The main function of the induction furnace is to make steel. The development of induction furnaces is therefore good news for small steel producers. The induction furnace is mainly composed of a crucible, an induction coil, a casing, a cooling system and a tilting mechanism. The crucible is made of refractory material, and the furnace plate is lined with refractory material. The crucible holds the charge and subsequently the melt. The choice of refractory material depends on the type of charge and basically consists of acidic, basic or neutral refractory materials. These furnaces are easy to install, operate and maintain. These furnaces have smaller thermal dimensions and lower investment costs, making them the first choice for steel mills with lower capacity. In these furnaces, steel is produced by melting the charge using the heat generated by an electromagnetic field. The enclosure is the outside of the furnace. This houses the crucible and induction coil and has a higher heat capacity. It is made of cuboids and mild steel plates and is joined at the corners by non-magnetic metal corner pieces and edge carriers of the strips. Raw materials and energy Scrap, DRI pig iron, cast iron are input raw materials...
In the metal handling industry, when you’re planning to invest in your next project, you want to make sure you’re buying the right product. There are many different metal heating appliances on the market, and a large number of suppliers do not always clearly communicate their prices and products. To select them is not always an easy process. Today, Hongteng editors come to give you some suggestions. Hopefully these tips will help you find the right induction furnace for you. The first thing to do is to decide on a budget. Your budget is the most important part of all aspects of your business, from marketing to security. Therefore, you need to make a good budget before making a big purchase. Not only can an accurate budget help you eliminate unrealistic choices, it can also help you understand any issues that may arise as you prepare for your next project. For example, did you know that the frequencies used in induction melting can vary between 50 cycles per second (mains frequency) and 10,000 cycles per second? Those on a higher budget may need to find an induction stove that can handle higher frequencies. However, those on a budget may still...
Induction furnaces are commonly used to melt steel and precious metals. Because of its good heating effect, it can be used in various industries and has had a huge impact on many industries. If you are looking for an induction furnace for your foundry, you should consider the following factors before purchasing. Induction Furnace Dimensions Melting furnaces are available in different sizes. Generally, induction furnaces take up less space and are therefore suitable for foundries of all sizes. You’ll find that the capacity options for induction cooktops are huge. You need the needs of the foundry to guide the size of the induction furnace you purchase. Control Features of Melting Furnace Additionally, the ideal induction stove for sale should have temperature controls that allow you to adjust the power to the stove. Metals have different melting points. For example, steel melts at 1370 °C. Therefore, controlling the power consumed by the induction furnace will help you melt the metal at the proper melting point. This will ensure that you produce a quality product. Before purchasing an induction furnace for sale, make sure you are satisfied with the controls of your induction melting furnace for sale. Oxidative loss Ideally, a used...
Induction furnaces use the induction principle of a transformer, and when an electrical conductor is placed in a fluctuating magnetic field, a voltage is induced in the conductor. In a crucible furnace, this voltage creates strong eddy currents that, due to the electrical resistance of the material, cause the material to be heated and eventually melted. In the process of heating steel, a large amount of electricity is required. In addition to the theoretical energy required to produce steel, energy is also required to compensate for losses that occur when producing steel. Energy loss increases specific energy consumption and reduces furnace efficiency. Today we are going to learn about the energy loss of some induction furnaces during operation. Losses in steel production heat loss Furnace Coil Loss Capacitor Bank Loss Converter losses Primary side transformer losses. Heat loss is the main loss and contributes the most to the energy loss. The main heat loss of induction furnace: Radiation loss from furnace top Conduction loss of refractory lining Heat Loss in Coil Cooling Water Heat carried by removed slag Heat carried by the gas exhausted from the furnace top In the process of generating heat, the furnace continuously loses heat to...
Steel is so strong and has many effects on our lives. Humans have used this metal as a resource to make our vehicles since 1800. Steel forging and automobile manufacturing are quite long and interesting processes. If you want to learn more about how to melt steel into auto parts to keep us safe on the road, keep reading. Which auto parts require steel? Steel is used for gears, engine parts and the body of the car itself. It’s a very solid substance, yet malleable if exposed to the right elements. It is also easy to bond metal parts to other parts when welding, making it ideal for trains, planes and cars. Using an induction furnace for melting steel First, the model is sketched out. Each design is configured down to the last detail before the steel is melted. Then, the melting process can begin. Because the melting point of steel is so high, a unique furnace is required to melt it to a usable temperature. The melting point of steel is as high as 1370°C. More than a simple furnace is required to melt and shape this sturdy metal. This is where the induction forge comes into play. Furnaces...
When the capacity of the steelmaking production line is relatively small, the intermediate frequency coreless induction furnace is a very suitable choice. The induction hob is equipped with a converter that converts the 50 Hz frequency of the mains into the necessary intermediate frequency. The regulation of the converter is performed by the built-in control electronics. Control of the furnace is carried out using the equipment in the operating cabinet and, if necessary, with the aid of a processor. Most of the time, induction furnaces also require a transformer for energy supply. The furnace transformer is connected to the power supply network. A transformer converts the mains voltage to the voltage required for the furnace to operate. Transformers are often equipped with built-in monitoring devices such as thermometers, oil level monitoring, Brinell relays and air dehumidifiers. Smelting is carried out in refractory crucibles, usually made of acidic or neutral amorphous refractory materials. The crucible is heated by induction furnace coils surrounding the crucible. Heating in an induction furnace consists of certain cyclic activities. These activities are called “thermal cycles” or “production cycles”. The thermal cycle has two components, the melting cycle and the non-productive cycle. The melting cycle is the...
