Description

Production equipment of ventilation plug

Technical Field

The utility model relates to the technical field of refractory products for steelmaking, in particular to production equipment of a ventilation plug.

Background

Continuous casting is the abbreviation of Continuous casting steel (Continuous STEEL CASTING). In the process of producing various steel products in steel mills, two methods of solidification molding using molten steel are used, namely a traditional die casting method and a continuous casting method. And the continuous casting technology in the fifties of the twentieth century appears in European and American countries is an advanced technology for directly casting molten steel.

Compared with the traditional method, the continuous casting technology has the remarkable advantages of greatly improving the metal yield and the casting blank quality, saving energy and the like. The continuous casting process is to convey the ladle filled with refined molten steel to a rotary table, and after the rotary table rotates to a pouring position, the molten steel is poured into a tundish, and the tundish distributes the molten steel into each crystallizer through a water gap. The mold is one of the core devices of the continuous casting machine, which shapes the casting and rapidly solidifies and crystallizes. The withdrawal and straightening machine and the crystallization vibration device work together to withdraw the casting in the crystallizer, and after cooling and electromagnetic stirring, the casting is cut into slabs with a certain length, and the stopper rod plays a role of a valve in the process.

The stopper rod is generally formed by compounding different materials, and can be divided into a rod head and a rod body according to different service environments and functions, and the ventilation stopper is arranged in the rod head. The traditional production method of the ventilation plug is to put a die cavity on a base, add materials into the die cavity, put a pressing head and manually knock the pressing head by tools such as a hammer to form. However, the conventional method is used for producing the air-permeable plugs, and because the air-permeable plugs are formed by manual knocking, the quantity of products obtained each time is not large, and the air-permeable plugs produced in different batches have different body densities and appearance sizes, so that quality fluctuation can occur. Moreover, the traditional production method needs to manually take out and demould the breathable plug finished product from the cavity, and has low efficiency and high labor cost.

Therefore, how to effectively improve the production efficiency and the quality stability of the ventilation plug in the integral stopper rod head for the continuous casting tundish and reduce the labor cost are problems to be solved by the technicians in the field.
