Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of refractory products for steelmaking, more particularly to a production equipment of a gas-permeable plug. BACKGROUND

[0002] Continuous casting is the abbreviation of continuous steel casting. In the production of various steel products in the steel plant, there are two methods for using molten steel to solidify and form: traditional mold casting method and continuous casting method. The continuous casting technology appeared in Europe and the United States in the 1950s is an advanced technology for directly pouring molten steel into shape.

[0003] Compared with the traditional method, the continuous casting technology has the advantages of greatly improving the metal yield and the quality of the casting blank, saving energy, etc. The continuous casting process is to transport the ladle containing refined molten steel to the rotating table, rotate the rotating table to the pouring position, pour the molten steel into the tundish, and then distribute the molten steel from the tundish to each crystallizer through the nozzle. The crystallizer is one of the core equipment of the continuous casting machine, which makes the casting shape and quickly solidifies and crystallizes. The drawing and straightening machine and the crystallization vibration device jointly act on the casting in the crystallizer, and after cooling and electromagnetic stirring, the casting is cut into a certain length of slab, and the stopper participates in the process and plays the role of "valve".

[0004] The stopper is generally composed of different materials, and can be divided into a rod head and a rod body according to different service environments and functions, and a gas-permeable plug is in the rod head. The traditional production method of the gas-permeable plug is to place the mold cavity on the base, add the material into the cavity, and manually knock the pressure head with a hammer or other tools to form. However, the production of the gas-permeable plug by the traditional method is manually knocked to form, so that the number of products obtained each time is not much, and the bulk density and appearance size of the gas-permeable plugs produced in different batches are different, which may cause quality fluctuations. Moreover, the traditional production method needs to manually take out the finished gas-permeable plug from the cavity for demolding, which is slow in efficiency and high in labor cost.

[0005] Therefore, how to effectively improve the production efficiency and quality stability of the gas-permeable plug in the rod head of the whole stopper for continuous casting tundish and reduce the labor cost is a problem to be solved by those skilled in the art. Utility model content
