Description
Technical field
The present invention relates to a kind of electrode shell, particularly a kind of electrode shell that is used for the hot stove of large ore.
Background technology
Electrode be in the electric furnace smelting as the material of conductor, under the situation of low-voltage, big electric current, work usually, therefore good electrical conductivity to be arranged.Material as electrode must have high melt point, otherwise can melt very soon, influences carrying out smoothly of ordinary production.Carbonaceous material is ideal electrode material, and the electrode that electric furnace uses has three kinds, i.e. carbon pole, graphite electrode and self-baking electrode.Carbon pole is with low-ash anthracite, carbon materialses such as metallurgical coke according to a certain percentage with granularity at a certain temperature, add that binding agent, pitch evenly stir, compression moulding, and then 1300 ℃ of roastings form; Graphite electrode is that carbon pole is calcined under 2000-2500 ℃ of high temperature and is transformed; Self-baking electrode is in the electrode shell that is welded into steel plate is packed electrode paste on electric furnace top, utilizes through the electric current joule's heat energy of electrode self and the radiant heat of stove to form through the fusing roasting.Electrode shell is the shell mould of the definite shape of making for electrode moulding, and electrode paste is under paste column pressure certain in electrode shell, roasting slowly in smelting process and conductive electrode charcoal piece with certain intensity and shape; Because moulding and calcining process have been saved in limit use, edge forming, limit roasting, manufacture craft is simple, and is cheap, is widely used in smelting the hot stove of gold mine.
At present, existing self-baking electrode electrode shell (Fig. 1) often adopts the 2-3mm steel plate, and it is high 1.5 meters to roll into cylinder, interior welds 250-350mm muscle sheet 8-12 sheet, and dashing on the muscle sheet has circular port (Fig. 2) or rectangular opening (Fig. 3).The manufacture method of above-mentioned electrode shell is sheet metal to be welded into suitable for reading more bigger than lower port diameter, causes a joint shell just to insert the connected mode of next joint shell (the about 20mm of internal diameter), with electrode shell firm welding and polishing on every side.Lower rib does not have connection can't connect yet on the electrode shell.This structure electrode shell shortcoming mainly contains: 1. the muscle sheet is many, and upper/lower electrode muscle sheet can't connect mutually, causes the continued access perpendicularity poor, and it is high to move relative rate of failure; 2. the muscle sheet is many, and the ferrous material that electrode shell uses is many, and cost is high relatively; 3. ferrous material is many, and it is many that electrode itself is brought in the product composition of iron into, suitable the smelting the strict product of iron tramp content control.
Summary of the invention
For addressing the above problem, the present invention provides the few electrode shell that is used for the hot stove of large ore of ferrous material that a kind of continued access perpendicularity is good, electrode shell uses.
The present invention is used for the electrode shell of the hot stove of large ore; Comprise the shell ring that links to each other successively, shell ring comprises the housing of tubular, and the inboard of said housing vertically is provided with the muscle sheet of some equidistant placement; Wherein: said muscle sheet fixedly forms by two steel plates are folded mutually; Be provided with some circular ports between two steel plates, the upper end of two steel plates is provided with fork, the muscle sheet lower ends of the shell ring of said fork and its shell ring upper end, place; The inboard, two ends up and down of said housing is fixed with retainer ring respectively, and the said retainer ring outside between adjacent two shell rings is fixed with connecting ring.
The present invention is used for the electrode shell of the hot stove of large ore, and wherein: the inboard of said housing is provided with the muscle sheet of four equidistant placement.
The present invention is used for the electrode shell of the hot stove of large ore, and wherein: the material of said housing is the deoxidation low carbon steel plate.
The present invention is used for the electrode shell of the hot stove of large ore, and wherein: the thickness of said housing is 3mm.
The electrode shell that the present invention is used for the hot stove of large ore can connect mutually owing to upper/lower electrode muscle sheet, so the continued access perpendicularity is good.The electrode shell that the present invention is used for the hot stove of large ore through the some circular ports between two steel plates of said muscle sheet increased between electrode shell and the electrode paste in connect intensity, contact area and conductive effect; Therefore can reduce the quantity and the width of muscle sheet, reduce the ferrous material consumption.Because the muscle sheet is prone to form crackle or vestibule behind the electrode sintering; Reduce the muscle sheet and also just reduced crackle or the vestibule that sinters in the electrode; The good integrity of electrode, thus the ability that electrode bears electric current increased, and in use reduced contaminating impurity to product.
