The invention discloses a manufacturing process for a rolled-steel heating furnace slide block. The manufacturing process comprises the following steps of: manufacturing a bottom assembly and a top assembly of the slide block; connecting the bottom assembly to the top assembly through a heat-resisting bolt, and connecting the bottom assembly and the top assembly to a water-cooling pipe of a heating furnace after shot-blasting, wherein the bottom assembly is made of a heat-resistant alloy, and the top assembly is made of composite ceramic; and the heat-resistant alloy consists of the following components in parts by weight: 0.1-0.3 part of C, 0.2-1 part of Si, 1-3 parts of Mn, 25-32 parts of Cr, 36-38 parts of Co, 14-18 parts of Ni, 2-5 parts of W, 1-3 parts of MO, 0.02-0.2 part of Ce and 20-30 parts of Fe. The slide block manufactured by the manufacturing process is good in heat resistance and pressure resistance. 本发明公开种轧钢加热炉滑块的制备工艺，包括：制备所述滑块的底部组件和顶部组件；将所述底部组件和所述顶部组件通过耐热螺栓连接后经喷丸处理后与所述加热炉的水冷管连接；所述底部组件材料为耐热合金，所
