Excellent type of Steel strip pickling line
Push-pull & continuous 600,000TPY
Beijing JJRS Technology Development Co., Ltd. registered in national high tech park-Beijing Economic and Technological Development Zone, is high-tech enterprise specialized in the complete set of metallurgical equipments, intensive processing of steel strip and metal surface coating engineering project, with the integration of mechanism, optics, electric and hydraulic pressure.
1.Push-pull pickling adopts advanced shallow turbuleimmernt pickling process, with short pickling time and high pickling efficiency. Push-pull pickling can be divided into six sections, each section has its own outer heating and pickling system, through adjusting the temperature of every pickling sections to achieve the best pickling effect.
2.Continuous pickling adopts turbulent shallow pickling process with extinct advantages. The liquid height inside the acid tank is just 150mm, the inner and outer cover of the acid tanks, all can reduce the evaporation and improve the turbulence speed of the acid liquid.
3.Continuous pickling line has three acid tanks, each of them has separated outer heating system and acid recycled system. Through adjusting the temperature, concentration and the turbulence speed of every acid tank to achieve the best acid effect.
4.Using five-stage counter follow cascade rinse system, only need few rinsing water. Though controlling the accuracy of the conductivity in the last rinsing section to ensure the rinse quality of the strip surface.
5.Continuous pickling line has set 800t rolled skin pass mill to improve the defects of the strip shape and the quality of the strip surface, as well as eliminate part of the yield platform, and improve the product competitiveness.
6. Continuous pickling adopt reliable technical, stable running double head rotate tower side trimmer, the open degree of the shear blade, overlap amount, side seam can be adjusted automatically.
