退火是将钢材或各种金属机械零件加热到适当温度，保温一段时间，然后缓慢冷却，可以获得接近平衡状态组织的热处理工艺。其目的是为了细化组织、降低硬度、改善机械切削加工性能及去除内应力。在机械制造行业，退火通常作为工件制造加工过程中的预备热处理工序。

　　强对流电加热罩式光亮退火蓝化炉主要适用于黄铜带、青铜带、异型铜带、紫铜带、各类精密铜管、造币材料、精密带钢、复合带材、软磁和硬磁合金、铜合金线材、标准件材料、不锈钢带等几十种材料。单座钟罩炉装料直径3.2M，装料高度达4M，装炉量80T。考虑到一些小型金属加工企业无燃气来源、无煤炭来源，所以该炉采用电阻带的加热方式，与燃气罩式退火炉比较起来运行成本相对稍高，生产周期相对长一点。但是，其设备配置简单，运行可靠，维修方便，退火工艺各阶段温度可设定，能满足各种金属的退火需要。

　　该电加热罩式退火炉采用单套控制系统独立控制双炉座加热退火炉，炉体本身使用了新型轻质节能材料，结构设计合理，保温效果好，当电阻带温度达到1000℃时，加热罩外壳只是环境温度加上40℃。料室保护气采用氮氢气，使得被退火材料在高温退火状态下无氧化、无脱碳。采用抽真空系统节约大量的保护气体和电源能耗。控制系统采用单套西门子S7-200系列PLC全自动控制两套加热炉的升温、保温、冷却过程，采用灵敏度高的热电偶分别采集炉体外罩和内罩的温度，根据工艺设定的升温、保温时的温度值PID调节加热器的工作状态和加热频率，保证保温温度的恒定，并配有8寸的触摸屏，可以生动形象地对各个炉座的升温、保温、冷却过程实行了*的控制与管理，为用户生产合格的产品提供可靠的保障。
