Production method of Martensitic Cast Steel of high hardness and excellent Wear Resistance Coatings for Wear by abrasion and impact in Mining Applications, large size Cast Steel grinding and Crushing and obtained
This refers to a Manufacturing method of a Martensitic Cast Steel of high hardness and excellent Wear Resistance under conditions of abrasion and impact for large pieces such as anti-wear Coatings used in Mining operations of grinding and crushing, Guinea Pig In chemical composition, expressed as a percentage by weight, includes 0.35 ~ C ~ 0.60 0.55%, 1.30% si, 0,60 ~ 1.40% Mn, 4.5 ~ 6.50% Cr, 0.0% ~ 0.60 and 0.30 ~ 0.60% Mo, 0.0 ~ 0.70% Cu, 0.010 ~ 0.10%, 0.10% 0,0 0,0 ~ ti, ~ 0.10 ~ 0.050% 0,0% ZR, NB, P less than 0.035%, less than 0.035% s, less than 0.030% n, optionally 0.0005 ~ 0.005% B, optionally 0.015 ~ 0080% Rare Earth, and the stock of Hi Erro. The production method of Cast Steel includes Melting, Casting and Heat Treatment.The merging can be done in Basic Electric Arc Furnace with Refractory or acid or oven, Electric Induction. The Fusion in Electric Arc Furnace as a normal operation includes merger, insufflation of Oxygen, blockade, Refining and deoxidization. Melting in Electric Furnace IND Destruction includes Melting, refining, control of Nitrogen in solution and pickling.Heat Treatment includes Temple in Still air or forced according to the thickness of the parts, followed by a Heat Treatment Tempering.The Cast Steel is described in the present exhibits excellent resistance to impact and abrasion - a balance of the chemical composition in conjunction with additions of microalloys to obtain High hardenability and complete Hardening in large castings, TYP Only up to 14 inches thickPreferably with Brinell hardness around 630 BHN under the conditions of Heat Treatment applied.
