铝合金或铜合金型材厂普遍使用3Cr2W8V作热挤压模材料。一般情况下,型材厂家都委托外厂沿袭盐浴炉加热进行热处理,所花成本相当高。我们认为这些型材厂家可以利用自身的熔化炉燃烧室进行淬火加热,这些燃烧室往往以焦炭为热源。经我们多次试验,发现焦炭炉在1100℃左右有一个热稳定区,持续时间较长,很适宜3Cr2W8V淬火加热。淬火后的模具型腔无氧化脱碳,而且在工作刃带处有0.10mm左右的增碳层,这有利于 Aluminum or copper alloy profiles commonly used 3Cr2W8V hot extrusion die material. Under normal circumstances, profile manufacturers have entrusted the factory followed the salt bath furnace heat treatment, the cost is quite high. We think these profiles manufacturers can use their melting furnace combustion chamber for quenching and heating, these combustion chambers are often coke heat. After our many tests, found that the coke oven at about 1100 ℃ has a thermal stability zone, a longer duration, it is suitable for 3Cr2W8V quenching and heating. After quenching the mold cavity oxide-free decarburization, but also in the work of the margin of about 0.10mm carbon layer, which is conducive to
