Abstract
Cast the invention discloses one kind with inexpensive compound molten steel screen pack factory formula, it is made up of according to weight fraction the following raw material, 65 75 parts of carborundum, 20 30 parts of silica flour, 37 parts of ceramic powder, the present invention is using carborundum as major ingredient, silica flour is auxiliary material, ceramic powder is high temperature compound phase, silica flour and ceramic powder lifting product resistance to elevated temperatures, major defect：Thermal conductivity factor is big.Carborundum is that major ingredient refractoriness is low, and thermal conductivity factor is low.Two kinds of Material claddings ensure that refractoriness is high, and thermal conductivity factor is low, and screen pack production can be achieved, available for resin filter net and zirconium English screen pack is substituted, product surface quality is solved the problems, such as.
Description
Technical field
It is specially that a kind of casting is produced with inexpensive compound molten steel screen pack the present invention relates to filter screen production technical field
Formula.
Background technology
Currently for automobile casting manufacturing enterprise, due to a series of spies such as the complexity of casting structure, thin wall type, lightweight
Point so that a series of product surfaces of full form casting process production and internal slag stomata.Because pouring molten steel temperature is up to 1630
DEG C so that the molten steel screen pack of industry industry at present mainly has resin fibre screen pack, zirconium English screen pack.Due to above two
Type screen pack is expensive, is difficult popularization and application in general foundry enterprise, product surface quality lifting is seriously restricted.Open
Send out the compound molten steel screen pack of novel low-cost imperative, on the premise of low cost is produced, product table is lifted to greatest extent
Face quality.
The content of the invention
To achieve the above object, the present invention provides following technical scheme：One kind casting is filtered with inexpensive compound molten steel
Net factory formula, is made up of according to weight fraction the following raw material：
65-75 parts of carborundum, 20-30 parts of silica flour, 3-7 parts of ceramic powder.
It is preferred that, it is made up of according to weight fraction the following raw material：
65 parts of carborundum, 20 parts of silica flour, 3 parts of ceramic powder.
It is preferred that, it is made up of according to weight fraction the following raw material：
70 parts of carborundum, 25 parts of silica flour, 5 parts of ceramic powder.
It is preferred that, it is made up of according to weight fraction the following raw material：
75 parts of carborundum, 30 parts of silica flour, 7 parts of ceramic powder.
It is preferred that, the carborundum, silica flour, the mesh number point of ceramic powder are than being 270,270,300 mesh.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is using carborundum as major ingredient, and silica flour is auxiliary material,
Ceramic powder is high temperature compound phase, silica flour and ceramic powder lifting product resistance to elevated temperatures, major defect：Thermal conductivity factor is big.Carbonization
Silicon is that major ingredient refractoriness is low, and thermal conductivity factor is low.Two kinds of Material claddings ensure that refractoriness is high, and thermal conductivity factor is low, and screen pack can be achieved
Production, available for resin filter net and zirconium English screen pack is substituted, solves the problems, such as product surface quality.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
