Deskrizzjoni tal-Prodotti

Il-proċess teknoloġiku tas-silikon għall-użu kimiku jinkludi preparazzjoni ta 'ċarġ tal-forn, tidwib tal-forn elettriku, raffinar u ikkastjar tas-silikon, u tgħaffiġ għat-tneħħija tal-inklużjonijiet tal-gagazza. Il-materja prima kollha għandha tgħaddi minn trattament meħtieġ qabel ma titħejja l-ħlas. Is-silika hija mgħaffeġ fil-crusher tax-xedaq sakemm id-daqs tal-biċċiet ma jkunx aktar minn 100mm, u l-biċċiet iżgħar minn 5mm jiġu skrinjati u maħsula bl-ilma. Minħabba li l-frammenti fil-forn huma mdewba fil-parti ta 'fuq tal-forn, il-permeabilità tal-gass tal-ħlas titnaqqas, u tagħmel il-proċess ta' produzzjoni diffiċli. Il-kokk tal-pitrolju għandu konduttività elettrika relattivament għolja, għalhekk għandu jinqasam għal daqs ta 'mhux aktar minn 10mm, u l-ammont ta' trab tal-kokk tal-pitrolju għandu jiġi kkontrollat. Minħabba li jinħaraq direttament fuq il-ħalq tal-forn, se jikkawża aġent li jnaqqas insuffiċjenti.

 

Fil-produzzjoni tas-silikon kimiku, il-faħam bituminuż jista 'jissostitwixxi kompletament il-faħam tal-kannol, bħall-faħam bituminuż raffinat Hunan Zhuzhou, il-karbonju fiss jilħaq 77.19 fil-mija, il-materja volatili hija 19.4 fil-mija, il-kontenut tal-irmied huwa 3.41 fil-mija, il-kontenut ta' Fe2O3 huwa {{8 }}.22 fil-mija, il-kontenut ta' Al2O3 huwa 0.99 fil-mija, u l-kontenut ta' CaO huwa 0.17 fil-mija. . Skont il-prattika tal-produzzjoni, huwa fattibbli li tuża dan it-tip ta 'faħam bituminuż biex tidwib is-silikon kimiku.

 

Blokki u ċipep għall-produzzjoni tas-silikon għall-użu kimiku huma pproċessati bi qtugħ tal-injam u ċipep tal-injam. L-aġent li jnaqqas il-karbonju fil-ħlas tal-forn huwa prinċipalment kokk tal-pitrolju u faħam bituminuż, u l-ammont ta 'blokki tal-injam u laqx tal-injam jiddependi fuq il-kundizzjonijiet tal-forn. L-injam ma jintużax fil-produzzjoni, iżda l-kwalità tal-prodott hija aktar stabbli. Il-proporzjon tal-ħlas huwa determinat skond il-grad tal-prodott meħtieġ li jiġi prodott. Il-proporzjon ta 'kokk taż-żejt u faħam bituminuż huwa determinat skond l-ammont ta' karbonju meħtieġ għal kull lott ta 'silikon minerali. Il-proporzjon tal-kokk taż-żejt u l-faħam bituminuż għandu influwenza kbira fuq ir-reżistenza tax-xogħol tal-ħlas.

 

Wara li kull komponent tal-ħlas tal-forn jintiżen, il-ħlas jitħallat b'mod uniformi, u wara li l-forn jitħabbat, il-ħlas imħallat b'mod uniformi jiżdied mal-forn. Żomm ċertu għoli tal-wiċċ tal-materjal u għalf indaqs.

