The first set of rolling mill was composed of six main lines which are imported from the U.S.A. which include a push and pull type pickle line with the annual production capacity of the 300000 metric tons, a 4-high reversing cold rolling mill with the annual production capacity of the 150000 metric tons, a non-reversing temper mill with the annual production capacity of the 250000 metric tons, batch-type annealing furnaces (36 bases) with the annual production capacity of the 1600000 metric tons, and a slitter line with the annual production capacity of the 150000 metric tons.
One 4-high reversing cold rolling mill was imported from Italian MINO Company with the annual production capacity of the 250000 metric tons of cold rolled steel strip .The standards of product are 0.2~2.0mm thickness, 620~1270mm width and 9~22 metric ton per coil. The rolling mill was equipped of AGC thickness auto control system and AFC flatness control system. The combination of all the equipments can enter the advanced line of the international markets.
One set of high accuracy recoiling line with annual production capacity of 160000 metric tons. Its electric system 、 automatic system and strentch technics are imported Italian EDM Company. The hardware and software of this line have international advanced level. The flatness of the strip less than 4i after strentched.
One set of electrolytic degrease pickling line with annual production capacity of 200000 metric tons. Through degrease disposing, 98% of greasy impurity and 95% of iron impurity attached on the surface of steel strip can be removed. |
