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…

refractory raw materials

Types of refractory raw materials for continuous casting functional materials and their performance requirements

Functional refractories for continuous casting refer to the integral stopper, (ladle) shroud and immersion nozzle, which are called the three major pieces of continuous casting. Some people also include the ladle slide plate, the tundish slide plate, and the tundish top nozzle. Carbon refractories are commonly known as carbon-bonded refractories. In fact, the flow control…

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…
