Problems solved by technology

However, the strength of the slag collection layer is not enough, the adhesion to the molten slag is not strong enough, and it is easy to break when removing slag; the raw perlite ore will cause splashing when it bursts on the surface of molten iron, and some unexpanded particles are easy to enter the cavity from the gate and cause slag inclusion Defects, etc.
With perlite raw ore as the main component, some deficiencies of per

Abstract

The invention discloses a casting slag remover. A casting composite slag remover consists of pre-treated expanded perlite and a composite additive, wherein the composite additive comprises the following components of, in parts by weight, 2-40 parts of quartz sand powder, 0.1-10 parts of iron ore tailing powder, 5-40 parts of magnesia powder and 35-60 parts of sodium bentonite powder, and the weight ratio of the pre-treated expanded perlite to the composite additive is 80-95: 5-20. The casting composite slag remover can be used for correspondingly selecting and adjusting the use ratio accordingto different situations such as casting alloy types, casting processes, casting sizes and the like. The casting composite slag remover has the characteristics of strong adhesion to molten slag, highslag collecting layer strength, difficult crushing during slagging off, high slag removal efficiency and the like. The casting composite slag remover can also be used as a nonferrous alloy casting slag remover.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a casting composite slag remover, in particular to a composite slag remover used in the pouring process in the casting production process. Background technique [0002] The main function of the slag remover is to aggregate and bond the molten slag on the surface of molten iron. It is a product that provides convenience for the slag removal process. The effect of generating new slag. The slag remover is an important auxiliary material in the foundry industry. The performance is directly related to the cleanliness of the molten iron and affects the quality of the casting. [0003] At present, the slag removal agents used in the domestic foundry industry include straw ash, fly ash, quartz sand, clay powder, etc., but mainly perlite ore is directly used as a slag removal agent after crushing and screening. This is the main deslagging agent product in my country as a substitute fo...
