Q235A mbale yachitsulo

Boiler zitsulo mbale zimagwiritsa ntchito popanga boilers zosiyanasiyana ndi zipangizo zofunika. Popeza mbale yachitsulo chowotchera imagwira ntchito pa kutentha kwapakati (pansi pa 350 ° C) ndi kupanikizika kwakukulu, kuwonjezera pa kupanikizika kwakukulu, imakhalanso ndi mphamvu, kutopa komanso kutentha kwa nthunzi yamadzi. Zimafunika kuti zitsimikizire mphamvu zina, ndipo zimakhala ndi kuwotcherera kwabwino komanso kuzizira. Maphunziro wamba: Q245R, A5155 kalasi 55, A5156 kalasi 60, Q235A carbon steel mbale, A5166 kalasi 65, A51670 kalasi.

Kutalikirana kwachitsulo chochepa cha alloy ndi 15% -23%, ndipo mphamvu yoyamwa mphamvu pa kutentha kwapakati ndi yayikulu kuposa 34J. Q235A mpweya zitsulo mbale, otsika aloyi mkulu mphamvu chitsulo ali ndi pulasitiki wabwino ndi kukana mphamvu, amene angapewe kusweka Chimaona ngati kugunda ndi kupanga kuzizira kupinda ndi kuwotcherera mosavuta. Kuonjezera apo, kutentha kwachitsulo kwachitsulo chochepa cha alloy ndi chochepa, ndipo kuyamwa kwazitsulo za E-grade zitsulo pa -40 ° C sikuchepera 27J. Izi ndizofunikira kwambiri pazainjiniya ndi njira zoyendera monga magalimoto, zombo, nsanja zamafuta akunyanja, zotengera, milatho, ndi zina zambiri.
