本厂热处理连续网带式调质炉,主要用于调质SWRCH35K和SCM435钢材质的产品,碳势控制在0.35%,淬火炉的网带最长使用不超个6个月,有时只能用1个月就发生脆断,网带断裂形貌如图1,网带材质为SUS310S不锈钢,一直以来认为是网带材质有问题,后来使用日本进口材质,使用寿命还是没有提高,为此对断裂网带进行了金相分析和相关试验,找到了解决方法,显著延长了网带的使用寿命。
The factory heat treatment of continuous network belt quenching furnace, mainly used for quenching and tempering SWRCH35K and SCM435 steel products, carbon potential control at 0.35%, quenching furnace network with the longest use of no more than 6 months, and sometimes only 1 month brittle fracture, mesh fracture appearance as shown in Figure 1, mesh material made of SUS310S stainless steel, has been considered a problem with the mesh material, and later the use of imported materials in Japan, the service life or not, for fracture Mesh belt metallographic analysis and related tests, to find a solution, significantly extending the life of the mesh belt.
