Through many years engaged in the production of heat-resistant steel castings, has accumulated a wealth of experience, but also have their own views on some of the ideas for how to increase the service life of heat-resistant steel products, we can share with you.

Heat-resistant steel castings production when the need to use a variety of equipment and accessories, tempering must be carried out before it is operating, mainly in order to eliminate the internal stress of the casting process. Placing the workpiece while ensuring uniform, work can not be stacked in one local position, it would lead to uneven heat oven plate during the heating process, eventually leading to the furnace plate deformation and cracking problems.
When using slings, baskets, the best choice of material for ZG40Gr25Ni20 electrode, because such electrode materials have good creep resistance in the quenching process, not cause serious deformation of the spreader and the baskets and cracking help extend its life.
