Description

Ladle nozzle casing device with accurate ranging function

Technical Field

The utility model relates to the installation of a drain opening, in particular to a ladle drain opening casing device with a precise distance measurement function.

Background

The ladle is in a very important position in the metal smelting process, is a metallurgical vessel with highest use frequency, and mainly has the function of receiving molten steel from a converter and an electric furnace, finishing refining processes such as LF, RH and the like through the ladle, and finally placing the molten steel into a tundish through a water gap at the bottom of the ladle for the next continuous casting process. The ladle nozzle brick is generally divided into an upper nozzle and a lower nozzle, the upper nozzle brick is arranged in a nozzle pocket brick at the bottom of the ladle, the lower nozzle brick is arranged in a sliding mechanism outside the ladle, and two sliding plate bricks are clamped between the two nozzle bricks to control the flow rate of molten steel. Because the position of the sewer brick is special, the sewer brick is positioned outside the ladle, the temperature of molten steel can reach about 1600 ℃ during tapping, and the sewer brick is contacted with external cold air after tapping, so that the sewer brick can be subjected to strong thermal shock, the whole structure of the sewer brick is broken, and steel leakage accidents are easy to occur. In order to prevent the bottom nozzle brick from peeling off after fracture, a steel shell is generally sleeved outside the bottom nozzle brick in the production process to protect the structural integrity of the bottom nozzle brick, and fire clay is applied between the steel shell and the bottom nozzle for joint filling and connection. Because the fireclay is relatively sticky, the steel shell has larger resistance in the installation process, and the installation work is generally needed by means of tools or equipment.

In the process of installing the steel shell, the stroke of installing the steel shell is determined according to the operation habit of an operator, and the situation that the steel shell is not installed in place or is excessively installed easily occurs. And when the installation is not in place, the secondary propulsion is needed. When the steel shell is excessively installed, the steel shell needs to be reversely pressed to be retracted to a part, the operation is easy to break the fireclay between the steel shell and the water outlet, and then a cavity phenomenon appears, so that the quality of products is greatly influenced.
