Blanking: the roll body of the continuous casting roll is made of seamless steel pipe, the shaft is made of 45 round steel, and the end plate is made of Q235 steel plate. 8mm machining allowance is reserved for cutting according to the size of the drawing.

Turning: turning the joint surface of the matching parts of roller body, end plate and shaft, and machining according to the matching accuracy of H9 / F9.

Weld the stiffeners, shafts at both ends and other parts in the combined roller body, pay attention to correct the coaxiality between the shafts at both ends and the inner sleeve, and only weld the inner end plate on the shaft.

Install the assembled and welded complete inner sleeve into the roll body, and assemble and weld the mating junction between the inner end plate and the roll body.

Install the outer end plate on the shafts at both ends, and weld the junction between the outer end plate and the joint surface of the shaft and roll body. Anneal the welded roller blank to eliminate the internal stress.

One end of the steel roller shaft shall be turned flat, and the standard center hole shall be drilled.
