Abstract
The invention discloses the coating structures that one kind can promote surface quality of continuous castings, raw material including following parts by weight: 15-18 parts of silicon dioxide powder, 1.1-1.3 parts of binder, 3-5 parts of activating agent, 4-5 parts of iron oxide, 3-5 parts of lubricant, 10-15 parts of solvent, the binder is phenolic resin, the lubricant is calcium stearate, and the solvent is the mixture that methanol and ethyl alcohol are configured in 1:1 ratio.Type inner cavity surface of the present invention by coating brush in casting sand type can prevent scab, and the ability for being attached to mould surface is strong, and drying time 1min or so has no substantial effect on the implementation of normal casting process, ensure that higher processing efficiency；Final surface quality of continuous castings, which has, to be obviously improved, and the material price used is cheaper, ensure that lower processing cost.
Description
Technical field
The present invention relates to a kind of coating, specifically a kind of coating structure for promoting surface quality of continuous castings belongs to casting and adds
Work field.
Background technique
In the casting processing of the materials such as steel, aluminium, it often will appear the case where scab leads to uneven surface, be
Solution this problem, can only select the molding sand of better quality as far as possible, this undoubtedly improves the cost of casting processing, and for casting
The raising of part surface quality is very limited.
Summary of the invention
It can be medium-sized to avoid casting process in view of the above-mentioned problems of the prior art, the object of the present invention is to provide one kind
Sand is adhered to uneven surface phenomenon caused by cast(ing) surface, and not will increase casting processing cost and promote surface quality of continuous castings
Coating structure.
To achieve the above object, the technical solution adopted by the present invention is that: one kind can promote the coating knot of surface quality of continuous castings
Structure, the raw material including following parts by weight: 15-18 parts of silicon dioxide powder, 1.1-1.3 parts of binder, 3-5 parts of activating agent, iron oxide
4-5 parts, 3-5 parts of lubricant, 10-15 parts of solvent, the binder are phenolic resin, and the lubricant is calcium stearate, described
Solvent is the mixture that methanol and ethyl alcohol are configured in 1:1 ratio.
Preferably, the granularity of the silicon dioxide powder is 200-300 mesh.
Preferably, the raw material including following parts by weight: 16 parts of silicon dioxide powder, 1.3 parts of binder, 5 parts of activating agent, oxidation
5 parts of iron, 3 parts of lubricant, 10 parts of solvent.
Preferably, the coating structure with a thickness of 0.4-0.5mm.
Type inner cavity surface of the present invention by coating brush in casting sand type can prevent scab, be attached to the ability of mould surface
By force, drying time 1min or so has no substantial effect on the implementation of normal casting process, ensure that higher processing efficiency；Finally
Surface quality of continuous castings have and be obviously improved, and the material price used is cheaper, ensure that lower processing cost.
Specific embodiment
Below with reference to embodiment, invention is further described in detail.
