我厂二轧分厂薄板车间的1.2米薄板轧机上一直使用铝铁青铜轴瓦,这种轴瓦制造复杂、成本高、原料供应不足,因此常常影响生产。我们热处理小组在装箱渗硫的基础上试制成电焊渗硫钢瓦,使用效果较好,且成本低、强度高、寿命长。把BJ3钢浇铸成的钢瓦(或以前废的钢瓦)在车床上将工作面车至比 Our factory has been using aluminum-iron bronze bushings on the 1.2-meter thin-plate mill of the second rolling mill’s thin-plate workshop. This kind of bearing bush is complicated and costly to produce, and therefore the supply of raw materials is insufficient, so it often affects the production. We heat treatment group in the box on the basis of sulfurized trial trial welding welded steel smelting watts, the use of better, and low cost, high strength, long life. The BJ3 steel cast into the tile (or previously scrap steel tile) in the lathe will face to car than the ratio
