Izinyathelo zokwelula impilo yokuguqula

1. Shintsha indlela yokwakha futhi uthuthukise inqubo ejwayelekile:

1.1 Ngaphansi kwezimo ezijwayelekile, izitini ezimanzi zizoveza umswakama, ongahambisani nokushisa emzimbeni njalo ku-400 ° C. Isakhiwo sokuguqula sisebenzisa inhlanganisela yokwakhiwa kwamatshe owomile namanzi, okungukuthi, izingqimba ezingenhla nezingezansi zendawo ye-tuyere nendawo yomlomo wesithando ngamatshe amnyama, kanti amanye angamatshe owomile.

1.2 Ukwakhiwa kwezitini ze-tuyere kushintshiwe kusuka kolunye uhlangothi kuya maphakathi kuya emaphethelweni amabili ukugwema amalunga angunxantathu nokususwa kwezitini ezihlanganisiwe ze-tuyere.

1.3 Izitini ze-arch eziphikisiwe zemilomo yesithando esingaphezulu nesingezansi zibekwa ngokulingana kusuka kolunye uhlangothi kuya emaphethelweni amabili ukusuka enkabeni kuye emaphethelweni amabili ukusiza ukukhiywa kwezinhlangothi zombili nokuvikela ukuthi izitini ezimbili zingawi ngenxa yokungalingani nokungaphelele izikhala.

1.4 Ukusatshalaliswa kwamalunga esitini kugcwele, kufana, kuyafana ngaphakathi nangaphandle, futhi amalunga wokunweba kufanele ahlangabezane nezidingo ze-2-3mm. Amalunga wezitho zezitini kuzo zonke izingxenye kufanele akhiywe. Umzimba wezitini ocutshunguliwe awungeqi ngaphezu kwengxenye eyodwa kwezintathu, futhi umzimba wezitini ocutshunguliwe awuzukuba ngaphansi kwezingxenye ezimbili kwezintathu.

1.5 mg filler kufanele ikhuhlwe futhi ihlakazeke ngesandla lapho iwa ukusuka ekuphakameni kwemitha elilodwa. Ubukhulu nokuqina kokugcwalisa kufanele kufane.

1.6 Ungasebenzisi izitini ze-chrome-magnesium ezilimele, eziminyene nezimanzi.

2. Lawula izinto ezibandayo zokuguqula izinto ukuvimbela ukugqwala okushisa okuphezulu

Ukuhlolwa kukhombisa ukuthi lapho isitini se-chrome-magnesia sinokumelana nokushaqeka okungashisi ngo-850 ℃, sizophuka amahlandla ayi-18, okuzolimaza ulwelwesi lwesithando somlilo. Ngakho-ke, kuyadingeka ukugwema ukushintshashintsha kwezinga lokushisa kwesithando somlilo, ukunciphisa nokuqeda ukulimala kwengcindezi eshisayo kulwelwesi lwesithando. Ekukhiqizweni, izinga lokushisa kwesithando lizinzile ngokulawula inani lokushaja okubandayo.

3. Lawula ngokunengqondo okuqukethwe kwe-silicon ye-converter slag ukunciphisa ukugqwala kwamakhemikhali

I-slag engathathi hlangothi noma ebuthakathaka ingavikela ulwelwesi lwesithando somlilo. I-Olivine magnesia inomphumela omubi wokulimaza. Ayikwazi nje ukuncibilikisa ubuso be-magnesia refractories, kepha futhi ingangena ngaphakathi kwezingqinamba ze-magnesia ukuze incibilike.

Ukuphakama kwamazinga okushisa, kukwanda kokuncibilika kwe-MgO ku-converter slag, nokwakhiwa kwe-forsterite enezinga lokushisa eliphansi lokuthambisa ngaphansi komthwalo wokushisa okuphezulu, okwehlisa ukusebenza kwezitini zemagnesia. I-iron oxide nayo ingagcwalisa izinhlayiya ze-periclase kanye ne-chromite, okudala ukulimala kwezinhlayiyana nokulimala ngokushesha kwezitini zemagnesia. Okuqukethwe kwe-silicon kwe-slag yokuguqula kungaphansi kuka-18%, okuyi-alkaline, futhi okuqukethwe kwe-silicon ye-converter slag kungaphezu kuka-28%, oku-asidi. Okuqukethwe kwe-silicon ku-slag yokuguqula kuphakathi kuka-19% no-24%, ongathathi hlangothi noma one-alkaline ebuthakathaka, futhi awunakonakala entanjeni yezitini zemagnesia. Lawula ngokuqinile okuqukethwe kwe-silicon ye-converter slag ngesikhathi sokukhiqizwa ukusimamise phakathi kuka-19% no-24%.

4. Ukwenza ngcono ikhwalithi yabasebenzi

Thuthukisa ikhwalithi kanye nokukwazi ukukhiqizwa kwesithando somlilo, ukusebenza kwesiguquli kanye nabasebenzi bokuphathwa kokukhiqiza ukuqinisekisa ikhwalithi yokukhiqizwa kwesithando somlilo.

Thuthukisa amakhono okuphendula okuphuthumayo, ukwenganyelwa nokuphathwa kokukhiqizwa kwesayensi nokuqinile.

5. Ukukhetha okunengqondo kokuqina komoya nokuhlungwa komoya-mpilo

Enqubeni yokukhiqiza, ukungafani phakathi kwesithando somlilo nomlandeli akunakugwenywa. Akuvunyelwe neze ukusebenzisa ifeni ukuphakela umoya emzimbeni omncane wesithando ukuvimbela ukuguguleka okukhulu nokuncibilika okukhulu endaweni yase-tuyere. Ukuhlungwa kokunothiswa komoya-mpilo kwesiguquli akufanele kube ngaphezu kuka-27%, ukuhlushwa kwe-oxygen kufanele kube ngaphezu kuka-27%, futhi ulwelwesi lwezitini kufanele lugezwe kakhulu.
