一、前言到目前为止,模具的淬火加热都使用盐浴炉。虽然盐浴加热本身有不少优点,如加热强度大,能达到较高的加热温度,以满足大多数高合金工模具钢淬火加热温度的需要。在良好脱氧的情况下,氧化脱碳倾向小。另外随时可从炉中取出及装入工件,生产的灵活性较大。其不足之处是劳动条件差,污染生产环境,淬火后有盐残留在工件表面,需要清洗,这就增加了生产工序,降低了生产效率。对于那些带有盲孔、深孔、细小孔、或型腔复杂的精
First, the preface So far, the mold quenching heating using salt bath furnace. Although salt bath heating itself has many advantages, such as heating intensity, can reach higher heating temperature, in order to meet the most high alloy die steel quenching temperature needs. In the case of good deoxidation, the tendency of oxidation decarburization is small. At any time from the furnace can be removed and loaded into the workpiece, the production of greater flexibility. The disadvantage is the poor working conditions, pollution of the production environment, salt residue after quenching the workpiece surface, the need for cleaning, which increases the production process and reduce production efficiency. For those with blind holes, deep holes, small holes, or cavities complex essence
