Steel ladle slide gate mechanism and steelmaking equipment

Abstract

The invention discloses a steel ladle slide gate mechanism and steelmaking equipment and relates to the field of slide gate mechanisms. The steel ladle slide gate mechanism comprises a wear-resistantlever which is used for keeping an upper sliding plate and a lower sliding plate in close contact in the sliding process. The wear-resistant lever is in sliding contact with the bottom of a sliding car subassembly so that an upward force can be applied to the sliding car subassembly, the lower sliding plate in the sliding car subassembly and the upper sliding plate in a base subassembly are kept in close contact in the moving process, and the surface pressure between the plates is stable, so that the flow control accuracy of molten steel is improved, the occurrence of faults of a slide gate device and the need of shutdown and maintenance are avoided or reduced, and the production cost is lowered and saved; on the other hand, the steel ladle slide gate mechanism further comprises spring adjusting pieces for adjusting springs, and the pressure of the springs in spring boxes to the sliding car subassembly can be adjusted, so that the service life of the device is prolonged, and the production cost is reduced and saved.

Description

technical field [0001] The invention relates to the field of sliding nozzle mechanisms, in particular to a ladle sliding nozzle mechanism and steelmaking equipment. Background technique [0002] The sliding nozzle mechanism is the control device for molten steel in the casting process of the continuous casting machine. It can accurately adjust the water flow from the ladle to the continuous casting tundish, so that the inflow and outflow of molten steel can be balanced, so that the continuous casting operation is easier to control. An indispensable part of smelting. The sliding nozzle mechanism is generally composed of a driving device, a mechanical part and a refractory material (ie, an upper and lower sliding plate, an upper and lower nozzle). [0003] The working principle of the sliding nozzle is to slide the upper and lower sliding bricks through the driving mechanism, thereby driving the opening and closing of the flow nozzle to adjust the flow of molten steel. In or...

AI Technical Summary

Problems solved by technology

[0004] At present, during the sliding process of the upper and lower sliding plates, the surface pressure between the plates is unstable, so that the adjustment of the sliding nozzle may be inaccurate, resulting in problems such as molten steel splashing or unstable flow control.
