Heat preservation tunnel for continuously conveying heat pipes and heat preservation control method

Abstract

The invention relates to the technical field of hot rolling, and discloses a heat preservation tunnel for continuously conveying heat pipes. The heat preservation tunnel comprises a base, a heat preservation tunnel body is fixedly mounted on the upper surface of the base, an outer supporting seat located on the left side of the heat preservation tunnel body is fixedly mounted on the upper surfaceof the base, a control panel located on the right side of the heat preservation tunnel body is fixedly mounted on the upper surface of the base, a driving motor is fixedly installed on the lower surface of the base, a thermocouple is fixedly installed on one side in the heat preservation tunnel body, inner supports are fixedly installed on two sides in the heat preservation tunnel body, a top cover is fixedly installed on the top of the heat preservation tunnel body, an inner-layer steel plate is arranged on the innermost side of the heat preservation tunnel body, a heating layer is arranged on the outer side of the inner-layer steel plate, the outer layer of the heating layer is wrapped by a flame-retardant layer, the heating layer is filled with electric heating wires, and the flame-retardant layer is wrapped by a heat preservation layer. With the technical scheme, the problems of high heat dissipation efficiency of some alloy metals and low requirements of each process on the temperature range are solved.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to a thermal insulation tunnel for continuously transporting heat pipes and a method for controlling thermal insulation. Background technique [0002] The roller table is a transportation device that uses the rotation of cylindrical rollers to convey the rolled piece. It connects the various processes of the rolling production process with each other. Realize operation mechanization, greatly improve working conditions, increase production efficiency, and provide conditions for realizing automatic operation. The weight of the roller table in the rolling workshop accounts for about 40-60% of the weight of the equipment in the workshop. Many roller tables are used in hot strip rolling mills, which are divided into several sections, and each section of the roller table conveys the rolling stock either independently or synchronously with the speed and direction of the rolls. In or...

AI Technical Summary

Problems solved by technology

Transferred on the traditional roller table, it is impossible to control the heat loss, and it cannot meet the temperature requirements of the next process, so that the rolled seamless pipe cannot meet its performance requirements.
