Iindaba - IiParameters eziPhambili kunye neePropati ze-Hot-Rolled Steel Coil: Ukusuka kwiMveliso ukuya kwiSicelo

Kwishishini elikhulu lentsimbi,hot-rolled steel coilisebenza njengesiseko semathiriyeli, esetyenziswa ngokubanzi kumacandelo afana nokwakha, ukwenziwa koomatshini, kunye noshishino lweemoto. Ikhoyili yentsimbi yeCarbon, kunye nokusebenza kwayo konke okugqwesileyo kunye nokusebenza kakuhle kweendleko, iye yaba yinto eqhelekileyo kwimarike. Ukuqonda iiparameters zayo eziphambili kunye neepropathi akubalulekanga kuphela ekuthengeni izigqibo kodwa kukwabalulekile ekwandiseni ixabiso lemathiriyeli.

Kwimeko yomsebenzi wasefektri, umsebenzi onxibe isigcina-ntloko esiluhlaza kunye nevesti eluhlaza ubukele i-coil yentsimbi eshushu iphakanyiswa yi-crane. Ezijikelezileyo zipakishwe ngokucocekileyo iikhoyili zentsimbi eziqengqelekayo ezishushu. Iikhoyili zentsimbi ezinkulu kunye nokusingqongileyo okucwangcisiweyo kwefektri kubonisa ukuqina kunye nokumiselwa komgangatho wemveliso yentsimbi kunye nokulungiswa kwe-环节, kuqaqambisa indawo ebalulekileyo yeekhoyili zentsimbi eziqengqelekayo njengezinto ezisisiseko kwimveliso yemizi-mveliso, kwaye zikwahambisa umoya ongqongqo kunye nocwangco ngexesha lokusebenza kwefektri.

Ikhoyili yentsimbi ye-ASTM A36

Ukuveliswa kwekhoyili yentsimbi yeCarbon iqala kwicarbon steel coilumzi-mveliso, apho iibhilithi zicutshungulwa zibe ziikhoyili zenkcazo ethile ngenkqubo yokuqengqeleka kobushushu obuphezulu. Umzekelo,Ikhoyili yentsimbi ye-ASTM A36linqanaba lentsimbi elisetyenziswa ngokuqhelekileyo elichazwe yimigangatho ye-American Society for Testing and Materials (ASTM) kwaye ifunwa kakhulu kwiindawo zobunjineli bokwakha kunye nezakhiwo. Ikhoyili ye-ASTM A36 iqhayisa ngamandla esivuno se-≥250 MPa kunye namandla okuqina angama-400-550 MPa, kunye ne-ductility egqwesileyo kunye ne-weldability, ihlangabezana neemfuno zokuthwala kunye noqhagamshelo lwezakhiwo ezinkulu ezinjengeebhulorho kunye nezakhelo zefektri. Ukubunjwa kwayo kweekhemikhali ngokuqhelekileyo kugcina umxholo wekhabhoni ngaphantsi kwe-0.25%, ngokufanelekileyo ukulinganisa amandla kunye nokuqina ngelixa ugwema i-embrittlement ehambelana nomxholo wekhabhoni.

Ukususela kumbono weparameter, ubukhulu, ububanzi, kunye nobunzima bekhoyili zizibonakaliso ezibalulekileyo zokuvavanya ukusebenza kweentsimbi zetsimbi ezishushu. Ubunzima obuqhelekileyo buvela kwi-1.2 ukuya kwi-25.4 mm, ngelixa ububanzi bunokugqithisa i-2000 mm. Ubunzima bekhoyili bunokwenziwa ngokwezifiso, ngokuqhelekileyo buqala ukusuka kwi-10 ukuya kwiitoni ezingama-30. Ulawulo oluchanekileyo lwe-dimensional aluchaphazeli kuphela ukusebenza kakuhle kodwa lukwachaphazela ngokuthe ngqo ukuchaneka kwemveliso yokugqibela. Ngokomzekelo, ukunyamezela kobunzima beentsimbi zetsimbi ezishushu ezisetyenziselwa ukuveliswa kweemoto kufuneka zilawulwe ngokungqongqo ngaphakathi kwe-± 0.05 mm ukuqinisekisa imilinganiselo ehambelanayo yeengxenye ezigxininisiweyo.
