High-temperature flue balancer flashboard

Abstract

The invention aims to disclose a high-temperature flue balancer flashboard which comprises a cross beam, vertical partition plates and a transverse partition plate, the vertical partition plates are vertically welded to the bottom of the cross beam, the transverse partition plate is vertically welded to the vertical partition plates, and the cross beam and the transverse partition plate are connected and fixed through vertically-welded tie bars. A lifting lug is vertically welded to the top of the cross beam, and a high-temperature castable is poured on a frame formed by the cross beam, the vertical partition plates, the transverse partition plates, the tie bars and the lifting lug; compared with the prior art, the metal lacing wire type frame is adopted, the lacing wires with the expansion bends are arranged, and a plurality of scratch nails are welded, so that the strength and the adhesive force of high-temperature castable are greatly improved, the high-temperature castable is not prone to falling off, the flashboard is not prone to being burnt and falling off, the working intensity of operators is reduced, the cost is saved, and the flashboard is convenient and easy to implement and is easy to implement under existing conditions; the purpose of the invention is achieved.

Description

technical field [0001] The invention relates to a balancer gate, in particular to a high-temperature flue balancer gate widely used in the metallurgical industry. Background technique [0002] The main raw material of anode carbon block for aluminum electrolysis - raw petroleum coke needs to be calcined at high temperature with calciner or other equipment. Contains SO 2 , H 2 O and O 2 etc., are acidic oxidizing gases. [0003] Therefore, flue shutters are required to control the exhaust gas in the gas and air regenerators. The gate valve structure originally used in carbon calcination is a reinforced dragon skeleton (such as figure 1 The disadvantage is that this kind of gate cannot resist high temperature for a long time, and the long-term use will cause the steel bar to expand, causing the castable and the dragon skeleton to fall off in layers. Drop, affect production, increase cost. [0004] Therefore, a high-temperature flue equalizer shutter is particularly need...

Problems solved by technology

The gate valve structure originally used for carbon calcination is a reinforced dragon skeleton (such as figure 1 As shown), the disadvantage is that this kind of ram cannot resist high temperature for a long time. Long-term use will cause the steel bar to expand, causing the castable and dragon skeleton to delaminate and fall off. Drop, affect production, increase cost
