Description
Technical Field
The utility model relates to a pouring cup special for a large-diameter hole-covered cast steel roller, and belongs to the technical field of roller casting in the metallurgical industry.
Background
With the rapid development of science and technology, roller performance and quality are increasingly emphasized. Pouring cups are basic components for casting roll technology, have extremely close relation with the development of metallurgical industry in particular, and are one of important components of smelting process equipment. The pouring cup is used for containing the poured molten metal and relieving the impact of the liquid metal on the casting mould, so that the molten metal smoothly flows into the sprue and into the roller casting mould cavity. The existing pouring cup is mainly made of sand molds, so that the defects of air holes, sand holes, iron beans, slag blister, shrinkage holes, cracks, insufficient pouring and the like of castings are easily generated in the pouring process, the product quality of the roller is affected, and the pouring cup cannot be reused.
Disclosure of utility model
The utility model aims to provide a pouring cup special for a large-diameter hole-covered cast steel roller, which can improve the erosion resistance strength in a cavity, reduce the content of molten steel inclusions, ensure the quality of a roller product, prolong the service life of the pouring cup and solve the problems in the background art.
The technical scheme of the utility model is as follows:
The utility model provides a special pouring basin of major diameter package hole pouring cast steel roll, contains shell, ladle castable, resistant firebrick and base, and the shell is fixed on the base, the shell upper half is the rectangle, and the latter half is big-end-up's frustum shape, pouring ladle castable on the inner wall of shell, laying bricks on the ladle castable, forming the pouring basin die cavity, pouring basin die cavity upper half is big-end-up's ellipse, and the latter half is big-end-up's round platform shape.
And the shell is provided with a lifting lug.
The two lifting lugs on the shell are fixed on two sides of the shell and are symmetrically arranged.
And the base is provided with a through hole matched with the pouring cup cavity.
The beneficial effects of the utility model are as follows: during pouring, molten steel can directly enter the cavity, the molten steel can not overflow from the cavity in the pouring cup, and the pouring cup can be used repeatedly, so that the labor intensity of workers is reduced. The improvement of the scouring resistance strength greatly reduces the inclusion of molten steel, ensures the purity of molten steel and improves the quality of the roller.
Drawings
FIG. 1 is a front view of the present utility model;
FIG. 2 is a top view of the present utility model;
FIG. 3 is a schematic view of the present utility model in use;
In the figure: 1. lifting lugs; 2. a housing; 3. ladle casting material; 4. refractory bricks; 5. a base; 6. a ladle; 7. molten steel; 8. and (3) a straight pouring channel.
Detailed Description
The utility model is further illustrated by way of example with reference to the accompanying drawings.
Referring to fig. 1-3, a pouring cup special for pouring cast steel rolls through a large-diameter ladle hole comprises a shell 2, ladle castable 3, refractory bricks 4 and a base 5, wherein the shell 2 is fixed on the base 5, the upper half part of the shell 2 is rectangular, the lower half part of the shell is in a frustum shape with a large upper part and a small lower part, the ladle castable 3 is poured on the inner wall of the shell 2, the refractory bricks 4 are built on the ladle castable 3 to form a pouring cup cavity, the upper half part of the pouring cup cavity is in an oval shape with the large upper part and the small lower part, and the lower half part of the pouring cup cavity is in a round table shape with the large upper part and the small lower part.
In this embodiment, referring to fig. 1 to 3, the housing 2 is formed by welding a common carbon steel plate, and the lifting lug 1 and the base 5 are thickened common carbon steel plates. The shell 2 is welded on the base 5, and two lifting lugs 1 are respectively welded on the shell 2 and are symmetrically arranged.
The shell 2 is built by a ladle casting material 3 and a common refractory brick 4, and forms a pouring cup cavity. The size of the pouring cup body and the size of the cavity are determined according to the size of the concrete ladle hole.
Referring to FIG. 3, the diameter of a ladle hole of the ladle is set to be 100mm, the diameter of the lower end of a pouring cup cavity is set to be 120mm, the height of the pouring cup is set to be 900mm, and the radius of the upper end of the pouring cup cavity is set to be 300-500mm. During casting, the chassis 5 is connected with the sprue 8.
The density ρ Molten steel =7.3g/mm3 of molten steel.
The pouring cup volume V pouring cup =0.135m3 is calculated, and the weight of molten steel can be contained in the pouring cup every time, namely about 985 kg.
The utility model can be repeatedly used for 30 times, effectively prolongs the service life and reduces the labor intensity of workers. Refractory bricks are built in the pouring cup, so that the flushing resistance of the pouring cup is improved, and the purity of molten steel is ensured.
