Abstract

The invention discloses a casting technique of a novel rare-earth tellurium-copper alloy casting, which comprises the following steps: 1. preheating copper to 100-200 DEG C, adding into a reverberatory furnace, covering the copper material by using coke as a covering agent, sealing the fire hole, and melting the copper by heating; 2. when the burden in the reverberatory furnace is thoroughly molten, adding a deoxidizer and a refining agent, adding alloy elements tellurium and cerium, heating and removing the surface scum; and 3. cooling to 1180-1280 DEG C, casting, and cooling to obtain the rare-earth tellurium-copper alloy casting. The rare-earth tellurium-copper alloy casting obtained by the casting technique has the advantages of smooth surface and obviously longer service life than the common copper alloy material.

Description

The casting technique of novel rare-earth tellurium copper alloy-steel casting
 
Technical field
The present invention relates to a kind of casting technique of alloy-steel casting, be specifically related to a kind of casting technique of novel rare-earth tellurium copper alloy-steel casting.
 
Background technology
Copper and its alloy has high heat conduction, conduction, corrosion resistance nature, and good manufacture processing characteristics, is thus widely used in many fields such as electric power, electrician, machinery, space flight.But along with these new and high technologies are day by day harsh to the requirement of material property, traditional copper alloy material can not meet service requirements in certain fields, especially need to meet the over-all properties such as high strength & high electric-conduction, anti-oxidant heat/corrosion resistance occasion simultaneously, electrode, contact material etc. as various welding machine had both required to keep excellent conductivity, had higher physical strength again; The heat resistant copper alloy of Iron And Steel Industry, be mainly used in the component such as such as blast-furnace tuyere, oxygen lance shower nozzle, electrode jaw, contact fixture and crystallizer, not only need to possess certain physical strength, also will possess the over-all propertieies such as good high-temperature oxidation resistance, high softening temperature, good electroconductibility.The foundry technology process of coarse rare earth tellurium copper alloy-steel casting is very complicated, and expect that very bright and clean surperficial degree exists certain difficulty, thus its use range is subject to certain restrictions.
 
Summary of the invention
The object of the invention is to, a kind of casting technique of novel rare-earth tellurium copper alloy-steel casting is provided, gained rare earth tellurium copper alloy-steel casting any surface finish, and significantly improve than ordinary copper alloy material its work-ing life.
The casting technique of described novel rare-earth tellurium copper alloy-steel casting, it comprises the following steps:
One, copper is preheated to 100 DEG C-200 DEG C, adds in reverberatory furnace, make insulating covering agent covering copper material with coke, fire door of obturaging, be heated to copper melting;
Two, when the furnace charge in reverberatory furnace thoroughly melts, add reductor and refining agent, then add alloying element tellurium and cerium, heat up, remove surface scum;
When three, being cooled to 1180 DEG C-1280 DEG C, pour into a mould, cool and obtain rare earth tellurium copper alloy-steel casting.
The casting technique of novel rare-earth tellurium copper alloy-steel casting provided by the invention, its beneficial effect is, gained rare earth tellurium copper alloy-steel casting any surface finish, and significantly improves than ordinary copper alloy material its work-ing life.
 
Embodiment
Below in conjunction with an embodiment, the casting technique of novel rare-earth tellurium copper alloy-steel casting provided by the invention is described in detail.
 
Embodiment
One, copper is preheated to 150 DEG C, adds in reverberatory furnace, make insulating covering agent covering copper material with coke, fire door of obturaging, be heated to copper melting;
Two, when the furnace charge in reverberatory furnace thoroughly melts, add reductor and refining agent, then add alloying element tellurium and cerium, heat up, remove surface scum;
When three, being cooled to 1180 DEG C, pour into a mould, cool and obtain rare earth tellurium copper alloy-steel casting.
