ASTM Standard Hot Rolled Steel Coils: Magiredhi Akakosha, Zvinhu Zvinokosha, uye Mashandisirwo Emaindasitiri

Makoiri esimbi anopisa akamonerwa(HRC)Zvigadzirwa zvinoenderana neASTM zviri pakati pezvigadzirwa zvesimbi zvinoshandiswa zvakanyanya mumusika wepasi rose, kunyanya kuNorth neSouth America yese. Nekuda kwehunhu hwazvo hwakagadzikana hwemakanika, kusarudzwa kwemhando yakakura, uye kushanda zvakanaka kwemari, maASTM hot rolled steel coils anoita basa rakakosha mukuvaka, kugadzira, mota, uye indasitiri hombe.

Zvichienderana nekushanda kwemuchina uye zvinodiwa pakushandisa, ASTM hot rolled steel coils dzinogona kuiswa muzvikamu zvitatu zvikuru: carbon structural steel, high-strength low-alloy steel (HSLA), uye commercial & drawing-quality steel.

1. Magiredhi eSimbi yeCarbon Structural

Magiredhi akajairika anosanganisira ASTM A36, ASTM A283 Giredhi C, uye ASTM A1011 SS36 / SS40. Magiredhi aya anoonekwa sema coil esimbi anopfurwa nekabhoni anonyanya kushandiswa uye anoshandiswa zvakasiyana-siyana mumusika weAmerica.

Makoiri esimbi esimbi ecarbon anozivikanwa nekusimba kwawo kwakaringana, kugona kusundira zvakanaka, uye nyore kugadzira. Anoita basa rakavimbika pasi pemamiriro ezvinhu akajairwa ekutakura uye akakodzera kushandiswa kwakasiyana-siyana kwemainjiniya.

Mukuita, zvinhu izvi zvinoshandiswa zvakanyanya muzvivakwa zvesimbi, mabhureki, maplate epasi, mafuremu, uye zvikamu zvekugadzira zvakajairika. Nekuda kwekugamuchirwa kwazvo pasi rose uye kuwanikwa kwakasimba, mamakisi eASTM carbon structural HRC anowanzo kuve sarudzo yekutanga kumapurojekiti anotarisana nekutengesa kunze kwenyika uye mabasa ekuvaka akajairwa.

2. High-Simba Low-Alloy (HSLA) Simbi Magiredhi

Kune mapurojekiti anoda simba rakawanda uye kushanda zvakanaka kwehuremu, ASTM A572 Giredhi 50, ASTM A992, uye ASTM A1011 HSLAS Giredhi 50 zvinowanzotsanangurwa.

Masimbi eHSLA anogadzirwa nesimbi inopisa anogadzirwa kuti ape goho rakakura uye simba rekusunga uku achichengetedza kuchinjika kwakanaka uye kusimba. Kana tichienzanisa nesimbi yenguva dzose yekabhoni, magiredhi aya anobvumira mainjiniya kuderedza kushandiswa kwesimbi pasina kukanganisa kuchengetedzeka kwechivako, zvichiita kuti zvive zvakanaka kune zvivakwa zvikuru uye zvinotakura mutoro.

Mashandisirwo akajairika anosanganisira mabhiriji, zvivakwa zvesimbi zvirefu, mafekitori emaindasitiri, matura, uye mafuremu emidziyo inorema. ASTM A992, kunyanya, ndiyo yave chinhu chakajairika chematanda ekuvaka nemakoramu mukuvaka simbi yemazuva ano yeAmerica.

3. Simbi Inopisa Yakamonerwa Yemhando Yepamusoro Yekutengeserana & Yekudhirowa

Magiredhi akadai seASTM A1011 CS Type B neASTM A1011 DS akagadzirwa nepfungwa yemhando yepamusoro uye kugona kugadzirwa zvakanaka.

Makoiri esimbi yekutengeserana (CS) anogadzirwa nesimbi inopisa anopa ukobvu hwakafanana uye nzvimbo dzakatsetseka, zvichiita kuti dzikwanise kugadzirwa zvakajairika uye kugadzirwa zviri nyore. Asi simbi inodhirowa (DS), kune rumwe rutivi, inoita kuti simbi ishande zvakanaka uye ishande zvakafanana, zvichiita kuti zvive zvakaoma kudhirowa nekukotama.

Magiredhi aya anoshandiswa zvakanyanya muzvikamu zvemotokari, midziyo yemumba, mavharo, mapaneru, uye zvigadzirwa zvakagadzirwa nechando, uko kugadzira mashandiro uye chitarisiko chepamusoro ndizvo zvinhu zvakakosha kufunga nezvazvo.

Simba reRoyal Group reKupa uye Mabhenefiti Ebasa

Royal Group inopa mhinduro imwe chete yeASTM hot rolled steel coils, kusanganisira:

Kufukidzwa kwemhando dzakasiyana-siyana: ASTM A36, A283 Gr.C, A572 Gr.50, A992, A1011 CS / DS / HSLAS

Saizi dzinochinjika uye masevhisi ekucheka akagadzirwa nemaoko

Kurongedza kwehunyanzvi hwekutengesa kunze kwenyika kwesimbi dzesimbi

Nguva yakagadzikana yekutungamira uye rutsigiro rwepasi rose rwezvinhu

Rutsigiro rwehunyanzvi uye mhinduro yekukurumidza yekotesheni

Nekubatanidza mhando yezvigadzirwa zvinovimbika nebasa rinoshanda, Royal Group inoramba ichibatsira vatengi vepasi rose kuderedza njodzi dzekutenga uye kuvandudza mashandiro ekutengesa.

Kutsigira Mapurojekiti Esimbi Epasi Rose Nechivimbo

Kubva pamakoiri esimbi ekabhoni akajairwa kusvika kumakoiri esimbi eHSLA ane simba guru uye makoiri esimbi esimbi anoputika ekutengeserana, Royal Group inoramba yakazvipira kupa mhinduro dzesimbi dzinoputika dzinoenderana neASTM dzekuvaka, kugadzira, uye kushandiswa kwemaindasitiri pasi rese.

Sezvo kuvandudzwa kwezvivakwa uye kugadzirwa kwemaindasitiri kuri kuramba kuchikura pasi rose, masimbi esimbi anoputika eRoyal Group eASTM acharamba ari sarudzo yakavimbika kune vanobatana vari kutsvaga mhando, kugara kwenguva refu, uye kushanda pamwe kwenguva refu.
