Electric furnace

Abstract

Abstract PURPOSE:To obtain a small gaseous phase growing electric furnace having a steep temp. gradient, in an electric furnace having two or more of regions different in a temp. condition, by providing a forcibly cooling heat absorbing region between two regions. CONSTITUTION:A heat absorbing region C is provided between a high temp. region A heated by a heat generator 31 and a low temp. region B heated by a heat generator 32. A pipe 35 having an inlet 36 and an outlet 37 for supplying and discharging a cooling medium is provided in the spacer 33 interposed between the heat generators 31, 32 and a cooling fluid is forcibly sent into said pipe 35 by a pump. Because excessive heat flowing out from the region A is entirely absorbed with the region C and carried out of an electric furnace through the cooling fluid, influence upon the region B is eliminated and a steep temp. gradient is obtained. Because the length of the region C (the distance between the regions A, B) becomes short, the dimension of the electric furnace can be shortened to a large extent.
