Abstract

The invention relates to the field of hot rolling, in particular to a heat preservation tunnel of a continuous delivery hot pipe and a heat preservation control method. The heat preservation tunnel comprises a base, a motor, a conveying roller and a heat preservation tunnel framework. The heat preservation tunnel framework is composed of an upper cover, steel plates on the two sides, fireproof cotton, refractory castable and an electric heating device. The upper cover is located at the upper ends of the steel plates on the two sides, so that an n-shaped framework is formed, a cavity of the framework is filled with the fireproof cotton, the electric heating device is arranged on the inner side of the fireproof cotton, and the inner side and the outer side of the framework are coated with the refractory castable. The heat preservation tunnel is additionally arranged on a traditional roller bed and is composed of the upper cover, the steel plates, the fireproof cotton, the refractory castable and the electric heating device, an electric resistance wire is hung on the refractory castable on the innermost layer of the tunnel so that the electric heating device can be formed, in this way, the heat preservation effect can be achieved, accurate temperature control can also be achieved, the rolling process is ensured, and the yield is improved; and through the partition wall type sectional heating mode, the heating speed of the tunnel 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 for continuously conveying heat pipes and a method for controlling thermal insulation. 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 traditiona...
