short description:

The inner surface of the crucible is coated with a coating containing rare earth oxide. The invention also provides a treatment method of the high-temperature melting crucible and its application in the high-temperature alloy melting process. The melting crucible of the invention has long service life, good melting effect and easy slag cleaning after repeated use, It can make the melting crucible form a high temperature resistant protective film in the melting process, effectively prevent the erosion of Superalloy solution on the crucible, improve the service life of the crucible, facilitate the cleaning of material slag and improve the production efficiency. It can be widely used in the field of alloy high temperature melting.

Rare Oxide Composite Ceramic Smelting Crucible

Ti-alloy material is the composed alloy of adding other element based on Ti. Ti and Ti- Alloys Products have strong strength, high smelting point, low density, excellent erosion and heat resistance, good mechanical properties, toughness, etc. features, then widely used in the aviation industry, as compressor component of aircraft engine, structure component of rocket, missile, high speed aeroplane, etc. industries.

Casting Technology of Ti- Alloy Products can reveal the industry strength of one country. The limited term of casting is low chemical reacted with other materials at under high-temp. Terms.When casting, it is necessary to adopt HP super Hi-Temp. Material,which could not be wetted and adhered with Ti and Ti- Alloy. HP Y203, HP Y203-Zr02 Solid Solution, HP Barium Zirconate, etc. Ceramic Materials can satisfy the exacting casting term for the Ti & Ti-Alloy products.

 Their working temperature is from 1600-2300 deg.cel. Do not adhere and wet with Ti& Ti- Alloy metal liquids.Excellent chemical stability and crushing resistance. It is the ideal new type material of casting metal Ti&Ti-Alloy, Precious Metal melting and casting industries.

Using the slope of the side wall, the crucible is very convenient to pour the molten metal in it, and the smooth arc bottom makes the metal in it basically reach the same temperature. Therefore, the crucible can save melting time.
