Self-heating type thermal insulation covering agent

Abstract

The invention provides a self-heating type thermal insulation covering agent, which comprises the following components in mass percentage: 70 to 80 percent of dust which is generated in the smelting of high titanium slag in an electric arc furnace, 14 to 22 percent of quartz powder, 2 to 8 percent of rust red and 1 to 4 percent of aluminum powder. The self-heating type insulating covering agent can release a great amount of heat after the agent is ignited by a high-temperature medium, so the insulating effect is achieved; and the agent belongs to the self-heating type insulation, and thus, the insulating effect is better.

Description

A self-heating thermal insulation covering agent technical field The invention relates to the technical field of metallurgy, in particular to an insulating agent in a red-hot or burning state in the metallurgical field. Background technique In the prior art, in the metallurgical industry, due to the high temperature and large amount of heat, heat preservation is required to prevent the temperature from being too high, but the heat preservation agent or heat preservation material in the prior art is passive heat insulation and heat preservation, and the heat preservation degree is limited, which limits the use. The insulation effect is not good. Contents of the invention The invention provides a self-heating thermal insulation covering agent with better thermal insulation effect. In order to achieve the above object, the present invention provides the following technical solutions: A self-heating thermal insulation covering agent, which comprises: 70-80% of dust remo...
