Indandatho Yokugaya yeMill

Ukumelana nokuguguleka kwezixhobo zomatshini wokugaya kubaluleke kakhulu. Ngokubanzi, abantu abaninzi bacinga ukuba okukhona imveliso inzima, kokukhona inokunxitywa ngakumbi, ngoko ke, uninzi lweenkampani ezisungula izinto zibhengeza ukuba izinto ezithungwayo zazo ziqulethe i-chromium, ubungakanani bufikelela kwi-30%, kwaye ubunzima be-HRC bufikelela kwi-63-65. Nangona kunjalo, okukhona usasazeko lusasazeka, kokukhona amathuba okwenza imingxunya emincinci kunye nemingxunya emincinci kwindawo ephakathi kwe-matrix kunye ne-carbides, kwaye amathuba okuqhekeka nawo aya kuba makhulu. Kwaye okukhona into inzima, kokukhona kunzima ukuyisika. Ke ngoko, ukwenza indandatho yokugaya engagugiyo nehlala ixesha elide akulula. Indandatho yokugaya ikakhulu isebenzisa ezi ntlobo zimbini zezixhobo zilandelayo.

I-65Mn (65 manganese): le nto inokuphucula kakhulu ukuqina kweringi yokusila. Ineempawu zobulukhuni obuphezulu, ukumelana nokuguguleka okugqwesileyo kunye nokumelana okuhle kwemagnethi, isetyenziswa kakhulu kwicandelo lokucubungula umgubo apho imveliso kufuneka isuse isinyithi. Ukumelana nokuguguleka kunye nokuqina kunokuphuculwa kakhulu ngokulungelelanisa nokulungisa unyango lobushushu.

I-Mn13 (13 manganese): ukuqina kwe-grinding ring casting nge-Mn13 kuphuculwe xa kuthelekiswa ne-65Mn. Ii-castings zale mveliso ziphathwa ngokuqina kwamanzi emva kokugalelwa, ii-castings zinamandla aphezulu okutyhafa, ubulukhuni, i-plasticity kunye neempawu ezingezizo zemagnethi emva kokuqina kwamanzi, okwenza i-grinding ring ihlale ixesha elide. Xa ichaphazeleka kakhulu kwaye itshintsha uxinzelelo olunamandla ngexesha lokusebenza, umphezulu uya kuqina kwaye wenze i-martensite, ngaloo ndlela yenza umaleko womphezulu onganyangekiyo kakhulu, umaleko wangaphakathi ugcina ubulukhuni obuhle, nokuba unxitywe kumphezulu omncinci kakhulu, i-grinding roller isenokumelana nemithwalo emikhulu yokukhwaza.
