Steel plate processing system

Abstract

The invention discloses a steel plate processing system. A heating device comprises a heating shell, wherein the heating shell is closed by a hinged door at the front end, the interior of the heatingshell is divided into an upper heating space and a lower heating space by a partition plate, at least two fixed supporting rods and at least two electric telescopic rods are fixedly connected to the bottom wall of each of the upper heating space and the lower heating space, the upper end of each fixed supporting rod is fixedly connected with a main supporting plate, the upper end of each electrictelescopic rod is fixedly connected with an auxiliary supporting plate, a first infrared temperature detector and a second infrared temperature detector are fixed to the inner wall of the heating shell and the lower end of the partition plate respectively, heat insulation spaces communicating with one another are formed in the left side wall, the right side wall, the upper side wall, the lower side wall and the rear side wall of the heating shell in a hollow mode correspondingly, a circulating fan is fixed to the upper end of the heating shell, an outlet pipe of the circulating fan communicates with a first electric heater, an air outlet pipe of the first electric heater directly communicates with the interior of the upper heating space, the side of the upper heating space communicates with a middle air pipe, and the middle air pipe communicates with a second electric heater.

Description

technical field [0001] The invention relates to the technical field of steel plate processing, in particular to a steel plate processing system. Background technique [0002] Differential speed rolling is asynchronous rolling. Asynchronous rolling is a kind of rolling with unequal speed. The surface speed of the upper and lower work rolls is different to reduce the rolling force. Therefore, it is also called differential rolling, also known as rub rolling. , the asynchronous rolling is used to roll the bimetallic plate, which will cause the bending change of the rolled piece, the asynchronous rolling can adjust the bending curvature of the bimetallic plate, and under the same asynchronous ratio, the thickness ratio of the two metal components is at a certain Under the condition of a certain degree of deformation, a straight rolled piece can be obtained, and the rolling phenomenon of asymmetrical speed has existed in the history of rolling production, and it can be seen every...

Problems solved by technology

[0007] 1. By setting the heat insulation space, the heated exhaust air is sent into the heat insulation space, and a medium temperature layer is formed around the heating shell, which reduces the heat exchange between the heating shell and the external environment during the heating process of the steel plate, and improves the heat output. Utilization rate; and the setting of the auxiliary support plate can make the steel plate have no heating dead angle, which solves the problem of difficult heating at the contact between the steel plate and the main support plate in the past;
