Remote centralized control project-Silicon steel
The world's first silicon steel remote centralized control project,the overall planning and core production line are jointly planned and completed by WQY and Hongwang group.(Hunan Hongwang Group Remote centralized control silicon steel 20Hi rolling mill. 1.The world's first 18Hi six-stand all-series silicon steel special rolling mill. 2.The world's first 18Hi six-stand all-series silicon steel special rolling mill. 3.Hunan Honqwang Group Remote centralized control APL mill (oriented +non-oriented dual purpose).
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.
Multi-Roll Tension Leveling Line
The shape of soft materials after annealing or hard materials after degreasing can be improved by certain elongation, bending and straightening in this unit.
20-High Splitblock Rolling Mill
“Zero Crown”Design for Integrally-casting Mill Housing ·Strong mill modulus, and rolling force radiated and applied on each section of housing; ·Big pass reduction with small work roll diameter; ·Providing axial and radial roll shape adjustment, roller diameter compensation, pass line adjustment etc.; ·Hydraulic screw down system and hydraulic AGC system for which the processed materials can obtain excellent flatness and high gauge accuracy.
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
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.
