A method of constructing a blast furnace body, by dismantling and assembling said blast furnace body in a shortened period of time and at reduced cost, wherein said blast furnace body is divided into a top section, a hearth section and a plurality of intervening furnace-body ring block sections,
- said method comprising the steps of:
- connecting a foundation of said blast furnace body to a furnace-body carriage car having a loading level substantially aligned with said foundation of said blast furnace body,
- moving each of said furnace-body ring blocks between said foundation and said furnace-body carriage car;
- and
- moving by a lifting transfer apparatus each of said furnace-body ring blocks between said furnace-body carriage car and a furnace-body assembly position, wherein said lifting transfer apparatus is movable.
A lifting transfer apparatus for lifting and transferring each of a plurality of furnace-body ring blocks obtained by dividing a blast furnace body into a top section, a hearth section and intervening sections,
- said lifting transfer apparatus comprising a support for a plurality of lifting jacks, wherein said support has a movable body, and means for moving said lifting transfer apparatus.
A lifting transfer apparatus for lifting and transferring each of a plurality of furnace-body ring blocks obtained by dividing a blast furnace body into a top section, a hearth section and intervening sections when said blast furnace body is dismantled or assembled,
- said lifting transfer apparatus including a lifting mechanism, wherein said lifting mechanism is movable relative to said furnace-body ring blocks.
A lifting transfer apparatus for lifting and transferring each of a plurality of furnace-body ring blocks obtained by dividing a blast furnace body, including a top section, intervening sections and a hearth section in order to dismantle and assemble the blast furnace,
- said lifting transfer apparatus comprising a movable support and a movable lifting mechanism.
