FIELD: melting or distributing furnaces associated with remelting of metals. ^ SUBSTANCE: the melting cavity with heaters located in it, the heaters pass outside through the brickwork, where they are cooled for production of the conditions of melt crystallization inside the brickwork thus providing the furnace leak-proofness, the minimum thickness of the brickwork is determined by an empirical relation: dmin=a+b(Tf-Tmelt)/Tmeit+C[Theat/Tmelt-Theat)]2, where: dmin- the minimum wall thickness; Tf - the temperature of metal inside the furnace; Tmelt- the metal melting point; Theat- the temperature of the outside end faces of heaters; a, b, c - empirical coefficients equal to 10, 25 and 2,2 cm respectively. ^ EFFECT: enhanced capacity of the furnace. ^ 1 dwg |
