Description

Technical Field

[0001] The utility model relates to the technical field of magnesium-calcium-carbon brick processing, in particular to a tundish water nozzle. Background Art

[0002] Magnesia-calcium carbon brick refers to a refractory product made of dolomite sand, magnesia sand and flaky graphite as the main raw materials. Its main feature is that it is better than magnesia-calcium brick in resistance to corrosion by low-alkalinity and low-iron slag. In the processing of magnesia-calcium carbon bricks, it is necessary to coat the surface of magnesia-calcium bricks to improve their corrosion resistance and wear resistance and extend their service life. The spraying equipment will be equipped with a tundish water inlet, which is used for the middle point of the pipeline and for injecting fluid. It is an important component in pipeline connection, commonly used in hot water circulation systems and other occasions. It can ensure the temperature balance at the pipeline connection and effectively solve the problem of unstable water pressure in the pipeline.

[0003] The structure of a conventional tundish water inlet is relatively simple. When conveying liquid materials, as the use time increases, the surface will cause material accumulation on the inner wall surface due to factors such as deposition and adhesion, thus affecting the normal conveying of the liquid material. At the same time, the structure is relatively inconvenient to disassemble, and special tools need to be used for operation, which is relatively time-consuming and labor-intensive.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a tundish water outlet is proposed. Utility Model Content
