hp graphite block factories

The main raw materials for the manufacture of hp graphite block factories are crushed coke and anthracite, and the binder is coal tar or pitch. Compared with other ordinary refractory materials, hp graphite block factories not only have high compressive strength, low thermal expansion coefficient, good abrasion resistance, high refractoriness and load softening temperature, good resistance to rapid cooling and heating, and particularly good slag resistance. Therefore, hp graphite block factories can be used as submerged arc furnace lining materials for all types of ferroalloys that are not afraid of carburization.

However, hp graphite block factories are very easy to oxidize under high temperature conditions, and their thermal conductivity and electrical conductivity are relatively large. In the production of ferroalloys, hp graphite block factories are mainly used to build the walls of submerged arc furnaces that are not exposed to air. The bottom of the furnace.

hp graphite block factories are widely used in the metallurgical industry. Blast furnace hp graphite block factories use the largest amount. Many blast furnace bottoms, hearths and hearths are built with hp graphite block factories; they are also used in aluminum electrolysis tanks and calcium carbide furnaces, industrial pickling tanks, electroplating tanks, and paper industry. Dissolving tanks, reaction tanks in the chemical industry, autoclaves in the petrochemical industry, etc.
