Ludinga kangakanani udaka lokwakha ukwakha izitena ezikhanyelayo?

Izitena ezibonakalisayo zizinto eziyimfuneko ekwakheni iifanitshala zeshishini kunye neekiln. Phambi kokubeka izitena ezibonakalisayo, lungisa islurry esetyenzisiweyo. Ubungakanani obukhulu beengqungquthela ze-slurry akufanele kudlule i-20% yamalungu okudibanisa. Iimpawu zomzimba nezemichiza zodaka kufuneka zingqinelane nohlobo kunye nomgangatho wezitena ezitsalwayo. Xa kuthengwa izitena ezinokwakha, kungcono ukuba utyumbe umenzi ukuba alungiselele udaka oluhambelana nokuthintela ukuxubana.

Inkqubo yokulungisa udaka

Iimfuno ngokubanzi zokulungiselela udaka oluphikisayo kufuneka lusekwe kuhlobo lobugcisa, kwaye ukungaguquguquki kunye nomxholo wolwelo lwesilayidi kufuneka kugqitywe ngokusekwe kuvavanyo. Kwangelo xesha, jonga ukuba ngaba iipropathi zokwakha (ixesha lokubopha) legrout ziyahlangabezana neemfuno zolwakhiwo. Ixesha lokudibanisa le grout lixhomekeke kwinto kunye nobungakanani bemveliso enqabileyo, ngokubanzi akufuneki idlule kwimizuzu emi-2, kwaye inani kunye nokuhambelana kwamagrouts ahlukeneyo kukhethwe ngohlobo lobugcisa.

Ukumiselwa kokungaguquguquki kodaka kuya kwenziwa ngokweemfuno zomgangatho wangoku weshishini lukazwelonke “Indlela yoVavanyo yokuQiniseka kodaka oluPhambeneyo”. Ixesha le-slurry bonding limiselwa ngokungqinelana neemfuno zomgangatho wangoku wecandelo lesizwe “Indlela yoVavanyo yeXesha lokuDibanisa ixesha lokuDaka”.

Zimbini iindlela zokulungiselela udaka: indibaniselwano yendalo yamanzi kunye nokudityaniswa kwamachiza. Kwiitoni zokwakha iifanitshala kunye neekilnikhi, uninzi lwazo ludityaniswa ngokudityaniswa kwemichiza, kunye necoagulant ehambelana nayo iyongezwa. Lubonakala ngesantya sokuqinisa okukhawulezayo, amandla aphezulu okudibanisa, kwaye akukho brittleness emva kokuntywila kubushushu obuphezulu. Nangona kunjalo, emva kokufakwa kolwakhiwo lodaka olwenziwe ngamanzi, amanzi anobushushu obuphezulu kwiziko lokucoca umlilo, kulula ukwenziwa kodaka, kwaye ulwakhiwo alomelelanga. Ukongeza, i-slurry ekhanyisayo elungiselelwe kwangolo suku kufuneka isetyenziswe kwangolo suku lunye.

2: Ukubala indlela yokusetyenziswa kodaka

Okwangoku, akukho ndlela ilungileyo yokulinganisa imfuno yodaka lokuphika kwiziko lonke leziko. Ngenxa yeendidi ezahlukeneyo zomlilo kunye nezitena zeshishini, kunokwenzeka ukuba wakhe izitena ezinqabileyo ezinemilo ekhethekileyo. Izitena ezingekho mgangathweni okanye izikhundla zokwakha zahlukile, kwaye isixa sodaka olushenxisayo olusetyenziselwa ukwakha izitena olunye kudonga lomlilo nalo lwahlukile. Amazantsi eziko ahlukile. Okwangoku, isiseko sokusetyenziswa kwodongwe olubonakalisayo kuhlahlo-lwabiwo mali okanye uqikelelo lobunjineli beziko lobunjineli sisitena esichanekileyo esisetyenziselwa ukwakhiwa kweendonga zesithando somlilo. Ukongeza, ireferensi kufuneka yenziwe kumalungu odaka lokwakha, eliyiparameter esisiseko yokulinganisa udaka olushenxisayo olusetyenziswe kwizitena ezisemgangathweni ezichazayo. Amalungu omdaka wamatye kufuneka abekwe kuqala. Inqanaba lokuqala uthuthu komphunga ungaphantsi kwe 1mm, inqanaba lesibini lomthungo lincinci ngaphantsi kwe 2mm, kwaye inqanaba lesithathu lomthungo lingaphantsi kwe 3mm. Kwiintlobo ezintathu zamalungu odaka, amalunga odaka lwesibini aqhele ukusetyenziselwa izitena ezakhiwe ngodongwe okanye izitena eziphezulu zealumni.

Umzekelo, ukubala inani elipheleleyo lodaka lokuphika olufunekayo kwiziqwenga ezili-1000 zezitena eziphakamileyo zealuminium, indlela yokubala kufuneka yaziwe kuqala: a = udaka lwamatye oludibeneyo (2mm) B = ubukhulu bezitena kwindawo enye (T-3 ubukhulu I-230 * 114 * 65)

C = umgangatho wodaka olusetyenzisiweyo (ubunzima bodaka oluphezulu lwe-alumina ngama-2300kg / m3) d = ubungakanani bodaka olufunekayo kwisitena ngasinye. Okokugqibela, ukusetyenziswa kodaka d = 230 * 114 * 2 * 2500 = 0.13kg (ukusetyenziswa kwebhloko nganye). Ukusetyenziswa ngokupheleleyo kwe-1000 ye-alumina yezitena eziphikisayo malunga ne-130kg ye-slurry ye-refractory. Le ndlela yokubala sisiseko sokubala, kwaye ukusetyenziswa kwayo kufanele ukuba kube ngaphezulu kwe-10% yedatha yethiyori.
