Inkcazelo ye-Alumina Castable ephezulu
I-alumina castable ephezulu luhlobo lwe-refractory castable olusebenzisa izinto eziluhlaza ze-alumina eziphezulu njengee-aggregates kunye nomgubo uze wongezwe nge-arhente yokubopha. I-aluminium refractory castable ephezulu inamandla aphezulu oomatshini, ukumelana okuhle nokutsha kobushushu, ukumelana okuhle nokugqwala. I-alumina castable ephezulu ye-refractory yi-amorphous refractory enokushukuma okuphezulu, i-alumina castable ephezulu ye-refractory yenziwe nge-aggregate ye-refractory, umgubo, i-binder, izongezo, amanzi, okanye ezinye izinto ezingamanzi. I-alumina castable ephezulu ingasetyenziswa ngendlela yokubumba indawo, ukungcangcazela okanye ukuthambisa, kunye ne-preform inokwenziwa kwaye ingasetyenziswa ngendlela yokwakha i-casting kodwa iqiniswe ngaphandle kokufudumeza.
Iipropati ze-High Alumina Castable
- Ubunzima obuphezulu,
- Uzinzo lwevolumu,
- Ubushushu obuhle,
- Ukumelana ne-asidi,
- Ukunyamezelana nobushushu obuphezulu,
- Ukumelana kakuhle nobushushu,
- Ukumelana okuhle kwe-slag,
- Ukumelana nokuguguleka okuhle,
- Ukumelana nokugqwala okuhle,
- Ulwakhiwo lulula.
Inkqubo yokuvelisa i-High Alumina Castable enamanyathelo amahlanu
Khetha izinto ezikrwada ezenziwe ngezinto ezenziwe nge-aluminium ephezulu ngokwefomula.
Bala uhlengahlengiso kunye nomthamo we-aggregate, i-powder, i-binder kunye ne-additive ngokwefomula yezinto eziluhlaza, kwaye ulawule ngokungqongqo amasuntswana e-aggregate powder.
Faka i-aggregate enobunzima kunye nomgubo kwi-blender enye emva kwenye, uze uthele umgubo kwi-aggregate uze uxube imizuzu eyi-8-10.
Faka izinto ezixutyiweyo ze-aluminium ephezulu kwingxowa yetoni, zixhotyiswe ngezinto ezongeziweyo kunye ne-binder, uze uzipakishe.
Izinto ezipakishwe nge-aluminium eninzi mazigcinwe kwindawo yokugcina impahla, kwaye umhla kufuneka uphawulwe kwaye ungangenisi manzi kwaye ungangeni manzi.

Ukusetyenziswa kwe-High Alumina Castable
I-alumina castable ephezulu iveliswa emva kokuba yenziwe phantsi kobushushu obuphezulu kwi-rotary kwaye igrunjwe ibe ngumgubo. Le mveliso yenzelwe ukwenza ii-castables ezikumgangatho ophezulu ezinganyangekiyo, esisixhobo esisetyenziswa kwiindawo ezinobushushu obuphezulu kumashishini afana ne-metallurgy, izinto zokwakha, iikhemikhali, izityalo zombane. Kwakhona ii-castables ze-alumina eziphezulu zingasetyenziswa kwezi ndawo zilandelayo.
- I-rotary oven lining,
- I-lining ye-thermal converter,
- Ishishini lesinyithi,
- Ishishini leekhemikhali,
- Ishishini lokwakha.
