Abstract
The invention provides a type of liquid agent for thermal protection and removing residue in metals, characterized in that the agent is produced through the flowing technologies: It uses perlite as raw material. Dry the perlite under a temperature between 200-1100 DEG C for 2-30 minutes. The above mentioned perlite is 12-100 mesh. Perlite of 18-20 mesh can be used for removing residues in a precision casting furnace and the external ladle. Perlite of 20-70 is suitable for removing residues in steel-casting, iron-casting and molten iron ladle. The technologies covered by this invention are simple and the agent for thermal protection and residue-removing is effective in purifying liquid metal, improving quality of cast and reducing the ratio of defective cast.
Description
Technical field: the present invention relates to a kind of metal casting process thermal insulation deslagging agent that is used for.
Background technology: perlite is usually used in the thermal insulation deslagging agent in the metal casting process, but common perlite in use reduces the temperature of molten iron easily owing to contain moisture, influences casting quality.
Summary of the invention: purpose of the present invention is exactly the deslagging agent that a kind of high insulating effect is provided at above-mentioned situation.
Purpose of the present invention can realize by following scheme.
With the perlite is raw material, it is dried got final product in 2-30 minute under 200-1100 ℃ high temperature.
Optimum temperature 400-700 ℃, drying time 4-5 minute.
Described perlitic size is the 12-100 order.
Wherein the perlite of 18-20 order size is used in the hot investment casting electric furnace and slagging-off in the stove outsourcing, and the 20-70 order is used for slagging-off in the bags such as cast steel, cast iron, molten iron.
Technology of the present invention is simple, and the thermal insulation deslagging agent result of use that produces is good, to purifying liquid metal, improves casting quality, reduces the casting wasted product rate and can both play good action.
