Problems solved by technology

Generally, the appearance and size of the macro-composite research parts of the macro-ceramic reinforced steel matrix are relatively large, and it is difficult to put the mold into the heating furnace.
If an effective infiltration process cannot be carried out, it is difficult to obtain high-quality, stable and consistent performance of ceramic reinforced steel matrix composite parts

example 1

[0031] Example 1. Casting infiltration of vertical mill roller sleeve inserts

[0032] The roller sleeve insert is a typical ceramic particle reinforced metal matrix composite wear-resistant material, which is made into a roller sleeve after secondary casting, and is used as a wear-resistant part of a vertical mill. At present, there are many domestic research and development units, but due to quality reasons, especially the combination between ceramic particles and high-chromium cast iron is not tight enough, that is, the compound is not good enough, and the quality is unstable, so far, it has not been applied in the market.

[0033] Use the implementation steps of the present invention as follows:

[0034] Molding: Molding with water glass quartz sand, coating the surface of the sand mold with magnesia paint, and then preheating the sand mold at 300°C to 500°C.

[0035] Make the prefabricated body of the ceramic reinforcement and preheat it to 500°C to 600°C, or put it in t...

[0041] Example 2 Cast infiltration of vertical mill disc liner

[0042] Molding: Molding with water glass quartz sand, coating the surface of the sand mold with magnesia paint, and then preheating the sand mold at 300°C to 500°C.

[0043] Make the prefabricated body of the ceramic reinforcement and preheat it to 500°C to 600°C, or put it in the sand mold at a set position and preheat it together with the mold.

[0044] Fit the mold, and move the composite part of the sand mold (casting mold) to the side of the heating coil, and put the side containing the prefabricated block close to the surface of the coil, and the surface of the coil matches the curved surface of the composite part in the sand mold. like image 3 .

[0045] Pour high-chromium cast iron molten metal into the sand mold, and at the same time energize the electromagnetic induction coil to raise the temperature of the molten metal by 100-200°C within 60 to 90 seconds to reach the required infiltration temperatu...

Abstract

The invention provides a method for manufacturing a ceramic reinforcement metal matrix composite material using preform cast-infiltration through inductance coil transverse flux heating. The inventionprovides a method of open-type inductance coil heating, and the method is used for a casting infiltration process for manufacturing the ceramic reinforcement metal matrix composite material. A to-be-heated body is not wound by a coil, a casting mold with a ceramic preform can be placed in an electromagnetic inductance coil field to be cast, heated and subjected to heat preservation, the casting infiltration process is completed, and a sand mold can be used as the casting mold. The method is suitable for not only the casting infiltration of medium and large sized nonferrous alloy based ceramicreinforcement composite parts, but also the casting infiltration process of high temperature metal liquids of large, medium and small parts, such as a steel-iron alloy based ceramic reinforcement composite material.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a method for casting and infiltration of metal-based composite materials with ceramic reinforcements. Background technique [0002] In the production of ceramic reinforced metal matrix composites, the prefabricated body infiltration process is one of the effective means. For microscopic ceramic reinforced composites, especially non-ferrous metal matrix composites with low melting point, such as aluminum, copper, etc. The casting and infiltration process of ceramic reinforced metal matrix composites is to place the prefabricated body in the mold, and the mold and the matrix metal are placed in a heating furnace to heat and melt the matrix metal, keep it warm, and perform infiltration. Due to the small space in the heating furnace, this method cannot produce medium and large ceramic reinforcement non-ferrous alloy matrix composite materials. [0003] For ceramic rein...
