Liyini izinga lokushisa lokucisha le isithando somlilo

Iyini i-temperature yokucisha yesithando somlilo se-bogie? Ngokuvamile, izinga lokushisa lokucima liyancipha ukusuka ku-20 kuya ku-35 ° C.

1. Insimbi ene-rolling bear ngemuva kwe-spheroidization kanye ne-annealing inokusebenza okuhle kokusika, okubaluleke kakhulu ekukhiqizeni okuningi kwama-rolling bears kulayini wokuhlanganisa othomathikhi;

2. Ngemuva kwe-spheroidizing rolling bearing steel, isithando somlilo se-trolley sinamandla okukhathala okukhulu, ukumelana nokugqoka kanye nokuqina ngemva kokucisha kanye nokushisa okuphansi;

3. Okwensimbi egoqayo ngaphandle kwe-spheroidization, izinga lokushisa elicishayo lincane (20~35℃), kodwa ngemva kwe-spheroidization, izinga lokushisa lokucisha liyanwetshwa libe ngu-40 ~ 45℃, futhi ukuthambekela kokushisa ngokweqile nokuguqulwa nokuqhekeka ngesikhathi sokucisha kuyanwetshwa. kuncishisiwe. . Insimbi egingqayo ene-spheroidizing annealing process amaphuzu Insimbi ene-rolling ingasebenzisa ukupholisa okunensayo kwe-spheroidizing noma indlela efudumele ye-spheroidizing.

Ngokuvamile kukholakala ukuthi ububanzi obujwayelekile be-carbides eyindilinga ngemva kokufakwa kwe-anneal ngu-0.4 kuya ku-0.5 μm. Lapho isilinganiso sendawo yama-carbides ayindilinga esakhiweni esicishiwe sesithando somlilo se-trolley singama-7 kuya ku-8%, impilo ye-rolling bear.

Ngemuva kwe-spheroidizing annealing, lapho isilinganiso sendawo yama-carbides ayindilinga sicishe sibe ngu-15%, ukuze kusale u-7-8% wama-carbides ayindilinga ngemuva kokucisha esithandweni somlilo, usayizi wama-carbides ayindilinga ngemuva kokuhushulwa kufanele ulawulwe ngokuqinile ukuze uwenze. ebangeni lika-0.4 ~ 0.5μm. Ngalesi sizathu, isithando somlilo esizinzile nesinokwethenjelwa kufanele sisetshenziselwe ukwenza i-spheroidizing annealing.
