Description
Technical field
The utility model relates to mineral hot furnace, particularly the electrode assembly of mineral hot furnace.
Background technology
The principle of electric arc furnaces 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 electric arc furnaces, mineral hot furnace and common electric arc furnaces 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.
Its three electrodes of current mineral hot furnace are arranged on electrode supporting platform a0 by electrode lifting device respectively, and be 120 jiaos of distributions, electrode lifting device comprises connection cover for seat a1, electrode holde cover a4, upper lower transmission mechanism a5, connecting cover for seat a1 is fixedly mounted in the installation circular hole on electrode supporting platform a0, the upper head plate a2 that connects cover for seat a1 is fixedly connected with electrode supporting platform a0 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, be connected and installed lower transmission mechanism a5 between axial with electrode holde cover a4l connecting cover for seat a1, hydraulic gear, drives electrode holde cover a4 and electrode in this way
a3move up and down, control electrode a3 inserts the degree of depth in body of heater.Three groups of electrodes
a3the upper circle distribution of electrode supporting platform a0 that is arranged on body of heater top is on utmost point heart circle at a concentric circles.
Its three electrodes of prior art
a3to be fixedly mounted on a utmost point heart circle above, three electrodes
a3can 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, is the core process parameter of mineral hot furnace.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.
Utility model content
