阀片是空气压缩机上的重要易损另件,消耗量很大。我厂年产配件阀片为30～40万件,最高年产达50多万件。阀片不仅消耗量大,而且技术要求高。为达到阀片的技术要求,目前各兄弟厂普遍采用30CrMnSi 钢制造,并在盐炉中加热淬火,以防止表面氧化脱碳。但在盐炉中加热淬火,不仅生产率低(RYD-45盐炉,每炉只能装700件,一小时淬一炉),电能消耗量大315度/5000件,辅助材料消耗多,而且淬火后需卸去夹具进行洗盐,然后重新上夹具进行回火,
Valve is the air compressor on the important wearing parts, consumption is very large. I plant annual output valve parts for the 30 to 400,000, with a maximum annual output of more than 50 million. Valve is not only consumed, but also high technical requirements. In order to achieve the technical requirements of the valve, the current Brother plant commonly used 30CrMnSi steel manufacturing, and quenching in the salt furnace heating to prevent the surface of the oxidation decarbonization. But in the salt furnace heating quenching, not only low productivity (RYD-45 salt furnace, each furnace can only hold 700 pieces, one hour quenching a furnace), energy consumption of 315 degrees / 5000 pieces, auxiliary material consumption, and quenching After removing the fixture for salt washing, and then re-fixture on the tempering,
