国内外对于碳素弹簧钢丝、制绳钢丝热处理都用连续炉生产。就其加热能源而言,有电、油、煤气和煤。钢丝的冷却方式有铅浴、盐浴、空冷、水冷和最近发展的流动粒子炉等。国内常用的热处理种类有两大类:(一)等温淬火(多用于成品钢丝),(二)正火(多用于半成品钢丝)。不论哪一类,对钢丝加热都需使铁索体(过共析钢为渗碳体)溶入奥氏体中去。一般线温都在900℃左右。加热时间的确定一般以(45秒～1分钟)/mm来计算。对某一座炉是否确当,就以是否能达到所要求的性能和组织为原则。随着能源问题的提
At home and abroad for the carbon spring wire, wire rope heat treatment are used in continuous furnace production. In terms of heating energy, electricity, oil, gas and coal. The cooling of steel wire lead bath, salt bath, air cooling, water cooling and the recent development of mobile particle furnace. There are two types of heat treatment commonly used in China: (A) isothermal quenching (mostly used in finished steel), (B) normalizing (used for semi-finished steel wire). In either case, the heating of the wire requires that the ferrite body (the eutectoid steel be a cementite) be dissolved into the austenite. The average line temperature is about 900 ℃. The determination of heating time is usually (45 seconds to 1 minute) / mm to calculate. The correctness of a furnace is based on the principle of meeting the required performance and organization. With the mention of energy issues
