Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel production and relates to a tool for measuring the immersion depth of a tundish water outlet. Background Art
[0002] The continuous casting machine adopts submerged nozzle protection pouring from the tundish to the crystallizer, which plays the role of isolating the air, avoiding the secondary oxidation of molten steel, improving the quality of the ingot, improving the on-site operating conditions and improving the surface defects of the ingot. It is the intermediate link of continuous casting production quality control. Research has found that the continuous casting adopts the method of submerged nozzle protection pouring, and the depth of the submerged nozzle of the tundish inserted into the molten steel must be strictly controlled. Too deep or too shallow insertion depth will have an adverse effect on the crystallizer process and the melting of the protective slag. Therefore, the insertion depth of the submerged nozzle must be strictly controlled. However, the submerged nozzle is inserted below the liquid level of the high-temperature molten steel in the crystallizer, and the size of the inner cavity of the crystallizer is relatively small. Therefore, the insertion depth of the submerged nozzle is difficult to control through precise measurement and difficult to display intuitively.
[0003] At present, continuous casting workers use wire bending to measure the immersion depth of the tundish outlet. This method has a certain risk of scalding during operation, the measurement accuracy is not high, and the consumption of wire is large. Therefore, a tool is needed that can accurately measure the immersion depth of the tundish outlet and reduce the operation risk. Utility Model Content
