based on the combustion characteristics of oxyhydrogen flame, a new flash-back arrestor faced on oxyhydrogen flame applied for oxyhydrogen welding and cutting equipment is designed.
基于氢氧焰的燃烧特性,设计了一种用于氢氧焊割设备的新型氢氧焰回火防止器。
fumed silica from silicon tetrachloride vapor in an oxyhydrogen flame hydrolysis, compared with natural silica, silica of high purity silica, inert, resistance to ultraviolet light.
application in reality proved that making use of the electrolyzing oxyhydrogen flame for the billet cutting have great economic effect, social utility and spacious prospect.
