Abstract
The invention discloses a thermal treatment technology of a nickel-based high temperature alloy casting. The thermal treatment technology comprises the following steps: mixing, modeling, smelting, pouring, welding repair and polishing, wherein the pouring raw material comprises the following components in parts by weight: 8-20 parts of Cr, 25-35 parts of C, 10-15 parts of Mn and 5-15 parts of rare earth elements. Through the adoption of the thermal treatment technology of the nickel-based high temperature alloy casting, the phenomena of cracks and cracking can be effectively reduced, and the performance stability of the product can be improved.
Description
Technical field
The present invention relates to technical field of hardware, be specifically related to a kind of thermal treatment process of nickel base superalloy foundry goods.
Background technology
Alloy-steel casting is widely applied in China, is mainly used in the fields such as mineral products, machinery, building materials, belongs to rapid wear wearing piece.Such as the alloy-steel casting of vertical mill liner plate, because industrial and mineral bad environments, require very high to the wear resisting property of material.Existing alloy-steel casting is owing to adding metal component and the irrational reason of each component proportion, and the component concentration of such as chromium is on the low side, effectively can not improve the hardness of alloy-steel casting, have impact on the wear resisting property of foundry goods.In addition, existing alloy-steel casting is owing to only carrying out a thermal treatment in process of production, temperature is at about 900 DEG C, cannot effectively eliminate the internal stress produced in production process, cause foundry goods can crack or crack performance in long-time use procedure, the unstable properties of foundry goods, also can have influence on the work-ing life of foundry goods.
Summary of the invention
Instant invention overcomes above-mentioned shortcoming, and a kind of thermal treatment process of nickel base superalloy foundry goods is provided.
To achieve these goals, the present invention realizes by the following technical solutions: the thermal treatment process of this nickel base superalloy foundry goods comprises the following steps: mixing, moulding, smelting, cast, soldering, polishing.
The weight part that described cast raw material comprises each raw material is respectively: Cr8 ~ 20 part, C25 ~ 35 part, Mn10 ~ 15 part, 5 ~ 15 parts, rare earth element.
Preferably, the weight part of described each raw material is respectively: Cr8 part, C25 part, Mn10 part, 5 parts, rare earth element.
Preferably, the weight part of described each raw material is respectively: Cr15 part, C30 part, Mn12 part, 10 parts, rare earth element.
Preferably, the weight part of described each raw material is respectively: Cr20 part, C35 part, Mn15 part, 15 parts, rare earth element.
Preferably, described rare earth element is any one in Gd, Tb, Dy, Ho.
The invention has the beneficial effects as follows: can effectively reduce the phenomenon such as crackle, be full of cracks, and stability of enhancing product performance.
