  A coreless type induction furnace is a metallurgical device operating on the principle of electromagnetic induction. Its main characteristic is the absence of a closed iron core structure within the induction coil. It consists of a furnace frame, an induction coil wound with shaped copper tubing, and a crucible made of a special material. This design reduces capital and installation costs and increases the flexibility of alloy selection. Coreless induction furnaces also feature safety features such as anti-vibration structures, a leak detection alarm system, a parallel coil structure, and a high-efficiency IGBT inverter power supply, all ensuring efficient and safe operation. Structural Features of Coreless Type Induction Furnace The furnace body employs a layered design. The induction coil is constructed from shaped copper tubing with varying wall thicknesses (10-15mm inner wall/2-4mm outer wall), and the electromagnetic field strength is enhanced by parallel silicon steel sheet...

  An AOD refining furnace (Argon-Oxygen Deoxidation) is a device used for refining stainless steel, utilizing argon and oxygen for decarburization. This method is simple to operate, convenient, and has low production costs, making it widely used in the smelting of low-carbon and ultra-low-carbon stainless steel. The AOD furnaces design is similar to a converter, mounted on a tilting support ring. The AOD melting furnace achieves decarburization while retaining chromium by controlling the argon-oxygen ratio to reduce the partial pressure of carbon monoxide. It is an important smelting device for the final deoxidation and alloying of molten steel. Refractory Materials for AOD Refining Furnace Magnesium-calcium based refractories are commonly used in AOD furnaces because the calcium oxide (CaO) effectively resists high-basicity slag and reacts with SiO₂ and other phases in the slag to form high-melting-point phases, improving corrosion resistance. The following are some of the main ty...

  Ultra-high power electric arc furnaces (UHFAs) are primarily used for heating and melting scrap steel, utilizing the high energy density generated by an electric arc to accomplish this process.  These melting furnaces are characterized by short smelting times, automation through computer control, optimized metallurgical processes, and the collection of production data. This technology originated in the mid-1960s, aiming to achieve higher power input while reducing refractory material consumption by altering the characteristics of the electric arc.  The application of steelmaking electric furnaces benefits from their rapid melting capabilities and efficient production control. Applications of Ultra-High Power Electric Arc Furnaces What is an Ultra-High Power Electric Arc Furnace? First, we need to understand its definition. The power level of an EAF is usually measured in "transformer capacity per ton of steel (kVA/t)". Ordinary power electric arc furnace: Approximately ...

  Titanium slag production employs an electric furnace smelting process (classified by shape into circular and rectangular furnaces). Titanium slag electric furnace can be categorized into three types based on their enclosure method: closed submerged arc furnace, semi-closed electric furnace smelting, and open electric furnace smelting. The Principle of Titanium Slag Electric Furnace Smelting 1. The Principle of Titanium Slag Smelting The principle of titanium slag production using the electric furnace method involves mixing ilmenite with a solid reducing agent (anthracite or coke, etc.) in a specific ratio and adding it to a submerged arc furnace for reduction smelting.  Iron oxides in the minerals are selectively reduced to metallic iron, while titanium oxides are enriched in the slag. After slag-iron separation, titanium slag and the byproduct metallic iron are obtained. 2. Raw Materials for Titanium Slag Smelting 1) Ore:  The titanium ores used for producing titanium ...

  Submerged arc electric furnaces, also known as electric arc furnaces or resistance furnaces, are primarily used for the reduction and smelting of ores, carbonaceous reducing agents, and solvents to produce ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and ferrosilicon-manganese alloys, as well as chemical products like calcium carbide. Submerged arc furnaces smelt using electric arc or resistance heating. Based on the power supply method, they can be classified as AC, DC, and low-frequency submerged arc furnace. Their submerged operation minimizes air exposure and improves smelting efficiency. SAF smelting furnaces are crucial equipment in the metallurgical and chemical industries, playing a key role in modern industry. Main Applications of Submerged Arc Electric Furnaces Ferroalloy Production:  Obtaining ferroalloy products such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and ferrosilicon-manganese alloys by reducing and melt...
