Abstract
The utility model provides a steelmaking pouring argon protective device. The steelmaking pouring argon protective device comprises a pouring mould body, an argon inlet pipe and 6-10 argon outlet pipes communicated with the argon inlet pipe are arranged at a pouring gate of the pouring mould body, the argon outlet pipes are uniformly distributed at the pouring gate of the pouring mould body, diameter of the argon inlet pipe is 3-6 cm, the diameter of each argon outlet pipe is 1-2 cm, and each argon outlet pipe stretches into the pouring gate for 2-3 cm. The steelmaking pouring argon protective device can effectively prevent secondary oxidation of molten steel in the pouring gate.
Description
Technical field
The utility model relates to a kind of pouring in steel smelting device, the anti-oxidation argon protective device of using of especially a kind of pouring in steel smelting.
Background technology
In the time carrying out pouring in steel smelting, because the molten steel of cast directly contacts with air ground, can cause the secondary oxidation of steel of cast, thereby cause the Quality Down of steel-making.
Summary of the invention
The technical problems to be solved in the utility model be cast molten steel and air directly contact the problem of the secondary oxidation of steel that causes cast.
In order to solve the problems of the technologies described above; the utility model provides a kind of pouring in steel smelting argon protective device; comprise casting mold body; the argon gas escape pipe that the sprue gate place of casting mold body is provided with argon inlet pipe and communicates with argon inlet pipe; the quantity of argon gas escape pipe is 6 ~ 10, and is evenly arranged in the sprue gate place of casting mold body, and the diameter of argon inlet pipe is 3 ~ 6 centimetres; the diameter of argon gas escape pipe is 1 ~ 2 centimetre, and the length that argon gas escape pipe puts in sprue gate is 2 ~ 3 centimetres.
Adopt argon gas escape pipe to be evenly arranged in sprue gate place, make molten steel in sprue gate because argon gas and air separate, effectively prevented the molten steel generation secondary oxidation in sprue gate; The diameter of argon inlet pipe is set to 3 ~ 6 centimetres, and the diameter of argon gas escape pipe is set to 1 ~ 2 centimetre, can meet the air inlet of argon gas and the requirement of giving vent to anger completely; The length that argon gas escape pipe puts in sprue gate is set to 2 ~ 3 centimetres, touches argon gas escape pipe can prevent pouring molten steel time, argon gas escape pipe is damaged or stop up.
The beneficial effects of the utility model are: adopt argon gas escape pipe to be evenly arranged in sprue gate place, make molten steel in sprue gate because argon gas and air separate, effectively prevented the molten steel generation secondary oxidation in sprue gate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1; pouring in steel smelting argon protective device of the present utility model comprises casting mold body 1; the argon gas escape pipe 3 that is provided with argon inlet pipe 2 at the sprue gate place of casting mold body 1 and communicates with argon inlet pipe 2; the quantity of argon gas escape pipe 3 is 6 ~ 10; be preferably 8; and be evenly arranged in the sprue gate place of casting mold body 1; the diameter of argon inlet pipe 2 is set to 3 ~ 6 centimetres; be preferably 4 centimetres; the diameter of argon gas escape pipe 3 is 1 ~ 2 centimetre; be preferably 2 centimetres, the length that argon gas escape pipe 3 puts in sprue gate is 2 ~ 3 centimetres, is preferably 3 centimetres.
This pouring in steel smelting argon protective device is in the time of work; first argon inlet pipe 2 is connected with argon gas source; in the time carrying out pouring molten steel; open the switch of argon gas source; pass into argon gas; argon gas sprays from 8 argon gas escape pipes 3 through argon inlet pipe 2; because the molecular weight of argon gas is greater than the molecular-weight average of air; so argon gas will sink and cover the molten steel top in sprue gate; separate contacting of molten steel and air; thereby there is secondary oxidation phenomenon in the molten steel that has effectively prevented cast, molten steel, after casting complete, is closed the switch of argon gas source.
Claims (1)
