4. Umboniso weMveliso:
5. Isicelo:
1) Umgangatho: EN10028 EN10222-2 2017 (umgangatho waseYurophu, umgangatho wangaphandle)
2) Ukuqamba: Ithiywe ngokomxholo we-C (carbon) kunye ne-Mo (molybdenum), okuthetha ukuba umxholo wekhabhoni
yale ntsimbi yentsimbi imalunga ne-160, ngelixa umxholo we-molybdenum umalunga nama-300.
3) Unyango lobushushu: ukunyanzeliswa okanye ukuqhelanisa + ukuvutha
4) I-16Mo3 ihluke kwezinye izinto xa i-welding. Kufuneka ifudunyezwe kuqala, kwaye i-weld kufuneka igcinwe ifudumele
malunga nemizuzu engama-30 emva kokuba ukuwelda kugqityiwe.
5)16mo3 intsimbi yemanganese ikwayinto ebalulekileyo yokuxutywa kwentsimbi kunye nento ebalulekileyo yokuqina, enento
impembelelo enkulu kukuqina kwentsimbi ye-weld.
6) Xa umxholo we-Mn we-16mo3 iplate yensimbi ingaphantsi kwe-0.05%, ukuqina kwentsimbi ye-weld kuphezulu kakhulu;
7) I-16mo3 ipleyiti yensimbi i-brittle kakhulu xa umxholo we-Mn ungaphezulu kwe-3%;
8) Xa umxholo we-Mn we-16mo3 iplate yensimbi yi-0.6-1.8%, i-TEL: i-180-377-99127% yentsimbi ye-weld inamandla aphezulu kunye nokuqina.
9) Yintoni umphumo wesulfure (S) ye-16mo3 yentsimbi yepleyiti ibe ne-weldability?
10) I-sulfure ihlala ikhona ngendlela ye-iron sulfide kwintsimbi, kwaye isasazwe kumda wengqolowa kwinethiwekhi, ngaloo ndlela ibaluleke kakhulu.
ukunciphisa ukuqina kwentsimbi. Ubushushu be-eutectic yentsimbi kunye ne-iron sulfide buphantsi (985°C). Ngoko ke, ngexesha lokucubungula okushushu,
iqondo lobushushu lokuqala lokucutshungulwa ngokuqhelekileyo yi-1150-1200 ° C, kwaye i-eutectic yentsimbi kunye ne-iron sulfide inyibilikile, okukhokelela ekubeni
ukuqhekeka ngexesha lokucubungula. Le nto ibizwa ngokuba "yi-hot brittleness yesulfure". Le propati yesulfure ibangela ukuba intsimbi
ukuphuhlisa iintanda ezishushu xa welding. Ngoko ke, umxholo wesulfure kwintsimbi ulawulwa ngokungqongqo. Umahluko ophambili phakathi
intsimbi eqhelekileyo yekhabhoni, intsimbi yekhabhoni ekumgangatho ophezulu kunye nentsimbi ekumgangatho ophezulu ngumxholo wesulfure kunye nephosphorus.
