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.

Acid Regeneration Plant

1.Large amount of waste acid generated from mixed-acid pickling process will impose large stress on water recycling if it is eliminated directly due to its high acid concentration and metal ions,which also wastes large amount of resource and result in high production cost. 2.The system recycles acid-waste via calcination and rinse absorbing.The metal- salt contained is converted in redox reaction under high temperature and reused. 3.Main technical parameters: Processing capacity:2500～6000l/h HF recycle rate:>95% HNO3 recycle rate:70%～75% Nearly zero elimination of waste water. Nearly 100%recycle of metal ions.

Disposing System

1.Mixed-acid pickling process generates large amount of exhaust gas containing hazardous pollutants like HF and NOx. 2.This disposing system eliminates HF and NOx from exhaust gas through rinsing, absorbing and denitration to ensure its emission under standards. 3.The pollutants in exhaust gas can be processed to satisfy following standard through this system: HF<5mg/m3 NOX<200mg/m3
