An induction melting furnace with fast melting speed, easy control of furnace temperature, and environmental protection and energy saving is:
An induction melting furnace includes a furnace body and a furnace cover fixed on the top of the furnace body, characterized in that the furnace body is provided with an induction coil and a quartz sand closed base made of copper tube coils wound in parallel and in parallel. The sand-sealed base is located at the bottom of the induction coil; both ends of the induction coil are fixed to the insulating plate on the front side of the lower part of the furnace through copper bars, and the ports at both ends are connected with water nozzles; Refractory bricks; a steel outlet is provided on the rear side of the furnace cover; a connecting flange is provided on the outer wall of the central part of the furnace body. Because the above technical scheme is adopted, compared with the prior art, the utility model has the following advantages: 1. Constant power
Output, fast smelting speed, easy control of furnace temperature, and environmental protection and energy saving; 2, with multiple protection measures such as overcurrent, overpressure, current limiting, pressure limiting, etc., on the premise of ensuring the melting speed, make the equipment more reliable, too The maintenance cost is greatly reduced; 3. The heating temperature is uniform, the burning loss is small, the metal composition is uniform, and the casting quality is good.
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
In the picture: 1-furnace body; 2 a furnace cover; 3 a steel outlet; 4, 5 a refractory brick; 6-copper row; 7 a insulating plate; 8-water nozzle; 9- induction coil; 10- connection method Blue.
As shown in FIG. 1, it includes a furnace body 1 and a furnace cover 2 fixed on the top of the furnace body 1. The furnace body 1 is made of thick high-quality aluminum alloy, which reduces the magnetic leakage while ensuring the strength of the furnace body, the structure is reasonable, the volume is small, and the installation is convenient. The furnace body 1 is provided with an induction coil 9 and a quartz sand closed base which are wound in parallel in parallel with a copper tube coil. The quartz sand closed base is located at the bottom of the induction coil 9; both ends of the induction coil 9 are fixed by a copper bar 6 On the insulating plate 7 on the front side of the lower part of the furnace body 1, water ports 8 are connected to the ports at both ends; the upper part and the lower part of the furnace body 1 are respectively fixed with the refractory brick 4, and the steel cover is provided on the rear side of the furnace cover 2. 3; a connecting flange 10 is provided on the outer wall of the middle of the furnace body 1.
Environmental protection and energy saving induction melting furnace converts electrical energy into thermal energy through equipment, and then smelts steel, iron, copper, aluminum and alloys. When the intermediate frequency current passes through the induction coil 9 in the furnace body 1, the electrical energy is converted into magnetic energy in the form of a magnetic field, that is, an alternating magnetic field is generated in the furnace body. When there is a steel material in the furnace body 1, an eddy current is induced in the steel material. This eddy current Makes steel
The material heats up quickly, converting magnetic energy into thermal energy, and finally completing the conversion of electrical energy and thermal energy.
