Abstract
PURPOSE:To keep a converter hot economically with the sensible heat of molten slag, by inverting the converter when it is suspended, and by fitting the opening of the converter with a heat-keeping lid filled with molten slag. CONSTITUTION:In the short-time suspension of a converter 1 for the purpose of periodical repairment or of production adjustment, the converter 1 is inverted so as to direct the inlet 1a downward. A heat-keeping lid 7 filled with molten slag 13 is placed under the inlet 1a and is fitted to the inlet 1a tightly in order to heat the inside of the converter 1 with the sensible heat of the molten slag 13. The heat- keeping lid 7 is revolvably mounted on the top end of an arm 8 which revolves around the pin 11 of the bracket 10 of a traveling track 6. At the other end of the arm 8 is mounted a balance weight 12 of a weight corresponding to the total weight of the lid 7 and the molten slag 13. The arm on the balance weight side is pushed by a power cylinder 14 attached to the traveling track 6 in order to raise the revolving arm 8 around the pin 11, and to oscillate the arm 8 by a cylinder 15, hereby the heat-keeping lid 7 is fitted tightly to the inlet 1a of the converter 1.
