METHOD FOR HOT-REPAIRING HOT-STOVE AND HEAT INSULATING DEVICE USING IT

PROBLEM TO BE SOLVED: To provide a method for safely and quickly repairing only a repairing part without cooling a regenerator, in a hot-repairing of a ceramic burner in a hot stove. SOLUTION: An opening part faced to a combustion chamber side wall in the hot stove is arranged, and a supporting device integrally provided with a main beam 4, an inner cylinder arranged at the center of the main beam 4, an upper step and a lower step rings for fixing a heat insulating supporting beam 6 in a rotatable outer cylinder, a supporting column 5 having a guide ring for inserting the heat insulating plate supporting beam 6 and a heat insulating cap 8 at the top part of the supporting column 5, are prepared. The supporting device is inserted from the opening part of the furnace and fixed, and the heat insulating plate supporting beam 6 and a jig for fitting are connected and the heat insulating plate supporting beam 6 is inserted which adjusting angle with a guide for adjusting the inserting angle, and heat insulating plates 7 divided into plural number are laid on the heat insulating plate supporting beam 6. After removing the jig for fitting, the heat insulating plate supporting beam is rotated and the inserting of the heat insulating plate supporting beam and the laying of the heat insulating plates 7 divided into plural number on the heat insulating plate supporting beam are repeated. The heat insulating plates 7 divided into plural number are combined and the whole hot stove cross section is shut off into the upper side and the lower side.
