Thermal insulation deslagging agent

Abstract

The invention provides a thermal insulation deslagging agent, wherein pearlite is selected with low expansion coefficient through tests to serve as heat preservation deslagging agent, which achieves the same effect as the SLAX heat preservation deslagging agent by low cost. The invention can be applied before the casting step in the casting industry.

Description

1. Technical field: [0001] The invention relates to the technical field of metal casting, in particular to a thermal insulation and slag removal agent. 2. Background technology: [0002] In the traditional metal casting industry, traditional plant ash has been used for heat preservation of molten metal in the ladle before casting. Plant ash has disadvantages such as flammability, difficulty in storage, and dust pollution to the environment. Chinese patent 92105897.7 has introduced a kind of synthetic slag collecting agent, thinks that when the perlite content reaches more than 80%, problems such as excessive viscosity will occur, sticking bag easily, hanging slag, turning bag not clean. At present, a SLAX thermal insulation and slag removal agent used in the domestic foundry industry is a kind of mineral slag remover. It is generally believed that the effect is good, but its price is as high as nearly 4,000 yuan / ton, which will undoubtedly increase the cost of foundry enterp...

Problems solved by technology

[0002] In the traditional metal casting industry, traditional plant ash has been used for heat preservation of molten metal in the ladle before casting. Plant ash has disadvantages such as flammability, difficulty in storage, and dust pollution to the environment.

Chinese patent 92105897.7 introduces a synthetic slag collecting agent, and it is believed that when the perlite content reaches more than 80%, there will be problems such as excessive viscosity, easy sticking, hanging slag, and unclean bag turning.

At present, a SLAX thermal insulation and slag removal agent used in the domestic foundry industry is a mineral slag remover. It is generally believed that the effect is good, but its price is as high as nearly 4,000 yuan / ton, which will undoubtedly increase the cost of foundry companies.
