Luoyang HongtengIntermediate frequency induction furnace
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,...
As the main equipment of the forging industry and the foundry industry, the electric furnace has some points that need to be paid attention to in its daily use. Today, the editor of Hongteng will share with you the knowledge about the use of the electric furnace. First of all, when installing the electric furnace, it is necessary to standardize the connection between the transformer, the intermediate frequency power supply, and the intermediate frequency electric furnace, and select cables of suitable materials. Especially for induction coils and water-cooled cables, increasing their cross-sectional area can effectively reduce current heat loss. The intermediate frequency electric furnace can use a special rectifier transformer to increase the supply voltage and limit the no-load operation of the transformer. Select the appropriate capacity and frequency medium frequency electric furnace according to the casting process, increase the power density to improve the melting efficiency and reduce the additional loss. Regarding the material of the furnace body, you can choose according to your actual situation. If your output is relatively large, we will recommend that you choose the steel shell furnace body first to reduce the heat loss and electromagnetic loss of the furnace wall and furnace mouth....
When the electric furnace is working, not only the temperature in the furnace is high and the change is large, but also it is subjected to strong electromagnetic stirring and the impact of the charging charge, which will cause the lining of the electric furnace to be easily damaged. Therefore, the quality of the lining of the induction furnace directly determines the life of the furnace, which will ultimately affect the production capacity of the entire production line. We previously had an article “Construction Method of Knotted Material for Intermediate Frequency Furnace”, which once introduced the knowledge of knotting of furnace lining to you. Today, let’s expand it and share some knowledge about furnace lining sintering. After the furnace lining is finished, the furnace and sintering process can be carried out. The purpose is to fully remove the moisture in the furnace lining, so that the silica sand is fully and uniformly transformed, and finally sintered at high temperature into a dense ceramic surface with high strength. When baking and sintering, we need to pay attention to the following items: Before the oven, a detailed inspection of the water cooling system, tilting system, control loop and various markings should be...
