GB3087 Low matsakaicin matsin lamba boiler seamless bututu
Matsayi:
GB3087 -------- Tsarin kasar Sin
Bayani:Bayani na seamless karfe bututu aka nuna da waje diamita * bango kauri mm.
Low matsakaicin matsin lamba boiler bututun da ake amfani da su yi daban-daban low matsakaicin matsin lamba boiler, overheating tururi bututun, tukunyar ruwa bututun, ruwa sanyi bangon bututun da kuma motar boiler da overheating tururi bututun, manyan hayaki bututun, kananan hayaki bututun da kuma arch tubali bututun da sauransu. Seamless karfe bututu tare da high quality carbon tsarin karfe zafi madaidaiciya ko sanyi madaidaiciya (dial). Yawancin da aka yi da karfe na 10, 20, ban da tabbatar da sinadarai da kayan aiki na inji don yin gwajin matsin lamba na ruwa, madaidaiciyar gefe, fadada, flattening da sauran gwaje-gwaje. Hot madaidaiciya isarwa a cikin zafi madaidaiciya jihar, sanyi madaidaiciya (dial) isarwa a cikin zafi magani jihar.
Manufacturing Tsarin
Hot madaidaiciya (matsawa seamless karfe bututu): zagaye bututu blank → dumama → perforation → uku madaidaiciya sloping madaidaiciya, ci gaba madaidaiciya ko matsawa → stripping → daidaita diamita (ko rage diamita) → sanyaya → daidaitawa → ruwa matsin lamba gwaji (ko ganowa) → alama → ajiya
Cold jawo (madaidaiciya) seamless karfe bututu: zagaye bututu blank → dumama → perforation → kicking → annealing → acid wanke → rufe mai (jan ƙarfe) → Multiple sanyi jawo (sanyi madaidaiciya) → blank bututu → zafi magani → daidaitawa → hydraulic gwaji (gano rauni) → alama → ajiya.
Amfani:
Ana amfani da matsakaicin low matsin lamba boiler (aiki matsin lamba ba yawanci bushewa 5.88MPa, aiki zafin jiki a kasa da 450 ~ C) da zafi surface bututun, kwantena da tururi bututun.
