Abstract

The invention discloses a composite material capable of improving abrasion resistance and heat resistance of a steel casting and a production technology. The composite material includes siliceous sand, bauxite, kyanite, rutile and zircon sand, magnesia and olivine. The granularity of the siliceous sand, the granularity of the bauxite, the granularity of the kyanite, the granularity of the rutile and zircon sand, the granularity of the magnesia and the granularity of the olivine all range from 0.212mm to 10mm. According to the composite material capable of improving the abrasion resistance andheat resistance of the steel casting and the production technology, abrasion resistant particles are added into cast steel, and the abrasion resistance of the casting is improved; when the composite material is used on the surface of a product, the tenacity of the whole product can also be improved; and no heat treatment operation is required in the course of working. Compared with a traditional composite material and a production technology, the composite material capable of improving the abrasion resistance and heat resistance of the steel casting and the production technology have the advantages that production cost is lower and mass popularization can be facilitated. Production cycle can be shortened to a great extent, and no residual sand can be bonded on the surface of the casting easily. Due to the fact that molten iron makes contact with the sand, cooling speed is high, white ironing is facilitated, and the hardness of the product is further improved. Meanwhile, the using amount of the molten iron is decreased and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of steel castings, in particular to a composite material and a production process which can improve the wear resistance and heat resistance of steel castings. Background technique [0002] Steel castings are parts made of cast steel, similar in performance to cast iron, but stronger than cast iron. Steel castings are prone to defects such as porosity defects and inaccurate angle positioning during the casting process. In the long-term use, the phenomenon of casing breakage may occur. In the process of steel castings and high manganese steel castings, due to improper process operations , the model cracks, the model collapses, the paint is not painted in place, the paint falls off, and the high-temperature molten iron enters the gap of the surrounding molding sand; or the molding sand is rushed into the mold during the molten iron casting process and gathers together, etc. The above quality conditions occur. ...
