二、不锈钢钢析及钢卷用的炉子生产不锈钢钢板时基本上采用两种热处理方式: (一)在带淬火液的火焰炉内加热,然后钢板或钢带表面进行酸洗处理; (二)不锈钢在保护气体内光亮退火。镍铬不锈钢的热处理规定要加热到高温(1100°—1150°),因之建造高产量的直通式连续加热炉还要保证这种钢材均匀加热在技术上是很困难的。因为耐热钢的辊子内即使含有大量的镍,在1100°—1150°时也没有足够的强度,建造可靠的使钢带或钢板在炉内移动的设备就发生了困难。耐热的炉内带式运输机或是个数很少的水冷支撑辊子可以认为是直通式炉(用来连续热处理不锈钢钢带)的相当可靠的支承装置。在炉子短的时候支持辊
Second, the stainless steel and steel coils used in the production of stainless steel plate basically uses two kinds of heat treatment: (A) with a quenching fluid in the flame furnace heating, and then pickling plate or strip surface treatment; (B) Stainless steel in the protective gas bright annealing. The heat treatment of nickel-chromium stainless steel requires heating to a high temperature (1100 ° -1150 °), which is technically very difficult due to the construction of high-throughput continuous-flow continuous furnaces. Because heat-resistant steels, even with large amounts of nickel in the rollers, do not have sufficient strength at 1,100 ° -1150 °, difficulties have arisen in building reliable equipment for moving the steel strip or plate in the furnace. Heat-resistant in-furnace belt conveyors or a small number of water-cooled backup rollers can be considered as a fairly reliable support for straight-through furnaces for continuous heat treatment of stainless steel strip. Support the roller short in the furnace
