Description
【Technical field】
The present invention relates to aluminium and aluminium alloy casting field, and in particular to a kind of aluminium liquid mozzle.
【Background technology】
In aluminium and aluminium alloy Foundry Production, it is often necessary to aluminium liquid is delivered into the other end by one end by conduction pipe.
Existing aluminium liquid mozzle is mostly made with metal or the material based on metal, due to making material and its original of manufacture craft
Cause, the coefficient of heat conduction is high, and tube wall is easy to adhere to aluminium liquid, and during conveying aluminum liquid, the temperature of aluminum liquid range of decrease is too big and can not expire
Sufficient delivery requirements, aluminium liquid can continuous cooled and solidified water conservancy diversion inside pipe wall influence pipeline conveying capacity in addition block mozzle
Road.During reuse, this phenomenon is particularly evident.
【The content of the invention】
For above-mentioned existing technical problem, it is necessary to which aluminium liquid high temperature can not only be born by providing one kind, be kept high-strength
Spend indeformable, and the coefficient of heat conduction is low, good heat preservation performance, and inwall is not easy to tie the mozzle of aluminium block.
The technical solution used in the present invention is：
A kind of aluminium liquid mozzle, the aluminium liquid mozzle are calcium silicate material, and preparation method comprises the following steps：Take appropriate cunning
Stone flour, add water to be slurried, the aluminium liquid mozzle of the calcium silicate material is put into talcum powder slurries immersion 15-20min, dragged for
Go out the aluminium liquid mozzle, 50-60min is toasted under conditions of being 80-100 DEG C in temperature.
Further, a kind of aluminium liquid mozzle, the calcium silicate material are mainly made up of following raw material：Silica flour, ripe stone
Ash, portland cement and magnesia, its preparation method step are as follows：
S1：Take each raw material by mass parts, silica flour 50-65 parts, white lime 30-40 parts, portland cement 12-15 parts,
Magnesia 4-8 parts, add water to be stirred into slurry；
S2：Slurry obtained by S1 is injected mould, sample blanks is dehydrated into, sample blanks pressure 1.2-2.0MPa, temperature 250-
300 DEG C of steam curing 45-60min；
S3：Appropriate talcum powder is taken, adds water to be slurried, the sample blanks of the calcium silicate material obtained by S2 is put into talcum powder slurries
15-20min is soaked, pulls the sample blanks out, baking 50-60min produces the aluminium liquid and led under conditions of being 80-100 DEG C in temperature
Flow tube.
Further, a kind of aluminium liquid mozzle, the calcium silicate material are mainly made up of following raw material：Silica flour, ripe stone
Ash, portland cement and magnesia, its preparation method step are as follows：
S1：Take each raw material by mass parts, silica flour 50-65 parts, white lime 30-40 parts, portland cement 12-15 parts,
Magnesia 4-8 parts, add water to be stirred into slurry；
S2：Slurry obtained by S1 is injected mould, sample blanks is dehydrated into, sample blanks pressure 1.2-2.0MPa, temperature 250-
300 DEG C of steam curing 45-60min, sample blanks is taken out, sample blanks is subjected to roasting 30-40min for 1000-1200 DEG C with temperature；
S3：Appropriate talcum powder is taken, adds water to be slurried, the sample blanks of the calcium silicate material obtained by S2 is put into talcum powder slurries
15-20min is soaked, pulls the sample blanks out, baking 50-60min produces the aluminium liquid and led under conditions of being 80-100 DEG C in temperature
Flow tube.
Preferably, talcum powder concentration of slurry is 40%.
Fa Benming has following good effect：
1. the aluminium liquid mozzle high temperature resistant, corrosion-resistant, high temperature aluminium liquid does not chemically react with the aluminium liquid mozzle.
2. the aluminium liquid mozzle still keeps very high intensity under the high temperature conditions, deformation is small, service life length.
3. the aluminium liquid mozzle coefficient of heat conduction is extremely low, ensure that aluminium liquid and external heat conduction are few, during water conservancy diversion,
The temperature of aluminum liquid range of decrease is low；Furthermore the aluminium liquid water conservancy diversion inside pipe wall is not easy to adhere to aluminium liquid, and aluminium liquid is not easy in inner tubal wall or opening
Form aluminium block, aluminium liquid water conservancy diversion is unobstructed, and Reusability still keeps good effect.
