Abstract
The utility model provides a pressure ring for an ore-smelting furnace with a novel structure, which comprises: a pressure ring body which is a hollow box body; a corrugated expansion tank mounting hole disposed in the pressure ring body; and a connecting pin shaft hole disposed at one side of the pressure ring body. The pressure ring for the ore-smelting furnace has high mechanical strength, and has good overall watertightness and heat-conducting property, will not form magnetic vortex, and has low reactive loss and long service life.
Description
Technical field
The utility model relates to the device of controlling that a kind of ore-smelting electric furnace uses, and relates in particular to the pressure rings of controlling device.
Background technology
Pressure rings is the important component part of ore-smelting electric furnace electrode holde, its effect is to be used for installing bellow expander or hydraulic jack, pressure rings and ripple literary composition expander are formed electrode holde jointly, on electrode, give electrode with assurance with powerful current delivery with electrodes conduct brasses radial compaction.
Electrode holde is a lot of with the device form that brasses compresses electrode, at present the taper ring type that pneumatic disk spring type, oil cylinder transmission are arranged, hydraulic pressure rubber pattern and bellows--the pressure ring type etc. that adopt both at home and abroad.In China, especially on large-scale electric furnace more employing be that expansion tube--the pressure ring type is controlled device for ripple literary composition, its advantage is that the ripple literary composition expansion tube of radial arrangement is corresponding with electrodes conduct brasses number, radially hold out against brasses one to one, be not subjected to the electrode shell deformation effect, can guarantee that brasses closely contacts with electrode, the reason contact is not bad, generation is beaten arc and is caused electrode accident or damage brasses between electrode and brasses, thereby influences the ordinary production of electric furnace.Adopt the pressure ring type to control useful life that device makes brasses, greatly reduce production cost by prolonging present 8 years original half a year.Its shortcoming is that the present pressure rings that adopts is steel plate and is welded, owing to be to work in the hot environment more than 600 ℃, must water flowing cool off.After operation a period of time, steel plate oxidation or weld cracking can occur and cause pressure rings to be leaked, must blowing out reparation, the pressure rings of some material is to be difficult to repair and to go out of use.So both influence the ordinary production of electric furnace, increased the production cost of electric furnace again.
Summary of the invention
At the defective that prior art exists, the utility model provides a kind of cast type pressure rings of new structure, and it comprises the pressure rings body, and the pressure rings body is a hollow box body; Ripple expansion tank installing hole is arranged in the pressure rings body; The connecting pin axis hole is arranged on a side of pressure rings body.
The pressure rings body is the ZcuAl8Mn13Fe3 non-ferrous metal, logical cooling water in the pressure rings body.
Also be provided with reinforcement in the hollow box body.
Casing one side is provided with cooling water inlet pipe and cooling water outlet pipe.
The casing Holder for hanging household utensiles is set between cooling water inlet pipe and the cooling water outlet pipe.
The other side of casing is provided with bottom guard ring Holder for hanging household utensiles.
Described pressure rings body is combined by a plurality of split bodies.
The structure of the pressure rings that the utility model proposes is a middle empty class watt shape, logical cooling water in the empty stomach, and two ends are the whole connecting pin axis hole that casts out, and end face is cast with the suspension rod Connection Block, and inlet tube and outlet tube has following effect:
Adopt high-strength casting to replace non-magnetic rustproof steel plate Welding Structure with non-ferrous metal or magnetism-free stainless steel monoblock cast structure, the overall performance of equipment is good, because no weld seam moves in hot environment for a long time and can not leak because of weld cracking;
Pressure rings distinguish combination, the corresponding lobe pressure rings of per two blocks of brasses, when needing to change pressure rings, a lobe that has only needed to change bad does not need integral replacing, can reduce production costs and the spare part expense.
Interchangeability is good, and each lobe one power ring structure is all the same with profile, can be standby each other.
Description of drawings
The vertical view of Fig. 1 the utility model pressure rings;
Fig. 2 is the A--A profile.
Embodiment
Shown in seeing figures.1.and.2, be respectively the vertical view and the A--A profile of pressure rings of the present utility model.Shown in above-mentioned accompanying drawing, the utility model pressure rings body 1 is a hollow box body, and it is the non-ferrous metal monoblock cast of ZcuAl8Mn13Fe3 by material, logical cooling water in the pressure rings body 1, casing wall thickness 15mm; Ripple expansion tank installing hole 2 is arranged in the pressure rings body 1; Connecting pin axis hole 3 is arranged on a side of pressure rings body; Also be provided with reinforcement 4 in the hollow box body 1, not only play casing and add effect, but double as water route dividing plate also; Casing one side is provided with cooling water inlet pipe 5 and cooling water outlet pipe 7, and above-mentioned two pipes are the 1Cr18Ni9Ti gapless stainless steel tube, with the casing founding be one; Between cooling water inlet pipe 5 and the cooling water outlet pipe 7 casing Holder for hanging household utensiles 6 is set; The other side of casing is provided with bottom guard ring Holder for hanging household utensiles.Whole after hydraulic pressure (pressure that tries the water is 1Mpa) pass the test, blasting treatment is carried out on the surface.
Because the capacity difference of the hot stove in ore deposit, the diameter of electrode are also different, just there are the pressure rings of different overall dimensions and electrode to be complementary.Drawing provided by the utility model is that ∮ 1380 electrodes design with the diameter.
The pressure rings mechanical strength of making by the design is big, and whole watertightness and good heat conductivity can not form the magnetic eddy current, and reactive loss is little, long service life.
