Abstract
A steel-making ladle capable of reducing residual molten steel in the ladle is provided with a ladle shell, a fire-resistant layer, a ladle bottom casting fire-resistant layer and a water gap; the ladle is in a conical shape with a large upper part and a small lower part, a refractory layer is arranged around the inner wall of the ladle, and a ladle bottom casting refractory layer is arranged on the surface of the refractory layer at the bottom of the ladle; a water gap is arranged at the bottom of the ladle; a water gap groove is formed in the upper part of the water gap; in the last stage of casting, the molten steel is collected into the water gap groove, and when the molten steel is subjected to vortex penetration, the ladle is closed, so that the residual molten steel in the ladle is reduced, the yield of casting blanks is further increased, the consumption of iron and steel materials is reduced, and the production cost is finally saved.
Description
Technical Field
The utility model relates to the technical field of metallurgy, in particular to a steel-making ladle capable of reducing residual molten steel in the ladle.
Background
In the steel mill production process, when the continuous casting, when the molten steel level in the ladle drops to the take the altitude, at first produce rotary motion at the molten steel surface, then the rotational speed accelerates gradually and the liquid level is recessed, until lining up the tap hole, molten steel surface slag blanket receives the influence of internal friction, it is well-wrapped to roll up into along with the swirl, the bale operation worker can misunderstanding that the molten steel has cast finishing in the package this moment, take the closing operation to the ladle tap hole, therefore it is too much to make remaining molten steel in the package, for solving the problem of remaining molten steel in the package, need improve the ladle in the urgent need of the industry.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a steel-making ladle capable of reducing residual molten steel in the ladle, which can reduce the residual molten steel in the ladle during continuous casting.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a steel-making ladle capable of reducing residual molten steel in the ladle is provided with a ladle shell, a fire-resistant layer, a ladle bottom casting fire-resistant layer and a water gap; the ladle is in a conical shape with a large upper part and a small lower part, a refractory layer is arranged around the inner wall of the ladle, and a ladle bottom casting refractory layer is arranged on the surface of the refractory layer at the bottom of the ladle; a water gap is arranged at the bottom of the ladle; and a water gap groove is formed in the upper part of the water gap.
In the steelmaking ladle, the upper edge of the nozzle groove is provided with the nozzle chamfer.
In the steelmaking ladle, the surface of the ladle bottom casting refractory layer is an inclined plane inclined towards the water gap groove; the inclination angle of the inclined plane is 3 degrees.
In the steelmaking ladle, the horizontal section of the water gap groove is circular; the downward vertical depth of the water gap groove from the upper surface of the refractory layer is 250 mm.
Advantageous effects
According to the steel-making ladle, a refractory layer is cast on the basis of the original refractory layer of the ladle bottom, so that a concave surface inclined towards the direction of a water gap is formed on the plane of the ladle bottom; the nozzle is provided with the nozzle groove, when the final stage of casting is performed, as shown in figure 1, molten steel can be collected into the nozzle groove, and when the molten steel is subjected to vortex penetration, the ladle is closed, so that residual molten steel in the ladle is reduced, the yield of casting blanks is further increased, the consumption of iron and steel materials is reduced, and finally the production cost is saved.
Drawings
FIG. 1 is a schematic view of a steelmaking ladle capable of lowering residual molten steel in the ladle;
FIG. 2 is an enlarged partial cross-sectional view of the nozzle;
in the drawings, the reference numerals denote: 1. the method comprises the following steps of steel ladle, 2, a refractory layer, 3, a cladding, 4, a ladle bottom casting refractory layer, 5, molten steel, 6, a nozzle groove, 7, a nozzle chamfer and 8, wherein the refractory layer is arranged on the bottom of the ladle.
Detailed Description
The utility model is further illustrated by the following figures and examples.
According to the steel-making ladle capable of reducing the residual molten steel in the ladle, as shown in figure 1, a ladle nozzle 8 is provided with a nozzle groove 6, and the vertical depth of the nozzle groove is 250 mm. According to theoretical measurement, the larger the radius of the steel ladle when the molten steel 5 penetrates through the steel ladle, the more the residual molten steel in the steel ladle is caused, so that the arrangement of the water gap groove 6 reduces the penetrating radius of the molten steel, and further reduces the residual molten steel.
The steelmaking ladle capable of reducing the residual molten steel in the ladle is characterized in that the bottom of the ladle is provided with a ladle bottom casting fire-resistant layer 4, the ladle bottom casting fire-resistant layer 4 is a fire-resistant layer which is cast on the basis of the original fire-resistant layer, and the surface of the ladle bottom casting fire-resistant layer is concave and is concave towards a water gap groove 6.
According to the utility model, when the steel-making ladle capable of reducing the residual molten steel in the ladle is in the last stage of casting, the molten steel 5 in the ladle flows into the water gap groove 6, the molten steel penetrates through the water gap groove, at the moment, the ladle is closed, and the volume of the residual molten steel is greatly reduced; the operation of closing the ladle is completed by an operator, and the operator closes the valve plate in time according to the penetration condition of the molten steel; the valve plate is located below the nozzle 8 and is not shown.
