我国煤炭机械化程度正在逐步提高,采煤、掘进、运输、提升、通风(压风)、排水、选矿等环节配套设备多,重量大,面广。但60～80%的零件易于早期磨损失效,造成停机,影响生产,这是当前亟待解决的问题。氧一乙炔焰合金粉末喷涂技术,是一项既经济、见效快、性能可靠、适应面又广的新工艺。采用这种技术能提高工件寿命几倍至几十倍,可为国家节约大量资金和贵重金属。我厂从1983年引进氧一乙炔焰合金粉末
The degree of coal mechanization in our country is gradually improving. Coal mining, roadheading, transportation, upgrading, ventilation (air pressure), drainage, mineral processing and other sectors have many supporting equipment. However, 60 to 80% of the parts are prone to early wear and tear failure, resulting in downtime, affecting the production, which is the immediate problem to be solved. Oxygen-acetylene flame alloy powder coating technology, is not only an economical, quick, reliable, wide adaptation of the new technology. The use of this technology can increase the life of the workpiece several times to several times, for the country to save a lot of money and precious metals. Our factory imported oxy-acetylene flame alloy powder from 1983
