Description
Technical Field
The utility model relates to a floating force adjusted pushing off slag pouring basin belongs to casting technical field.
Background
During the pouring of the cast steel, the steel is poured into the mould cavity through a pouring cup, which is usually a funnel-shaped pouring nozzle, made separately or directly in the mould, becoming an enlarged part of the sprue top. The part is the first contact gate for molten steel injection. At present, a pouring cup which is commonly adopted in the industry is a sand-type pouring cup, a funnel-type die is adopted, resin sand is used for manufacturing, and the pouring cup is molded after the resin sand is solidified.
Molten steel can generate certain steel slag during smelting, the steel slag is poured into a steel ladle after tapping, the steel slag cannot be completely removed through deslagging operation, and a small amount of steel slag still floats on the surface of the molten steel due to the fact that the density of the steel slag is lower than that of the molten steel.
The pouring cup is the first contact position of molten steel entering a casting mold, and due to the improper design of the pouring cup, scum on the surface of the molten steel enters a cavity during pouring, so that the defect of slag inclusion casting is generated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the scum on the surface of the molten steel can enter the cavity when the traditional sprue cup is poured, producing the defect of slag inclusion casting, and providing a floating force-adjusted slag-stopping sprue cup for this purpose.
The utility model aims at realizing through the following technical scheme:
the utility model relates to a floating force adjusting slag-stopping pouring basin, which comprises a pouring basin body, a slag-stopping plate and a floating limit platform;
the upper end of the pouring cup body is provided with a cavity for containing molten steel, and the side wall of the middle part of the pouring cup body cavity is symmetrically provided with slag trap limiting grooves; the slag trap is arranged in the middle of the pouring cup body cavity through a slag trap limiting groove, so that the pouring cup body cavity is divided into a settling zone and a pouring zone; the lower end of a pouring area in the cavity of the pouring cup body is provided with a pouring hole; the bottom of the cavity of the pouring basin body is provided with a slag trap buoyancy cavity, when the slag trap slides to the bottom of the cavity of the pouring basin body along a slag trap limiting groove, one end of the bottom surface of the slag trap is lapped on the bottom surface of the sedimentation zone, and the other end of the bottom surface of the slag trap is suspended above the slag trap buoyancy cavity; the upper port part of the sprue cup body is provided with a floating limit platform;
when the buoyancy of the molten steel contained in the settling zone to the slag trap is larger than the gravity of the slag trap, the slag trap floats upwards to communicate the settling zone with the bottom of the pouring zone, and the floating height of the slag trap is limited by the floating limiting table.
Working process
Before the pouring cup is used, the inner cavity of the pouring cup body and two sides of the slag trap are coated with refractory paint, after the pouring cup body is dried, the pouring cup body is placed at the top of the sand box, the pouring hole is aligned with the sprue in the sand box, and the pouring cup body is fixed. And inserting the slag trap into the lowest end of the inner cavity of the pouring cup body to divide the inner cavity of the pouring cup body into a settling zone and a pouring zone. When pouring, the ladle opening is aligned to the settling zone, the molten steel is firstly poured into the settling zone, the liquid level continuously floats upwards, the steel slag floats above the molten steel in the settling zone due to the fact that the density of the steel slag is lower than that of the molten steel, the buoyancy of the molten steel contained in the settling zone to the slag trap is smaller than the self gravity of the slag trap, and the bottom of the settling zone is isolated from the pouring zone, so that the molten steel is fully settled in the settling zone. When molten steel is poured into a settling zone to about 2/3, the buoyancy of the molten steel contained in the settling zone to the slag trap is larger than the gravity of the slag trap, the slag trap floats upwards, the bottom of the settling zone is communicated with the pouring zone, and the slag trap floats upwards under the limit of the upwards-floating limit platform, so that the lifting height of the bottom of the slag trap is 30-40 mm; and the precipitated molten steel overflows to a pouring area from the bottom of the slag trap and enters the cavity of the sand box through a pouring hole. And continuously injecting the molten steel into the settling zone to keep the liquid level of the molten steel at about 2/3 until the casting is finished.
Advantageous effects
1. The sprue cup of the utility model increases the function of slag blocking and filtering, and can solve the problem that the slag enters the cavity along with the molten steel during pouring to cause slag inclusion of the casting;
2. the density of the slag trap is smaller than that of molten steel, the slag trap floats upwards and is limited by buoyancy, automatic slag trap control is realized, and the operation is simple and safe;
3. the utility model discloses a pouring basin simple structure, convenient for material collection, the preparation degree of difficulty is low, but uses in batches.
