It successfully operates the bar mill supplied to Amreli Steels Ltd., a rebar steel producer based in Karachi, Pakistan. The rolling mill is designed to produce around 400,000 metric tons of reinforcing steel and round bars every year. The new bar mill has tripled the production capacity of Amreli Steels Ltd., which is now in an ideal position to meet the demands of increasing construction activity in Pakistan. The finished products meet national and international standards.
Amreli Steels is the leading producer of rebars in Pakistan, and up to now had an annual production capacity of 200,000 metric tons of rebar. In Pakistan, a large number of infrastructure, residential and commercial construction projects are currently at the planning stage. In order to bridge the demand-side gap of Pakistan´s steel industry, Amreli Steels undertook this expansion project, boosting its production capacity to allow for these developments.
The new bar mill from POMINI Long Rolling Mills has a capacity of 400,000 metric tons per year. It can roll up to 75 tons of steel bar per hour at a top rolling speed of 13 meters per second. The mill processes billets with a square cross-section of 150 x 150 millimeters, a length of 12 meters, and a weight of 2,080 kilograms. The finished products are rebars with diameters ranging from 8 to 40 millimeters. The productivity of the plant is maximized by rolling bars with diameters of between 8 and 10 millimeters in four-slit mode, and diameters between 12 and 14 millimeters in two-slit mode.
POMINI Long Rolling Mills designed the plant and supplied the processing equipment starting from the billet discharging system at the reheating furnace. The rolling line consists of a roughing mill with a VHVHVH arrangement, an HVHVHV intermediate mill, and a finishing mill with an HVHHHH arrangement. Each of these mills is equipped with six fifth-generation Red Ring stands. The scope of supply also included hot cropping and emergency shears, a heat-treatment POMINI Quenching System (PQS) installed downstream of the last stand of the finishing mill, a pinch roll and hot dividing shear in front of the cooling bed. This is followed by a cold dividing shear and machines to count, bundle, weigh and label the bars. POMINI Long Rolling Mills also supplied the guides, lubrication and hydraulic systems, basic automation, motors, drives and an uninterruptible power supply. In addition, POMINI Long Rolling Mills assisted the customer with construction and commissioning work.
