silico manganese stands out as one of the most imperative requirements needed for the manufacturing of steel. At JSPL, HC silico manganese, one of the pre-requisites for making graded steel in Steel Melting Shop (SMS), is sourced from the captive Submerged Arc Furnace (SAF) plant at Raigarh, Chhattisgarh.

• COLUMNS:UC 152 mm x 152 mm to UC 356 mm x 368 mm
• LengthUp to 18 meter

Produced as per various Indian & international standards, these sections are superior in terms of strength, efficiency, higher axial and bending load bearing capacities, workability and economy vis-à-vis conventional tapered flange beams. These parallel flange beams and columns enable complex fabrications in high volumes due to inherent functional advantages. When used under bending load, steel savings of up to 10-25% are achieved, as beams of lower sectional weight can be used.

• Size (mm)5.5 – 22.0
• Tolerance (mm)+/- 0.10
• Coil outside diameter1250 mm

The 0.6 MTPA capacity wire rod mill at Patratu is equipped with latest technology from Morgan Construction Company, USA (now known as Siemens). This mill is operational with advanced rolling equipment such as reducing and sizing mill (RSM), high speed shear, pinch rolls and laying heads along with controlled temperature rolling and controlled cooling to meet the processing requirements of various grades of carbon and alloy steel. This results in improved mechanical properties due to finer and more uniform grain size suitable for rapid spheroidised annealing or high-yield strength with optimal scale weight and type.

Direct-reduced iron (DRI), also called sponge iron is produced from direct reduction of iron (in the form of lump, pellets or fines) by a reducing gases produced from natural gas or coal. This reduction takes place in the temperature range 800- 1050 degrees C when reducing gases; mainly Hydrogen and Carbon-monoxide; react with the iron oxides to produce iron. The degree of metallization, defined as the extent of conversion of iron oxide into metallic iron, is 92-96% in a typical DRI process. This high percentage of metallization makes DRI a highly suitable input for steel making. The specific investment and operating costs of DRI plants are low compared to integrated steel plants and are more suitable for many developing countries where supplies of coking coal are limited. This holds true for India where most of the coking coal has to be imported.

The use of clean steel which is free from harmful impurities, inclusions on account of in-house and virgin raw material combined with the state-of-the-art steel refining facilities lends excellent durability.Walking beam type reheating furnace of 200 tonnes hour capacity (Make: ITALIAMPIANTI TENOVA), 5-stand continuous roughing mill with 2 vertical stands and 3 horizontal stands, 10-stand continuous intermediate and finishing mill with 7 universal stands in intermediate train and 3 horizontal stands in finishing train

The production of TMT rebars involve a combination of plastic deformation of steel in austenitic stage followed by quenching and further tempering. The process controls at each critical operation ensure uniform properties in each rebar and provides the TMT rebars with a soft ferrite and pearlite fine grained core, a strong and tough tempered martensite layer imparting it with high ductility as well as strength thus making it ideal for high rises, dams, bridges, individual houses and any critical structures where high yield strength is required without compromising on the elongation properties.The TMT rebars are conforming to the latest BIS-1786: 2008 specifications and are available in Fe 500D, Fe 550D&600 grade in normal, EQR & CRS quality, where Fe 500D grade is highly suitable for seismic prone areas.
