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] Embodiment 1: with reference to attached figure 1 and 2 . A special super-strong high-chromium crushing wall for a conical sand making machine, which includes a crushing wall assembly. The material of the crushing wall 1 is high-chromium white wear-resistant cast iron, and its chromium content is equal to or greater than 9%, and is 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 broken wall 1 of high chromium white anti-wear cast iron has built-in mesh bars 6 . The mesh bars 6 are strip mesh bars or grid mesh bars.

Embodiment 2

[0013] Embodiment 2: with reference to attached Figure 1-3 . A special super-strong high-chromium crushing wall assembly for a conical sand making machine, which includes a crushing wall and a crushing wall backing plate, and the gap between the high-chromium white wear-resistant cast iron crushing wall 1 and the crushing wall backing plate 3 is filled The layer is a zinc alloy layer 2, and the broken wall 1 of high chromium white wear-resistant cast iron has a built-in mesh bar 6. The mesh bars 6 are strip mesh bars or grid mesh bars. A plurality of pouring grooves 4 for pouring zinc alloy are formed on the mating surface of the high-chromium white wear-resistant cast iron crushing wall 1 and the crushing wall backing plate 3 . The broken wall backing plate 3 is made of high manganese steel. A plurality of pouring grooves 4 for pouring zinc alloy are formed on the matching surface of the crushing wall backing plate 3 and the high chromium white cast iron crushing wall 1 ....

Embodiment 3

[0014] Embodiment 3: On the basis of Embodiments 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 watering grooves 4 for watering zinc alloy are formed on the matching surface of the broken wall backing plate 3 and the moving cone 5 .

Abstract

The invention relates to a superstrong high-chromium breaking wall and an assembly dedicated for a conical sand making machine, which are characterized in that high-chromium wear-resistant white cast iron is used for manufacturing a breaking wall in the conical sand making machine so as to enhance the wear-resistant performance and the non-fragile performance of the breaking wall for several times. The superstrong high-chromium breaking wall comprises a breaking wall assembly, wherein the high-chromium wear-resistant white cast iron breaking wall is made of high-chromium wear-resistant white cast iron of which the chromium content is more than or equal to 9% and less than or equal to 32%, and mesh reinforcements are built in the high-chromium wear-resistant white cast iron breaking wall. The superstrong high-chromium breaking wall has the advantages that: the wear-resistant performance of the breaking wall is greatly enhanced and is about 5 times of that of the traditional high-manganese breaking wall, the service life of the breaking wall is greatly prolonged, and the use cost of users is drastically lowered; in addition, the impact resistance of the high-chromium wear-resistant white cast iron breaking wall is enhanced by the physical structure, the impact force borne by the high-chromium wear-resistant white cast iron breaking wall is effectively slowly released, the defect that the high-chromium wear-resistant white cast iron breaking wall has high possibility of being damaged by impact is overcome, and the manufacturing cost is reduced at the same time.

Description

technical field [0001] The invention relates to a special super-strong high-chromium crushing device for the cone sand making machine, which uses high-chromium white anti-wear cast iron in the production of the crushing wall assembly in the cone sand making machine, and improves the anti-wear performance of the crushing wall several times. The utility model relates to a wall and an assembly, which belong to the field of manufacturing the crushing wall assembly of a cone 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 r...
