Embedded installation method for heating furnace top energy-saving thermal radiation body

Abstract

The invention relates to an embedded installation method for a heating furnace top energy-saving thermal radiation body and belongs to the technical field of metallurgical industry steel rolling heating furnaces. According to the technical scheme, the embedded installation method comprises the following steps that firstly, the installation end of the thermal radiation body (1) is embedded into a furnace top refractory material; secondly, a pouring template (5) is laid on a furnace top; thirdly, filler (4) with a certain thickness is laid on the pouring template (5), and the radiation end of the thermal radiation body (1) is located in the filler (4); fourthly, a pouring material (2) is used for pouring the furnace top, and therefore the installation end of the thermal radiation body (1) and the furnace top can be poured into a whole; and fifthly, after the furnace top is poured, the pouring template (5) on the furnace top and the filler (4) are demounted, and the radiation end of the thermal radiation body (1) can he exposed out. The embedded installation method has the beneficial effects that it is ensured that the thermal radiation body cannot disengage, the repairing amount andthe maintenance cost of the thermal radiation body are reduced, and the energy-saving effect of the thermal radiation body is improved.

Description

technical field [0001] The invention relates to an embedded installation method of an energy-saving heat radiation body on the top of a heating furnace, and belongs to the technical field of steel rolling heating furnaces in the metallurgical industry. Background technique [0002] In metallurgical enterprises, the steel rolling heating furnace is used to heat the steel billet. The heating furnace mainly uses radiation heat transfer, including the direct radiation heat transfer of the flame to the steel billet when the burner burns, and the indirect radiation heat transfer of the high temperature furnace lining to the steel billet. Among them, the high temperature furnace lining The heat transfer of the billet accounts for more than 50% of the total heat transfer. By increasing the surface area of ​​the furnace lining and restricting the radiation emission direction, it is an important way to enhance the radiation heat transfer efficiency in the furnace, which can effectively...

Problems solved by technology

This method requires slotting in the furnace lining, which affects the overall performance of the furnace lining. At the same time, it has high requirements on the particle size and construction quality of the refractory material of the heating furnace. Affects the installation of heat radiators

[0007] Patent No. 201711085249.7 also discloses a buckle-type installation method. A hole is reserved on the furnace roof to install a threaded section to fix the heat radiation body. This method requires holes in the furnace roof, which will affect the life of the furnace roof and affect the refractory material of the heating furnace. The particle size and construction quality requirements are relatively high, which will easily affect the installation quality of the heat radiator

[0008] In addition, the installation method of the above-mentioned energy-saving heat radiation body has strict requirements on the material selection of the furnace lining refractory material, the construction quality of the furnace lining, and the holes and trapezoidal grooves reserved for the furnace lining, etc., but the construction accuracy of the steel rolling heating furnace lining is difficult to meet The requirements of the above installation methods will ultimately affect the promotion of energy-saving technology for heat radiators
