Problems solved by technology
[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a steel plate leveling treatment process, which can be achieved by putting the leveling mechanism into a vacuum annealing furnace, and the gas in the air cavity inside the leveling box increases with the temperature. And expand, so as to exert pressure on the elastic wall on the lower side, and then transmit the force to the steel plate, and finally complete the leveling. The pressure of each part of the steel plate is basically the same, so as to achieve a comprehensive and complete leveling, avoiding the local plastic deformation of the existing leveling machine on the steel plate, preventing the problem of poor leveling effect caused by uneven force, and at the same time Avoid the current low-temperature leveling by rolling to cause local cracks in the steel plate, and the risk of crushing damage, and improve the leveling effect of the steel plate leveling and the qualified rate of the steel plate

Embodiment
[0046] see figure 1 , a steel plate leveling process, comprising the steps of:
[0047] S1, placing the steel plate to be leveled at the leveling position inside the leveling mechanism, and fixing the leveling mechanism;
[0048] S2, fill the air chamber in the leveling mechanism with air of 1.5 standard atmospheric pressure, and then seal the air inlet after the inflation is completed;
[0049] S3, put the entire leveling mechanism into the vacuum annealing furnace, and vacuum the vacuum annealing furnace. The vacuum degree in the vacuum annealing furnace is not lower than 10-2 MPa, and the vacuum degree in the vacuum annealing furnace can ensure the annealing effect To further ensure the plastic deformation and leveling effect of the steel plate, the steel plate to be leveled is annealed, the annealing temperature is 900 °C, and the holding time is 100 minutes;
[0050] S4, after the heat preservation is completed, cool down to room temperature with the vacuum annealing fu...

Abstract
The invention discloses a steel plate leveling treatment process, and belongs to the technical field of steel plate treatment. The steel plate leveling treatment process comprises the following steps that firstly, a leveling bottom plate and a leveling pressing plate can be fixed through a fixing assembly, so that the stability of subsequent leveling of a steel plate is guaranteed; then a leveling mechanism is placed in a vacuum annealing furnace, gas in an air cavity in a leveling box expands along with the temperature rise, so that pressure is applied to an elastic wall on the lower side, then acting force is transmitted to the steel plate, and finally leveling is completed; and due to the uniformity of the gas pressure intensity, the pressures of the elastic wall on various parts of the steel plate are basically consistent, so that comprehensive and complete leveling is achieved, the problem that an existing leveling machine only carries out plastic deformation on the local part of the steel plate is avoided, the problem that the leveling effect is poor due to uneven stress is solved, meanwhile, the risk that the local part of the steel plate is cracked and broken due to low-temperature leveling of the existing leveling machine is avoided, and the leveling effect and the percent of pass of the steel plate are improved.
Description
technical field [0001] The invention relates to the technical field of steel plate processing, and more specifically, relates to a steel plate leveling process. Background technique [0002] Steel plate refers to a flat steel material that is poured with molten steel and pressed after cooling. Steel plates are flat, rectangular and can be rolled directly or cut from wide strips. Steel plates are classified according to their thickness, those less than 4 mm are called thin steel plates, those of 4-60 mm are called medium-thick steel plates, and those of 60-115 mm are called extra-thick steel plates. According to rolling, steel plates can be divided into hot rolling and cold rolling. Sheets are classified by steel type, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron sheets, etc.; by professional use, there are plates for oil drums, Enamel plate...
