Pwodwi Deskripsyon

Pwosesis teknolojik Silisyòm pou itilizasyon chimik gen ladan preparasyon chaj founo, fusion founo elektrik, raffinage ak Distribisyon Silisyòm, ak kraze pou retire enklizyon salop. Tout matyè premyè yo dwe sibi tretman nesesè anvan chaj la prepare. Se silica a kraze nan ékrazan nan machwè jiskaske gwosè a nan moso yo pa plis pase 100mm, ak moso yo ki pi piti pase 5mm yo tès depistaj soti epi lave ak dlo. Paske fragman yo nan gwo fou a fonn nan pati siperyè gwo fou a, pèmeyabilite gaz la nan chaj la redwi, sa ki fè pwosesis pwodiksyon an difisil. Coke petwòl gen yon konduktiviti elektrik relativman wo, kidonk li dwe kase nan yon gwosè ki pa plis pase 10mm, ak kantite lajan an nan poud coke petwòl dwe kontwole. Paske li boule dirèkteman sou bouch founo a, li pral lakòz ensifizan ajan diminye.

 

Nan pwodiksyon an nan Silisyòm chimik, chabon bitumeu ka konplètman ranplase chabon, tankou Hunan Zhuzhou rafine chabon bitumeu, kabòn nan fiks rive nan 77.19 pousan, matyè a temèt se 19.4 pousan, kontni an sann se 3.41 pousan, kontni an Fe2O3 se {{8 }}.22 pousan, kontni Al2O3 a se 0.99 pousan, ak kontni an CaO se 0.17 pousan. . Dapre pratik pwodiksyon, li posib pou itilize sa a kalite chabon bitumeu pou fond Silisyòm chimik.

 

Blòk ak bato pou pwodiksyon Silisyòm pou itilizasyon chimik yo trete ak kouto bwa ak chippers bwa. Ajan rediksyon kabòn nan chaj founo a se sitou coke petwòl ak chabon bitumeu, ak kantite blòk bwa ak bato bwa depann sou kondisyon founo. Bwa pa itilize nan pwodiksyon, men bon jan kalite pwodwi a pi estab. Se rapò a nan chaj la detèmine dapre klas la nan pwodwi ki nesesè yo dwe pwodwi. Pwopòsyon coke petwòl ak chabon bitumineu detèmine dapre kantite kabòn ki nesesè pou chak pakèt Silisyòm minrè. Rapò a nan coke petwòl ak chabon bitumeu gen yon gwo enfliyans sou rezistans nan travay nan chaj la.

 

Apre yo fin peze chak eleman nan chaj la founo, chaj la melanje respire, epi apre yo fin gwo founo dife a, yo ajoute chaj la inifòm melanje nan gwo fou a. Kenbe yon sèten wotè sifas materyèl la ak manje respire.

 

Pwodiksyon chimik Silisyòm se kontinyèl. Kondisyon yo anndan fou a pa p'ap janm fini an tou. Pwodiksyon chimik Silisyòm se yon pwosesis kote enèji elektrik konvèti nan enèji chalè nan yon gwo fou elektrik, ak Lè sa a, enèji chalè a itilize dirèkteman chofe materyèl la pou pwodui yon reyaksyon chimik. Se poutèt sa, karakteristik elektrik yo nan gwo fou a trè enpòtan. Fonksyon an se fèmen-ark pou kenbe gwo founo tanperati a, amelyore efikasite tèmik la, ak amelyore pousantaj itilizasyon fou elektrik la. Nan rechèch la, yo itilize yon gwo founo Silisyòm metal ak yon kapasite de 3200KVA ak 6300KVA. Se SMELTING la te pote soti nan mitone pou yon sèten peryòd tan ak regilye manje konsantre. Anba sikonstans nòmal, li difisil pou chaj la koule otomatikman, epi li jeneralman nesesè pou fòse chaj la koule. Kondisyon founo a fasil pou fluctue e li difisil pou kontwole. Se poutèt sa, li nesesè jije kòrèkteman ak fè fas ak li nan tan nan pwodiksyon an. Se founo a tire chak 4 èdtan pou fwote ak depoze, epi salop la kase ak klase nan depo.

 

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.
