Abstract

The invention discloses a water retaining device between a quenching machine and a quenching furnace and a control method of the water retaining device. The water retaining device comprises a mounting bracket (1), a lifting assembly (2), a baffle (3) and a fire-resistant roller shutter assembly (4), the mounting bracket is mounted at a quenching machine inlet (5); the lifting assembly is installed on the installation support, and the baffle is installed at the lifting end of the lifting assembly and is perpendicular to the running direction of a quenching machine roller way (6). The fireproof roller shutter assembly is installed on the lower edge of the baffle. The control method comprises the following steps: when a quenched steel plate (7) leaves the quenching furnace and enters the quenching machine and the quenching machine begins to spray water for quenching, if the width of the quenched steel plate exceeds a critical width or the thickness exceeds a critical thickness, controlling the lifting assembly to descend the baffle to a preset baffle working height. According to the water retaining device and the control method thereof, sprayed water of the quenching machine can be prevented from splashing into the quenching furnace, and the hearth atmosphere of the quenching furnace is prevented from being damaged.

Description

technical field [0001] The invention relates to a metal heat treatment device and method, in particular to a water retaining device between a quenching machine and a quenching furnace and a control method thereof. Background technique [0002] The quenching process is an important and commonly used process in the steel production process. After the quenching process, the surface of the steel product will form a harder martensitic structure. [0003] Take the steel plate quenching work area on the thick plate production line of an iron and steel company as an example. The thick plate mentioned here refers to the thick steel plate. In the thick plate production process, there is a quenching process. The equipment to realize the quenching process includes quenching Furnace and quenching machine, usually the quenching furnace and the quenching machine are set continuously, that is, the entrance of the quenching machine is followed by the exit of the quenching furnace. Immediate...
