Fast disassembling and replacing construction method for water beams of step-type heating furnace

Abstract

The invention relates to the field of construction and repair of furnace linings, in particular to a fast disassembling and replacing construction method for water beams of a step-type heating furnace. The fast disassembling and replacing construction method for the water beams of the step-type heating furnace is characterized in that two groups of water beams (21) which are arranged in parallel are arranged in a step-type heating furnace body, the two groups of water beams comprise a group of long water beams and a group of short water beams, and all the water beams (21) are horizontally erected on water beam stand columns (22); and a sealing box is further arranged in the step-type heating furnace body, and the two opposite sides of the step-type heating furnace body are a rolling mill side and an operation side respectively. The method is characterized by comprising the following steps that 1, holes are formed; 2, supporting parts are manufactured; 3, hanging is carried out; 4, hoisting is carried out; 5, transferring is carried out; 6, the stand columns are disassembled; 7, the water beams are replaced; 8, cleaning is carried out; and 9, repairing is carried out. The construction method has the advantages of being convenient to operate, short in time consumption, high in production efficiency and high in environmental adaptability.

Description

technical field [0001] The invention relates to the field of furnace lining construction and repair, in particular to a construction method for quickly removing and replacing water beams of a walking heating furnace. Background technique [0002] After a long period of use of the walking heating furnace, the inside of the water beam and the water beam column have been washed by water for a long time to cause corrosion, so that the size of the pipe wall is gradually reduced, which will not meet the design requirements, or due to the redesign of the heating furnace, the adoption of a new process, All water beams and water beam columns in the furnace need to be removed and replaced without damaging the furnace top refractory material and minimizing damage to the side wall and furnace bottom refractory material to solve the problems of low utilization rate of the heating furnace and aging equipment. But at present, dismantling the water beam is still a time-consuming and ineffic...

AI Technical Summary

Problems solved by technology

[0002] After a long period of use of the walking heating furnace, the interior of the water beam and the water beam column has been washed by water for a long time to cause corrosion, making the pipe wall size gradually reduced, which will not meet the design requirements, or due to the redesign of the heating furnace and the adoption of new technology, It is necessary to remove and replace all the water beams and water beam columns in the furnace without damaging the furnace top refractory material and minimizing damage to the side wall and furnace bottom refractory material, so as to solve the problems of low utilization rate of the heating furnace and aging equipment status

But at present, dismantling the water beam is still a time-consuming and inefficient operation, which limits the continuous utilization of the walk-in furnace
