Problems solved by technology

[0004] However, due to the production of the steel strip, after the liquid in the water tank is initially cooled with one end of the steel strip, the temperature of the liquid rises, and the liquid cannot flow in time, resulting in that the temperature at the end of the steel strip is inconsistent with the initial liquid temperature. Quenching forms a certain temperature difference, which affects the quenching effect of the steel strip, and the liquid flow is uneven, and the mixing of cold liquid and hot liquid will also lead to a large temperature difference and uneven heating temperature of the quenching part of the steel strip

Abstract

The invention provides a hydraulic-plate-free quenching device and method for continuous quenching of a steel strip. The hydraulic-plate-free quenching device comprises an outer box and a drainage box. The top of the outer box is fixedly connected with the drainage box, the top of the interior of the outer box is fixedly connected with a water guide assembly which can discharge cold liquid, and the interior of the outer box is rotationally connected with a rotating assembly which can rotate water flow to conduct heat exchange. According to the hydraulic-plate-free quenching device and method, the cold liquid flows in the outer box and makes contact with a high-temperature iron sheet, the temperature of the cold liquid can be increased, after the temperature of the cold liquid is increased, the liquid level can be increased through thermal expansion and cold contraction in the device, the liquid can rise to the drainage box, the liquid is rapidly discharged through the water guide assembly, a water guide device of the water guide assembly discharges the liquid in time, flowing of the liquid is accelerated, and the heat can be timely dissipated; and water flow in the outer box can be rapidly exchanged through the rotating assembly, the temperature of the surface of the steel strip can be rapidly circulated, the temperature of the surface of the steel strip can be uniformly exchanged, the heat exchange area of the steel strip and the flowing area of water are increased, and the quenched part of the steel strip can be uniform.

Description

technical field [0001] The invention relates to the field of continuous quenching of steel strips, in particular to a non-hydraulic plate quenching device and method for continuous quenching of steel strips. Background technique [0002] The continuous quenching of the steel strip is to quench the surface of the steel strip. It is to spray water to cool the surface of the steel strip immediately after the temperature rises, so that the surface of the steel strip can obtain a hardened layer of a certain depth, which can make the surface of the steel strip wear-resistant and torsion-resistant. , Anti-bending fatigue and contact fatigue effects, and when the steel strip is quenched, it is impacted by liquid, and the liquid flow affects the quenching environment, causing a certain impact on the steel strip. [0003] In view of the above-mentioned technical problems in the preparation device for water-in-water coating production, it was found through retrieval that there is a pat...
