Description

A ladle for controlling steel tapping temperature

Technical Field

The utility model relates to the technical field of steel ladles, in particular to a steel ladle for controlling the temperature of steel tapping.

Background Art

Ladle is a widely used equipment in the steel smelting industry. It is mainly used in steel mills and foundries to receive molten steel, refine and process molten steel and molten iron, and perform pouring. It has a long service life and can withstand high temperatures for a long time. The ladle is used for high-temperature processing of steel products, but different steel products require different temperatures during the casting process. Therefore, the temperature in the ladle needs to be controlled during the casting process to improve the efficiency of steel product casting.

The existing Chinese utility model patent with reference announcement number: CN212019371U discloses a ladle. The utility model includes a vortex-blocking beam fixedly arranged in the ladle, the vortex-blocking beam is located above the water inlet and can divide the axis of the water inlet into an upper and lower part, the vortex-blocking beam is located between the bottom of the ladle and the vortex swirl height, and the bottom position of the ladle near the water inlet is partially lowered by tilting the inner side of the bottom of the ladle and arranging a sinking platform at the bottom, and a through water inlet is arranged on the sinking platform, so that the bottom position of the ladle near the water inlet is partially lowered, and the critical height of the vortex swirl is partially hidden in the lowered part. When the molten steel is at the vortex swirl height, the residual amount of molten steel in the ladle is reduced. By arranging a vortex-blocking beam that can cut off the axis of the water inlet above the water inlet and arranging the vortex-blocking beam between the bottom of the ladle and the swirl height, the vortex-blocking beam can achieve the effect of cutting the vortex axis. The formation of the vortex is suppressed by the combined effect of the local lowering of the bottom position of the ladle near the water inlet and the destruction of the vortex center by the vortex-blocking beam.

When the above-mentioned ladle is used in conjunction with the converter, it is not convenient to control the temperature inside the ladle, which makes it inconvenient to process and use steel products with different temperature requirements, affects the steel product tapping temperature, and reduces the functionality of the ladle. If the ladle temperature is not controlled, it is easy to cause waste of refractory materials, thereby affecting the service life of the ladle and reducing the quality of the ladle.
