含球墨成份的冷铸轧辊是国营江都农机修造厂的主要产品之一,早在1989年该厂就购进了一个容量为1.5t的密封加镁铁水包。在使用中粘附在内壁衬胆上的残余铁水渣越积越厚,形成一个形似内壁搪泥的罐体。若不及时清除,容铁水量将愈益减少。罐体的抬肩处(即最大直径处)又大于包壳的上口,残渣罐体清不出去,影响到加镁包的继续使用,阻碍了球墨轧辊的生产。
The chilled roll with nodular ink is one of the main products of State-owned Jiangdu Agricultural Machinery Repair Factory. As early as 1989, the factory purchased a sealed ferrous-magnesium package with a capacity of 1.5t. In use, the residual molten iron slag adhered to the inner wall of the liner is thicker and thicker, forming a tank body which is shaped like an inner wall of the liner. If you do not promptly removed, Rong capacity of the water will be reduced. The shoulder of the tank (ie, the maximum diameter) is larger than the upper mouth of the shell, and the residual tank can not be cleared out, affecting the continuous use of the magnesium bag and hindering the production of the nodular roll.
