Carbon baking furnace is a kind of thermal equipment which can indirectly heat various carbon products after high pressure forming according to the specified baking temperature under the condition of isolating air, so as to improve the electrical and thermal conductivity of the products and improve the strength of the products.
Electrolytic aluminum is aluminum obtained by electrolysis. Cryolite - alumina molten salt electrolysis is used in modern electrolytic aluminum industry. Molten cryolite is a solvent, aluminum oxide is use as solute, carbon body is used as anode, aluminum liquid is use as cathode, strong direct current is introduced, and then electrochemical reaction is carried out on two poles in an electrolytic bath at 950 - 970 deg c, so that electrolysis is carry out.
