Izixhobo ze-Hardware zihlala zenziwe ngentsimbi, ubhedu kunye nerabha
Intsimbi: uninzi lwezixhobo zentsimbi zenziwe ngentsimbi
Ubhedu: Ezinye izixhobo zodushe zisebenzisa ubhedu njengesixhobo
Irabha: Ezinye izixhobo zodushe zisebenzisa irabha njengesixhobo
Ukuba ukwakheka kweekhemikhali kwahlulwe, kunokushwankathelwa njengeendidi ezimbini ezinkulu zentsimbi ye-carbon kunye ne-alloy steel.
Ikwahlulahlulwe ngamacandelo amathathu: insimbi yesakhiwo, insimbi yesixhobo kunye nentsimbi yokusebenza ekhethekileyo.
Ngokomgangatho, iintlobo ezintathu zetsimbi eziqhelekileyo, umgangatho ophezulu wensimbi uhlelwa.
carbon steel
Umxholo wekhabhoni wekhabhoni phantsi kwe-1.5%, umxholo wekhabhoni wensimbi ubizwa ngokuba yi-0.25% ye-carbon steel, i-0.25% ye-carbon steel ingaphantsi okanye ilingana ne-0.6% phakathi kwe-carbon steel, i-carbon steel kunye ne-carbon steel ephezulu. 0.6%.
Ngenxa yokuba i-phosphorus kunye ne-sulfure inokunyusa i-brittleness yensimbi kwiqondo lokushisa eliphantsi okanye ukushisa okuphezulu, umxholo we-phosphorus kunye nesulfure kwintsimbi kufuneka uchazwe xa umgangatho uhlelwa.Intsimbi eqhelekileyo, equlethe ngaphantsi kwe-0.045% umxholo wesulfure ngaphantsi kwe-0.055%.Umgangatho ophezulu wensimbi, umxholo we-phosphorus ungaphantsi kwe-0.04%, umxholo wesulfure ungaphantsi kwe-0.045%.Umxholo wesulfure wesixhobo sensimbi, P = 0.04% ngokulandelanayo.Kwinqanaba eliphezulu lensimbi, i-phosphorus kunye neemfuno zomxholo wesulfure zazingaphantsi kwe-0.03%.
Intsimbi yolwakhiwo lwekhabhoni isetyenziselwa ukwenza izinto ezahlukeneyo zobunjineli (ezifana nebhulorho, iinqanawa kunye nezixhobo zokwakha) kunye namalungu omatshini, anje ngegiya, iishafti kunye neentonga zokudibanisa, njl.
Insimbi yesixhobo seCarbon lolona lwimi luphambili lokwenza izixhobo ezahlukeneyo, izixhobo zokulinganisa, izixhobo ezichukumisayo kunye nezixhobo zehardware, ngokubanzi ezizezentsimbi yekhabhoni ephezulu.Carbon isixhobo steel steel nge "T", njengoko T7 wathi carbon carbon ingxubevange isixhobo steel 0.7%.Umgangatho ophezulu we-carbon tool steel umelwe ngu "A" emva kwenombolo, njenge "T7 A".
Iklasi yentsimbi.Olu hlobo lwetsimbi lunikezelwa njengesiqinisekiso sempahla yomatshini.Ngamabakala angama-1-7 ewonke, inani elikhulu lentsimbi, amandla amakhulu esivuno kunye namandla okuqina, kodwa i-elongation encinci.
Intsimbi yeKlasi B, olu hlobo lwensimbi lunikezelwa ngokubunjwa kweekhemikhali.Ngenani elipheleleyo lama-1-7 amabakala, inani elikhulu lentsimbi ye-B, i-carbon content content.
Intsimbi ye-alloy
Ukuze kuphuculwe iipropathi zomatshini, iipropathi zenkqubo, izinto ezibonakalayo kunye neekhemikhali zetsimbi, ezinye izinto ezixutywayo zongezwa kwintsimbi ngexesha le-smelting, ebizwa ngokuba yintsimbi ye-alloy.Umyinge wekhabhoni umxholo ongaphezulu kwe-1% yensimbi yensimbi ye-alloy xa umxholo wekhabhoni ungaphawulwanga, umxholo wekhabhoni ophakathi ungaphantsi kwe-1%, kunye nabambalwa kakhulu bathi.
Isixa esipheleleyo sezinto ezixutywayo kwintsimbi ebizwa ngokuba yi-5% yensimbi ephantsi, i-5% ngaphantsi kwento engaphantsi kwe-10% ye-alloy element eyaziwa ngokuba yintsimbi ye-alloy, i-alloy elements ebizwa ngokuba yi-10%, inani elipheleleyo lensimbi ephezulu ye-alloy.
Insimbi ye-alloy inokufumana iipropati zemishini ekunzima ukuyifumana kwi-carbon steel.
I-Chromium: ukwandisa ukuqina kwentsimbi kunye nokuphucula ukuxhathisa ukunxiba kunye nokunyusa ukuqina.
I-Vanadium: inegalelo elikhulu ekuphuculeni ubunzima, ukumelana nokunxiba kunye nokuqina kwentsimbi, ngakumbi ekuphuculeni ukuxhathisa ukunxiba kwentsimbi.
Mo: inokuphucula ukuqina kunye nokuzinza kwentsimbi, ukucoca ingqolowa kunye nokuphucula i-nonuniformity ye-carbides, ngaloo ndlela iphucula amandla kunye nokuqina kwentsimbi.
Iintsimbi ezisetyenziswa kwizixhobo zehardware
Ngenxa yeempawu ezikhethekileyo zomatshini wensimbi yensimbi ye-alloy, i-alloy tool steel idla ngokusetyenziswa kwi-hardware ye-hardware ephakathi kunye ne-high-grade.Isebenza ikakhulu kwiziko lokulungisa umphunga, umzi-mveliso weemoto, umzi-mveliso wamandla kunye namashishini emizi-mveliso kunye nemigodi anezinga eliphezulu lokusetyenziswa kwezixhobo kunye neemfuno eziphezulu zezixhobo.
Insimbi yensimbi yeCarbon idla ngokusetyenziswa kwizixhobo ze-hardware eziphantsi, ezinenzuzo yexabiso eliphantsi.Ifaneleka ikakhulu kubasebenzisi bamakhaya abanezinga eliphantsi lokusetyenziswa kwaye hayi imfuno ephezulu yezixhobo.
S2 intsimbi yentsimbi (edla ngokusetyenziselwa ukwenza iscrewdriver, screwdriver)
