Siemens to supply bar rolling line for minimill in India

27.10.2014
  • New plant will produce 320,000 metric tons of rebars and special bar quality (SBQ) steels per annum for the Indian and international market
  • Rolling mill will also be able to run in multi-slit mode

SLR Metaliks Ltd., an Indian pig-iron producer, has awarded Siemens Metals Technologies an order to supply a state-of-the-art bar rolling mill for its new steel plant near Hospet. The rolling mill will be designed for an annual production of 320,000 metric tons of rebars and special bar quality (SBQ) grades, primarily for the automotive industry. Bars with smaller diameters will be rolled in multi-slit mode. The new steel plant in Hospet is a value-addition project within the expansion plan of SLR Metaliks Ltd. The bars will be produced to serve both national and international markets. The plant is scheduled to be brought into operation in the first half of 2016.

Siemens will supply the complete process equipment for the new bar rolling mill, including the billet infeed with a hot charging option, the descaling, and the handling of the finished bars. The actual rolling line will consist of a roughing mill and an intermediate mill, each with six Red Ring stands in an HV arrangement, and a finishing mill with six Red Ring stands in an HVC arrangement. This will be followed downstream by a three-stand sizing mill with CGA stands in an HVH arrangement. An inline system will be used for thermo-mechanically rolling the SBQ bars, as well as for quenching and tempering the rebars. The quality of the rolled bars will be controlled by measuring inline the dimensions and profiles with non-contact, laser-based Orbis measuring systems while the mill is running.

A hot dividing and crop shear will be installed between the rolling mill and the cooling bed. Downstream of the cooling bed, another dividing shear will cut the rolled bars to length. This will be followed by automatic bundling, wire-tying and weighing machines. The maximum bundle weight will be five metric tons. The scope of delivery also includes the rolling guides and the fluid systems. Siemens will also supply the low-voltage transformers, motors, drives, mechatronic packages and measuring instruments, as well as the basic L1 automation, including the operator consoles, and the HMI system. Siemens is responsible for the design of the equipment supplied, the entire process planning of the bar rolling mill, and for the customer training. It will also assist the customer with the construction, start-up and commissioning of the plant.

The bar rolling mill will be fed with six-meter billets of carbon and quality steels with a square cross-section of 130 x 130 or 160 x 160 millimeters, and process them to produce rebars with diameters ranging from 8 to 32 millimeters, and SBQ rounds with diameters from 16 to 63 millimeters. The operators will also have the option of producing bars with square and hexagonal cross-sections.
