摘要:
An object of the present invention is to provide a taphole cooling structure allowing to prevent the wear and deformation of peripheral bricks of a taphole for taking out solutions from a furnace body, and to maintain a stable operation of the furnace in a high copper matte grade operation and high-load operation.Means for Solving the ProblemsTo provide a structure for cooling a taphole provided with a hollow jacket body to be inserted into an opening penetrated on a furnace wall, wherein a water passage is installed in the internal of the said jacket body for circulating cooling water while a flange made of the same material as the above furnace wall is provided on the periphery of the said jacket body to be weldingly connected to the said furnace wall, wherein a refractory material is filled within a hollow of the said hollow jacket body and perforated with a taphole for draining the solutions from the furnace body.

An operation method of a flash smelting furnace includes blowing a gas for dispersing raw material and contributing to a reaction, from a lance at an upper portion of a shaft so that the gas forms a spiral flow. A raw material supply apparatus includes a supply portion supplying raw material and a gas for dispersing the raw material and contributing to a reaction into a flash smelting furnace, wherein the supply portion has a lance provided at an upper portion of a shaft that blows the gas so that the gas forms a spiral flow.
