Hard alloy cutting pick

Abstract

The invention discloses a hard alloy cutting pick, which is characterized by being prepared from, by weight percent, 0.5-0.65% of carbon, 0.06-0.12% of titanium, 1.2-1.6% of chrome, 4.2-5.8% of nickel, 0.26-0.32% of manganese, 0.35-0.42% of silicon, 0.01-0.022% of bismuth, 0.025-0.028% of vanadium, 0.016-0.019% of phosphorus, 3.8-3.95% of boron, 0.03-0.035% of scandium, and 0.025-0.028% of cerium;the allowance is iron and unavoidable impurities. The intensity, hardness and wear resistance of the hard alloy cutting pick are significantly improved, the service life is greatly extended, and themining cost is reduced.

Description

technical field

[0001] The invention relates to a metal material, in particular to a cemented carbide pick. Background technique

[0002] The pick is a tool used for breaking rocks and dropping coal, cutting coal rocks, and crushing coal on coal mining devices such as coal mining machines, roadheaders, and coal plows in the coal industry. The pick is usually installed and fixed on the pick seat, and the rotating mechanism of the coal mining device drives the pick to rotate together. The rotating pick directly cuts the coal rock. Export coal. Because the picks will be repeatedly and directly impacted and rubbed by the coal mine in the broken coal mine, the wear is serious, and the service life is often short, so the worn picks need to be replaced frequently, and the rotating mechanism of the coal mining device is usually equipped with many picks. Therefore, it takes too much time to replace the pick every time, which affects the working efficiency of the coal mining device ...
