Course development investigation and study and seek an opinion extensively, after be revised repeatedly, " condition of aluminous industry admittance " (the following abbreviation " condition " ) announced with announcement form by national development and reform committee. This is an important matter of countrywide aluminous industry, it is behavior of national standard investment, promote aluminous industry to health develops and realize the significant move of the energy-saving target that decrease a platoon continuously, also be one of measures that implement macroscopical adjusting control, in carry out carry out " condition " in the process, the aluminous industry of our country will accept an acid test. The standard invests behavior, raising admittance threshold is " condition " in reiterating key content. " condition " in be built clearly or change extend project to must abide by a country to concern a provision, declare by the program, must accord with layout of national industry policy, program, the procedures such as evaluation of mine of land commandeer, mine and exploration, environment is all ready and legal. Raise very clear and specific requirement to building dimensions, adoption technological process and equipment and specific technical economic norms. Build alumina project lowest to want to achieve 600 thousand tons for instance / year dimensions, use mineral separation to do obeisance to ear law or associated law craft, want to have the safeguard capacity of stock bauxite resource adequately at the same time. Electroanalysis to what transform aluminous enterprise must adopt 200kA above large bake beforehand groovy craft, strive in “ 915 ” evening electroanalysises aluminous industry uses 160kA above entirely large bake beforehand groovy smelt craft. In recent years, the country is right steely, cement, electroanalysis the industry of high-energy bad news such as aluminous, ferroalloy takes strict adjusting control, heavy fist hits out have repair. " condition " in sufficient body is revealed right energy-saving the demand that reduces a platoon. Build the law that do obeisance to ear to produce alumina for instance: Xiong of a surname summer seeks coal of mark of kilogram of?00 of box Yun Tuo / ton alumina, other technology under coal of 800 kilogram mark / ton alumina. Have technology of the law that do obeisance to ear must under coal of 520 kilogram mark / ton alumina, other technology under coal of 900 kilogram mark / ton alumina. Be opposite especially new transform electroanalysis aluminous productivity, communicate power consumption integratedly must under 14300 kilowatt hour / ton aluminous, voltaic efficiency must prep above 94% . Show some electroanalysising aluminous enterprise communicates power consumption integratedly to answer under 14450 kilowatt hour / ton aluminous, voltaic efficiency must prep above 93% , those who exceed target do not grant admittance. Pass technical reformation, energy-saving fall bad news, in “ 915 ” are achieved new transform level of industry specific power consumption. Should at the same time zincous effect coefficient is less than 0.08 times / groove? Day. Raised requirement of index of specific power consumption as much to aluminous treatment is built and having a company. For aluminous to electroanalysising enterprise, very relaxed Yi Da does not go to the requirement of index of specific power consumption, voltaic efficiency index and zincous effect coefficient, having an enterprise to have one share can be accomplished, but the company difficulty with promising not little number is greater. Statistical data made clear 2006, the whole nation electroanalysises power consumption of aluminous average communication 14697.23 kilowatt hour / ton aluminous, than " condition " in the 14450 kilowatt hour of the requirement / ton aluminous tower above 247.23 kilowatt hour / ton aluminous, in 63 enterprises of statistic, integrated communication power consumption is achieved and under average index have 27, occupy 42.9% , and achieve " condition " of the requirement have 16 companies only, occupy 25.4% . The problem that voltaic efficiency exists is more, in the meantime, is zincous effect coefficient in generally 0.2 times / groove? Or so days, prep above asks index is very much. Be apart from the time that 915 ” end still does not have “ now, the existing business that obtains admittance condition in these 4 years of time must give greater effort, include capital investment, Training Within Industry, level of management rise etc. Also ask design and scientific research unit are right at the same time of existing enterprise transform the technical plan that should have effective. Should see, our country electroanalysises in last few years technical level improves aluminous industry very fast, already entered world advanced range, but its develop be the; technology level of advance gradually to rise, it is the; that be accumulated gradually in ceaseless exploration and abounds to the understanding of physical field the demand to choosing material is higher and higher at the same time, construction level also raises slowly, because this is inchoate,the project of construction and the project that the near future builds are existence difference, especially 300kA and above are large in last few years the index of specific power consumption that bakes reaction of each company place gives slot beforehand differs very big, the author ever had arrived a lot of electroanalysis aluminous enterprise, the situation that see and understands each are not identical, of technical condition choose, the control of groovy voltage, although groovy look is same, but difference is bigger, the reason is many sided. Should realise, although " condition " medium demand is higher, if can fall to real point, the manufacturing cost of the enterprise can be reduced considerably, because " condition " in use up to resource reach use integratedly have a regulation, be like: Above of?1% of mace of corrode of chapter of faint of small box of a surname of phosphor of of wholesale of ㄑ of of land ò a kind of reed, other technology reclaims integratedly rate achieve 90% above, new water is used up under 7 tons / ton alumina, electroanalysis aluminous production alumina is used up under 1920 kilogram / ton aluminous, bad news of zincous carbon plain and neat under 430 kilogram / ton aluminous, metal of aluminous treatment material is used up under 1025 kilogram / ton, all these index will be right reduce cost, raise economic benefits to have positive effect. Of course, of level of specific power consumption reduce have new progress every year. 1~10 month electroanalysises this year whole nation of aluminium communication power consumption is 14467 kilowatt hour on average / ton aluminous, than going up year end 14697.23 kilowatt hour / ton aluminium reduced 230 kilowatt hour / ton aluminous, achieve and have 26 under the enterprise of average, have 14 companies aluminous that day ingot communicates power consumption integratedly under 14300 kilowatt hour / ton aluminous. Average and integrated specific power consumption was alumina whole nation 2005 coal of 998.23 kilogram mark / ton alumina, fell 2006 coal of 802.33 kilogram mark / ton aluminous, predict average and integrated specific power consumption still will reduce countrywide alumina substantially 2007. Reducing a respect, the whole nation electroanalysises partly aluminous enterprise controls zincous effect, reduce PFC to discharge progress faster, henan saves 6 enterprises to be made in charge for the making of sth. , among them, an enterprise already signed an agreement with American MGM company, will be zincous effect coefficient achieved 0.008 times / day? Groove, basically accomplished work without effect. Aluminous company is opposite in litter of electrobath liner solid is harmless change processing experiment progress is very rapid, be about to popularize in company interior, these explain, should try hard only hardheaded go tackling key problem, energy-saving the goal that reduces a platoon can come true, achieve " condition " asks target is a likelihood. Carry out and carry out " condition " it is the serious problem that aluminous industry must face, hope scientific research designs unit and enterprise to act jointly as soon as possible, take active and significant step, to come true " condition " in the goal that the requirement achieves makes arduous efforts.
