以往的碱性发兰工艺存在着耗能大、效率低、成本高、污染环境等缺陷,在经济效益和劳动条件上都不理想。本文介绍的蒸气发兰工艺,不但可提高工件质量,而且省去很多工序,降低了生产成本,大大提高了工作效率。1.蒸气处理的基本原理当温度为500～570℃通入水蒸气时,工作表面就会生成致密的Fe_3O_4薄膜,其作用机理是水蒸气与热铁接触而分解出活性氧原子,然后活性氧原子与铁反应,生成Fe_3O_4核心,核心继续在金属表面上
In the past, there were some defects such as large energy consumption, low efficiency, high cost and pollution of the environment, which were not satisfactory in terms of economic benefits and working conditions. This article describes the steam hair blue process, not only can improve the quality of the workpiece, and eliminating a lot of processes, reducing production costs and greatly improve work efficiency. 1. The basic principles of steam treatment When the temperature of 500 ~ 570 ℃ access to water vapor, the working surface will generate dense Fe_3O_4 film, the mechanism of action is steam and hot iron contact and decomposition of reactive oxygen atoms, and then reactive oxygen atoms Reaction with iron to generate Fe_3O_4 core, the core continues on the metal surface
