45#ukuqina kwensimbi emva kokucisha nokushisa

Ukuqina kwezingxenye ezingu-45# zensimbi ezicishiwe neziqinile ngemva kokucisha kufanele kufinyelele ku-HRC56~59, futhi amathuba okuba nesiphambano esikhulu aphansi, kodwa angeke abe ngaphansi kune-HRC48.

Icishiwe futhi ithukuthele 45 # insimbi I-45# insimbi iyinsimbi yesakhiwo ephakathi kwekhabhoni esebenza kahle ebandayo futhi eshisayo, izakhiwo ezinhle zemishini, amanani aphansi kanye nemithombo ebanzi, ngakho-ke isetshenziswa kabanzi. Ubuthakathaka bayo obukhulu ukuthi inokuqina okuphansi, izilinganiso ezinkulu ze-cross-sectional kanye nezidingo eziphezulu zezingcezu zokusebenza ezingafanelekile ukusetshenziswa.

Kuya

Izinga lokushisa lokucisha lensimbi elingu-45# lingu-A3+(30~50) ℃. Ekusebenzeni kwangempela, umkhawulo ophezulu uthathwa ngokujwayelekile. Izinga lokushisa eliphakeme lokucisha lingasheshisa ukushisisa kwendawo yokusebenza, kunciphise i-oxidation engaphezulu, futhi kuthuthukise ukusebenza kahle komsebenzi. Ukuze wenze i-homogenize ye-austenite ye-workpiece, isikhathi esanele sokubamba siyadingeka. Uma inani langempela lesithando somlilo elifakiwe likhulu, isikhathi sokubamba sidinga ukunwetshwa ngendlela efanele. Uma kungenjalo, kungase kube nobulukhuni obanele ngenxa yokushisa okungalingani. Kodwa-ke, uma isikhathi sokubamba siside kakhulu, okusanhlamvu okumahhadlahhadla kanye ne-oxidative decarburization ebucayi nakho kuzokwenzeka.

Kuya

Ukucisha kanye nokushisa: Ukucisha kanye nokuthulisa kuwukwelashwa kokushisa okuphindwe kabili kokucisha kanye nezinga lokushisa eliphezulu, futhi inhloso yako ukwenza ucezu lokusebenza lube nezakhiwo ezinhle ezihlanganisa konke. Insimbi ecishiwe nepholile inezigaba ezimbili: i-carbon quenched ne- tempered steel ne-alloy quenched kanye nensimbi epholile. Kungakhathaliseki ukuthi i-carbon steel noma i-alloy steel, okuqukethwe kwayo kwekhabhoni kulawulwa ngokuqinile. Uma okuqukethwe kwekhabhoni kuphezulu kakhulu, amandla ocezu lomsebenzi ngemuva kokucisha nokushisa aphezulu, kodwa ukuqina akwanele. Uma okuqukethwe kwekhabhoni kuphansi kakhulu, ukuqina kuzokwanda futhi amandla azobe enganele.
