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

Embodiment 1

[0012] Example 1: refer to the attached figure 1 and 2 . A special super high-chromium crushing wall for a cone-type sand making machine, which includes a crushing wall assembly, the crushing wall 1 is made of high-chromium white anti-wear cast iron, and its chromium content is equal to or greater than 9%, equal to or less than 32 %, namely 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, and including two The decimal point between the integers, the high-chromium white anti-wear cast iron crushing wall 1 has built-in mesh bars 6 . The mesh reinforcement 6 is a strip mesh reinforcement or a mesh mesh reinforcement.

Embodiment 2

[0013] Example 2: refer to the attached Figure 1-3 . A special super high-chromium crushing wall assembly for a cone-type sand making machine, which includes a crushing wall and a crushing wall backing plate, and the gap between the high-chromium white anti-wear cast iron crushing wall 1 and the crushing wall backing plate 3 is filled The layer is a zinc alloy layer 2, and the high-chromium white wear-resistant cast iron crushing wall 1 has built-in mesh bars 6. The mesh reinforcement 6 is a strip mesh reinforcement or a mesh mesh reinforcement. A plurality of pouring grooves 4 for pouring zinc alloy are opened on the mating surface of the high-chromium white-mouth anti-wear cast iron crushing wall 1 and the crushing wall backing plate 3 . The crushing wall backing plate 3 is made of high manganese steel. A plurality of pouring grooves 4 for pouring zinc alloy are opened on the mating surface of the crushing wall backing plate 3 and the high-chromium white anti-wear cast i...

Embodiment 3

[0014] Example 3: On the basis of Examples 1 and 2, the gap filling layer between the broken wall backing plate 3 and the moving cone 5 is a zinc alloy layer 2 . A plurality of pouring grooves 4 for pouring zinc alloy are opened on the mating surface of the broken wall backing plate 3 and the moving cone 5 .

Abstract

The invention relates to a super-strong high-chromium crushing machine dedicated to the cone sand making machine, which uses high-chromium white anti-wear cast iron to make the crushing wall of the cone sand making machine, and improves the anti-wear performance and brittleness resistance of the crushing wall several times. Wall and assembly, which includes the broken wall assembly, the high chromium white wear-resistant cast iron broken wall material is high chromium white wear-resistant cast iron, its chromium content is greater than or equal to 9%, equal to or less than 32%, high chromium The white wear-resistant cast iron crushing wall is built with mesh reinforcement. 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 problem of the high-chromium white wear-resistant cast iron crushing wall. Shock breakage defects while reducing manufacturing costs.

Description

technical field [0001] The invention relates to a special super-strong high-chromium crusher for the cone-type sand making machine, which uses high-chromium white anti-wear cast iron for the manufacture of the crushing wall assembly in the cone-type sand making machine, and improves the anti-wear performance of the crushing wall by several times. The utility model relates to a wall and an assembly, which belongs to the field of manufacturing the crushing wall assembly of a cone-type sand making machine. Background technique [0002] The 3c-21cr high cast iron currently in the theoretical research stage, combined with various hammers used in the crusher, combine the 3c-21Cr high chromium cast iron with various carbon steels (including 45# cast steel, 35# cast steel, 30# cast steel) Steel), high manganese steel, low alloy steel and other components of the bimetallic composite hammer. The "dual-liquid" bimetallic composite casting process and the heat treatment process of bime...