 

Il-produzzjoni tas-silikon kimika hija kontinwa. Il-kundizzjonijiet ġewwa l-forn mhumiex dejjiema lanqas. Il-produzzjoni tas-silikon kimika hija proċess li fih l-enerġija elettrika tiġi kkonvertita f'enerġija tas-sħana f'forn elettriku, u mbagħad l-enerġija tas-sħana tintuża biex issaħħan direttament il-materjal biex tipproduċi reazzjoni kimika. Għalhekk, il-karatteristiċi elettriċi fil-forn huma importanti ħafna. L-operazzjoni tat-tidwib hija b'ark magħluq biex iżżomm il-forn b'temperatura għolja, ittejjeb l-effiċjenza termali, u ttejjeb ir-rata ta 'utilizzazzjoni tal-forn elettriku. Fir-riċerka, jintuża forn tas-silikon tal-metall b'kapaċità ta '3200KVA u 6300KVA. It-tidwib jitwettaq billi ttektek għal ċertu perjodu ta 'żmien u għalf konċentrat regolari. Taħt ċirkostanzi normali, huwa diffiċli li l-ħlas jinżel awtomatikament, u ġeneralment huwa meħtieġ li l-ħlas jiġi mġiegħel jegħreq. Il-kundizzjoni tal-forn hija faċli biex tvarja u diffiċli biex tikkontrolla. Għalhekk, huwa meħtieġ li tiġġudika b'mod korrett u tittrattaha fil-ħin fil-produzzjoni. Il-forn jiġi sparat kull 4 sigħat għall-għorik u l-ikkastjar, u l-gagazza tinqasam u tinħażen.

 

Smelting process of silicon for chemical industry  The technological process of silicon for chemical use includes furnace charge preparation, electric furnace smelting, silicon refining and casting, and crushing for removing slag inclusions. All raw materials must undergo necessary treatment before the charge is prepared. The silica is crushed in the jaw crusher until the size of the pieces is not more than 100mm, and the pieces smaller than 5mm are screened out and washed with water. Because the fragments in the furnace are melted in the upper part of the furnace, the gas permeability of the charge is reduced, making the production process difficult. Petroleum coke has a relatively high electrical conductivity, so it must be broken to a size of no more than 10mm, and the amount of petroleum coke powder must be controlled. Because it burns directly on the furnace mouth, it will cause insufficient reducing agent.  In the production of chemical silicon, bituminous coal can completely replace charcoal, such as Hunan Zhuzhou refined bituminous coal, the fixed carbon reaches 77.19%, the volatile matter is 19.4%, the ash content is 3.41%, the Fe2O3 content is 0.22%, the Al2O3 content is 0.99%, and the CaO content is 0.17%. . According to production practice, it is feasible to use this kind of bituminous coal to smelt chemical silicon.  Blocks and chips for the production of silicon for chemical use are processed with timber cutters and wood chippers. The carbonaceous reducing agent in the furnace charge is mainly petroleum coke and bituminous coal, and the amount of wood blocks and wood chips depends on the furnace conditions. Wood is not used in production, but the product quality is more stable. The ratio of the charge is determined according to the grade of the product required to be produced. The proportion of petroleum coke and bituminous coal is determined according to the amount of carbon required for each batch of ore silicon. The ratio of petroleum coke and bituminous coal has a great influence on the working resistance of the charge.  After each component of the furnace charge is weighed, the charge is mixed evenly, and after the furnace is pounded, the uniformly mixed charge is added to the furnace. Keep a certain height of the material surface and feed evenly.  Chemical silicon production is continuous. The conditions inside the furnace are not eternal either. Chemical silicon production is a process in which electric energy is converted into heat energy in an electric furnace, and then the heat energy is used to directly heat the material to produce a chemical reaction. Therefore, the electrical characteristics in the furnace are very important. The smelting operation is closed-arc to maintain the high temperature furnace, improve the thermal efficiency, and improve the utilization rate of the electric furnace. In the research, a metal silicon furnace with a capacity of 3200KVA and 6300KVA is used. The smelting is carried out by simmering for a certain period of time and regular concentrated feeding. Under normal circumstances, it is difficult for the charge to sink automatically, and it is generally necessary to force the charge to sink. The furnace condition is easy to fluctuate and difficult to control. Therefore, it is necessary to judge correctly and deal with it in time in production. The furnace is fired every 4 hours for scouring and casting, and the slag is broken and sorted into storage.Smelting process of silicon for chemical industry  The technological process of silicon for chemical use includes furnace charge preparation, electric furnace smelting, silicon refining and casting, and crushing for removing slag inclusions.
