- Optimal control of electric arc furnace steelmaking process1. Cost control optimization systemIn recent years, the University of Science and Technology Beijing has adopted the theory of space-time multi-scale structure to study the electric arc furnace steelmaking process, and pointed out that there are multiple space-time scales such as micro-scaleZBTECH News November 13, 2020
- Electric arc furnace: the characteristics of the refractory materials used in each part1. Refractory materials for electric arc furnace roofThe roof of the electric arc furnace is generally built with high-alumina bricks with an alumina content of 75%-85%. Compared with silica bricks, high-alumina bricks are characterized by high refractoriness, good thermal shock resistance, and highZBTECH News November 16, 2020
- Steelmaking electric furnace: introduction to the advantages of its tube water-cooled furnace coverThe existing furnace covers of steel-making electric furnaces mostly adopt the structure of masonry refractory bricks. The disadvantages of the furnace covers of this structure are many brick cracks, poor overall performance, high energy consumption, short service life, and long maintenance.ZBTECH News November 18, 2020

- Electric arc furnace environment and conditionsElectric arc furnaces used for smelting generally have three characteristic working stages:· At the beginning of the melting stage, the solid charge is melted and the energy demand is the largest· Initial refining and heating stage· During the refining period, the input energy at this stage onlyZBTECH News November 27, 2020
- What is ladle furnace?Secondary Refining Ladle Furnace Secondary Refining or Secondary Metallurgy is defined as any post steelmaking process performed at a separate station prior to casting and hot metal desulfurizaion. It does not include normal alloying practice in the furnace or at the ladle during tapping. ThisZBTECH News March 11, 2020
- How the chagred scrap melting in EAFEAF Melting Process The melting period is the heart of EAF operations. The EAF has evolved into a highly efficient melting apparatus and modern designs are focused on maximizing the melting capacity of the EAF. Melting is accomplished by supplying energy to the furnace interior. This energy canZBTECH News March 11, 2020
- VOD furnace decarburization processVOD furnace decarburization process The VOD furnace decarburization process is a process for removing carbon from materials. Its refining is mainly controlled by the supply rate (intensity) of oxygen, the height of the top-blowing oxygen gun, the degree of vacuum (the number of vacuum pumpsZBTECH News February 13, 2020
- Difference between AOD & VOD stainless steel making processAOD production (Argon-Oxygen-Decarburization) In this process the merger is implemented in conventional furnace. Subsequently, the liquid passes to the converter, within which the steel undergoes the refining chemical analysis through redox reactions. Blowing argon and oxygen, using sheets, maintZBTECH News January 10, 2020
