converter steelmaking

Types of converter steelmaking and analysis of damage mechanism of refractory lining used

Converter steelmaking is currently one of the most widely used steelmaking methods in the world. It has become the mainstream steelmaking method due to its high efficiency, short smelting cycle, low steel production cost, and suitability for the smelting of multiple steel grades. According to statistics, converter steelmaking accounts for more than 70% of the…

Brief introduction of graphite electrode use technology

Varieties of graphite electrodes Electric arc steelmaking furnaces are generally divided into three categories, namely ordinary power electric furnaces, high power electric furnaces and ultra-high power electric furnaces. Corresponding to the power level of electric furnace steelmaking, graphite electrodes are also divided into 3 varieties accordingly, namely ordinary power graphite electrodes (code RP grade), high…

continuous casting tundish

The determination of the structural parameters of the continuous casting tundish and the configuration of refractory materials

  In layman’s terms, the tundish (picture 2 above) is a refractory container, which is used to contain molten steel poured from the ladle (picture 1 above), and then diverted to each mold (picture 3, 6 above). Reduce pressure to stabilize steel flow. The height of the liquid level in the ladle is at least…

ladle slide plate

The mechanism affecting the damage of the ladle slide plate and the advantages and disadvantages of several commonly used materials

Before talking about the reasons for the damage of the ladle slide, we first have a general understanding of the sliding mechanism of the ladle. The structure diagram of the nozzle and the sliding plate is as follows:   The ladle sliding nozzle is composed of a sliding mechanism, an upper nozzle, a sliding plate,…

ramming material at the bottom of electric furnace

Knowledge about dry ramming material at the bottom of electric furnace

At present, the working layer of high-power and ultra-high-power electric furnaces is generally constructed with magnesia dry ramming material. The working layer uses refractory materials to directly contact molten steel and slag, and directly bear high-temperature thermal load and corrosion of molten slag, and erosion of molten steel and steel scrap. Mechanical impact and oxidation…

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…
