Luoyang HongtengIntermediate frequency induction furnace
According to the size of the crucible, the forming method of medium frequency furnace lining crucible can be divided into four kinds: mortar pouring forming method, pressure forming method, furnace forming method, and masonry method. the first two methods are mainly used to make small capacity (below 100 kg) crucible. the latter two methods are suitable for making medium and large capacity crucible. 1、Mortar pouring molding method This crucible forming method is suitable for making special refractory crucible with capacity below 25 kg, such as CaO、BeO、ZrO2、ThO2、Al2O3 crucible. 2、Pressure Molding Method The sand material of the crucible is mixed evenly according to different particle size ratios, then put into the pressure forming mold, and the pressure is applied to make it form. The pressure forming method can be divided into simple pressure forming and isostatic pressing forming. 3、Furnace inside Molding Method The furnace forming method is a widely used crucible forming method. It is suitable for crucible forming with different capacities. The furnace molding method is divided into manual tamping molding method and mechanical vibration molding method. 4、Masonry Method Masonry is the use of special refractory bricks, in the furnace masonry into the crucible. This method is suitable for hot charging...
How does the medium frequency furnace convert electric energy into heat energy to heat metal burden? In short, it includes the following three steps: Alternating current generates alternating magnetic field Induced current generated by alternating magnetic field Induced current is converted into heat energy It can be seen that the whole heating process of the medium frequency furnace is frustrated by the process of energy conversion. First, electric energy is converted into magnetic field energy, then magnetic field energy is converted into electric energy, and most of all-electric energy is converted into heat energy to heat metal. From this point, it can be seen that the heating method of a medium frequency furnace is different from that of an electric arc furnace, plasma furnace, resistance furnace, etc. Many transformations of melancholy energy forms will inevitably lead to losses, so it is called low thermal efficiency. This requires taking measures to compensate from the electrical lines to reduce losses and improve efficiency, thus making medium frequency equipment more energy-saving.
As an advanced heating method, induction heating has the following advantages over traditional heating methods: 1. The heating speed is fast, which can greatly improve the productivity of the heating device and connect it with forging, rolling and other machines into an uninterrupted production line; 2. There is no direct connection between the heated metal and the power supply, which creates convenient conditions for the design and manufacture of the mechanism of the heating device. 3. The heating specification is stable, which ensures the possibility of automation of metal heating and parts processing, and simplifies the production organization of automatic lines and assembly lines. 4. There is almost no oxide scale, which can save metal, prolong the service life of the die, and may transition to the precision die forging process of parts. 5. Universal heating, that is, blanks with different cross-sectional shapes and ratios of cross-sectional and length dimensions can be heated evenly. 6. The working environment in the workshop is good and the working conditions are improved.
