Description
Technical field
The utility model relates to mineral hot furnace, particularly the electrode assembly of mineral hot furnace.As the electrodes in mine hot stove device for material smelting (melting) refinings such as titanium slag, chromium oxide, calcium carbides.
Background technology
The principle of arc furnace is to utilize the high temperature of electric arc between electrode to come melting ore and metal, mineral hot furnace belongs to a kind of of arc furnace, mineral hot furnace and common arc furnace difference be, mineral hot furnace utilizes two kinds of modes that high arc temperature and electric current generate heat by furnace charge to come melting ore and metal.
It is that electrode holder b0 is upper that its three electrode a3 of current mineral hot furnace are arranged on by electrode lifting device respectively, and three electrode Cheng120 angles distribute, and three groups of electrode a3 circle distribution are on utmost point heart circle at a concentric circles;
Electrode lifting device is the sliding gib b3 being slidably installed on bracing frame b0 column b1, the transmission fluid cylinder pressure b4 being connected between sliding gib b3 and bracing frame b0 crossbeam b2 forms, electrode a3 is fixedly mounted on sliding gib b3 front end, and with sliding gib, b3 moves up and down.
Or electrode lifting device is mounted in counterweight c1 and steel rope reel c3, pulley c2 on bracing frame b0 crossbeam b2 in bracing frame b0 column b1, is connected to the boom hoisting that the steel wire rope c4 on sliding gib b3 leading section forms, electrode a3 is fixedly mounted on sliding gib b3 front end, and with sliding gib, b3 moves up and down.
Or electrode lifting device is to consist of connection cover for seat a1, electrode holde cover a4, transmission fluid cylinder pressure a5, connecting cover for seat a1 is fixedly mounted in the installation circular hole on electrode holder b0, the upper head plate a2 that connects cover for seat a1 is fixedly connected with electrode holder b0 surface bolt, electrode
a3be inserted in electrode holde cover a4 and with electrode holde cover a4 and be fixedly connected with, electrode holde cover a4 be connected cover for seat a1 endoporus and be slidably matched, connect cover for seat a1 and electrode holde cover a4 axially between connection transmission fluid cylinder pressure a5, drive electrode holde to overlap a4 and electrode
a3move up and down.
Its three electrode a3 of prior art are fixedly mounted on a utmost point heart circle above, and three electrode a3 can not move radially in the plane and regulate utmost point heart circle size.
The utmost point heart circle of electrodes in mine hot stove i.e. the size of the circle at three electrode centers places, and upper and lower rising or falling speed in production process, it is the core process parameter of mineral hot furnace, in smelting (melting) refining, keeping the relatively stable of three interelectrode input currents is the most important condition that mineral hot furnace is produced, after the utmost point heart circle size of electrode is determined, the main production parameter of stove is determined.The mineral hot furnace of smelting (melting) refining different materials and finished product, its electrode utmost point heart circle is different, such as furnace of calcium carbide, ferronickel stove, titanium slag stove, chromium oxide stove etc.Aborning, the utmost point heart of electrode circle size all plays conclusive impact to output and the quality of the performance of mineral hot furnace, smelting (melting) refining product.While producing a lot of product such as titanium slag, chromium oxide, because solid phase, the liquid phase conducting rate difference of these products materials are larger, electrode utmost point heart circle size preferably can change with the solid phase of furnace charge, the variation of amount of liquid phase ratio.
Because transformer efficiency is certain, the voltage of output is fixed, and electrode utmost point heart circle is immutable, so when solid phase, the larger raw materials of liquid phase conducting rate difference such as mineral hot furnace smelting (melting) refining titanium slag, chromium oxide, in earlier stage because raw material is solid phase, conductance is very low, electric current is very little, and smelting (melting) refining is very slow, has a strong impact on output, increase and produce power consumption, the later stage, while being liquid phase because of raw material, conductance was very high, electric current is very large, transformer seriously overloads, and gently causes breaking impact to produce, heavy burn transformer.
In smelting (melting) refining process, because stove Raw can not be fused into liquid phase by solid phase as early as possible, first the raw material of fusing is long the duration of heat, and the chemical composition in material can cause segregation, has a strong impact on product quality.Because stove Raw can not be fused into liquid phase by solid phase as early as possible, the material that also easily occurs collapsing, spatter material, the accident such as cause that personnel scald.
If the circle design of the utmost point heart is bigger than normal, while starting to produce, between electrode, does not produce electric arc, need to add striking material at the bottom of a large amount of auxiliary furnaces, not only increase production cost, and also scaling loss bottom refractory, increase mineral hot furnace outage rate.If the design of utmost point heart circle is less than normal, although easily produce electric arc while starting to produce between electrode, do not need to add striking material at the bottom of a large amount of auxiliary furnaces, due to electrode and furnace side wall spacing excessive, there will be because not being melted " raw material " of smelting, can have a strong impact on product yield, quality.
