Ore Crusher Casting

Ore Crusher Casting

The casting is a metal molded object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injecting, inhaling or other casting method, and after cooling, after falling sand, cleaning and then Processing, etc., the resulting object with a certain shape, size and performance. The theoretical metal liquid forming of castings is often called casting, and the proportion of liquid molded parts in machinery and equipment is very large. Here we talk about castings of ore crushers.

The slower the cooling rate of the crusher, the better the diffusion and graphitization of carbon, while the fast cooling prevents graphitization. During casting, the cooling rate is greatly affected by the modeling material, the casting method and the wall thickness of the casting. The metal casting is easy to obtain white mouth, the sand casting is easy to obtain the gray mouth; the thin wall casting is easy to obtain the white mouth, and the crusher is easy to obtain the gray mouth. The thicker the wall, the better the graphitization.

The crusher represents the combined effect of chemical composition and cooling rate on the structure of the cast iron. Casting wall thickness, cooling rate and chemical composition on cast structure The performance of cast iron cast iron is dependent on the properties of the metal matrix and is closely related to the amount and morphology of the graphite. Graphite has a very low mechanical properties compared to the matrix, so the crusher can treat graphite as a hole or crack in the substrate. Thus, the larger the volume occupied by graphite, the lower the performance of the casting. Under the same graphite volume, the properties of cast iron will depend on the morphology and distribution of the graphite. Therefore, the more graphite in the crusher cast iron, the larger the size of the graphite, the more the segmentation effect on the metal matrix, and the worse the performance of the cast iron.

The flake graphite in the gray cast iron of the crusher acts as a crack in the matrix. When the crusher is subjected to tensile load, the crack source is easily formed along the graphite end, so the tensile strength of the crusher gray cast iron is very low. Under compressive stress conditions, cast iron will exhibit a sufficiently high compressive strength, close to the properties of steel. Therefore, the crusher can be considered as the compressive strength and hardness of cast iron during compression.

The use of castings is very extensive, and it has now penetrated into large machinery industries such as construction machinery and equipment. Not only the process flexibility is large, the adaptability is wide, the complicated inner cavity and the shape blank can be manufactured, and the liquid molded parts are low in cost, and the waste machine parts and chips can be directly used, and the overall cost of the equipment is reduced.
