Electric arc furnace steelmaking is one of the main steelmaking methods at present, which has the characteristics of short process, low energy consumption and low carbon emissions. Compared with the “blast furnace-converter” long process steelmaking, the electric arc furnace short process steelmaking uses scrap steel as the main raw material, which has outstanding advantages such…
This study evaluated an artificial neural network model that used historical production data from an electric arc furnace producing stainless steel as training to predict the end-point power demand of future heats. The electric arc furnace used in this study is an AC electric arc furnace with a scrap preheater using furnace gas as the…
The proportion of furnace steel was 24.5%; South Korea’s crude steel output was 71.42 million tons, down 1.4% year-on-year, accounting for 3.8% of the world’s total, of which converter steel accounted for 68.2%, electric furnace steel accounted for 31.8%; Australian crude steel output was 549 10,000 tons, down 3.4% year-on-year, of which converter steel accounted…
Billet continuous casting parameters and tundish refractory configuration A variety of refractory materials are needed in the production and use of the tundish, including castables, smears, dry materials, nozzles, slag retaining wall series, three continuous casting parts, etc. The main configuration of tundish refractories is shown in Table 1. , The main parameters of the…
The wagon dumper is a large-scale mechanical equipment for dumping bulk materials of railway gondola wagons. According to the structure, it can be divided into rotor type, side tilting type, end dump type, compound type, etc. The most widely used is the rotor type wagon dumper. The work efficiency is greatly improved, and the fast…
Raw materials: What are the raw materials used for carbon production? In carbon production, the commonly used raw materials can be divided into two types: solid carbon raw materials and binders and impregnants. Solid carbon raw materials include petroleum coke, pitch coke, metallurgical coke, anthracite, natural graphite and graphite crushed, etc.; binders and impregnants include…
Magnesia-carbon bricks are alkaline refractory materials made of magnesia and carbon materials, using asphalt or resin as binders. It has the multiple advantages of high refractoriness of magnesia refractories and carbon refractories that are difficult to be wetted by slag and molten steel. Because of its high refractoriness, strong slag erosion resistance, excellent thermal shock…
Today we make the following comparative analysis on the differences and technical pros and cons of the traditional top-charging electric furnace, continuous horizontal charging electric furnace and quantum electric furnace. Traditional top-loading electric furnace has simple equipment, occupies less land, less investment, flexible and simple operation, and is suitable for diversified scrap steel; however, the…
The continuous feeding electric furnace is one of the more newly put into production electric furnaces in recent years. The biggest feature is that the scrap is continuously added during the smelting process, and the power can not be cut off without opening the furnace cover. The energy input is uninterrupted, avoiding huge energy loss…
When the electric furnace gas discharges to form an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃. For electric arc steelmaking furnaces, the bottom and walls of the furnace are built with alkaline or acidic refractory materials. During the steelmaking process, the working layer of the inner lining…
