Abstract
The invention relates to a hardening agent, in particular to an investment casting composite hardening agent. The investment casting composite hardening agent is prepared from the following raw materials in parts by weight: 70 to 80 parts of crystalline magnesium chloride, 45 to 65 parts of ammonium chloride, 0.1 to 0.5 part of stearic acid and 0.2 to 0.8 part of paraffin. The investment casting composite hardening agent provided by the invention consists of multiple components which are compounded. When the investment casting composite hardening agent is applied to sodium silicate sand casting, the cast piece has high finished product ratio, excellent surface quality and excellent dimensional precision.
Description
Technical field
The present invention relates to a kind of curing agent, be specifically related to lost-wax composite hardener.
Background technology
In model casting, sodium silicate binder is general prepares slurry with silica flour, spreads quartz sand, chemicosolidifying in ammonium chloride solution and crystallization magnesium chloride solution, and the investment shell intensity that this technique makes is not high, and surface roughness and the dimensional accuracy of foundry goods are poor.
Summary of the invention
For above-mentioned technical problem, the invention provides the curing agent that surface quality of continuous castings and dimensional accuracy can be provided.
For solving the problems of the technologies described above, the technical scheme that Bian of the present invention uses is as follows:
Lost-wax composite hardener, is prepared according to weight portion by following raw material, 70～80 parts of crystallization magnesium chloride, 45～65 parts of ammonium chlorides, 0.1～0.5 part of stearic acid, 0.2～0.8 part, paraffin.
Optimal design is, 77 parts of crystallization magnesium chloride, 56 parts of ammonium chlorides, 0.35 part of stearic acid, 0.58 part, paraffin.
Above raw material had both obtained lost-wax composite hardener after grinding and stirring.
Lost-wax composite hardener provided by the invention, forms by various ingredients is compound, and when for the husky casting of waterglass, casting yield is high, and surface quality of continuous castings and dimensional accuracy are good.
