Abstract Many types of explosions often occur in industrial settings, and research is being conducted to identify the causes and establish preventive measures. The aim of this study is to investigate slag yards, where metal residues are cooled in the steel industry, often causing steam explosions. The cause of accidents and explosion simulation analyses were used to investigate the sources of steam explosions in a slag yard. The explosion intensity of 4 kg of TNT was measured for the purpose of predicting the intensity of a steam explosion. This was compared with a simulation of explosion damage that occurred in 2017. These results could not be produced from small-scale experiments, and they indicate that damage resulting from actual explosions poses a potential risk to pipes that cannot be directly observed. We conclude that this damage can lead to a domino accident, and this study provides results for estimating the possibility of future damage.

基于现场调查和3D爆炸损伤模拟的渣场蒸汽爆炸实证分析

摘要 工业环境中经常发生多种类型的爆炸，正在开展研究以确定原因并制定预防措施。本研究的目的是调查渣场，在钢铁工业中冷却金属残留物的地方经常会引起蒸汽爆炸。通过事故原因和爆炸模拟分析，对渣场蒸汽爆炸源进行了调查。为了预测蒸汽爆炸的强度，测量了 4 公斤 TNT 的爆炸强度。这与 2017 年发生的爆炸损坏模拟进行了比较。这些结果无法通过小规模实验得出，它们表明实际爆炸造成的损坏对无法直接观察到的管道构成潜在风险。
