Problems solved by technology

The current side drive form makes the connecting rod a swing up and down during the movement of the hydraulic cylinder. This up and down swing will affect the use of the mechanism and affect the stability of the refractory surface pressure in the mechanism. , affecting the service life of refractory materials, the cost will increase, and there will be a certain risk of steel breakout

Abstract

The invention provides a driving device of a steel ladle sliding nozzle mechanism. According to the driving device, vertical swinging of a connecting rod is avoided. The driving device comprises a support fixed to a steel ladle. The support is of a U-shaped structure. A plurality of rotating shafts are arranged at the bottom of the support. A shaft sleeve is arranged between the rotating shafts and the support. A chain wheel is hinged to the middle of the support through a pin shaft. An air cylinder is connected to the chain wheel and rotatably installed on the steel ladle. A chain groove is formed above the rotating shafts. A chain is arranged at the lower portion of the chain groove. A plurality of roller shafts are arranged at the upper portion of the chain groove. Rollers are arranged on the roller shafts. The chain wheel penetrates through the rollers to be matched with the chain. A connecting rod is fixed to one end of the chain groove. The free end of the connecting rod is connected with the sliding nozzle mechanism.

Description

technical field [0001] The invention relates to a sliding nozzle device, in particular to a driving device for a ladle sliding nozzle mechanism. Background technique [0002] At present, there are two ways of driving the transmission hydraulic cylinder of the sliding nozzle mechanism used on the steelmaking ladle in China, one is a straight-forward type, and the hydraulic cylinder is installed above the mechanism. The other is the side drive type, and the hydraulic cylinder is installed on the wall of the ladle. Such as figure 1 shown. The current side drive form makes the connecting rod a swing up and down during the movement of the hydraulic cylinder. This up and down swing will affect the use of the mechanism and affect the stability of the refractory surface pressure in the mechanism. , affecting the service life of refractory materials, the cost will increase, and there will be a certain risk of steel breakout. Contents of the invention [0003] The invention prov...
