Tubing end induction heating equipment

1. The composition of the induction heating device at the end of the tubing

The tubing end induction heating equipment consists of medium frequency induction heating furnace, capacitor cabinet, trolley, hydraulic cylinder, water pack, trolley, stainless steel towline, water and electric oil pipeline and intermediate frequency power cabinet.

This set of equipment has two trolleys, each of which is placed on a rail laid on the ground, driven by human power, and has a positioning screw device. There is a small car on each trolley. The chassis of the trolley is welded by angle steel, and the small wheel is aV -shaped groove wheel to ensure the smooth movement of the trolley. The chassis of the car is equipped with a worm lifter, and a large bottom plate made of an epoxy plate is fixed on the lifter. To ensure the smooth rise and fall of the large floor, the large floor and the car chassis are positioned by linear slide rails. A medium-frequency induction heating furnace is installed at each end of the large bottom plate. The trolley can be moved forward and backward along the track fixed on the trolley under the push of the cylinder. The intermediate frequency induction heating furnace is fixed on the small bottom plate by four bolts. The large bottom plate can be raised or lowered by the manual lifter, and the small bottom plate can pass through the wire. The rod moves left and right to adjust the center of the intermediate frequency induction heating furnace in the working position. Each IF induction furnace is equipped with a capacitor cabinet. The capacitor cabinet is fixed on the trolley, and the capacitor cabinet is connected with the medium frequency induction heating furnace through a water-cooled cable. One end of the water and oil pipeline is connected to the equipment on the trolley, and the other end is connected to the water supply pipe joint in the intermediate frequency power cabinet and the trench. The connection between the capacitor cabinet on the trolley and the intermediate frequency induction heating furnace and the water and oil connection between the trolley and the ground are respectively installed in the stainless steel towline.

2, the structure, function and working principle of the oil pipe end induction heating equipment

, The principle of induction heating of the workpiece is heated by the heat generated in the workpiece itself by electromagnetic induction, this has the heating fast heating, uniform heating, high heating efficiency, and very little oxidation process reproducibility, etc., which The medium frequency induction heating furnace is widely used in the pressure processing of metal materials and the heating process of heat treatment. The medium frequency induction heating furnace is composed of an induction coil, a furnace lining, a supporting fixed structure and a furnace shell. The induction coil is made of a copper tube with a rectangular cross section. The copper tube is cooled by water during operation; the support structure and the furnace shell are made of non-metallic materials with high strength, high temperature resistance and non-flammability.

This equipment total power 180kw and 220kw two kinds of specifications 16 16 station frequency induction furnace to meet different specifications of the ends of the heating pipe. No. 1 No. 1furnace carriage and No. 2 furnace power and 180kw respectively 220kw, No. 2 No. 3furnace carriage and 4 respectively furnace power is 180kw and 220kw. The center distance of the two IF induction furnaces on each trolley is 1200 mm and the center is 1000 mm above the ground . Each of the four furnaces is equipped with its own intermediate frequency power cabinet and capacitor cabinet. The 16 IF induction furnaces have the same dimensions and mounting interfaces to ensure that the IF induction furnace can be replaced quickly . ,
