Casting rolls refer to the types of rolls manufactured by direct casting of smelted molten steel or smelted molten iron.

Casting rolls can be divided into two categories: cast steel rolls and cast iron rolls according to their materials; according to their manufacturing methods, they can be divided into two categories: integral casting rolls and composite casting rolls.

  • Which rolls are suitable for integral casting production?

Blooming mills, continuous billet rolling mills, large section steel and rail beam rolling mills, hot-rolled sheet and strip mills, scale breaking and edge rolling machines, section steel universal rolling mills, and small section steel, wire and bar rolling mills Roughing stands and other rolling mills Most of the rolls used are produced by the integral casting method. Such rolls use thicker layers and deeper hole patterns. In addition, the two-high roughing roll of the hot-rolled strip mill is also suitable for integral casting production. The process method of the integral casting roll is relatively simple, and the manufacturing cost is low.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_btn title=”About LMM GROUP” link=”url:https%3A%2F%2Fwww.lmmgroupcn.com%2Fabout-lmm%2F|target:_blank”][vc_column_text css=”.vc_custom_1649296177864{margin-top: 50px !important;}”]friendship Link:
