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
Technical field
The present invention relates to metallurgical technology field, the heat preserving agent under red heat or fired state in particularly a kind of field of metallurgy.
Background technology
In the prior art,,, prevent that temperature is too high because a large amount of heating of high temperature needs insulation at metallurgy industry, but the heat preserving agent of prior art or insulation material, owing to be passive heat-insulation and heat-preservation all, the insulation degree is limited, has limited use, heat insulation effect is bad.
Summary of the invention
The invention provides the self-heating type thermal insulation covering agent of better heat preservation.
To achieve these goals, the invention provides following technical scheme:
A kind of self-heating type thermal insulation covering agent, it comprises according to mass percent: the dedusting ash 70-80% that the electric arc furnace smelting high titanium slag is produced, silica flour 14-22%, rust red 2-8% and aluminium powder 1-4%.
Wherein, preferred, described self-heating type thermal insulation covering agent according to mass percent, comprising: dedusting ash 75%, silica flour 18%, rust red 5% and aluminium powder 2% that described electric arc furnace smelting high titanium slag is produced.
By implementing above technical scheme, the present invention has following technique effect, the dedusting ash that this self-heating type thermal insulation covering agent is produced with the electric arc furnace smelting high titanium slag is that primary raw material is mixed with heat preserving agent, thereby can ignite by high-temperature medium and emit a large amount of heats, to reach heat insulation effect, belong to self-heating type thermal insulation, better heat preservation.
The specific embodiment
Technical scheme is for a better understanding of the present invention described embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the invention provides a kind of self-heating type thermal insulation covering agent, according to mass percent, comprising: the dedusting ash 70-80% that the electric arc furnace smelting high titanium slag is produced, silica flour 14-22%, rust red 2-8% and aluminium powder 1-4%.
Embodiment one: described self-heating type thermal insulation covering agent according to mass percent, comprising: dedusting ash 75%, silica flour 18%, rust red 5% and aluminium powder 2% that described electric arc furnace smelting high titanium slag is produced.Become behind the dedusting ash impurity screening that the electric arc furnace smelting high titanium slag is produced earlier dust-removing powder, with the silica flour previous status add this dust-removing powder, again aluminium powder and in addition a small amount of silica flour are stirred mixes after adding, when mentioned component stirs, rust red is evenly added.
Embodiment two: described self-heating type thermal insulation covering agent according to mass percent, comprising: dedusting ash 76%, silica flour 18%, rust red 4% and aluminium powder 2% that described electric arc furnace smelting high titanium slag is produced.Become behind the dedusting ash impurity screening that the electric arc furnace smelting high titanium slag is produced earlier dust-removing powder, with the silica flour previous status add this dust-removing powder, again aluminium powder and in addition a small amount of silica flour are stirred mixes after adding, when mentioned component stirs, rust red is evenly added.
Embodiment three: described self-heating type thermal insulation covering agent according to mass percent, comprising: dedusting ash 80%, silica flour 14%, rust red 5% and aluminium powder 1% that described electric arc furnace smelting high titanium slag is produced.Become behind the dedusting ash impurity screening that the electric arc furnace smelting high titanium slag is produced earlier dust-removing powder, with the silica flour previous status add this dust-removing powder, again aluminium powder and in addition a small amount of silica flour are stirred mixes after adding, when mentioned component stirs, rust red is evenly added.
The foregoing description provide thermal-insulating covering agent should or conduct: need the thermal-insulating covering agent under red heat and the fired state in the insulation of the surface heat preservation of the various liquid metals of metallurgy industry, the various liquid metals of casting industry, the casting industry in the heat preserving agent of the slow cooling agent of heat preservation, the heat treatment industry of casting rising head and the other industry.During use, this thermal-insulating covering agent is also covered as heat-insulation layer at the even uniformly dispersing of the dielectric surface that will be incubated, this insulation layer thickness is greater than 10mm, and the residue cooling back after this thermal-insulating covering agent uses comes off naturally.
More than a kind of self-heating type thermal insulation covering agent that the embodiment of the invention provided is described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
