Working Principle & Characteristics of Double-station Refining Furnace

图片
The double-station refining furnace is a high-efficiency refining equipment used in the metallurgical industry. It is mainly used for secondary refining of molten steel (such as desulfurization, deoxidation, alloying, temperature adjustment, etc.). It realizes continuous production and improves efficiency through alternating operations of two stations. Working Principle of Double-station Refining Furnace 1. Double-station alternating operation Two stations (A/B) operate independently: one station performs molten steel refining (such as heating, stirring, adding alloys), and the other station performs ladle lifting, preparation or maintenance at the same time, achieving seamless connection. Switching stations through rotation or translation mechanisms reduces waiting time and improves production efficiency. 2. Refining process Heating: Usually arc heating or chemical heating (such as aluminothermic reaction) is used to adjust the temperature of molten steel. Stirring: The composition is...

Operation Matters of Submerged Arc Furnace Smelting

图片
During the smelting process of the submerged arc furnace, operators need to pay attention to the following matters to ensure safety and efficiency: Operation Matters of Submerged Arc Furnace Smelting 1. Preparation Equipment inspection: Ensure that the furnace body, electrodes, cooling system, power supply system and other equipment are normal. Raw material preparation: Prepare ore, reducing agent, etc. according to process requirements to ensure that the quality and particle size meet the standards. Safety protection: Wear protective equipment such as fireproof clothing, gloves, goggles, etc. 2. Loading Uniform loading: Ensure that the material in the furnace is evenly distributed to avoid segregation. Control the loading speed: Prevent uneven reaction or splashing in the furnace due to excessive speed. 3. Power on & temperature increase Power on gradually: Avoid sudden current changes to prevent equipment damage. Monitor temperature: Ensure that the furnace temperature rises acco...

What is The Submerged Arc Furnace Used For?

图片
Submerged arc furnace is an industrial furnace mainly used for smelting high-melting-point metals, alloys or chemical raw materials. It is mainly used to reduce and smelt metal ores, extract the metal components in the ores, and form metals. It mainly produces important products in the metallurgical industry such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and silicon-manganese alloys through chemical reactions under high temperature conditions and using raw materials such as carbonaceous reducing agents and solvents. Submerged arc furnaces are mainly used to smelt the following substances: 1. Ferroalloys: such as ferrosilicon, ferromanganese, ferrochrome, silicon-manganese alloys, etc., which are the main application areas of submerged arc furnaces. 2. Calcium carbide (calcium carbide): used to produce acetylene gas and other chemical products. 3. Industrial silicon: used to produce organic silicon, polysilicon, etc. 4. Other metals: such as phosphorus, tin, etc. ...

What is DC Electric Arc Furnace?

图片
  A DC electric arc furnace is an arc furnace that uses direct current as energy. Like an AC electric arc furnace, it generates heat through an arc between the electrode and the charge (or molten pool), thereby achieving the purpose of melting steel or alloys. It can be used to melt steel or alloys as well as non-ferrous metals. A DC electric arc furnaces is similar to an AC electric arc furnaces, but uses a DC power supply. The current flows between the electrode and the workpiece to form an arc, and the workpiece is melted by the high temperature and melting action of the arc. Features of DC Electric Arc Furnace 1. Ultra-high power supply:  DC EAF can provide higher power, which is very beneficial for smelting high-melting-point metals. 2. No grid interference:  The operation of a DC arc melting furnace will not interfere with the grid, and is suitable for areas with poor grid conditions. 3. Stable high power:  The entire process uses stable high power, which is co...
