Yintoni intsimbi yekhabhoni ephezulu?

Intsimbi yeCarbon ePhezulu (iNtsimbi yeCarbon ePhezulu) eyaziwa njengesixhobo seNsimbi, umxholo weCarbon ukusuka kwi-0.60% ukuya kwi-1.70%, ukucima kunye nokuvutha.Izando kunye ne-crowbars zenziwe nge-0.75% ye-carbon steel;izixhobo zokusika ezifana ne-drills, iimpompo kunye ne-reamers zenziwe nge-0.90% ukuya kwi-1.00% ye-carbon steel.
Umphezulu wocingo lwentsimbi egudileyo, ugudile, akukho zintanda, amalungu, amanxeba, amanxeba kunye nomhlwa.Umaleko owenziwe ngegalvanized ufana, uncamathela owomeleleyo, ukuxhathisa umhlwa, ukuqina okugqwesileyo kunye nokunwebeka.

Ubunzima kunye namandla e-carbon steel high ikakhulu kuxhomekeke kwisixa sekhabhoni kwisisombululo, kunye nokwandisa kunye nomlinganiselo wekhabhoni kwisisombululo.Xa umxholo wekhabhoni udlula i-0.6%, ubunzima abunyuki, kodwa inani le-carbide elingaphezulu liyanda, ukuxhatshazwa kwentsimbi kuyanda, kwaye iplastiki, ukuqina kunye nokuqina kuyancipha.

Kule njongo, ngokuphindaphindiweyo ngokwemiqathango yokusetyenziswa kunye namandla ensimbi, ukuqina ukufanisa ukukhetha intsimbi eyahlukileyo.Umzekelo, ukwenza i-spring okanye i-spring-type part kunye namandla amancinci, khetha i-65 # intsimbi ephezulu yekhabhoni enomxholo ophantsi wekhabhoni.Intsimbi yekhabhoni ephezulu ngokubanzi ingasetyenziswa kwiziko lombane, iziko elivulekileyo, imveliso yokuguqula ioksijini.Umgangatho ophakamileyo okanye iimfuno zomgangatho okhethekileyo zingasetyenziswa ukunyibilikiswa kwesithando sombane kunye nokusetyenziswa kwevacuum okanye umbane, ukunyibilika kwe-slag.

Kwi-smelting, ukubunjwa kweekhemikhali, ngokukodwa umxholo wesulfure kunye ne-phosphorus, kulawulwa ngokungqongqo.Ukuze kuncitshiswe ulwahlulo kunye nokuphucula ipropathi ye-isotropic, i-ingot inokuthi ifakwe kwi-annealing yokushisa kwe-diffusion annealing (ibaluleke kakhulu kwisixhobo sensimbi) .Ngethuba lokusebenza okushushu, ukushisa kokumisa (i-rolling) yensimbi ye-hypereutectoid kufuneka ibe phantsi (malunga ne-800 ° C).Emva kokudibanisa kunye nokuqengqeleka, imvula ye-coarse network carbide kufuneka igwenywe.Ukuthintela i-surface decarburization ngexesha lokunyanga ukushisa okanye ukusebenza okushushu (ibaluleke ngakumbi kwintsimbi yasentwasahlobo) .Ngethuba lokusebenza okutshisayo, kufuneka kubekho umlinganiselo owaneleyo wokunyanzeliswa kokuqinisekisa umgangatho kunye nokusebenza kwenkonzo yentsimbi.
