Isahani ya Alumina: Ibyingenzi byingenzi byo kurinda inganda no gukora neza

Mu musaruro w’inganda, abrasion, ubushyuhe bwinshi, hamwe na ruswa yangiza imiti akenshi bigabanya ibikoresho byubuzima kandi bikabangamira imikorere. Uwitekaisahani ya alumina—Byakozwe muri Al₂O₃ bifite isuku nyinshi kandi bigacumura hejuru ya 1700 ° C - bikemura izi ngingo zububabare. Hamwe na Rockwell ikomeye ya 80-90 HRA kandi ikambara kwihanganira inshuro 266 icyuma cya manganese, cyabaye ingenzi mubikorwa bikomeye. Hano haribikorwa byingenzi byibanze nimpamvu ari ishoramari ryubwenge kubucuruzi bugamije kugabanya ibiciro no kuzamura umutekano.

1. Ibyingenzi Byakoreshejwe Inganda

Isahani ya Alumina iruta iyindi ahantu habi, bigatuma iba ingenzi mumirenge aho ibikoresho bihanganira guterana amagambo, ingaruka, cyangwa ubushyuhe bukabije. Dore ibyo bakoresha hejuru:

Ingufu zamashanyarazi ninganda zamakara

Imiyoboro yamakara, pulverizeri, hamwe nu miyoboro ivu ivu mumashanyarazi nubucukuzi bwamabuye y'agaciro ahura nogusenyuka gukabije kwamakara. Imirongo gakondo yicyuma irashira mumezi, bigatera igihe gito. Imirongo ya Alumina yongerera igihe cyo kubaho inshuro zigera ku 10, igafasha imyaka yo gukomeza gukora. 1700 ° C irwanya ubushyuhe bwo hejuru nayo ikwiranye na sisitemu yo guteka hamwe numuyoboro usohora ivu.

Ibyuma, sima & ubucukuzi bw'amabuye y'agaciro

Mu gukora ibyuma, linine ya alumina irinda itanura riturika rya tapholes, urwego, hamwe niminwa ihindura icyuma gishongeshejwe n’isuri, byongera ubuzima bwa serivisi 50% +. Ku bimera bya sima na mine, batondekanya chute, urusyo, hamwe no gusya, bikingira amabuye y'agaciro na clinker. Imiyoboro yubucukuzi bwa Alumina igabanya imyambarire cyane, irinda kumeneka no kongera ibicuruzwa.

Inganda n’inganda

Ibimera bya shimi byishingikiriza kumurongo wa alumina kuri pompe, imiyoboro yububiko, hamwe nu miyoboro ikora acide yangirika, ibishingwe, hamwe na slurries. Barwanya aside irike ya sulfurike hamwe nibindi bitangazamakuru bikaze, birinda kumeneka no kwanduza ibicuruzwa. Mu gukora ibirahuri, ubushyuhe bwabo bwa 1600 ° C butuma biba byiza mu gutanura itanura, kubungabunga ibikoresho no kwemeza ubuziranenge bw’ibirahure.

Imikoreshereze yihariye

Kurenga inganda zingenzi, isahani yo hejuru (99% Al₂O₃) isahani ya alumina ikorera mu ikoti rya gisirikare ridafite amasasu (kurinda urwego 3-6) hamwe n’imodoka zitwaje ibirwanisho - igishushanyo cyoroheje cyongera ihumure nta guhungabanya umutekano. Mubishingwe, batondekanya utubuto n'utubuto, hamwe no gukuramo ibyuma bishongeshejwe no guhagarika ibikorwa.
