Measures on production line for casing pipe

　　In order to maintain a heat-treated product with stable performance during the rapid heat treatment of induction heating, the following measures should be taken on the production line:

　　(1) The casing pipe plant uses continuous heating steel bridging technology to apply bridging technology to improve the phenomenon of low steel temperature and increase the steel product yield. The use of computers to control the head and tail of steel technology; the use of dual-frequency power to control the temperature of the end of the steel pipe; the use of rotating joints to achieve a great advance, etc. to improve the longitudinal temperature uniformity of the steel.

　　(2) Advanced steel conveyors are used to ensure uniform steel speeds, and steel tubes and large-size bars should rotate at a constant speed. The transmission mechanism should use variable frequency drive to improve the stability and reliability of the mechanism. This is one of the important conditions for assuring that the longitudinal temperature of the phased material is uniform during rapid heating.

　　(3) The use of advanced and reliable heating temperature control system temperature and power closed-loop home-made system is currently the best temperature control system. The control content of the oil casing manufacturer includes elements related to heating temperature such as power and steel speed, which can accurately control the level reached by the heating temperature.
