Abstract: PURPOSE:To make the composition of slag uniform, and to recover cast iron included in the slag, by heating desulfurization slag, formed in desulfurization of cast iron with sodium-contg. desulfurizing agent such as soda ash or caustic soda, with electric current applied across electrodes. CONSTITUTION:Cast iron 2 is poured from a blast furnace into a mixer car or a ladle 1, where it is desulfurized with Na-contg. desulfurizing agent such as Na2CO3 or NaOH. The desulfurization slag 3 formed during the desulfurization is transferred to a pan 4 so as to separate it from the molten cast iron 2 and to prevent sulfur from returning from desulfurization slag 3 to the molten cast iron 2. The desulfurization slag 3 consisting of Na2O, SiO2, CaO, Na2S shows wide scattering of composition, and includes a small amount of molten cast iron. Electrodes 5 made of mild steel etc. are inserted into the slag 3 contained in the pan 4, and current is applied from an AC source through a constant-current apparatus 6 so as to heat and hold the slag 3 at molten state. During that time, the included cast iron settles by the difference in specific gravities, then it is recovered. The molten slag 3 is made uniform composition, and cooled, solidified, and crushed at outside of the pan 4, and is utilized as ballast for road.

And then, are formed a groove having a vertical side wall and an oxide film 108 on the whole surface, thereby burying an etched portion back again. Next, an exposed portion of the substrate 101 is subjected to anisotropic etching with the oxide films 102 and 108 as a mask, thereby forming a vertical groove 113. An oxide film 114 is further deposited to a high thickness on the whole surface so that the groove 113 is buried back to a satisfactory extent. Then, the oxide film 114 is etched back while the oxide film 102 is removed at the same time, thereby flattening the surface. As a result, an element formation region 115 formed on the surface of the board 101 is directly interfaced with the groove 113 based on a self-alignment so that it is possible to realize a structure separated by a base collector separation region 116 formed by the oxide film 108 as well.
