High chromium crushing wall and assembly for cone sand making machine

Abstract

The invention relates to a special high-chromium crushing wall and assembly for a cone sand making machine, which uses high-chromium white anti-wear cast iron for the production of the crushing wall of the cone sand making machine, which improves the anti-wear performance of the crushing wall several times. It includes a crushing wall assembly, and the material of the crushing wall is high-chromium white wear-resistant cast iron, and its chromium content is equal to or greater than 9% and equal to or less than 32%. Advantages: First, the wear resistance of the broken wall is greatly improved, and its wear resistance is about 5 times that of the current high manganese steel broken wall. Not only the service life is greatly extended, but the user's use cost is also greatly reduced; The structure improves the impact resistance of the high-chromium white wear-resistant cast iron crushing wall, effectively slows down the impact force on the high-chromium white wear-resistant cast iron crushing wall, and solves the high-chromium white wear-resistant cast iron crushing wall. Defects that are vulnerable to impact.

Description

technical field [0001] The invention relates to a high-chromium crushing wall and a special high-chromium crushing wall for a cone-type sand-making machine, which uses high-chromium white anti-wear cast iron in the production of the crushing wall assembly in the cone-type sand making machine, so that the anti-wear performance of the crushing wall is improved several times. The assembly belongs to the manufacturing field of the crushing wall assembly of the cone type sand making machine. Background technique [0002] The 3c-21cr high cast iron, which is currently in the theoretical research stage, is combined with various hammer heads for crushers to combine 3c-21cr high-chromium cast iron with various carbon steels (including 45# cast steel, 35# cast steel, and 30# cast iron) Steel), high manganese steel, low alloy steel and other bimetal composite hammer. The "two-liquid" bimetal composite casting process and the heat treatment process of bimetal castings used in the resea...

Problems solved by technology

However, this method cannot be used in the manufacture of the crushing wall and the crushing wall assembly in the cone sand making machine. There is no way to slow down the force of the crushing wall when it is impacted during the sand making process, which will easily cause damage to the crushing wall and shorten the service life. short
