coated furnace rolls by Qingdao Hexin Machinery Co.,Ltd.
This is the technology coated furnace rolls .The cooling water flow from one side of the roll along the radial flow from the other side, it makes water cooling roller surface cool, we can use the strip and surface of the coated furnace rollers to contact for heat exchange, so as to we can achieve the purpose of cooling steel strip.The cooling speed of strip is proportional to the two aspects, one is contracting time of the strip and the coated furnace roller surface , the second is flow rate of the cooling water , one of the biggest impact is the former.
After the size cut, the thin slabs are conveyed into furnace directly after that are conveyed by hearth rolls to the hot roll mills.
special operating conditions demands the products with high temperature resistant, to meet the operating conditions, we make the roll collars, spindle noses and roll barrels by different types of special steel and different kinds of process method to ensure the products quality.
