Abstract
The invention relates to a blast furnace. The blast furnace comprises a furnace body and a fire-spraying nozzle which is arranged on the furnace body and used for heating furnace charges in the furnace body, wherein a repair device capable of repairing any positions of an inner liner of the furnace body is arranged in the furnace body and comprises a gunning machine, wherein a rotatable spraying pipe is arranged at the gunning machine and is connected with a spraying head which is communicated with the spraying pipe and can face to the inner liner in a rotating manner. The gunning machine provided with the rotatable spraying pipe and the rotatory spraying head is arranged in the furnace body, so that paints can be automatically sprayed onto the inner liner of the furnace body so as to repair the inner liner, namely, the operation is convenient; and the operation that the inner liner is reconstructed in a brick laying manner is not required. Thus, the working intensity of a worker is lightened; the high maintenance cost is saved; and the production cost is decreased.
