本文叙述了硅铁在添加了碱金属,如钙、钡、镁等活性添加剂后,在保管、加工和运输过程中容易产生爆炸的原因。在某一铸造车间当破碎含钡3.62%的65硅铁时发生了爆炸。经分析认为,此系合金粉末和水相互作用生成了氢气和乙炔的缘故。合金中有碱金属存在,容易生成氢;在有钡存在时,合金中的硫化物易分解出乙炔。在1m~3容积的球磨(?)中,如果含有40克水,或者加入湿度0.5%的100公斤的产品,所含水分足够引起爆炸。
This paper describes the reasons why ferrosilicon easily explodes during storage, processing and transportation after the addition of alkali metals such as calcium, barium, magnesium and other active additives. An explosion occurred in a foundry when crushing 65% ferrosilicon containing 3.62% barium. The analysis shows that the alloy powder and water interact to generate hydrogen and acetylene. Alkali metal alloys exist, easy to generate hydrogen; in the presence of barium, the sulfide in the alloy is easy to decompose acetylene. In a 1 to 3 volume ball mill (?), Containing 40 grams of water or adding 100 kg of moisture at 0.5% contains enough moisture to cause an explosion.
