Heating furnace burner block replacing method capable of reserving furnace top

Abstract

The invention discloses a heating furnace burner block replacing method capable of reserving a furnace top. The method comprises the following steps that old furnace walls and old burner blocks are disassembled; a carrier loader and hoisting equipment are arranged in a heating furnace, a slide which is led to the inner portion of the heating furnace from the outer portion of the heating furnace is arranged at the head of the heating furnace or the tail of the heating furnace; the carrier loader is made to move to the tail end of the part, located in the heating furnace, of the slide, burner blocks are conveyed onto the part, located outside the heating furnace, of the slide in a hoisting mode through a traveling crane, and after the burner blocks slide onto the carrier loader through the slide, the burner blocks are conveyed by the carrier loader to the bottom of a furnace shell located at the installation position; the hoisting equipment hoists the burner blocks to the installation heights and enables the burner blocks to be installed onto a heat storage tank; formwork erecting, casting and maintenance of furnace wall casting materials are conducted. The method is simple and convenient to achieve, easy to implement, and capable replacing the burner blocks under the condition that the furnace top is reserved. Thus, refractory materials of the furnace top and the structure of the furnace top are protected, the construction period is greatly shortened and the heating furnace burner block replacing method has important practical value for various heating furnaces with burner blocks.

Description

technical field [0001] The invention relates to a method for replacing a burner brick of a heating furnace, in particular to a method for replacing a burner brick of a heating furnace with a furnace top reserved. Background technique [0002] Heating furnace is a kind of thermal equipment used to heat blanks such as billets or continuous casting billets to the temperature required for hot rolling, and is widely used in industrial production. [0003] Such as figure 1 As shown, the heating furnace mostly adopts the combustion-heat storage method in which the heat storage box is installed on the outside of the furnace wall, and the burner brick is installed on the inside to form a nozzle in the furnace wall. The burner brick of the heating furnace and the furnace wall where it is located work in a high-temperature environment for a long time, and need to directly withstand the temperature as high as 1200 ° C, and will withstand vibration and air erosion during the production ...

Problems solved by technology

However, under the same working conditions, the furnace top refractory material is generally less damaged than the furnace wall refractory material and burner bricks, and can be retained and continued to be used. Therefore, the traditional construction method will make the furnace roof refractory material Disturbance will adversely affect its integrity; moreover, the process of dismantling and restoring furnace roof refractory materials and furnace roof hanging steel structures is very complicated, and the required construction period is long, which easily delays normal production
