Amanyathelo okwandisa ubomi bokuguqula

1. Guqula indlela yokwakha kwaye uphucule umgangatho womgangatho:

1.1 Phantsi kweemeko eziqhelekileyo, izitena ezimanzi ziya kuvelisa ukufuma, okungakulungeliyo ukomisa iqondo lobushushu rhoqo ku-400 ° C. I-masonry yokuguqula yamkela indibaniselwano yokwakha eyomileyo kunye nolwakhiwo olumanzi, oko kukuthi, amanqanaba aphezulu kunye asezantsi endawo ye-tuyere kunye nomlomo womlilo yindawo emanzi, kwaye yonke eminye yomejo owomileyo.

1.2 Ukwakhiwa kwezitena ze-tuyere kutshintshiwe ukusuka kwelinye icala ukuya embindini ukuya kwiziphelo ezibini ukunqanda ukudibana konxantathu kunye nokususwa kwezitena ezidityanisiweyo.

I-1.3 Izitena ze-arch eziguqulweyo zemilomo yomlilo ephezulu kunye nezantsi zibekwa ngokulinganayo ukusuka kwelinye icala ukuya kwiincam ezimbini ukusuka embindini ukuya kwiziphelo ezibini ukulungiselela ukuvaleka kwamacala omabini nokukhusela izitena zombini zingawi ngenxa yokungalingani nokungafezeki izikhewu.

1.4 Ukuhanjiswa kwamalungu esitena kugcwele, kuyalingana, kuyahambelana ngaphakathi nangaphandle, kunye nokwandiswa kwamalungu kufuneka kuhlangane neemfuno ze-2-3mm. Amalungu ezidumbu zezitena kuwo onke amalungu kufuneka atshixiwe. Umzimba wezitena ogqityiweyo awuyi kudlula kwisinye kwisithathu, kwaye umzimba wezitena ogqityiweyo awuyi kuba ngaphantsi kwesibini kwisithathu.

1.5 mg yokufaka kufuneka ihlikihlwe kwaye isasazwe ngesandla xa iwe ukusuka kubude bemitha enye. Ubungqingqwa kunye nokuqina kwento egcwaliswayo kufuneka ifane.

1.6 Sukusebenzisa izitena ezonakeleyo, ezimbombo nezimanzi ze-chrome-magnesium.

2. Izinto zokulawula izinto ezibandayo zokuthintela ukubola okuphezulu

Uvavanyo lubonisa ukuba xa isitena se-chrome-magnesia sinokumelana ne-thermal kwi-850 ℃, iya kwaphuka amaxesha ali-18, eya kuthi yenze umonakalo kumngxunya weziko. Ke ngoko, kubalulekile ukunqanda ukuguquguquka kobushushu besithando somlilo, ukunciphisa kunye nokuphelisa ukonakaliswa koxinzelelo lwethempe kwilitye lomlilo. Kwimveliso, ubushushu besithando somlilo sizinze ngokulawula ubungakanani bokutshaja kubanda.

3. Ukulawula ngokufanelekileyo umxholo we-silicon we-slag yokuguqula ukunciphisa ukubola kwemichiza

Ukungathathi cala okanye i-slag ebuthathaka engakhusela isithando somlilo. I-Olivine magnesia inefuthe elibi kakhulu. Ayinakunyibilika kuphela kumphezulu we-magnesia refractories, kodwa inokungena nakwizinto eziphakathi kwe-magnesia refractories.

Ukuphakama kobushushu, kokukhona ubukhulu be-MgO inyibilika kwisiguquli esiguquliweyo, kunye nokwenziwa kweforsterite enobushushu obuthambileyo obuphantsi komthwalo obushushu obuphezulu, okunciphisa ukusebenza kwezitena zemagnesia. I-iron oxide inokugcwalisa i-periclase kunye ne-chromite amasuntswana, ibangele ukonakala kwamasuntswana kunye nomonakalo okhawulezileyo kwizitena zemagnesia. Umxholo wesilicon we-slag yokuguqula ungaphantsi kwe-18%, eyi-alkaline, kwaye umxholo we-silicon we-slag yokuguqula ungaphezulu kwe-28%, ene-asidi. Umxholo we-silicon kwi-slag yokuguqula uphakathi kwe-19% kunye ne-24%, engathathi hlangothi okanye i-alkaline engenamandla, kwaye ayinakho ukubola kumgangatho wesitena se-magnesia. Ulawulo olungqongqo kumxholo wesilicon wesiguquli esiguquliweyo ngexesha lokuvelisa ukuzinzisa phakathi kwe-19% kunye ne-24%.

4. Ukuphucula umgangatho wabasebenzi

Ukuphucula umgangatho kunye nokukwazi ukwenza imveliso yeziko, ukusebenza kwesiguquli kunye nabasebenzi bolawulo lwemveliso ukuqinisekisa umgangatho wokuvelisa iziko.

Ukuphucula amandla okuphendula ngokungxamisekileyo, ulawulo lwenzululwazi nolungqongqo kunye nolawulo.

5. Ukukhetha ngokufanelekileyo ubungakanani bokunikezelwa komoya kunye noxinzelelo lweoksijini

Kwinkqubo yokuvelisa, ukungangqinelani phakathi komzimba womlilo kunye nefeni akunakuphepheka. Akuvunyelwe ngokungqongqo ukusebenzisa ifeni ukubonelela ngumoya kumzimba omncinci wesithando ukuthintela ukhukuliseko olukhulu kunye nokunyibilika okukhulu okuvuthelwe kwindawo ye-tuyere. Uxinzelelo lokunyusa ioksijini lwesiguquli akufuneki lube ngaphezulu kwe-27%, uxinzelelo lweoksijini kufuneka lube ngaphezulu kwe-27%, kwaye ulwelwesi lwezitena kufuneka luhlanjwe ngakumbi.
