Abstract
An ore-smelting arc furnace graphite contact shoe assembly comprises a hydraulic connecting device, an aqueous envelope and a graphite electrode, wherein the hydraulic connecting device is arranged at the external part of the left side of the aqueous envelope; the inner side of the aqueous envelope is provided with two graphite electrodes; each graphite electrode is formed from a graphite electrode contact shoe, upper cover water boxes, a steel contact shoe water box, insulated lifting lugs and a copper pipe jacket; the outer side of the graphite electrode contact shoe is provided with the steel contact shoe water box; the tops of the graphite electrode contact shoe and the steel contact shoe water box are provided with the upper cover water boxes; the tops of the upper cover water boxes are provided with the insulated lifting lugs; and the periphery of the steel contact shoe water box is provided with the copper pipe jacket. The ore-smelting arc furnace graphite contact shoe assembly has the characteristics of low failure rate, easy maintenance, power cut not caused easily in the furnace, no arc strike on productive part, and no need of replacing spare electrode contact shoe within twelve months of work.
Description
Technical field: a kind of ore deposit thermic arc stove graphite tile assembly belongs to smelting equipment.
Background technology: more than the present domestic metallic silicon arc furnace 6300KVA, generally adopt brasses.Brasses price height, and brasses is yielding under hot environment, and easily generation is beaten the arc phenomenon and is damaged brasses.Brasses water cooling simultaneously is not in place, and oxidation resistance is poor, is prone to fracture, cause in the stove to have a power failure, and easy-maintaining not.
The utility model content: the purpose of this utility model is a kind of saving manufacturing cost of invention, and is simple in structure, failure rate is low, a kind of ore deposit thermic arc stove graphite tile assembly of easy-maintaining.
A kind of ore deposit thermic arc stove graphite tile assembly is made up of hydraulic connecting device, hydrosphere and graphite electrode, and hydrosphere push rod screw is positioned at the hydrosphere left hand external, and there are two graphite electrodes the hydrosphere inboard.
Because adopt graphite tile to replace brasses to make electrode, conducting position can not beaten arc, failure rate is low, uses and need not change standby watt in 12 months.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 is hydraulic connecting device, and 2 is hydrosphere, and 3 is graphite electrode watt, and 4 is the loam cake water tank, and 5 is steel watt water tank, and 6 are the insulation hanger, and 7 is the copper pipe cover, and 8 is graphite electrode.
