Description

Technical Field

[0001] This utility model relates to the technical field of flash furnace maintenance devices, specifically to a flexible binding type flash furnace body local reinforcement device. Background Technology

[0002] In the metallurgical industry, flash furnaces are commonly used high-temperature metallurgical equipment for the rapid melting of powdered concentrates or other metallic raw materials. A flash furnace typically includes a reaction tower, a key component of the furnace body, which contains and facilitates the rapid melting and reaction of the raw materials. Because flash furnaces withstand extremely high temperatures and pressures during operation, the reaction tower and the surrounding furnace structure experience severe thermal and mechanical stresses. Therefore, the frame of a flash furnace is usually an elastic frame capable of adjusting to the stress expansion of the furnace body. This elastic frame structure mainly consists of truncated conical spiral springs and tie rods around the furnace body. During flash furnace maintenance, partial dismantling of the furnace body may be involved. This alters the stress on the entire elastic frame, potentially causing displacement of the truncated conical spiral springs, loss of external restraint, and ultimately, furnace collapse, compromising the safe operation of the furnace.
