Electric arc furnace steelmaking is based on electrodes to generate arcs, so that electric energy can be changed into heat energy in the arc, melting furnace burden and removing impurities such as sulfur and phosphorus, adding necessary elements (such as carbon, nickel, manganese, etc.) to smelt steel or alloy with various properties. Electric energy heating can accurately control the temperature of the furnace and produce low temperature waste gas. The heat efficiency of the arc steelmaking furnace is higher than that of the converter. Technology development has a history of about 100 years in EAF steelmaking, although other methods always face the steelmaking challenges and competition, especially the high efficiency oxygen steelmaking impact, but the proportion of steel production of…

Graphite heat exchanger is a heat transfer device made of graphite. The graphite in the manufacture of heat exchanger should be non transparent, and is often used in the non - permeable graphite and graphite. Characteristic Graphite heat exchanger has good corrosion resistance, heat transfer surface is not easy to fouling, heat transfer performance is good. However, the graphite is easy to crack, the bending and tensile strength is low, and it can only be used for the low pressure, even though the pressure is the best piece of porous structure, the working pressure is generally only 0.3 ~ 0.5 mpa. Graphite heat exchanger with high cost, large size, use is not much. It is mainly used in the heat…

Graphite gaskets that made by pure graphite plate or metal (teeth plate, plate, net) reinforced graphite plate cutting or stamping, has many excellent sealing performance, such as: thermal stability, self lubrication, corrosion resistance, aging, not brittle, etc., in the harsh conditions of the conditions can be used for a long time, very few need to maintain. Lining material can be different with different metal plate. Type optional without edge, inner edge, out sourcing side, inside and outside wrapping. Graphite cut gasket is from pure graphite plate punching or cutting into the, it has good corrosion resistance, resistant high / low temperature, good compression elasticity and high strength, a variety of circular complex geometric gasket is widely used in pipes, valves,…
