Steering structure for molten metal quenching

Abstract

The invention relates to a steering structure for molten metal quenching, which is arranged at an inlet of a molten metal quenching pool, and is structurally characterized by comprising a box body, a rotating shaft mechanism and a lifting mechanism, the rotating shaft mechanism is provided with a rotating shaft, and a body of the rotating shaft is sleeved with a winding drum and is positioned in an inner cavity of the box body; the end part of the rotating shaft is positioned outside the box body and is connected with a rotating driving structure; wear-resistant cloth is wound in the winding drum, and the wear-resistant cloth is wound on the drum to form an extensible roll-shaped structure, so that the wear-resistant cloth at a steering part can be conveniently replaced by driving the rotating shaft to rotate; the lifting mechanism is connected to the bottom face of the rotating shaft mechanism to form a driving structure for ascending or descending of the rotating shaft mechanism. The steering structure has the characteristics and progresses that wear-resistant materials do not need to be frequently replaced, continuous work of a production line is maintained, stable product quality is ensured, stable furnace atmosphere is maintained, and production cost is low.

Description

technical field [0001] The invention relates to a steering structure, in particular to a steering structure for molten metal quenching, which is suitable for equipment in a molten metal quenching pool. It belongs to the technical field of metal heat treatment equipment. [0002] technical background [0003] In the prior art, in the steel strip heat treatment production line of medium and high carbon steel, a steering device needs to be installed at the entrance of the molten metal quenching pool. This steering device is generally composed of a semicircular metal sheet wrapped in wear-resistant cloth. During production and application, the steel belt (workpiece) is in contact with the wear-resistant cloth to avoid scratches on the surface of the workpiece. However, since the wear-resistant cloth is a wearing part, the wear-resistant cloth will wear out after long-term use and needs to be taken out for replacement. Therefore, the prior art steering device has the following p...

Problems solved by technology

[0004] The object of the present invention is to solve the problems that the steering device in the prior art requires frequent replacement of wear-resistant materials, resulting in frequent shutdowns, unstable product quality, unstable furnace atmosphere, and increased production costs. The steering structure at the entrance of the metal quenching pool has outstanding substantive features and significant technological progress such as no need to frequently replace wear-resistant cloth, maintain continuous operation of the production line, ensure stable product quality, maintain stable furnace atmosphere, and low production costs.
