 Mt of crude steel during the year 2011-2012 and is under expansion to enhance its capacity to 4.2 Mt. There are two steel making shops (SMS-I and II), but the major production of RSP comes from two 150 t converters at SMS-II. This shop presently blows 32-36 heats per day by means of 7 steel ladles in operation, with a fleet size of 18 steel ladles. These steel ladles are lined with an MgO-C working lining and facilitate the transfer of liquid steel from the basic oxygen furnace (BOF) to continuous casting machines (CCM). Secondary metallurgical treatment is conducted in a ladle arc furnace (LF) to fine tune the composition and argon (Ar) bubbling is applied for homogenization. The steel ladle lining life plays a major role affecting the quality of the steel produced since lower ladle life means higher inclusion in steel and the cost of production. This paper will elaborate on the performance of ladle life, including lining patterns and operational aspects in SMS-II at RSP. © 2013 Expert Fachmedien GmbH.

Rourkela Steel Plant (RSP) has undergone massive modernization to increase production from the existing level of 2.18 Mt to 4.2 Mt crude steel after commissioning of one additional 4060 m3 blast furnace and a third converter of 150 t capacity in Steel Melting Shop-II (SMS-II). The increased volume of quality steel production will largely depend on shop productivity with higher converter availability along with a lower down time for maintenance. The design and refractory quality of the tap hole sleeve for the converter plays an important role in the production of liquid steel and availability of the converter. At RSP, MgO-C quality zonal lining material is manufactured at the inhouse brick plant (LDBP) while the tap hole sleeve for the converter is procured from various reputed refractory manufacturers. The life of the sleeve varies between 58 heats and 100 heats with an average of around 70 heats. The frequent change of tap hole sleeves not only affects converter lining life due to thermal spalling but also decreases availability of the converter. Improved dense quality tap hole sleeves with less material segregation leading to uniform density, chemical composition and strength across the entire tap hole length were procured and tried in converter A of SMS-II. These tap hole sleeves were manufactured in small pieces, pre-assembled to the required size and delivered as single entities of varying denominations. The service life of these tap hole sleeves reached an average level of 93 heats with a peak of 130 heats and the major portion of heats fell within 5-7 min tap duration which helped in less slag carryover and suggestive of reduced consumption of deoxidants.
