Kodi pali kusiyana kotani pakati pa Q195, Q215, Q235, Q255 ndi Q275 malinga ndi zinthu?
Carbon imakhala ndi chitsulo chogwiritsidwa ntchito kwambiri, chiwerengero chachikulu chambiri chomwe chimagudubuzika mwa chitsulo, mbiri ndi maluso, nthawi zambiri siziyenera kugwiritsidwa ntchito mwachindunji kutentha, makamaka kolojekiti.
Q195, Q215, Q235, Q255, Q255 ndi Q275, kuwonetsa gawo la zitsulo, mtengo wake, wabwino, mtundu wina (a , B, C, D) njira yopanda zizindikiro ndi zina zonse zomwe zimapangidwa. Kuchokera pazinthu zamankhwala, makalata ofatsa Q195, Q215, Q215, Q255, Q255, Q255, Q255, Q275, Q255, Q255, Q275, Q275, Q255, Q275, Q255, Q255 Makina katundu kuchokera pamagawo, makasu omwe ali pamwambawa akuwonetsa kuti makulidwe ≤ 16mm a zitsulo zokolola. Mphamvu yake ya kuoneka inali: 3155-430, 355-450, 375-500, 410-550, 490-630 (Obn / MM2); Kufuula kwake kunali: 63, 31, 26, 24, 20 (0,5%). Chifukwa chake, pobweretsa zitsulo kwa makasitomala, makasitomala ayenera kukumbutsidwa kuti agule zinthu zosiyanasiyana za chitsulo malinga ndi zomwe zimafunikira, kuti musakhudze mtundu wa mankhwala.
Kodi pali kusiyana kotani pakati pa Q235A ndi zida za Q235b?
Q235A ndi Q235B ndi zonse za kaboni. Mu National Standard GB700-88, Q235a ndi Q235B Chuma chakuti makamaka mu kaboni katekeser, zomwe zili pazambiri za kaboni kaboni mu 0.14-% pakati; Zambiri za q235b sizimachita mayeso okhudza matendawa, koma nthawi zambiri amachita kutentha, V-offtch. Zojambulajambula zofananira, makinawo amakina a zinthu zam'madzi za Q235B ndiyabwino kwambiri kuposa momwe zinthu zilili. Mwambiri, mphero yachitsulo m'mabuku omaliziratu musanachoke fakitale yalembedwa pambale. Ogwiritsa ntchito amatha kudziwa ngati zinthuzo ndi Q235A, Q235B, kapena zida zina pamtengo.
Makulidwe achitsulo aku Japan ndi sphy, spod, etc. amatanthauza chiyani?
Chitsulo cha Japan (mndandanda) wa Japan Gawo lachiwiri la mawonekedwe osiyanasiyana, mitundu, imagwiritsidwa ntchito, monga p (prote) mbale, t (chubu), k (koloko) chida chimenecho. Gawo lachitatu la zigawo za nambala, nthawi zambiri mphamvu yocheperako. Monga: SS400 - yoyamba ija zitsulo (Steeel), yachiwiri, yomwe "kapangidwe" (400) yamphamvu yazitsulo. Pakati pawo: Sphy ----
SPHD ----- limatanthawuza kuwotcha pepala la zitsulo zowombera ndikukhota.
Spa ------ amatanthauza kutentha mapepala ndi zingwe zojambulira zozama.
SPCC ----- imatanthawuza chofunda cholumikizidwa chokulungira kaboni pang'ono ndikugwiritsa ntchito quex General, ofanana ndi China Q195-215A grade. Kalata yachitatu C ndi chidule chozizira, chomwe chimafunikira kuonetsetsa kuyesa kwa Tansile kumapeto kwa kalasi kuphatikiza spcct.
SPCD -----
Syce ----- Kuonetsetsa kuti kusagwiritsa ntchito magwiridwe antchito, onjezerani n kupita kumapeto kwa kalasi.
Wozizira wowumbika masitepe a starbon steel ndi stription yolumikizira, yofinya wa a, yokhazikika kwa s, 1/8 hard kwa 8, 1/4 yovuta kwa 4, 1/2 hard kwa 2.
Padziko Lonse Lapansi: Palibe mawu omaliza a D, prosh kumaliza ntchito ya B. Monga SpCcti-SD ikuwonetsa mawonekedwe ozizira ogundana, palibe pepala lozizira la mpweya kuti mugwiritse ntchito. Kenako Spcct-SB imawonetsa kukwiya, kumaliza bwino, mapepala ozizira ozizira ndi makina otsimikizika.
