Isahani yo gushyiramo alumina: Ikoreshwa ry'ingenzi mu kurinda no kunoza imikorere y'inganda

Mu nganda, kwangirika, ubushyuhe bwinshi, no kwangirika kw'ibinyabutabire akenshi bigabanya igihe cyo kubaho kw'ibikoresho kandi bikabangamira imikorere myiza.isahani yo gushyiramo alumina—yakozwe muri Al₂O₃ ifite isuku nyinshi kandi ikaranze ku bushyuhe burenze 1700°C—ikemura ibi bibazo by'ububabare. Kubera ko ifite ubukana bwa Rockwell bwa HRA 80-90 kandi idashobora kwangirika inshuro 266 z'icyuma cya manganese, yabaye ingenzi mu nganda zikomeye. Dore ikoreshwa ryayo ry'ingenzi n'impamvu ari ishoramari ryiza ku bigo bigamije kugabanya ikiguzi no kongera umutekano.

1. Porogaramu z'ingenzi mu nganda

Amasahani ya alumina ni meza cyane mu bidukikije bikomeye, bigatuma aba ingenzi cyane mu bice aho ibikoresho bihora bihura n'ibibazo, ingaruka cyangwa ubushyuhe bukabije. Dore uburyo bikoreshwa cyane:

Inganda zikora ingufu z'ubushyuhe n'amakara

Imashini zitwara amakara, imashini zitunganya amakara, n'imiyoboro y'ivu mu nganda zitanga ingufu zishyuha n'ibirombe bicukurwamo amabuye y'agaciro zihura n'uburibwe bukomeye buterwa n'uduce tw'amakara. Imashini zisanzwe zikoresha ibyuma zishaje mu mezi make, bigatuma zidakora neza. Imashini zikoresha alumina zongera igihe cyo kubaho kw'ibice kugeza ku nshuro 10, bigatuma zikora imyaka myinshi. Ubushyuhe bwazo bukabije bwo kurwanya ubushyuhe bwinshi bwa 1700°C bukwiranye na sisitemu z'ubushyuhe n'imiyoboro isohora ivu.

Urwego rw'ibyuma, sima n'ubucukuzi bw'amabuye y'agaciro

Mu gukora ibyuma, imiyoboro ya alumina irinda imiyoboro y'ifuru, imiyoboro y'amazi n'iminwa ihindura ikirere kugira ngo bitangizwa n'isuri y'icyuma gishongeshejwe n'isuka, bigatuma ubuzima bw'ibikoresho burushaho kuba bwiza ku kigero cya 50%. Ku nganda za sima n'ibirombe, bishyira imiyoboro y'amazi, imiyoboro y'amazi n'imashini zisya, bikingira amabuye y'agaciro n'ingufu za clinker. Imiyoboro y'amazi icukurwamo alumina igabanya kwangirika cyane, ikarinda amazi kuva kandi ikongera ubushobozi bw'amazi.

Inganda zikora imiti n'ibirahure

Inganda zikora imiti zikoresha alumina liners kugira ngo zikore pompe, imiyoboro y’ibinyabutabire, n’imiyoboro ikora aside yangiza, ibishingiriro, n’ibisigazwa by’amazi. Zirwanya aside sulfure nyinshi n’ibindi bintu bikomeye, birinda kuva amazi no kwanduza ibicuruzwa. Mu gukora ibirahure, ubushyuhe bwabyo bwa dogere selisiyusi 1600 butuma ziba nziza cyane ku bikoresho byo mu itanura, kubungabunga ibikoresho no kwemeza ko ikirahure gihoraho.

Imikoreshereze yihariye

Uretse inganda z’ingenzi, plaque za alumina zifite isuku nyinshi (99% Al₂O₃) zikoreshwa mu makoti ya gisirikare adapfa amasasu (uburinzi bwo ku rwego rwa 3-6) n’imodoka zifite intwaro—imiterere yazo yoroheje yongera ihumure idasize inyuma umutekano. Mu nganda zikora ibyuma, zishyira imiyoboro y’amazi n’ibikoresho byo mu mazi, zihanganira kwangirika kw’ibyuma bishongeshejwe no gutuza ibyuma.
