用电渣熔炼法来熔炼废锋钢,不需要复杂的设备和装置,生产效率高,质量好,成本经济合算,是利用回炉锋钢(一股的短车刀,废铣刀,废铰刀等)来制造刀具的一项有效措施。电渣熔炼时,强大的电流通过金属电极,将渣池加热到2000℃以上,电极金属熔化并以细滴状落下而沉淀,最后得到质量很好的金属锭。我厂利用这种方法熔炼废锋钢来制造刀具,结果完全令人满意。电源是用-34-y型交流电焊机。电极是废高速钢用18-8型不銹钢焊条焊接起来的。电焊机的一极接金
The use of electroslag melting smelting waste front steel, does not require complicated equipment and devices, high production efficiency, good quality, cost-effective cost-effective, is the use of back front steel (a short tool, milling cutter, reamer Etc.) to make a tool an effective measure. When electroslag melting, a strong current through the metal electrode, the slag pool heated to above 2000 ℃, the electrode metal melts and drops down to precipitate, and finally get a good quality ingot. I plant the use of this method smelting waste front steel to make knives, the result is completely satisfactory. The power supply is -34-y AC welder. The electrodes are scrapped HSS welded with 18-8 stainless steel electrodes. One of the welding machine gold
