1. Brief

Cold rolling project, with importation of internationally advanced technology and key equipment (such as four-stand six-high rolling mill from Mitsubishi-Hitachi, Japan and electric equipment from Hitachi, Japan), is aimed at building a pickling-tandom cold rolling mill production line (PL-TCM) with full hydrogen hood type annealing furnace and corresponding coil leveling machine and finishing shearing unit, etc. The production line was put into operation in February 28, 2004. Production capacity for the first stage of the project reaches 152.8X104 tons.

Production capacity for the project is 152.8X104 tons of cold rolled sheet /coil per year, among which cold rolled merchant sheet /coil accounts for.82.8 X104 tons and full-hard cold rolled coil 70 X104 tons as raw material for galvanizing.
