我厂用风铲清理铸钢件,铲头消耗量很大,有时甚至出现来不及制造铲头而造成清砂停产。后来,我们分析了铲头服役条件和失效形式,改进了热处理工艺,使铲头寿命提高5～7倍。现介绍如下。图1所示为铲头零件图及技术要求。铲头有长1000毫米和800毫米两种,都是用φ22毫米热轧T 8钢棒料车尾部、锻刃部后经热处理制成的。 I plant with a wind shovel clean steel castings, shovel head consumption is very large, and sometimes even too late to produce shovel head caused by sand production. Later, we analyzed the shovel head service conditions and failure forms, improved heat treatment process, shovel head life increased by 5 to 7 times. Now introduced as follows. Figure 1 shows the shovel parts drawings and technical requirements. Shovel head has a length of 1000 mm and 800 mm are two, are φ22 mm hot T 8 bar stock car tail, forging after heat treatment made.
