Luoyang HongtengIntermediate frequency induction furnace
Let us introduce the products, intermediate frequency furnaces, and induction melting. When choosing the best melting furnace for your foundry, it is important to understand how they operate. Induction furnaces work by transferring thermal energy through a high-voltage primary coil that induces a high current, low voltage, or secondary coil. These types of furnaces are ideal for melting a wide variety of metals while maintaining low melting losses. There are two primary varieties of these furnaces: coreless furnaces and tunnel furnaces. Coreless Furnaces: Coils are the main heating component of a coreless furnace. The stove takes its name from the coil, which is made of highly conductive copper tubing and wound into a helical coil before being placed in a steel casing. To reduce the risk of overheating, the coils themselves are water-cooled through a circulation tower. The frequencies used can vary between 50 cycles per second and 10,000 cycles per second (referred to as mains frequency and high frequency, respectively). The higher the frequency, the more power can be applied to the furnace. Once the material reaches a molten state, the interaction between the magnetic field and the electric current creates a stirring reaction that helps mix the alloy...
Many users hope that after purchasing a new electric furnace, they will not operate it. Today we will explain some basic common sense about the operation of the intermediate frequency furnace. The first is the boot operation. After assembling the incoming line device, we need to observe whether the voltage and ammeter indications are normal. Adjust the potentiometer to adjust the power to the minimum value. Press the power on button, after 2 to 3 seconds, press the “main circuit on button”, then press the “inverter start button”, the intermediate frequency power supply starts to work, at this time the DC voltmeter, ammeter, intermediate frequency frequency meter, power meter There are instructions. After the startup is successful, slowly adjust the power knob to the desired power position and input the power. If the intermediate frequency is not established (failure to start), press the “Inverter Stop” button to reset it, and then press “Inverter Start” again. IF furnace shutdown operation When shutting down, first turn the power adjustment knob to the smaller position, and then press the “inverter stop” button. If it needs to stop for a long time, first press “inverter stop”, then press the main current disconnect button, and...
Whether you run a foundry company, an auto parts company, or any other industry that requires casting metal, you probably need an industrial-scale induction furnace. Although from the looks of it, many people may think that stoves are all the same, but this is wrong. There are two main materials for induction furnaces: aluminum and steel. These two different types of furnaces are suitable for different types of metals. Today, Hongteng editors share with you some common casting metals, and the most suitable furnace types for them: gold As one of the more common cast metals, gold is used for several primary functions. One is jewelry. No matter what type of jewelry you make, you’ll probably need to do some casting. Aluminium furnaces are probably the best choice for smelting gold, as it is generally required to cast less gold than steel or other metals. Aluminum furnaces typically heat up faster than the competition, making them the perfect efficient choice for gold furnaces. silver Like gold, silver typically doesn’t melt in large quantities, so efficiency is key. This fact makes aluminum furnaces often a better choice for casting silver. copper No matter what you do with copper, finding the right...
When the user smelts metal and needs to buy a new smelting furnace. We would recommend users to choose our induction stove. There are mainly the following considerations. Environmental friendly Using other furnaces produces a lot of waste, such as dust and pollutants, which can diffuse into the atmosphere. These wastes are often difficult to dispose of and are also harmful to the environment. But that’s not the case with induction stoves, and if you care about the environment, induction stoves are ideal for you. Oxidation Our coreless induction melting furnaces will provide you with low levels of oxidation during the melting process. A lower oxidation rate during melting means you’ll get a higher yield, which increases your productivity. Therefore, the oxidation rate must always be checked when purchasing an industrial furnace. customizable size Industrial induction furnaces have a custom induction heating coil to suit different operating levels. These furnaces come in different sizes, the smallest of which usually require small refraction of the material. If your business is small, it is advisable to buy a small induction stove. We can determine your final selection based on your expected production scale. Improve productivity Induction heating coils heat induction furnaces in...
Aluminum is the most abundant metal in the earth’s crust, and there are many places where aluminum is used in our lives. We can generally obtain aluminum by electrolysis. Another method is to smelt scrap aluminum by purchasing an induction melting furnace. The molten aluminum melted in the smelting furnace is recast into aluminum ingots, which are finally made into the products we need. How does a new aluminum melting furnace work? Earlier we talked about the heating principle of the induction furnace. When current flows through the induction coil, a magnetic field is formed. Applying alternating current through this coil will cause the magnetic field to change direction at the same rate as the frequency of the alternating current. When the aluminum charge is added, Faraday’s law takes over. The induced voltage will cause a current to flow through the material in the magnetic field. When current flows through the material, the movement of electrons is resisted. Materials that are more resistant to the flow of electrons emit more heat when current flows through them. Induction heat is generated in the material of the product by means of an electric current. The heat from the surface of the product...
Crucible is a component that is often used in induction furnaces when smelting metals. In addition to being used to hold molten metal for smelting, the crucible also plays the role of heat insulation, insulation and energy transfer. Common intermediate frequency furnace crucibles mainly include alkaline crucibles, acid crucibles, and neutral crucibles. Today, the editor of Hongteng will introduce to you the advantages and disadvantages of acid crucibles. Advantage: 1. The acid slag has high viscosity, low air permeability and good isolation effect on the atmosphere. The amount of hydrogen and nitrogen absorbed by molten steel from the atmosphere is small, and the gas content in the final product is low. 2. The inclusions in the acid crucible steel are mainly silicates, and there are almost no aluminates inclusions. The former has a low melting point and is easily removed by polymerization. Therefore, the brittle inclusions of the steel smelted by the acid crucible are less and the purity is high. 3. There are few silicate inclusions in molten steel, and there are few high melting point inclusions. In addition, the silicon content in the molten steel is relatively high, and the fluidity of the molten steel is good. Therefore,...
