Kugenzura ibyuma bitagira umwanda

Kugenzura ibyuma bidafite ingese hagati ya ruswa, 304 ibyuma bitagira umwanda, 304 ibyuma bitagira umuyonga hamwe na ruswa mu cyuma cyangirika hagati ya 10%, bizatuma guhuza ibinyampeke byagabanutse, imbere yibibazo, byoroshye kumeneka, ndetse no gusenyuka. , kandi byihishe, bitagaragara kuva imiterere yabyo.Iterwa kandi nizindi mpamvu nyamukuru zitera ruswa.Kwangirika kwingirangingo ya austenitis ibyuma bitagira umwanda biterwa nubukene ahanini biterwa nimbibi zimbuto Cr, Cr na c byoroshye imiti ivanze, ibirimo Cr.

1, imiterere yimiti nimiterere

(1) C ibirimo

C ibikubiye mubyuma byingaruka zo kwangirika kwicyuma cya austenitis ibyuma bidafite ingese nikintu gikomeye.Ku ruhande rumwe, igenzure neza c kandi ugumane ibintu bya karubone mubyuma fatizo no gusudira kuri 0.08%, ku cyuma fatizo hamwe n’ibikoresho byo gusudira byongeramo ibintu bya stabilisateur ya Ti, Nb, isano ikomeye na c, karubone mbere ya Cr bind, bitanga umusaruro uhamye ibice.

(2) ibyiciro bibiri

Ibyiciro bibiri byubaka bizongera cyane ubushobozi bwo kurwanya ruswa.Ku ruhande rumwe, wifatanije na ferrite ikora ibintu, nka chromium, Silicon, aluminium, molybdenum, gusudira gushinga ibyiciro bibiri, kumurongo watoranijwe wubaka urimo ferrite ibikoresho byinshi byo gusudira.

2, tekinoroji yo gusudira

.Gusudira ibyuma bitagira umwanda, gusudira birashobora gufatwa munsi ya laminate, cyangwa mu buryo butaziguye mu gukonjesha amazi yinyuma ya weld, kugirango bikonje vuba, bigabanye umwanya mubipimo byubushyuhe, ni ingamba zifatika zo kunoza kwangirika kwingingo.

(2) kongera ingufu zumurongo wo gusudira, bizihutisha kwangirika kwicyuma cya austenitis.Mugihe cyo gusudira, hamwe numuyoboro muke, umuvuduko mwinshi wo gusudira, mugufi-arc, uburyo bwinshi bwo gusudira, no kugabanya ubushyuhe.Ubushyuhe buke, muburyo bwo gukangurira ubushyuhe vuba bihagije kugirango wirinde kwangirika kwimiterere ya zone yibasiwe nubushyuhe.
