Rapid cooling method for precision heat treatment steel belt

Abstract

The invention discloses a rapid cooling method for a precision heat treatment steel belt. A cooling bin, an injection pipe, a guide-out piece, a connecting pipe, the steel belt, a drainage pipe, an upper guide roller, a lower guide roller and an auxiliary device are included. The auxiliary device is arranged at the lower end in the cooling bin, the attaching assembly is arranged in the auxiliary device, the attaching assembly is divided into an upper net plate and a lower net plate, a steel belt can directly penetrate through the net plates, the net plates are attached to the upper face and the lower face of the steel belt under the action of the centering mechanism, and then the centering mechanism is driven by the pushing mechanism to make the net plates reciprocate. Heat passing through the surface of the steel belt can be quickly conducted out, the automation effect is good, and the working efficiency is effectively improved; the adjusting mechanism is arranged at the top of the upper screen plate, the upper end of the adjusting mechanism is connected with the shifting and sweeping plate, the shifting and sweeping plate can reciprocate along with the screen plate, the adjusting mechanism can adjust the shifting and sweeping plate to be aligned with the water surface, dross is uniformly scraped and swept to the right end while cooling liquid is shifted, the automation effect is good, and functionality is high.

Description

technical field [0001] The invention relates to the field of precision heat treatment steel strip processing, in particular to a rapid cooling method for precision heat treatment steel strips. Background technique [0002] Steel is easy to rust in air and water, and the corrosion rate of zinc in the atmosphere is only 1 / 15 of the corrosion rate of steel in the atmosphere. During the production and processing of the steel strip, it needs to be treated with heat treatment equipment. After the treatment, it needs to be efficiently cooled with special cooling equipment. [0003] In the cooling process of the existing precision heat-treated steel strip, since the steel strip is in a static state when it enters the cooling bin, the heat conduction efficiency is reduced, and the heating rate of the cooling liquid is fast, resulting in low subsequent cooling efficiency and effect. SUMMARY OF THE INVENTION [0004] Therefore, in order to solve the above deficiencies, the present i...
