Abstract
The utility model discloses a die casting the argon protection pours into a mould device can reduce inclusion content in the steel to improve the quality of steel. The device includes: casing, pouring patchhole, intake pipe, feed trumpet and baffle, during the baffle is fixed in the casing, place the below of baffle in the intake pipe in, the casing lower part is connected to the feed trumpet, and intake pipe evenly distributed is peripheral at the casing, and the connecting pipe links to each other with the air supply through admitting air. The utility model discloses a protection is poured into a mould to the sealed device, forms the argon protection atmosphere in whole protection device, thoroughly avoids the air to get into the molten steel from pouring patchhole and feed trumpet junction to reduce total oxygen content in the steel, improve the pure degree of steel. The utility model has the advantages of simple structure, the strong operability.
Description
Technical field
The utility model relates to steel ingot casting device, particularly a kind of die casting argon for protecting pouring device.
Background technology
In recent years, Secondary Refining Technology obtains and develops rapidly, and modern smelting process can produce super clean molten steel.But molten steel is in casting process, and beam and atmosphere, will be involved in a large amount of air, and cause the secondary oxidation of molten steel.The temperature of the high-purity molten steel processed outward through stove is high, and the activity of oxygen is low, increases the weight of secondary oxidation phenomenon, makes to produce more oxide inclusion in the steel ingot that finally solidifies.So can this high cleanliness on final body becomes a useful person now, also depend on the perfect of protective casting technique.
Want in die casting to obtain high-quality steel, the field trash in molten steel must be reduced.In casting process, the secondary oxidation of molten steel is the main source of field trash, and molding casting, as the important measures improving steel product quality in die casting process, prevents the secondary oxidation of molten steel.Based on current die casting molding casting technology and device, or device is simple and without effect, or technical sophistication and cannot commercial Application, is difficult to reach the effect preventing secondary oxidation.Need to improve molding casting effect further, improve the device of molding casting, meet the requirement on ingot quality.
Utility model content
The utility model provides a kind of die casting argon for protecting pouring device, can reduce inclusion content of steel, thus improves the quality of steel.
A kind of die casting argon for protecting pouring device; it is characterized in that this device comprises: housing, mouth of a river patchhole, baffle plate, air inlet pipe, feed trumpet; described baffle plate is fixed in housing; air inlet pipe is built in the below of baffle plate; feed trumpet connects lower housing portion; air inlet pipe is evenly distributed on casing peripheral, is connected with source of the gas by inlet pipe connection.
Described a kind of die casting argon for protecting pouring device is made up of metal shell and Monofrax liner.
Described air inlet pipe is 3-10 round tube, and its diameter is 5-20mm, is 12-30mm with the distance of top baffle plate; Described baffle plate is tilted to down, becomes 0 ° of-30 ° of angle with horizontal plane, and between the sprue gate outer wall of baffle plate and insertion, gap is 3-15mm.
Described lower housing portion is circular arc-parallax-arc structure, and parallax is from the horizontal by 15 ° of-65 ° of angles.
Passing into flow in described housing is 20-35m
3the argon gas of/h, gas flow is 0 °-45° angle obliquely.
The utility model is compared with existing same device, and its beneficial effect is embodied in:
A kind of die casting argon for protecting pouring device characteristic, for add one piece of baffle plate in the housing, is divided into epicoele and cavity of resorption whole intracavity space, and cavity of resorption passes into argon gas can make up negative pressure and supply molten steel entrainments, and epicoele argon gas can cushion cavity of resorption molten steel and roll up gas degree; There is certain radian between housing and feed trumpet, make the argon gas of housing to be more easily involved in feed trumpet by molten steel like this, reduce entrainmenting epicoele argon gas simultaneously.Be conducive to like this forming argon atmosphere in protective device, thoroughly avoid air to enter molten steel from mouth of a river patchhole and feed trumpet junction, thus reduce entire oxygen content in the steel content, improve the degree of purity of steel.It is simple that the utility model has structure, the advantages such as strong operability.
