1. Xi’anMedium frequency melting furnaceculture
1、Xi'anMedium frequency melting furnacedevelopment Goals
2. Xi’anMedium frequency melting furnaceintroduce:
1、Xi'anMedium frequency melting furnaceopen furnace body
Xi'anMedium frequency melting furnaceThe furnace body mainly includes: open furnace body, furnace frame, furnace cover, tilting furnace cylinder, vacuum hood with furnace cover, hydraulic front and rear tilting cylinder, sensor, yoke, high-pressure carbon-free hose, furnace mouth and furnace bottom Pouring fixing materials, a complete set of stainless steel water inlet distributors, return water collectors and clamps, wall-mounted inlet and outlet water collectors, etc. The cylinder is designed to use flame-retardant hydraulic oil as the hydraulic medium. All hydraulic seals are suitable for use with flame retardant hydraulic oil.
（1）Xi'anMedium frequency melting furnaceThe steel structure of the furnace body adopts an open steel structure. Large-sized square steel or H steel pipes constitute the basic structure of the furnace frame. The overall structure is simple, strong, and easy for daily maintenance and inspection.
（2）Xi'anMedium frequency melting furnaceThe maximum inclination angle of the furnace body is 95 degrees.
（3）Xi'anMedium frequency melting furnaceThe surface of the furnace platform is knotted with refractory materials, which fully protects the furnace body and prevents the furnace platform from deforming.
（4）Xi'anMedium frequency melting furnaceThe upper part is removable for easy replacement of the induction coil.
(5) The heavy-duty steel structure pillars on both sides are the strongest support for the induction furnace body. They provide the axis of hydraulic tilting. At the same time, the outward and upward movement of the axis ensures the movement trajectory of the furnace body's tap hole. Minimum, reducing energy loss during tapping.
（6）Xi'anMedium frequency melting furnaceThe copper tube of the induction coil is made of China Aluminum Copper. The material is solid, durable and highly conductive TU1 oxygen-free copper tube.
（7）The vacuum pressure impregnation paint and high-strength insulating performance material wrapping process is used to solve the problem of insulation sparking during operation, greatly improving the reliability of operation and reducing the cost of downtime maintenance. The A14 material pouring material casting process is used to effectively solve the damage to the coil in the event of a furnace penetration accident, and the mechanical strength and insulation strength of the coil are significantly increased. The multi-channel parallel coil structure is adopted, and the flat winding process is used during winding, which effectively solves the problem of magnetic field balance and loss caused by tape leakage. Due to the reduction of the leakage magnetic field, the electric power of the coil is reduced, which will increase the service life of the furnace lining.
2、Xi'anMedium frequency melting furnaceOne to two power supply parameters:
Xi'anMedium frequency melting furnaceThe one-for-two intermediate frequency furnace is an intermediate frequency power supply with two furnaces working at the same time. The power can be distributed arbitrarily. One is a melting furnace and the other is a holding furnace. The melting is continuous. When necessary, the temperature can be raised at the correct temperature. Heating and tempering can improve production efficiency and ensure normal production volume. The one-to-two function is especially suitable for large-scale continuous production operations of small and medium-sized castings. Any one intermediate frequency furnace can perform melting operations with high efficiency, and the other furnace can be kept warm or preheated the cold furnace. The power can be distributed as needed. The two furnaces can The total power used is constant.
The main technical parameters
3、Xi'anMedium frequency melting furnaceinduction coil
Xi'anMedium frequency melting furnaceofInduction coilAssembled by solid, durable and highly conductive T2 copper tubes. The multiple processes of the Haishan Electric Furnace are strictly controlled and formed in one winding. The arc-shaped insulating gaskets between turns ensure uniform spacing between coils and facilitate the discharge of moisture. After the coils are formed and sandblasted, the outside is tightly wound with insulating materials, one-time Pouring molding is stronger and more durable than the traditional method of applying glue. There will be no gaps after long-term use, which greatly reduces the cost.Xi'anMedium frequency melting furnaceThe risk of furnace leakage extends the service life of the coil.
existXi'anMedium frequency melting furnaceThe furnace top and furnace bottom are equipped with formed heat shields and short-circuit ring composite leak-proof probes, which are an important part of the entire furnace leak protection system. At the same time, it also ensures that the molten iron is grounded to ensure operator safety.
4、Xi'anMedium frequency melting furnacehydraulic system
Xi'anMedium frequency melting furnaceThe hydraulic pump station is designed for tilting a full furnace load and consists of a hydraulic pump and a driving motor, an emergency pump, a motor starting device, an oil tank, an oil return and oil suction filter device (and an overflow prevention device). There is a mark inside the fuel tank that displays both the liquid level and the oil temperature.
The tilting furnace operating platform is equipped with oil pump start and stop buttons and oil pump operation indicator lights, furnace body (raising and lowering) manual joysticks and multi-way valves. The motor and oil pump functions of a single set of hydraulic pump stations, one set of hydraulic pumps can be used for one purpose One preparation.
The oil cylinder is designed to use fatty acid as the hydraulic medium, and all hydraulic seals are suitable for fatty acid grease. The hydraulic pump station is equipped with a tubular heat exchanger to cool the hydraulic medium. To ensure the safety of the system, it is also electrically equipped with a function of automatically stopping the pump if it is operated hydraulically but idle for 15 minutes without operation.
If the hydraulic pipeline ruptures, there is an emergency tilting interface on the furnace platform. The molten steel can be dumped by pulling up with a crane or hoisting wire rope.
5、Xi'anMedium frequency melting furnacefurnace leak detection
Xi'anMedium frequency melting furnaceThe leakage furnace insulation resistance detection device is equipped with differential current mode and DC injection insulation resistance detection circuits, indicator lights, leakage current meters and detection control circuits. The DC injection detection system requires a stainless steel probe to be embedded in the bottom of the furnace when the furnace lining is newly built. The stainless steel probe contacts the molten iron at multiple points to ensure that the molten iron is grounded and the detection system is reliable. During normal operation, it detects connections. The power will be automatically turned off when the following conditions occur:
a. Liquid metal penetrates through the furnace lining and reaches the induction coil;
b. There is too much moisture in the furnace lining;
c. Individual resistive components have low resistance to ground.
