阿尔哥马钢厂的油田用钢管热处理线,由奥氏体化炉、淬火装置、回火炉以及输送辊道、冷库和成品料架组成。钢管在奥氏体化炉内加热到1500—1700°F后,根据产品性能要求进行正火或淬火处理。淬火一般是通过设在奥氏体化炉出口端的一系列喷水环进行的。需正火时,通过淬火装置(无水淬火),把管水倾卸在1号冷床上空冷。然后在回火炉中以
Algoma steel mill oilfield steel heat treatment line, the austenitizing furnace, quenching equipment, tempering furnace and the conveyor roller, cold storage and finished product rack composition. After the tube is heated to 1500-1700 ° F in an austenitizing furnace, the tube is normalized or quenched according to the product’s performance requirements. Quenching is generally done through a series of water jets located at the exit end of the austenitizing furnace. To be normalized, quench the device (anhydrous quenching), the water dump on the No. 1 cold bed air-cooled. Then in the tempering furnace to
