Faa'iidooyinka iyo Codsiyada
① Birta xagalka ah ee birta xagalka ahi waxay ku xasilan tahay agab ahaan, halabuurka aad ugu fiican, waxaana ku jira curiyaha dhifka ah ee Cr Mo, engegnaantiisa sare, gaar ahaan ku habboon dhisidda maraakiibta iyo dhuumaha iyo kuwa kale ee shaqada weyn.
② Qaadashada geeddi-socodka wax-soo-saarka birta xaglaha ah waa ka duwan yahay, habka wax-soo-saarka ma beddelo isku-dhafka alaabta ceeriin iyo sifooyinka.
③Waxaa si gaar ah loo isticmaalaa in lagu gooyo granite oo ka caawin kara macaamiisha si ay u gaaraan si degdeg ah-goynta hufnaan iyo siman goynta dusha loo aaneeyey in ay geesaha fiiqan, size lebbiska iyo caabbinta xirashada wanaagsan.
④ Qaadashada sharoobada birta xagal ma fududa in la jebiyo, boodh yar, si wax ku ool ah u wanaajin karto jawiga shaqada ee aqoon-is-weydaarsiga ciidda qarxinta, yaraynta culeyska boodhka ururiyaha ilaalinta deegaanka, iyo caafimaadka.
Birta cusub ee birta ah waxay ka samaysan tahay birta go'an taasoo ilaalisa FORGING STATE, laakiin aan ahayn CSTING STATE.Iyada oo habka xirfadeed ee deminta, burburinta, shaandheynta iyo daaweynta kulaylka gaarka ah, dhogorta noocan oo kale ah waxay muujinaysaa qaab xagal leh oo leh sifooyinka caabbinta abrasive iyo ductility saamaynta.Inta lagu jiro isticmaalka , waxaa la caddeeyey in qaabka xagal ee grit uu si tartiib tartiib ah u noqon doono arc, kaas oo ku habboon descaling dusha oksijiinta, nadiifinta dusha sare iyo fiiqan dusha sare, si ay si weyn u wanaajiso hufnaanta qarxinta iyo tayada daahan, iyo in la yareeyo tamarta kinetic. ee rinjiga, isticmaalka abrasive iyo wixii la mid ah, iyo sidoo kale in la kordhiyo nolosha qaybaha xidhashada.
