METHOD FOR CONSTRUCTING BRICKS OF MIXED COOLING CHAMBER AND CONNECTION PIPE OF HOT STOVE IN BLAST FURNACE

摘要

PURPOSE: A method for constructing bricks of a mixed cooling chamber and a connection pipe of a hot stove in a blast furnace is provided which prevents red heat and cracking of a connection pipe and an iron skin per each furnace of the hot stove, and prevents falling and collapse accidents due to the expansion difference of bricks. CONSTITUTION: The method for constructing bricks of a mixed cooling chamber and a connection pipe (116) of a hot stove in a blast furnace is characterized in that a reinforcement device (50) for supporting wall bricks (156) is mounted on the middle part of the mixed cooling chamber (120), and the reinforcement device is arranged so that the middle part of the mixed cooling chamber is surrounded in the circumferential direction, wherein wall bricks in the upper side are constructed so that they are strongly supported, thereby not being fallen off downwardly.
