&Through nearly half a month's preparation and commissioning, the integrated dosing device of the rolling mill of Longgang company of shaangang has been put into operation in the water transportation system.
Since the implementation of the "upgrade and version 4.0 to build yulonglan" initiative in September 2017, Longgang has been committed to continuous improvement of steel quality and customer satisfaction through process parameter screening, equipment operation status comparison and key media monitoring.
The suspended matter index of production water for rolling line is an important factor affecting the surface finish of steel. The operation of the integrated dosing device can accurately control the amount of medicine added through the metering pump, so as to promote the settlement of suspended matter in water. The suspended matter index of water can be reduced from 260m / L to 30mg / L below, so as to meet the needs of rapid improvement of water quality and steel surface quality. At the same time, it can be large. It plays an important role in realizing efficient, green, clean and environmental protection production by greatly reducing the replacement amount of new water and reducing the consumption of new water.
