On-line annealing device capable of automatically adjusting temperature of pipe

An on-line annealing device capable of automatically adjusting the temperature of a pipe comprises the pipe, a supporting frame, a heating power source and a control cabinet, a quartz tube is arranged on the supporting frame, the quartz tube is sequentially provided with an induction coil, a temperature measuring gun, a heat preservation section and a graphite sleeve in the movement direction of the pipe, and the induction coil is electrically connected with the heating power source. The temperature measuring gun is electrically connected with the control cabinet; therefore, the problems that an existing online pipe annealing device is low in automation degree and difficult in temperature adjustment are solved, the automatic temperature adjustment function can be achieved, annealing temperature control is intelligent and efficient, the operation difficulty is lowered, the temperature stability is enhanced, and the stability of pipe performance is further improved. 一种管材自动调温在线退火装置，包括管材、支撑架、加热电源、控制柜，所述支撑架上设有石英管，
