ʻO ka ʻokoʻa nui ma waena o ka annealing a me ka normalizing:

1. ʻOi aku ka wikiwiki o ka hoʻoluʻu ʻana o ka normalizing ma mua o ka annealing, a ʻoi aku ka nui o ka supercooling.
2. ʻO ka hoʻolālā i loaʻa ma hope o ka normalizing he mea maikaʻi ia, a ʻoi aku ka ikaika a me ka paʻakikī ma mua o ka annealing.

ʻO ke koho o ka annealing a me ka normalizing:

1. No ka haʻahaʻa carbon seamless kila paipu me ka kalapona maʻiʻo emi ma mua o 0.25%, normalizing maʻamau hoʻohana ma kahi o annealing. No ka mea hiki i ka wikiwiki hoʻoluʻu hiki ke pale i ka paipu kila liʻiliʻi kalapona mai ka ua o ka cementite tertiary manuahi ma ka palena o ka palaoa, a laila e hoʻomaikaʻi ai i ka hana deformation anu o nā ʻāpana stamping; hiki i ka normalizing ke hoʻomaikaʻi i ka paʻakikī o ke kila a me ka hana ʻoki ʻana o ka paipu kila seamless haʻahaʻa. ; Inā ʻaʻohe kaʻina hana wela ʻē aʻe, hiki i ka normalizing ke hoʻomaʻemaʻe i ka palaoa a hoʻomaikaʻi i ka ikaika o nā paipu kila liʻiliʻi kalapona.

2. Hiki ke hoʻohana maʻamau ʻia ka paipu kalapona i huki ʻia i ke anu anuanu me ke kalapona ma waena o 0.25% a me 0.5% ma kahi o ka annealing. ʻOiai ka waena-carbon kila anu-kauo seamless kila paipu me ka kalapona maʻiʻo kokoke i ka palena luna i kiʻekiʻe paakiki ma hope o normalizing, ka mea nō hiki ke oki, a me ka normalizing kumu kūʻai ua haʻahaʻa a me ka productivity kiʻekiʻe.

3. Cold-drawn seamless steel pipes with a carbon content between 0.5 and 0.75%, ma muli o ke kiʻekiʻe carbon content, ʻo ka paʻakikī ma hope o ka normalizing ʻoi aku ka kiʻekiʻe ma mua o ka annealing, a he mea paʻakikī ke hana i ka ʻoki ʻana, no laila ʻo ka annealing piha. hoʻohana maʻamau e hōʻemi i ka paʻakikī a hoʻomaikaʻi i ka machinability.

4. ʻO ke kalapona kiʻekiʻe a i ʻole ke kila kila me ke kalapona maʻiʻo > 0.75% o ka paipu kila liʻiliʻi i huki ʻia i ke anu e hoʻohana maʻamau i ka annealing spheroidizing ma ke ʻano he lapaʻau wela mua. Inā loaʻa kahi cementite lua, pono e hoʻomaʻamaʻa mua ʻia. ʻO ka Annealing kahi kaʻina hana wela kahi e hoʻomaʻamaʻa ʻia ai ka paipu kila liʻiliʻi i huki ʻia i kahi mahana kūpono, mālama ʻia no kekahi manawa, a laila hoʻomaha mālie. ʻO ka hoʻomaha mālie ka hiʻohiʻona nui o ka annealing. Hoʻomaʻalili ʻia nā paipu kila liʻiliʻi i hoʻohui ʻia ma lalo o 550 ℃ me ka umu a me ka ea. ʻO ka Annealing kahi hana wela i hoʻohana nui ʻia. I ke kaʻina hana o nā mea hana, nā ʻāpana a me nā ʻāpana mechanical, a me nā mea ʻē aʻe, ua hoʻonohonoho pinepine ʻia e like me ka hoʻomaʻamaʻa wela mua ma hope o ka hoʻolei ʻana, forging a me ka welding, a ma mua o ka ʻoki ʻana (kaʻiliʻili) e hoʻopau i kekahi o nā pilikia i hana ʻia e ka hana mua. nā hemahema, a hoʻomākaukau no nā hana ma hope.

Ke kumu hana hoʻohui:

①E hoʻomaikaʻi a hoʻopau paha i nā hemahema o ke kūkulu ʻana a me ke koena o ke koʻikoʻi i hoʻokumu ʻia e ke kila i ke kaʻina hana o ka hoʻolei ʻana, forging, rolling and welding, a pale i ka deformation a me ka haki ʻana o ka mea hana;
② hoʻopalupalu i ka mea hana no ka ʻoki ʻana;
③ Hoʻomaʻemaʻe i ka palaoa a hoʻomaikaʻi i ke ʻano e hoʻomaikaʻi ai i nā waiwai mechanical o ka mea hana;
④ E hoʻomākaukau i ka hui no ka hoʻomaʻamaʻa wela hope (quenching, tempering).
