Anneal karfe bututu

Cold rolled black annealed karfe bututu, wani nau'i ne na bututun karfe wanda aka yi na'ura mai sanyi wanda ya biyo baya. Tsarin jujjuyawar sanyi ya haɗa da wucewar ƙarfe ta cikin jerin rollers a yanayin zafin ɗaki don rage kaurinsa da haɓaka ƙarshensa. Wannan na iya haifar da santsi, mafi daidaiton saman da kuma jure juzu'in girma idan aka kwatanta da zafi mai birgima.

Bayan yin juyi sanyi, sai bututun karfen za a yi shi da wani tsari na cirewa, wanda ya hada da dumama kayan zuwa wani yanayi na musamman sannan a bar shi ya yi sanyi a hankali. Wannan mataki na annealing yana taimakawa wajen sauƙaƙa damuwa na ciki, tsaftace microstructure, da inganta ductility da machinability na karfe.

Sakamakon sanyi mai birgima baƙar fata bututun ƙarfe ana amfani da shi sau da yawa a aikace-aikace inda ake buƙatar ƙarewar ƙasa mai santsi da madaidaicin girma, kamar a cikin kayan daki, kayan aikin mota, da wasu aikace-aikacen tsari. Tsarin annealing kuma zai iya taimakawa wajen cimma ƙayyadaddun kaddarorin inji da haɓaka ƙirar ƙarfe.
