摘要： PURPOSE:To prevent the damage of furnace wall refractories owing to thermal impact and to shorten the term of work for construction and relining in startup of a vertical furnace by charging a raw material into the furnace after a short period of simple drying with heating air and introducing temp.-controlled heating gas into the furnace. CONSTITUTION:The inside of a furnace is emptied upon building of refractory walls and is subjected to heating and drying using heating air for the purpose of removing moisture from the refractories and the mortar or the like used for the building and for the simple calcination of the mortar or the like. A raw material is thereafter charged into the furnace and temp.-controlled heating gas is introduced into the furnace through the tuyere in the lower part. More specifically, the waste combustion gas generated in the regenerating stage of a hot stove attached to a blast furnace and the high temp. gaseous N2 obtd. in a blasting stage are used alone or in combustion, and the temp. thereof is regulated by adding gaseous N2 of an ordinary temp. or some air thereto. The concn. of O2 in the heating gas is regulated to

摘要： PURPOSE:To heat insulate a hot blast stove by reduced fuel while preventing the damage of the silica brick of a checker, by partially holding the temp. of silica brick of the checker in the hot blast stove to a specific temp. range during the shutdown of the hot blast stove due to the shutdown of operation of a shaft furnace. CONSTITUTION:In an external combustion type hot blast stove wherein a heat storing chamber 1 and the dome parts 15, 16 of a combustion chamber 2 are connected by a communication pipe 4 or an internal combustion type hot blast stove having the heat storing chamber 1 and the combustion chamber 2 in the same cylinder, when the operation of a shaft furnace to which said hot blast stove belongs is shut down, the hot blast stove is heated and heat insulated until the operation thereof is again started. In this case, because the silica brick 1 of the checker in the hot blast stove receives remarkable volumetric change when passes a transformation temp. of 575 deg.C and probably receives damage due to crack generation, the temp. of the lowermost part of the silica brick is set to 300-575 deg.C and the max. and min. temp. difference of the side surface in the stove is held to 400 deg.C or less. At the same time, the temp. difference between the under surface and the upper surface of the lowermost stage of the silica brick grid stacking part of the checker is held to 400 deg.C or less and the silica checker of the checker is prevented from being damaged by cracking due to expansion and contraction.
