Application of Water Pinch Technology in Steel Plant

Water pinch technology is an efficient tool for saving water and reducing wastewater in process industries.Though water pinch technology is relatively mature in theory,and many enterprises such as petrochemical enterprises and chemical enterprises have applied successfully in practical operation,but report in metallurgical field is rare in the world.This paper introduced the principles of water pinch technology and raised the procedures of applying it in Shougang Group.At last,taking a revamping project for water saving as example,this paper put forwards the scheme on optimization of water supply net.Application result showed that the effect of saving water was fairly good.
