Claims (2)

1. A method of replacing vertical plate coolers in a mine shaft of a blast furnace, including fire cutting of a furnace casing with refrigerators 1/8 of the furnace perimeter during major repairs, characterized in that for current repairs the casing is cut along the contour of the stove, sheets are welded along its perimeter, pressed with jacks formed inside a box furnace at half the width of the sheet and it is attached to the housing, fixing bolts and burn cooling tubes of the refrigerator and the replaced set in their place plugs, the patch is welded new casing with cooling pipes to the side sheets, remove the mounting scarves and push the box with jacks, weld the patch flush with the casing of the furnace and fill the internal cavity of the new refrigerator with a refractory mixture.
2. The method according to claim 1, characterized in that the pressing force of the hydraulic jacks is determined by preliminary measurement of the coefficient of active weight and lateral pressure of the charge on the stopped furnace.
