Abstract
The invention discloses a kind of method that lead liquid is purified using deslagging agent, by electric lead, lead bullion or lug lead raw material, it is put into boiler, 420 460 DEG C are warming up to after fusing, the ratio for adding 0.6 0.8 kilograms of deslagging agents according to 1 ton of lead has weighed deslagging agent and has uniformly been sprinkling upon lead liquid surface, it is stirred, the scum silica frost state of observation, if it was observed that scum silica frost gradually scatters, ash shape is become by pasty state, stops stirring after scum silica frost fades to khaki, and pick up ash shape scum silica frost, if scum silica frost does not separate not into khaki or not into ash shape, slag lead, stirring should be continued untill requirement is reached.Advantages of the present invention：Slag rate when slag ash quantity caused by the slag making of stokehold, the lead tolerance of slag ash and alloy product use is reduced, the comprehensive recovery of lead is improved, reduces the cost for repeating to smelt；With deslagging agent than with rosin slag making can it is few produce about 1.71% lead skim；Solves low temperature slag making, the problem of temperature is difficult to control, and slag making effect is unstable；There is no flue gas generation.
Description
Technical field
The present invention relates to a kind of method for purifying lead liquid, more particularly to a kind of method that lead liquid is purified using deslagging agent.
Background technology
Reacted during aluminium alloy smelting due to aluminium and water or with the oxygen in air, pernicious gas can be produced or solid particle is miscellaneous
Matter, such aluminium liquid can be produced when later stage deep processing is cast stomata, forge a knife, slag inclusion etc. one is class quality problems, so necessary
Refining cleaning procedure is carried out to aluminium liquid, existing technology is to add rosin in electric lead, lead bullion or lug lead to carry out stokehold slag making,
Rosin is added, substantial amounts of dense smoke can be produced during slag making, slag ash quantity, the lead tolerance of slag ash and alloy product use caused by slag making
When slag rate it is all higher, be unfavorable for the control of cost and the improvement of quality.Rosin is substituted using deslagging agent now and carries out stokehold
Slag making, to reduce slag rate when slag ash quantity caused by the slag making of stokehold, the lead tolerance of slag ash and alloy product use, so as to improve
The comprehensive recovery of lead, the cost for repeating to smelt is reduced, can also mitigate labor strength.
The content of the invention
The technical problem to be solved in the present invention, it is to provide a kind of method for purifying lead liquid using deslagging agent, lead can be improved
Comprehensive recovery, reduce repeat smelt cost, can also mitigate labor strength.
The present invention is realized by following proposal：It is a kind of using deslagging agent purify lead liquid method, its be used for electric lead, lead bullion and
Lug lead is cleaned, and it is followed the steps below：
Step 1：By electric lead, lead bullion or lug lead raw material, it is put into boiler, 420-460 DEG C is warming up to after fusing；
Step 2：The ratio that 0.6-0.8 kilograms of deslagging agent is added according to 1 ton of lead has weighed deslagging agent；
Step 3：The load weighted deslagging agent of step 2 is uniformly sprinkling upon the lead liquid surface after step 1 fusing, keeping temperature is stable
At 420-460 DEG C；
Step 4：Mixer is added in the boiler of step 3, start mixer and be stirred；
Step 5：Scum silica frost state in observation of steps four, if it was observed that scum silica frost gradually scatters, ash shape is become by pasty state, works as scum silica frost
Fade to and stop stirring after khaki, and pick up ash shape scum silica frost, if scum silica frost not into khaki or not into ash shape, slag lead regardless of
From, should continue stirring untill requirement is reached；
Step 6：After the ash shape scum silica frost of step 5 drags for the greatest extent, into next step smelting process.
The temperature of the boiler controls at 420-460 DEG C all the time.
The electric lead, lead bullion or the ratio of lug lead raw material and deslagging agent are 1:0.0006-0.0008.
The mixing time of the mixer is 20-30 minutes.
The mixing time of the mixer by scum silica frost Determines.
Beneficial effects of the present invention are：
1st, a kind of method that lead liquid is purified using deslagging agent of the present invention substitutes rosin progress stokehold slag making using deslagging agent, to reduce
Slag rate when slag ash quantity, the lead tolerance of slag ash and alloy product use caused by the slag making of stokehold, is returned so as to improve the synthesis of lead
Yield, the cost for repeating to smelt is reduced, can also mitigate labor strength；
2nd, the present invention it is a kind of using deslagging agent purify the method for lead liquid by the Adding Way of deslagging agent, add temperature, addition,
By the experiment of new technology, with deslagging agent than few can be produced with rosin slag making about 1.71% lead skim, use slagging tap for rosin slag making
Rate is 2.67%, and is 0.96% with the slag yield of deslagging agent, and the lead calcium product of each 40 tons of pots can pull nearly 690 kilograms of lead skim out less
Slag；
3rd, a kind of method for purifying lead liquid using deslagging agent of the present invention solves low temperature slag making, and temperature is difficult to control, slag making effect
The problem of unstable；
4th, a kind of method for purifying lead liquid using deslagging agent of the present invention does not have flue gas generation, and pollution, protection will not be produced to environment
The health of environment and operating personnel.
