Abstract

An efficient heat-gaining agent for delaying the solidification of molten metal in casting is prepared from aluminium (or Al alloy, or magnesium) powder, Si-Ca powder, oxidizing heat-gaining agent, refractory slag-forming material and metallic oxide (or ore) powder through mixing in proportion. Said metallic oxide powder may be the one of Cu, Fe, Ni or Co, which are respectively used in casting of Cu or Cu-alloy, alloy steel, stainless steel, refractory Fe-base alloy, Ni-base alloy, or Co-base alloy. Its advantages include high finished product rate, basically eliminating shrinkage cavity and loose defects, and no pollution to metal.

Description

Efficient heat-generating agent for delay solidification of molten metal
Advantage of the present invention: have wide range of applications; Substantially eliminate with casting shrinking hole behind this exothermic mixture and defective such as loose, improved yield rate greatly, can thoroughly solve the casting problem of the too near difficult cast alloys of some liquid-solid phase temperature difference; Do not pollute the cast metal, do not change the cast metal chemical analysis.
Embodiments of the invention:
Get: aluminium powder 12% (granularity is that 0.5mm is following)
Silicon calcium powder 15%
Potassium chlorate 2%
Spinelle, calcium oxide, alumina powder 27%
Brown iron oxide 44% (granularity is that 0.5mm is following)
Owing to adopt brown iron oxide, can be directly used in steel alloy, in the casting die moulding of stainless steel or iron-base superalloy.

Claims (1)

1. efficient heat-generating agent that is used for delay solidification of molten metal is characterized in that this exothermic mixture is raw materials used and is:
