Detection and recovery device for high-temperature alloy bent furnace tube and using method thereof

Abstract

The invention relates to a detection and recovery device for a high-temperature alloy bent furnace tube and a using method thereof. The detection and recovery device comprises a shell, a first cavitywith a leftward opening is formed in the shell, and a cutting and fixing device capable of fixing the furnace tube when the furnace tube is cut is arranged in the first cavity. A second cavity with aforward opening is formed in the position, on the right side of the first cavity, in the shell, and a triangular first through hole penetrating leftwards is formed in the left side face of the secondcavity. The detection and recovery device for the high-temperature alloy bent furnace tube and the using method thereof are simple in structure and capable of cutting the furnace tube, a vertical partof the integrally-bent furnace tube is reserved, and reutilization and transportation are facilitated. During cutting, a cutting part can be cooled, and the influence of the high temperature of the cutting part on welding in the recovery process is reduced. According to the detection and recovery device for the high-temperature alloy bent furnace tube and the using method thereof, the furnace tube can be detected, and the furnace tube with defects on the surface can be marked to ensure the quality of the recovered furnace tube. During cutting, the length of the cut furnace tube can be set, and later reutilization is facilitated.

Description

technical field [0001] The invention relates to the technical field of alloy recovery, in particular to a detection and recovery device for a high-temperature alloy bent furnace tube and a method for using the same. Background technique [0002] With the upgrading of the industry, many coal-fired boilers are gradually being eliminated, but the furnace tubes inside them may not have reached their service life. The furnace tubes of boilers are generally made of high-temperature alloys, which have high cost and high recovery value. At present, The recycling and processing method of high-temperature alloys is generally melting and recasting, but the furnace tube of the boiler may only have a difference at the interface, and remelting and recasting wastes energy and increases energy loss. Contents of the invention [0003] The object of the present invention is to provide a detection and recovery device for a superalloy bent furnace tube and its use method, which are used to ov...

[0002] With the upgrading of the industry, many coal-fired boilers are gradually being eliminated, but the furnace tubes inside them may not have reached their service life. The furnace tubes of boilers are generally made of high-temperature alloys, which have high cost and high recovery value. At present, The recovery and treatment method of high-temperature alloys is generally melting and recasting, but the furnace tube of the boiler may only have a difference at the interface. Remelting and recasting wastes energy and increases energy loss.
