Kodi high carbon steel ndi chiyani?

Chitsulo Chapamwamba cha Carbon (Chitsulo Chapamwamba cha Carbon) chomwe chimadziwika kuti Chitsulo cha Chitsulo, Zomwe zili ndi Mpweya kuchokera 0.60% mpaka 1.70%, kuzimitsa ndi kutentha.Nyundo ndi khwangwala zimapangidwa ndi 0,75% ya carbon steel;zida zodulira monga kubowola, matepi ndi ma reamers amapangidwa ndi 0.90% mpaka 1.00% carbon steel.
Pamwamba pa waya wazitsulo zachitsulo ndi wosalala, wosalala, wopanda ming'alu, mfundo, zokopa, zipsera ndi dzimbiri.Wosanjikiza malata ndi yunifolomu, adhesion wamphamvu, cholimba dzimbiri kukana, kulimba kwambiri ndi elasticity.

Kuuma ndi mphamvu ya carbon zitsulo makamaka zimadalira kuchuluka kwa mpweya mu njira, ndi kuwonjezeka ndi kuchuluka kwa mpweya mu njira.Pamene mpweya wa carbon uposa 0,6%, kuuma sikuwonjezeka, koma kuchuluka kwa carbide kumawonjezeka, kukana kwachitsulo kumawonjezeka pang'ono, ndipo pulasitiki, kulimba ndi kutsika kumachepa.

Kuti izi zitheke, nthawi zambiri malinga ndi momwe amagwiritsidwira ntchito komanso mphamvu yachitsulo, kulimba kuti agwirizane kusankha zitsulo zosiyanasiyana.Mwachitsanzo, kuti mupange kasupe kapena mtundu wa masika ndi mphamvu pang'ono, sankhani 65 # chitsulo cha carbon high chomwe chili ndi mpweya wochepa.General mkulu mpweya zitsulo angagwiritsidwe ntchito ng'anjo magetsi, lotseguka m'moto, mpweya Converter kupanga.Zofunikira zapamwamba kwambiri kapena zapadera zitha kugwiritsidwa ntchito kusungunula ng'anjo yamagetsi kuphatikiza kugwiritsa ntchito vacuum kapena magetsi, kusungunula kwa slag.

Mu smelting, mankhwala zikuchokera, makamaka zili sulfure ndi phosphorous, mosamalitsa ankalamulira.Pofuna kuchepetsa tsankho ndikuwongolera katundu wa isotropic, ingot imatha kulumikizidwa ndi kutentha kwapang'onopang'ono (makamaka pazitsulo zachitsulo).Pakugwira ntchito yotentha, kutentha koyimitsa (kugudubuza) kwachitsulo cha hypereutectoid kumafunika kukhala kochepa (pafupifupi 800 ° C).Pambuyo popanga ndikugudubuza, mvula ya coarse network carbide iyenera kupewedwa.Pewani kuwonongeka kwapamadzi panthawi yotentha kapena kugwira ntchito yotentha (makamaka zitsulo zamasika).Pakugwira ntchito yotentha, payenera kukhala chiŵerengero chokwanira cha kuponderezana kuti zitsimikizire ubwino ndi ntchito ya chitsulo.
