What are the characteristics of graphite rotors with graphite support rods compared with other rotors? 1. In aluminum foil casting, aluminum alloy hub and other aluminum processing industry, the cycle is up to 2 months. 2. The rotating refining degasser is divided into movable and fixed mode, which can be applied to different operating environments. The 3. Degassing rate is above 50%, the smelting time is shortened and the production cost is reduced. 4. is suitable for purifying the aluminum liquid in the crucible furnace, the ladle and the static box. 5. Surface after oxidation treatment, the service life is about 5 times of the ordinary product, widely used in the aluminum alloy casting industry. There is a special application…
The silicon carbide crucible is a bowl shaped container with a deep ceramic bottom. When solid is heated by fire, crucible must be used, because it can withstand high temperature more than glassware. This is also the reason why the silicon carbide crucible is used by the public. First of all, the use of the silicon carbide crucible is introduced, hoping to help everyone. The crucible usually does not fill the melt too much to prevent the heat from jumping out and allowing the air to pass in and out freely to allow for possible oxidation. Because the bottom of the crucible is very small, it is usually needed to be heated directly by the fire on the mud triangle.…
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…
