Chitoliro cha Carbon Steel ndi chitoliro chachitsulo cha aloyi
Kampani yathu imachita bizinesi yogulitsa kunja kwa chitsulo cha carbon ndi alloy steel.Aloyi Pipe, aloyi chitsulo chitoliro, Aloyi Zitsulo Pipe China, carbon pipe, Chitoliro cha Carbon Steel, Chitoliro cha Carbon Steel China.
Kodi mukudziwa kusiyana pakati pa carbon steel ndi alloy steel?
Chitsulo cha carbon:makamaka amatanthauza katundu mawotchi zimadalira mpweya zili zitsulo, ndipo zambiri sawonjezera zinthu zambiri alloying zitsulo, nthawi zina amatchedwa kumveka mpweya zitsulo kapena mpweya zitsulo. Mpweya zitsulo, amatchedwanso mpweya zitsulo, mpweya zili WC zosakwana 2% chitsulo mpweya aloyi.
Mpweya zitsulo kuwonjezera zambiri lili pang'ono pakachitsulo, manganese, sulfure, phosphorous akhoza kugawidwa malinga ndi ntchito mpweya zitsulo mpweya structural zitsulo, mpweya chida zitsulo ndi ufulu-kudula structural zitsulo atatu mpweya structural zitsulo lagawidwa mu structural zitsulo ndi makina structural zitsulo, amene akhoza kugawidwa mu otsika mpweya zitsulo (WC ≤ 0,25%), sing'anga mpweya zitsulo (WC 0.25% - 0.6%) ndi zitsulo mkulu mpweya (WC> 0,6%).
Malinga ndi phosphorous ndi sulfure okhutira, zitsulo mpweya akhoza kugawidwa mu zitsulo wamba mpweya (phosphorous ndi sulfure ndi apamwamba), apamwamba zitsulo mpweya (phosphorous ndi sulfure m'munsi) apamwamba zitsulo (phosphorous, sulfure m'munsi).
Chitsulo chachitsulo:zochokera ku carbon zitsulo, chimodzi kapena zingapo aloyi zinthu anawonjezera mwadala kusintha serviceability ndi ndondomeko ntchito aloyi ofotokoza chitsulo amatchedwa aloyi zitsulo. Aloyi zitsulo amatanthauza zitsulo munali pakachitsulo ndi manganese monga zinthu alloying kapena deoxidizing zinthu, zinthu zina alloying monga chromium, faifi tambala, molybdenum, vanadium, titaniyamu, mkuwa, tungsten, zotayidwa, cobalt, niobium, zirconium ndi zinthu zina, ndi zinanso. zili ndi zinthu zina zosakhala zitsulo (monga boron, nitrogen, etc.) zitsulo.
Malinga ndi kuchuluka kwa zinthu alloying mu zitsulo, komanso akhoza kugawidwa mu otsika aloyi zitsulo, sing'anga aloyi ndi mkulu aloyi zitsulo.
Kusiyana kwa Chemical:
(1) Chitsulo cha carbon: Chitsulo chochepa cha carbon (C≤0.25%); Sing'anga mpweya zitsulo (C≤0,25 ~ 0,60%); Zitsulo zapamwamba za carbon (C≤0.60%).
(2) Chitsulo chachitsulo: Chitsulo chochepa cha alloy (chiwerengero chonse cha zinthu zowonjezera ≤ 5%); Sing'anga aloyi chitsulo (chiwerengero zili aloyi zinthu> 5 ~ 10%); High aloyi zitsulo (chiwerengero cha zinthu alloying> 10%.
Ubwino wachitsulo cha carbon:
Chitsulo cha kaboni chili ndi mphamvu zambiri, ductility ndi kulimba, mtengo wotsika, womwe umagwiritsidwa ntchito pamakina olemetsa popanga zida zolemetsa. Angapezeke ndi kutentha mankhwala bwino makina katundu kuponyedwa.
Ubwino wa Alloy Steel:
Kuwonjezera chitsulo mu zinthu zitsulo munali yekha carbon zitsulo, mpweya zitsulo, pakachitsulo ena, sulfure, phosphorous ndi zosafunika zina. Kuwonjezera zinthu zina za chromium, manganese, molybdenum, titaniyamu, tungsten, vanadium, niobium, boron, pakachitsulo faifi tambala aloyi zitsulo kukwaniritsa ankafuna katundu monga kutentha, mkulu elasticity, abrasion kukana, mphamvu mkulu, mkulu toughness ndi zina zotero. pa. Aloyi kuuma zitsulo kuvala kukana, kuuma, kukana dzimbiri kuposa mpweya zitsulo zabwino.
Apa mutha kuwona zina zomwe zimagwiritsidwa ntchito kwambiriChitsulo cha carbonmagiredi akuthupi mu process piping.

Kugwiritsa ntchito
Imagwiritsidwa ntchito makamaka pamakina komanso kupanga ma cylinders a gasi, kuphatikiza machubu a kaboni ndi aloyi opanda makina osasunthika, ndipo amakwirira machubu amakina osasunthika komanso oziziritsa komanso osaziziritsa omwe amamaliza kuzizira mpaka kukula kwake ndi kuphatikiza 12 3⁄4 mu.
