Abstract

The invention relates to the field of hot rolling, in particular to a heat preservation tunnel for continuously transporting heat pipes, and a heat preservation control method. The heat preservation tunnel comprises a base, a motor, a transportation roller and a heat preservation tunnel frame, wherein the heat preservation tunnel frame comprises an upper cover, steel plates on the two sides, fireproof cotton, a fireproof castable and an electric heating device; the upper cover is positioned at the upper ends of the steel plates on the two sides to form an n-shaped frame; a cavity of the frame is filled with the fireproof cotton; the electric heating device is arranged on the inner side of the fireproof cotton; and the fireproof castable is smeared on the inner and outer sides of the frame. According to the heat preservation tunnel, from the point of device, the heat preservation tunnel is added on the basis of a traditional roller bed, the heat preservation tunnel frame comprises the upper cover, the steel plates, the fireproof cotton, the fireproof castable and the electric heating device, and resistance wires are hung on the fireproof castable at the innermost layer of the tunnel to form the electric heating device, so that a heat preservation function can be achieved, the temperature can be accurately controlled, the rolling technology is guaranteed, and the finished product rate is increased; and diaphragm-type sectional heating is adopted, so that the tunnel temperature rising speed can be effectively increased, and the temperature control accuracy is improved.

Description

technical field [0001] The invention relates to the field of hot rolling, in particular to a thermal insulation tunnel and a thermal insulation control method. Background technique [0002] The roller table is an important equipment for conveying seamless pipes in the production process of seamless pipes, and plays the role of conveying seamless pipes between various processes. In the production process of traditional seamless pipes, because the temperature of ordinary steel grades does not dissipate quickly and the temperature range required by the process is not strict, there are no protection and heat preservation measures on the conveyor roller table. [0003] In the process of rolling some alloy metals, due to the high heat dissipation efficiency of some alloy metals, and the requirements for the temperature range of each process are very small. It is impossible to control the heat loss when it is conveyed on the traditional roller table, so it cannot meet the temperat...
