Embodiment Construction
[0023] The present invention will be specifically described below. The invention discloses a VN, TiN powder high chromium cast iron, in which there are powders, the powders are VN with a purity of 99.5% and TiN with a purity of 99.3%, and the powders account for the weight of the high chromium cast iron The percentages are 2-4% VN and 2-4% TiN, the high chromium cast iron also includes 3.1-3.9%C, 18-22%Cr, 0.5-1.0%Si, 0.6-1.6%Mo, 0.6-1.2% Mn, 0.1-0.4%Ni, 0.04-0.09%V, 0.011-0.031%S, 0.018-0.030%P, and the balance is the base material of iron. The average particle size of the powder used is 20-40 nanometers.
[0024] The preparation method of the high chromium cast iron material is: the preparation method comprises the following steps:
[0025] 1) Melting the base material with an intermediate frequency induction furnace at a melting temperature of 1440-1550° C. to obtain the base metal liquid. The electric furnace is a 250 kg intermediate frequency induction furnace;
