罩式退火炉(These modernization projects include: No.3 Sendzimir mill; No.2 skinpass mill; automatic shape control on No.2 Sendzimir mill； CNC roll grinders; No.3 slitting and packaging line； cut to length line upgrade; No.9 and 10 bell annealing furnaces; upgrade of cooling and electrolytic pickling sections of No.1 annealing and pickling line. 这些现代化项目包括 3 号森吉米尔式轧机、2号平整轧机、2号森吉米尔式轧机的形状自动控制装置、 CNC 轧辊磨床、3 号纵剪/打包作业线、定尺切割生产线升级改造、9号和 10 号罩式退火炉和 1 号退火和酸洗生产线的冷却及电解酸洗段改造。)
球化退火(The heat-treatment processes of steel parts include hardening, annealing, normalizing, spheroidizing annealing, stress-relief annealing and case hardening. 钢质零部件的热处理法包括：淬火、退火、正火、球化退火、去应力退火和表面硬化等。)
去应力退火(【技】在略低于再结晶温度下加热钢件，用于消除内应力的热处理。: Stress-relief annealing is the simplest heat treatment and is accomplished merely by heating metal to 649 - 732°C followed by air or furnace cooling. 去应力退火是一种最简单的热处理方式，只要将金属加热到649 -732°C, 随后空冷或炉冷，去应力退火即告完成。)
