Ladle furnace is mostly used in the refining of bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and other steel types. Electric arc furnace, LF and CCM combine into a high efficiency short process production line with remarkable refining effect. The LF can refine the liquid with…
For the electric furnace steelmaking, ingredients is related to whether the melting can smoothly operate andcost of the production. The reasonable ingredients can shorten melting time. Firstly it should carefully calculate correctly and accurate weighing the charge, next the size of the furnace charge should be fit proportionally. Thirdly various ingredients…
In principle, investors of EAF-steelmaking project should check carefully whether there are enough prerequisite conditions, then make a thoughtful plan of the project. Following five crucial factors should be primarily reviewed: 1.Product positioning Product positioning mainly includes product kinds, specifications and product quantity. It is difficult for a steel plant…
Steelmaking production is progressing towards more clean and more high efficiency along with many technologies put into practical application. Scrap crushing and sorting technology Scrap is mixed with ferrous metals, non-ferrous metals, non-metals, and should be crushed and sorted before charging into the furnace. Apart from separation, the paint and coating…
Scrap is the main material for EAF steelmaking. Scrap quality has a direct impact on steel quality, cost and furnace productivity. Therefore scrap should meet following requirements before charged. The surface of scrap steel should be clean and less rust, sand and other sundries in scrap will reduce the conductivity…
Generally, in the steelmaking process classification of the EAF is based on specific working features. such as nature of power supply, furnace lining type, charging mode, output power of furnace transformer and tapping mode of molten steel. Common the EAF can be classified by its below features. Power supply nature:…
Scrap steel is the main raw material for arc furnace smelting. As social scrap steel contains a large amount of Cu, Sn, As, Pb and other harmful elements that are difficult to be removed. Applying some replacements of scrap can helpfully improve this situation, hot metal (pig iron), direct reduction iron…
In practical melting process, these two kinds of furnaces have its advantages and disadvantages. Thermal Efficiency IF has higher thermal efficiency and can quickly heat the charging materials; for EAF, a great amount of arc heat is lost through the cover and furnace wall. Metallic Yield As there is no…
Served as an essential and indispensable equipment in steel industry, EAF(Electric arc furnace) has unquestionably become the propellent of technical progress in the steelmaking sector. When look back, we can clearly see several key turning points that EAF have come through. 1900s – Origin of EAF As we all know,…
In order to help customer recouping the capital of the new rolling mill factory ASAP, even under the epidemic condition, SME operation team still fly to Ethiopia last month. After 14 days quarantined in Skylight Hotel in Addis Ababa, they fly to Mekele immediately. Normal pre-production maintenance has been completed, this week…
