Let's learn about measures to reduce and prevent the formation of oxide scale today. For the flame heating furnace, according to the heating environment factors that affect the formation of oxide scale, corresponding measures can be taken in the heating process to achieve the purpose of reducing the formation of oxide scale. The main measures are as follows:
Srednje zaštitno grijanje. Izolirajte površinu gredice od oksidacijskog plina iz peći kako biste spriječili oksidaciju gredice pri zagrijavanju. Mediji koji se koriste uključuju plinovite zaštitne medije (kao što su čisti plin, ukapljeni naftni plin, dušik itd.), tekuće medije (kao što je talina stakla, rastaljena sol, itd.) i čvrste zaštitne medije (kao što su drveni ugljen, stakleni prah, emajl praškasti i metalni premaz Pričekajte).
Let's learn more about the hazards of oxide skin. Oxide scale will cause a large amount of loss of metal materials: The oxide scale generated when metal is heated causes a large amount of loss of metal materials. In general, {{0}}.5 percent to 3.0 percent of the metal is burned out every time the billet is heated. In severe cases, the burn rate can even reach 5 percent
