Cooling device of pneumatic springs of side-mounted continuous casting molten steel valve

Abstract

The invention relates to a cooling device of pneumatic springs of a side-mounted continuous casting molten steel valve, belonging to a conticaster. The cooling device of a side-mounted continuous casting molten steel valve is characterized in that spring slots, pneumatic springs, spring boxes and clamping devices of the pneumatic springs are respectively and symmetrically arranged at the left outer side and the right outer side of a sliding frame, rectangular horizontal top plates in the fore-and-after direction are respectively welded at the upper part of the left outer lateral wall and the upper part of the right outer lateral wall of the sliding frame, a vertical plate is welded at the bottom of the left end section or the right end section of the horizontal top plate; the left lateralwall and the right lateral wall of the sliding frame, the horizontal top plate and the vertical plate form a spring slot; the inversely mounted pneumatic springs are evenly distributed in the spring slot from front to back, a spring box is mounted in the spring slot from bottom to top, the pneumatic springs are correspondingly arranged in step holes of the spring box, and the clamping devices of the pneumatic springs are respectively mounted corresponding to the outwards extending parts of the front shaft end and the rear shaft end of the spring box on the bottom of a mounting plate. The pneumatic springs are thermally shielded by the slide blocks, the sliding frame and the spring box and provided with air ducts for cooling the pneumatic springs, therefore, good cooling effect and long service life can be obtained.

Description

technical field [0001] The invention belongs to continuous casting machines, in particular to a cooling device for continuous casting molten steel valves. Background technique [0002] At present, the gas springs for molten steel valves used in continuous casting in some domestic iron and steel enterprises are generally installed directly on the slider body at the lower part of the casting port to push the movable skateboard and maintain the close contact between the movable skateboard and the fixed skateboard. The tube introduces high-pressure air to cool the air springs to protect the air springs. In this way, the air springs are cooled. First, the air springs are directly installed on the slider body and are affected by high temperature, which is not easy to cool down, which often leads to The gas spring is overheated for a long time, which greatly shortens the service life of the gas spring and increases the production cost. Once the gas spring is damaged, if it cannot b...

[0002] At present, the gas springs for molten steel valves used in continuous casting in some domestic iron and steel enterprises are generally installed directly on the slider body at the lower part of the casting port to push the movable slide plate and keep the close contact between the movable slide plate and the fixed slide plate. The tube introduces high-pressure air to cool the air springs to protect the air springs. In this way, the air springs are cooled. First, the air springs are directly installed on the slider body and are affected by high temperature, which is not easy to cool down, which often leads to The gas spring is overheated for a long time, which greatly shortens the service life of the gas spring and increases the production cost. Once the gas spring is damaged, if it cannot be replaced in time, it will cause serious steel leakage accidents and cause immeasurable losses to the enterprise. Therefore, the invention A side-mounted gas spring cooling device, which overcomes the shortcomings of the original spring cooling, such as poor ventilation, poor cooling effect, easy damage to the gas spring, large accident hazards, and high consumption costs.
