Ibyiza bya AR Steel?
Jindalai Steel itanga icyuma cya AR mu bwinshi bunini n'ubuto ku bashushanya n'abakora uruganda bashaka kongera igihe cyo gukora cy'ibice by'ingenzi no kugabanya uburemere bwa buri gikoresho gishyirwa mu bikorwa. Inyungu zo gukoresha icyuma kidashira mu bikorwa birimo kwangirika cyangwa guhindagurika kw'ibikoresho byo mu bwoko bwa abrasive ni nyinshi cyane.
Isahani y'icyuma idapfa kwangirika irakomeye cyane kandi ntipfa kwangirika, irinda neza gushwanyagurika no gucikagurika. Ubu bwoko bw'icyuma bukora neza mu bikorwa bikomeye, kandi bunatanga ubudahangarwa ku ngaruka. Isahani y'icyuma idapfa kwangirika izafasha kongera igihe cyo gukoresha kandi ikagabanya ikiguzi mu gihe kirekire.

Imiterere y'ibyuma bya AR400 na AR500
AR400 ni "iyakomeretse cyane", irwanya kwangirika, ikoreshwa mu byuma byambarwa. Ingano y'ubukomere ni 360/440 BHN ifite ubukomere busanzwe bwa 400 BHN. Ubushyuhe bwa serivisi ni 400°F. Iki gicuruzwa cya plate kigenewe gukoreshwa mu bikorwa aho hakenewe uburinganire bwiza mu miterere, gusudira, gukomera no kudashwanyagurika. Ibyuma birwanya kwangirika bikunze kugurishwa ku rwego rwo gukomera atari chemistry ihoraho. Hari itandukaniro rito mu bya chemistry bitewe n'urusyo rukora. Ibikoreshwa bishobora kuba birimo gukoreshwa mu bucukuzi bw'amabuye y'agaciro, mu mabuye y'agaciro, mu gutunganya ibikoresho byinshi, mu nganda z'ibyuma, no mu nganda zikora impumuro n'impapuro. Ibikoresho bya plate byambarwa byagenewe gukoreshwa mu gushyiramo liner; ntabwo bigenewe gukoreshwa nk'ibikoresho byigenga cyangwa ibikoresho byo guterura.
AR500 ni icyuma gifata imashini "gikomeye", kidakura cyane, kandi gikoresha alloy. Ingano y'ubukomere ni 470/540 BHN gifite ubukomere busanzwe bwa 500 BHN. Iki gicuruzwa cya plate kigenewe gukoreshwa mu bikorwa aho hakenewe uburinganire bwiza bw'ingaruka, ubukomere n'ubudakura. Ibyuma birwanya ubukomere bikunze kugurishwa ku rwego rwo gukomera ntabwo ari chemistry ihoraho. Hari itandukaniro rito mu buhanga bw'imiti bitewe n'urusyo rukora. Ibikoreshwa bishobora kuba birimo gukoreshwa mu bucukuzi bw'amabuye y'agaciro, mu mabuye y'agaciro, mu gutunganya ibikoresho byinshi, mu nganda z'ibyuma, no mu nganda zikora imashini n'impapuro. Ibikoresho bya plate bya plate byagenewe gukoreshwa mu gushyiramo liner; ntabwo bigenewe gukoreshwa nk'ibikoresho byigenga cyangwa ibikoresho byo guterura.
Amasahani y'icyuma ya AR400 VS AR450 VS AR500+
Inganda zitandukanye zishobora kugira "amaresipi" atandukanye y'icyuma cya AR, ariko ibikoresho bikorerwamo bihabwa ikizamini cy'ubukomere - kizwi nka Brinell Test - kugira ngo hamenyekane icyiciro biherereyemo. Ibizamini bya Brinell bikorerwa ku bikoresho by'icyuma bya AR akenshi byujuje ibisabwa na ASTM E10 byo gupima ubukomere bw'ibikoresho.
Itandukaniro rya tekiniki riri hagati ya AR400, AR450 na AR500 ni umubare w'ubukomere bwa Brinell (BHN), ugaragaza urwego rw'ubukomere bw'ibikoresho.
AR400: 360-440 BHN Ubusanzwe
AR450: 430-480 BHN Ubusanzwe
AR500: 460-544 BHN Ubusanzwe
AR600: 570-625 BHN Ubusanzwe (bidakunze kugaragara, ariko birahari)
