I mea e hoʻomaikaʻi ai i ka paʻakikī o ka ʻili a me ke kūʻē ʻana opaipu huinahalike, hiki ke hana ia i kekahi o ka ili, oia hoi ka ili o ka lapalapa o ke ahi, kiʻekiʻe, ke alapinepine waena hardening ili a me kekahi lāʻau kemika a me nā mea like.ʻO ka maʻamau kiʻekiʻe, ka paʻakikī waena waena o ka hapa nui, ua wela ia ma kahi mahana o 850-950℃.Hāʻawi ʻia i kāna conductivity thermal maikaʻi ʻole, no laila ʻaʻole wikiwiki ka wikiwiki o ka hoʻomehana, i ʻole e hoʻoheheʻe ʻia me kekahi mau hemahema e kinai ana i nā māwae.ʻO nā koi paʻakikī induction Rectangular Pipe normalizing matrix hui ʻo ia ka pearlite.ʻO ka wai hoʻoheheʻe ʻana a i ʻole kahi hopena wai o ka waiʻona polyvinyl, ka mahana wela ma ka laulā o 200-400℃, paʻakikī 40-50HRC, paʻakikī a paʻa i ke kūpaʻa e hōʻoia i ka ʻili o ka Rectangular Pipe.

Loaʻa iā Rectangular pipe heat treatment nā pono ʻekolu:

(A) Kiʻekiʻe dimensional paʻa no ka pololei rectangular paipu, e pono kiʻekiʻe precision, pono e malama i dimensional paʻa, e like me ka hopena kula pololei i ka lewa, ua lohi ka hooluolu ana, no laila, i ka hana o austenite ua stabilized e hoonui i ka nui o ka paa. austenite ʻiʻo rectangular paipu, pono e mālama anu;

(B) E ho'ēmi i ka quenching distortion ma muli o ka elongated square a me ka rectangular tube, no laila paʻakikī kaʻina hana maʻalahi deformed, pono e hoʻomalu pono deformation, ka wela wela mea koʻikoʻi kaʻina i ka quenching kaʻina hana, ka hoʻohana 'ana i ka plastic e supercooled austenite alignment manawa. kahi kī e hōʻoia i kā lākou conformity rate, no ka mea, e hoʻopau ana i ka ʻauʻau wela a i ʻole ka hoʻomaʻamaʻa wela hoʻopololei i manaʻo ʻia i kekahi manawa ʻoiai e kau ʻia ka wela ma luna o ka hoʻomehana ʻana, e hōʻemi i ka paʻakikī deformation i ka aila, no ke kaʻa alakaʻi kiʻekiʻe, e hōʻemi i ka deformation. o ke kinoea nitriding a i ole plasma nitriding, a pela aku;

(C) Kiekie paakiki nui huinahalike a me ka rectangular paipu me ka pili ana luhi haawe, pono ia he kiʻekiʻe paakiki, a no laila, e paakiki, a paakiki a me kemika lapaʻau wela, a me ka tempering kaʻina.
