实践证明:按50%氯化铵、45%氯化钡、6%糖浆此例配方的脱氧剂,不但能有效的克服了因化学热处理而产生的表面脱碳,而且使生产费用大大节省。现介绍如下:一、脱氧原理氯化铵加热后分解成氨及氯化氢:NH_4Cl→NH_3↑+HCl↑其中的氯化氢与碳酸钡起化学反应;而部分的氨 Practice has proved that: 50% ammonium chloride, 45% barium chloride, 6% syrup of this formula deoxidizer, not only can effectively overcome the chemical heat treatment surface decarburization, but also greatly reduce production costs. Now introduced as follows: First, the principle of deoxygenation Ammonia and hydrogen chloride decomposition after heating ammonium chloride: NH_4Cl → NH_3 ↑ + HCl ↑ where the hydrogen chloride and barium carbonate chemical reaction; and part of the ammonia
