Abstract

The invention provides a furnace cover for a production furnace, which is characterized by comprising a supporting beam, a hoisting and fastening ring frame, T-shaped metal bolts and at least one refractory brick layer, wherein the hoisting and fastening ring frame is arranged below the supporting beam and is connected with the supporting beam; the T-shaped metal bolts comprise horizontal bolts and vertical bolts, and the vertical bolts of the T-shaped metal bolts are hoisted and fastened on the hoisting and fastening ring frame; the at least one refractory brick layer consists of a plurality of refractory bricks, and is hung on the hoisting and fastening ring frame through the plurality of T-shaped metal bolts; each refractory brick layer comprises two adjacent refractory bricks fixedly connected through one T-shaped metal bolt; each refractory brick is provided with an insertion silt; and the horizontal bolt of one T-shaped metal bolt is respectively inserted into the corresponding insertion silts of the two adjacent refractory bricks. The furnace cover has the advantages of safe use, high-temperature resistance, simple structure and simple and convenient maintenance.

Description

technical field [0001] The present invention relates to the field of heating furnaces, and more particularly, to a furnace cover of a production furnace. Background technique [0002] The furnace cover of the graphitization furnace can effectively prevent the heat loss in the furnace, improve the thermal energy utilization rate of the graphitization furnace, and reduce the environmental pollution caused by the graphitization production. [0003] At present, the furnace cover of the graphitization furnace is cast and formed on-site with unshaped materials, using high-temperature refractory castables with phosphoric acid as a binder, and a steel skeleton is used during pouring, and the entire furnace cover structure is supported by the steel skeleton. There are many problems with this furnace cover: [0004] 1. The poured furnace cover is an integral structure, cannot be disassembled, and weighs 3-5 tons. It is extremely inconvenient to install and maintain, and the maintenan...
