The influence of three heating variants, during hardening on the properties of national manufactured ИЧX2H4 white cast iron were evaluated at laboratory scale in order to predict the feasibility of using it on the manufacturing of mining equipments for abrasion and impact conditions. Cast samples, with controlled chemical composition and further annealed, were used for evaluating three heating variants with air quenching. The chemical composition of cast samples was in correspondence with the composition established by the standard GOST 5632-72. After air quenched, samples were annealed and characterized using optical microscope and hardness testing. It is concluded that in the three evaluated of heating variants, the required properties for manufacturing parts from equipments that undergo severe abrasion and impact loads were obtained; such as crashing and grinding mining equipments. |
