Isithando somlilo sikugcina njani ukuzinza kweatmosfera eziko?

Ukuze ulawule umoya kwisithando somlilo kwaye ugcine uxinzelelo kwisithando somlilo, indawo yokusebenza kwisithando somlilo kufuneka ihlale isodwa ngaphandle emoyeni, kwaye ukuvuza komoya kunye nokungena komoya kufuneka kugwenywe kangangoko kunokwenzeka. Ke ngoko, zonke iinxalenye zoqhagamshelo zangaphandle ezifana negobolondo lesithando somlilo, isakhiwo semasonry, umnyango wesithando somlilo kunye nefeni, i-thermocouple, ityhubhu ekhanyayo, i-push-pull feeder, njl. ukuze kugcinwe amandla aphezulu ekhabhoni kwisithando somlilo, ngaphandle Ngaphandle kokulawula ukuzinza kokubunjwa kwe-atmosphere, umoya wesithando somlilo kufuneka ulawulwe ngokuzenzekelayo. Ngoko ke, kuyimfuneko ukubonelela ngezixhobo zokulawula ezahlukeneyo ngokuqhubekayo kunye namaxesha athile kunye nokulungelelanisa ukunikezelwa kwegesi kwisithando somlilo.

Ukuqinisekisa ukuzinza kweatmosfera yesithando somoya, i-atmospheric furnace inokwahlulwa ibe ziindidi ezimbini: i-muffle furnace kunye ne-muffle furnace. Idangatye lomlilo we-muffle lingaphandle kwesithando somlilo, kwaye i-workpiece ishushu ngokungathanga ngqo kwisithando somlilo. Ityhubhu ekhazimlayo yomlilo okanye ityhubhu yombane yombane yahlula idangatye okanye umzimba wokufudumeza umbane kwirhasi yesithando somlilo ukuphepha ukuzinza kwe-atmosfera kwisithando somlilo esaphukileyo.

Ukuxutywa kokunciphisa igesi kunye nomoya kufikelela kumlinganiselo ophezulu wokuxuba, kwaye kulula ukubangela ukuqhuma kwiqondo lokushisa eliphezulu. Ke ngoko, amagumbi angaphambili nangasemva, igumbi lokucima kunye negumbi lokupholisa elicothayo lesithando somlilo lixhotyiswe ngezixhobo ezinobungqina bokudubula. Ikwaxhotyiswe ngegesi yesithando somlilo kunye nenkqubo yokulawula ukukhupha, efuna amanyathelo obungqina bokuqhuma.

Isithando somlilo sisebenzisa igesi yokunciphisa. Ukuze ungachaphazeli ubomi benkonzo ye-masonry kwaye ungonakalisi umoya oqhelekileyo wesithando somlilo, umzimba wesithando somlilo kufuneka wenziwe ngezinto ezichasene ne-carbonization refractory.

Iziko ezahlukeneyo zomoya zineemfuno eziphezulu zokutywinwa, kwaye ukulayisha okuntsonkothileyo kunye nokukhuphela imisebenzi kufuna isithando somlilo ngeenjongo ezininzi. Kwimveliso yobuninzi, zidityanisiwe kunyango lobushushu oludibeneyo oluzinikeleyo okanye oluneenjongo ezimbini, ngoko ke kufuneka iqondo eliphezulu lomatshini. iqondo lokuzenzekela.
