Furnace rolls dry and water cooled:
Thin slab with continuous casting machine enter directly into the soaking roller-hearth furnace after scale cutting and the furnace bottom roller conveys to the hot rolling mill for rolling.
Furnace roller required that products can bear high temperature resistance, pressure resistance, wear resistance in special conditions , according to the different special steel ,our company manufactures roller ring, shaft head, roller.We use various means to ensure the quality of the product in order to meet customers’ requirements.
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.
