Abstract
The invention discloses a heat preservation agent for a tundish. The heat preservation agent for the tundish is obtained through mixed processing of, by weight, 5%-8% of calcium bicarbonate powder, 14%-29% of sodium bicarbonate powder, 1%-2% of metallic rhenium powder, 1% of zirconium carbonate powder, 5%-16% of niter, 25%-35% of buttonwood saw dust powder, 15%-30% of plant ash, 9%-17% of metallic iron powder and 5%-8% of calcium carbide powder. The heat preservation agent can generate heat, and the heat preservation effect of the heat preservation agent can be improved easily; in addition, the condensation speed of metal liquid of a casting riser can be decreased easily, and the capacity of the heat preservation agent to absorb impurities contained in the metal liquid of the heat preservation agent is improved.
Description
Technical field
The present invention relates to a kind of tundish heat preserving agent, particularly relate to and a kind ofly carry out being incubated heat preserving agent used to molten metal for metal industry casting field.
Background technology
In prior art, in casting field in casting ladle molten metal casting before and casting cycle in all must be incubated.Heat preserving mode continues to use traditional plant ash always, but plant ash have inflammable, have pollution to environment; Patent publication No. is slag-trapping covering agent disclosed in CN1032959A, although have insulation and collection slag function, because perlite content is too high, easy satchel, often causes the damage of watering ladle-lining.Acidity, neutral heat preserving agent that the insulation materials such as current domestic usual use charring rice husk, perlite make, heat insulation effect is poor, and heat preserving agent self does not have heating function, can not compensate the reduction of temperature in casting cycle.
Summary of the invention
Instant invention overcomes the problems referred to above that prior art exists, its object is to propose the agent of a kind of tundish heat preserving agent, heat preserving agent heat insulation effect is desirable simultaneously to have heating function, and collection slag performance is strong.
Above-mentioned purpose of the present invention is achieved by the following technical programs.
A kind of tundish heat preserving agent, each composition weight proportioning of this heat preserving agent is bicarbonate calcium powder 5 ~ 8%; Sodium hydrogen carbonate powder 14 ~ 29%; Rhenium metal powder 1-2%; Carbonic acid zirconium powder 1%; Potassium nitrate 5 ~ 16%; Chinese parasol tree tree sawdust powder 25 ~ 35%; Plant ash 15 ~ 30%; Metal iron powder 9 ~ 17%; Calcium carbide powder 5 ~ 8%.
The technical program is that this heat preserving agent substitutes conventional graphite powder, the constant but not carburetting of function.
Heat preserving agent provided by the present invention self can produce insulation, the effect of heat insulation that heat is conducive to improving heat preserving agent, the more important thing is the condensing rate being conducive to delaying casting matrix riser metal liquid, also can strengthen the ability that heat preserving agent absorbs metal liquid impurity simultaneously.This heat preserving agent can be widely used in tundish.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described:
Embodiment 1
