electric arc furnace steelmaking

Clean and intelligent production technology of electric arc furnace steelmaking

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…

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 processing process of graphite electrode

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…

There are many types of antioxidants for magnesia carbon bricks, how to choose them correctly?

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…

Comparative analysis of the advantages and disadvantages of top charging electric furnace, continuous horizontal charging electric furnace and quantum electric furnace

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…
