18Hi 6 Tandem Cold Rolling Mill

The world's first internationally competitive stainless steel 18Hi 6 tandem cold rolling mills currently.

20Hi precision reversible cold rolling mill

The company's latest designed twenty-roller precision rolling mill is equipped with imported shape rollers, edge finders, and thickness gauges (with cross-section scanning). It has online edge detection capabilities and adopts the leading fully automatic shape closed-loop control system at home and abroad. And transmission control, with a maximum production speed of 600m/min and a minimum rolling thickness of 0.02mm. This mill is equipped with a dual motor drive design that can simultaneously meet the high-speed production of hard and medium-thick specifications and the stable and high-precision tension of soft and ultra-thin specifications to control production.

Facility Optimization

Except for entire mill line,we are also professional in equipment revamping and system optimization to reuse the existing parts, to maximum extent, based on actual working condition and in adoption of most advanced technology, so as to largely save equipment investment and production cost. Revamping 6-high mill into 18-high mill (typical reference) 1.Before revamping,the work roll diameters ranged from 200 to 240mm which were so large that it caused small rolling reduction,too many passes and low efficiency.The minimum thickness could only reach 0.6mm for strip of width 1250mm; 2.After revamping,the roll diameters of 18-high mill is reduced by 120 to 140mm,the minimum thickness reaches 0.25mm with width 1250mm, so the rolling efficiency is increasing significantly by bigger reduction of each pass; 3.Most worn facilities were revamped by reusing the existing parts, e.g. support roll, to lower production cost with higher efficiency.

Stainless Steel Annealing & Pickling Line

Stainless steel cold-rolled annealing & pickling process is mainly to eliminate work hardening by recrystallizing the cold-rolled stainless steel after annealing.

Grinding Line for Stainless Steel

Grinding line for stainless steel is mainly used for rough or intermediate surfacegrinding of hot-rolled or cold-rolled coils. Both the top and bottom surface can bground by setting the direction of uncoiling.
