Abstract
The utility model relates to degas pipe with strong durability for aluminum smelting, which is characterized in that: the original straight pipe is changed into a bent pipe with certain angle, therefore reduces the length and area that the steel pipe directly connects the aluminum liquid; the part connected with the aluminum liquid is covered with the fireproof layer, which greatly decreases the heat that the aluminum liquid transfers to the steel pipe, thereby strengthening the service life of the degas pipe.
Description
Technical field
The utility model relates to aluminium manufacture field technical field, and specifically a kind of wearing quality is strong is used for the gas removing pipe of aluminium melting (comprise that aluminium casting, aluminothermy are rolled, aluminum casting, round aluminum rod etc.).
Background technology
When the aluminium melting, contained hydrogen in the aluminium liquid, can cause and be mingled with a large amount of pin holes in the aluminium converted products, directly have influence on aluminium quality product and safety, and the existence of hydrogen also can form a certain amount of slag inclusion (it is generally acknowledged the symbiosis of slag gas), so will remove hydrogen contained in the aluminium liquid as much as possible, the most frequently used method is to feed nitrogen or chlorine in the aluminium liquid, removes hydrogen in the aluminium liquid by chemical reaction.Will be input to nitrogen in the aluminium liquid, need harrow with the degasification that a steel pipe or steel pipe are made, afterbody connects nitrogen pipeline, and front end extend in the aluminium liquid.Because steel pipe can melt and react with oxygen in aluminium liquid, therefore a degasification can only be about 15 minutes, and one eradicates tracheae can only use secondary at most, and the consumption of a large amount of steel pipes has not only increased cost but also influenced aluminium liquid alloy ingredient.
Summary of the invention
The purpose of this utility model provides the strong gas removing pipe that is used for the aluminium melting of a kind of wearing quality.
The technical solution of the utility model is: change original straight tube the bend pipe of certain angle into, and the part that will contact with aluminium liquid wraps flame retardant coating, flame retardant coating comprises refractory fiber floor and refractory masses.
The gas removing pipe that is used for the aluminium melting of the present utility model changes original straight tube the bend pipe of certain angle into, thereby reduces length or area that steel pipe and aluminium liquid directly contact; And the part that will contact with aluminium liquid wraps flame retardant coating, reduces the heat that aluminium liquid transmits to steel pipe greatly, uses refractory fibre mainly to rise heat insulation and prevents that steel pipe from bursting refractory materials.Thereby strengthened the work-ing life of gas removing pipe.
Description of drawings
Fig. 1 is a gas removing pipe structural representation of the present utility model.
Among the figure, 1-(special processing) steel pipe, 2-refractory fiber floor, 3-refractory masses.
Embodiment
Elder generation bends the steel pipe of special processing and has a certain degree (angle suitably gets final product), wraps refractory fiber floor then, and outermost layer is wrapped refractory masses again, as shown in Figure 1, can use after the thorough drying.
Claims (2)
1, the gas removing pipe that is used for the aluminium melting that a kind of wearing quality is strong is characterized in that gas removing pipe is the bend pipe that an end is converted into certain angle, and the straight-tube portion of aluminium liquid contact is wrapped flame retardant coating.
2, the gas removing pipe that is used for the aluminium melting that wearing quality according to claim 1 is strong is characterized in that flame retardant coating comprises refractory fiber floor and refractory masses.
