Abstract

The invention discloses a steel pipe annealing heat treatment system, which comprises an electric furnace and a water tank, wherein the electric furnace comprises a furnace body and an electric heating device arranged in the furnace body. The system is characterized in that the furnace body is obtained by butting and buckling left and right furnace bodies with semicircular outer sections, wherein the two ends of the furnace body are in a closed state after the furnace body is buckled; a furnace body opening and closing control device is arranged outside the furnace body; the water tank is arranged under the furnace body. The system has the advantages of convenience in operation, high speed, high efficiency and capability of shortening heat treatment transfer time and improving heat treatment effects, treatment effects are ensured, and the quality of a product is improved.

Description

technical field [0001] The invention relates to a steel pipe heat treatment equipment, in particular to a steel pipe annealing heat treatment system. Background technique [0002] In the process of cold rolling production of special steel pipes, it is necessary to anneal the rolled pipes frequently to eliminate the chilling stress during cold rolling, so that the next process can be carried out smoothly. A floor-standing electric furnace is used for annealing treatment. First, place the pipe fittings on the trolley, then open the electric furnace door and push the trolley into the electric furnace. Then heat the pipe in the electric furnace to the temperature required for solid solution, and then open the furnace door and pull it out of the table. The pipes on the car are then hoisted together with the pipes and racks placed on the trolley material rack by driving and put into the pool for cooling. [0003] In this existing method, because the traveling speed of the trolley...
