Embodiment Construction

[0023] A method for preventing accidental opening of a ladle sliding mechanism, characterized in that the method includes the following steps:

[0024] a. Before the ladle is baked, remove the hydraulic cylinder from the ladle, install the support and protection rod, tap the steel after smelting, and lift the ladle to the designated position;

[0025] b. Remove the support and protection rod from the ladle, install the hydraulic cylinder, and complete the drainage of the ladle;

[0026] c. Pouring, then remove the hydraulic cylinder from the ladle, install the support and protection rod, and lift it back to the smelting workshop.

[0027] The support and protection rod is cylindrical, with a length of 800-1000 mm and a cross-sectional diameter of 50-60 mm.

[0028] The upper and lower parts of the support protection rod have holes respectively, the upper part is connected with the upper support of the ladle through pins, and the lower part is connected with the lower pull rod...

Abstract

The invention relates to a method for preventing steel ladle slide mechanism from being opened, especially being opened accidentally. The method is characterized in that the method comprises following steps of before a steel ladle is baked, picking off a hydraulic cylinder from the steel ladle, installing supporting handrails, taking out the steel ladle after being smelt and then lifting the steel ladle to an assigned position; dismounting the supporting handrails from the steel ladle, assembling the hydraulic cylinder and finishing drainage of the steel ladle; and pouring the steel ladle, then dismounting the hydraulic cylinder from the steel ladle, assembling the supporting handrails and lifting the steel ladle back to a melting workshop. According to the invention, it can be avoided that a slide mechanism is opened caused by collision of external force during a lifting process of smelting or pouring of a steel ladle carrying molten steel, thereby achieving an objective of safe production.

Description

technical field [0001] The invention relates to a method for preventing the ladle sliding mechanism from opening, in particular to a method for preventing the ladle sliding mechanism from opening accidentally. Background technique [0002] At present, most domestic steel foundries use the method of controlling the closing of the sliding nozzle at the bottom of the ladle when pouring castings. During the pouring process, the sliding nozzle at the bottom of the ladle is pulled open by sliding the hydraulic cylinder on the sliding mechanism. If the hydraulic cylinder is directly attached to the ladle for molten steel smelting, the pressure in the hydraulic cylinder will increase, and it is easy to cause the hydraulic cylinder to fail during pouring. The phenomenon that it cannot be opened or closed is prone to safety accidents. Therefore, during smelting, the hydraulic cylinder is usually taken off from the ladle, and at this time, the original space of the hydraulic cylinder ...
