In the middle of rectifying, control refining furnace great Chi temperature, make to heat up in a steamer remaining zinc and be divided into therein three layers: upper strata is leaded zinc, is without cadmium zinc or B# zinc.
Principle of work of the present invention and working process are as follows:
The method that cadmia regeneration is produced into hot dip use zinc alloy of the present invention, the method comprises the following steps: the method is to utilize each intermetallic principle that vapour pressure there are differences at a certain temperature, after being removed, cadmia foreign metal obtains 0# zinc liquid, directly by chute, inject frequency cored induction furnace, allocate on demand appropriate aluminium into or binary or polynary zinc alloy for the hot dip of aluminium element Metal Production.
After the refining furnace that cadmia is 600～700 ℃ through temperature utilizes delayed heat melting, by insulation gauger, quantitatively inputting its chamber temperature is the rectifying tower rectifying of 1050～1250 ℃, the condenser condenses that zinc fume after evaporation is 600～880 ℃ through temperature becomes pure zinc liquid, directly input line-frequency induction cored electric furnace, casts alloy pig ingot through allocating into as required after aluminium element mixes; In rectifying tower, fail the zinc liquid of evaporation and take foreign metal and form and to slip remaining zinc and flow into refining furnace, the melting pool of refining furnace and treating pond temperature are respectively 600～650 ℃ and 550～600 ℃, through refining furnace, process the zinc oxidative slagging and the foreign metal that produce and discharged by cinder notch, the remaining zinc that slips mixes and returns to circulation with the zinc liquid of fusing after liquate purifies.
The heating of rectifying tower of the present invention, refining furnace, dispensing mechanism all adopts Sweet natural gas heat supply with insulation; Line frequency furnace adopts electric heat supply.
In fusing, no longer increase heat energy during cadmia, utilize and slip remaining zinc waste heat and melt liquate process; Heating value of natural gas is high, and burning-point is low, and required air quantity is large, therefore for traditional heat exchange chamber structure, improves, and waste heat is all concentrated for heat exchange air, has strengthened air input and the heat interchanging area of air simultaneously, takes full advantage of waste heat, energy-saving and emission-reduction; After the 0# zinc liquid of producing, can add direct fusion in line frequency furnace to produce the required metallic element of alloy, proportioning is produced pot galvanize alloy, has cancelled the process links that traditional employing master alloy is produced hot-dip galvanized alloy.
Cadmia production hot dip of the present invention is mainly comprised of refining furnace, rectifying tower, condenser, frequency cored induction furnace with the equipment of zinc, being linked as of technology chain: the zinc liquid that refining furnace fusing produces is connected with rectifying tower by insulation measuring apparatus, the top of container is connected with condenser by chute, and the 0# zinc liquid of condensation is connected with frequency cored induction furnace and is picked out finished product hot dip zinc by storage zinc pond; The bottom of the rectifying tower closed loop that is connected with refining furnace.Rectifying tower of the present invention is comprised of SiC section bar, is connected with Heat Room with combustion chamber, and air is sent into combustion chamber through Heat Room, and natural gas straight taps into into combustion chamber, and heating by the exhaust gases air is discharged by chimney; Refining furnace is comprised of melting pool and treating pond; Frequency cored induction furnace is power frequency electric furnace.
After the 0# zinc liquid of producing, can add direct fusion in line frequency furnace to produce the required metallic element of alloy, proportioning is produced pot galvanize alloy, has cancelled the process links that traditional employing master alloy is produced hot-dip galvanized alloy.For example the patent No. is that mono-kind of 200910094234.6 < < produces the combination metallurgical furnace of zinc alloy and the production combination method > > of zinc alloy needs a frequency cored induction furnace and at least two line frequency coreless induction furnaces to produce.
The patent No. is joining in cored electric furnace again and produce hot-dip galvanized alloy with line frequency coreless electric furnace production master alloy > > of proposing in 200910259545.3 < < hot-dip galvanized alloy production methods, and the smelting temperature of power frequency cored electric furnace carries out between (500～540 ℃).And in this patent, only utilize the frequency cored induction furnace can production hot dip zinc alloy, and smelting temperature is controlled at 460～480 ℃, the stirring body material of power frequency cored electric furnace is stainless steel, and zinc liquid temperature is lower, more can reduce the ferrous components of bringing into while stirring.By this method and not only reduced equipment investment, reduced the energy consumption of unit product, and do not caused segregation phenomena in application process.
The design of twice slagging-off operation of the present invention has the following advantages: 1, slagging-off efficiency is high; 2, safe; 3, be not easy to stop up, maintenance cost is low.
The liquid metal that plumbous tower fails to evaporate flows into liquating furnace through lower extending part, its waste heat energy effectively helps fusing newly to add cadmia raw material, after auxiliary Sweet natural gas melt raw material, waste residue floats over behind liquid metal surface, can once remove the gred, remove most of scum silica frost, through the liquid metal once removing the gred, handling to smelting furnace is incubated, and carries out secondary slagging-off, the cadmia purity of guaranteeing to enter tower tray between soak again, can effectively prevent that tower tray from stopping up, greatly reduce security incident and occur, and extend the work-ing life of plumbous tower, effectively reduce production costs.
In present device, exchanging hot cell transforms: lacked coal gas flue, specifically have the following advantages: because Zinc Factory of Huludao produces in 0# zinc process, adopt coal gas as energy medium, waste gas of combustion chamber utilizes waste gas residual heat to carry out preheating to entering air, the coal gas of combustion chamber at Heat Room in by Heat Room chimney discharge process, Heat Room cylinder brick owing to building by laying bricks or stones, duration of service etc. reason, make waste gas, coal gas, the damaged leakage of the airtight flue of air, cause explosion hazard.For this reason, the present invention draws above-mentioned security incident lesson, and transformation has been carried out redesigning in exchange hot cell, natural gas line is directly passed into combustion chamber internal combustion, no longer pass through this link of Heat Room preheating, effectively avoided the situation of natural gas leaking to occur, safety performance improves greatly.Since test is produced, there is not the situation of a cause leakage contribution safety in production, thoroughly solve potential safety hazard, guarantee to produce and carry out smoothly.
