1.Chii chinonzi Hot Rolled Steel Material Grades
Simbi isimbi yakasanganiswa ine kabhoni kadiki.Zvigadzirwa zvesimbi zvinouya mumagiredhi akasiyana zvichienderana nehuwandu hwekabhoni hwazviri.Iwo akasiyana makirasi esimbi akaiswa muzvikamu zvinoenderana neavo emukati kabhoni.Anopisa akakungurutswa simbi mamakisi akaiswa muanotevera kabhoni mapoka:
Kabhoni yakaderera kana simbi ine 0.3% kana shoma kabhoni nehuwandu.
Simbi yepakati-kabhoni ine 0.3% kusvika 0.6% kabhoni.
High-carbon steels ine zvinopfuura 0.6% kabhoni.
Zvishoma zvezvimwe zviwanikwa zvealloying zvakaita sechromium, manganese kana tungsten zvinowedzerwawo kugadzira mamwe mamakisi mazhinji esimbi.Akasiyana magiredhi esimbi anopa akati wandei akasiyana zvivakwa senge tensile simba, ductility, malleability, durability, uye thermal uye magetsi conductivity.
2.Kusiyana pakati peHot Rolled Steel uye Cold Rolled Steel
Zvizhinji zvezvigadzirwa zvesimbi zvinogadzirwa nenzira mbiri dzekutanga: kupisa kupisa kana kutonhora kukunguruka.Simbi inopisa yakakungurutswa inzira yeguyo iyo simbi inokungurutswa yakatsikirirwa patembiricha yakakwira.Kazhinji, tembiricha yesimbi inopisa yakakungurutswa inodarika 1700°F.Cold rolled steel inzira iyo simbi inotsikirirwa patembiricha yekamuri.
Zvakakosha kuziva kuti zvose zvinopisa zvakaputirwa simbi uye simbi inotonhora haisi magiredhi esimbi.Ndiwo maitiro e-pre-fabrication anoshandiswa kune zvakasiyana-siyana zvesimbi zvigadzirwa.
Hot Rolled Steel Process
Simbi inopisa yakakungurutswa inosanganisira kuumba nekukungurutsa masirabhu kuita mutsetse wakareba uchidziiswa pamusoro petembiricha yakanakisa.Iyo red-hot slab inodyiswa kuburikidza neyakatevedzana mamill mill kuti iumbe uye kutambanudza kuita chidimbu chitete.Mushure mekunge kuumba kwapera, simbi yesimbi inotonhodzwa nemvura uye yakakuvadzwa kuita coil.Mitemo yakasiyana-siyana yekutonhora kwemvura inovandudza mamwe metallurgical properties musimbi.
Normalizing inopisa yakakungurutswa simbi pakamuri tembiricha inobvumira kuwedzera simba uye ductility.
Simbi inopisa yakakungurutswa ndiyo inowanzo shandiswa pakuvaka, njanji, simbi, uye mamwe maapplication ayo asingade anoyevedza kupera kana maumbirwo chaiwo uye kushivirira.
Cold Rolled Steel Process
Simbi inotonhora inokungurutswa inodziiswa uye kutonhodzwa sesimbi inopisa inokungurutswa asi inozogadziridzwa zvakare uchishandisa annealing kana kuumburuka kwehasha kuti iwedzere kusimba uye kuburitsa simba.Iyo yekuwedzera basa uye nguva yekugadzirisa inowedzera kumutengo asi inobvumira padyo nedimensional kushivirira uye inopa huwandu hwakasiyana hwekupedzisa sarudzo.Iyi fomu yesimbi ine kupera kwakapfava uye inoshandiswa mumashandisirwo anoda chaiwo mamiriro epamusoro uye kushivirira kwedimensional.
Kushandiswa kwakajairika kwesimbi inotonhora inokungurutswa kunosanganisira zvimiro, fenicha yesimbi, midziyo yemumba, zvikamu zvemotokari uye hunyanzvi hwekushandisa panodiwa kunyatsojeka kana kunaka.
3.Hot Rolled Steel Grades
Simbi inopisa yakakungurutswa inowanikwa mumagiredhi akati wandei kuti isangane neprojekiti yako yakatarwa.IAmerican Society for Testing and Materials (ASTM) kana Sosaiti yeMotokari Engineers (SAE) inoisa zviyero uye mamakisi zvichienderana nesimbi yega yega chimiro uye kugona.
Magiredhi esimbi eASTM anotanga nebhii “A” rinomirira simbi dzine simbi.Iyo SAE grading system (inozivikanwawo seAmerican Iron and Steel Institute kana AISI system) inoshandisa nhamba ine manhamba ekuronga.Plain kabhoni simbi mamakisi mune ino system anotanga nedhijiti 10, ichiteverwa nenhamba mbiri dzinoratidza iyo carbon concentration.
Izvi zvinotevera magiredhi akajairika esimbi inopisa yakakungurutswa.Ndokumbira utarise kuti zvimwe zvigadzirwa zvinopihwa mune zvese zvinopisa uye zvinotonhora zvakatenderedzwa sarudzo.
