Kuti uvandudze kuoma kwepamusoro uye kupfeka kusagadzikana kwerectangular pipe, inogona kugadziridzwa imwe pamusoro, kureva pamusoro pemurazvo wakachena wemoto, wakakwira, wepakati frequency kuomarara uye kumwe kurapwa kwemakemikari nezvimwe zvakadaro.Kazhinji yakakwira, yepakati frequency kuomarara kwevazhinji, inodziya pakupisa kwe850-950.℃.Zvichipa ayo murombo chokupisa conductivity, saka kudziyisa kumhanya hakusi kukurumidza, zvikasadaro zvichanyunguduka nevamwe kuremara quenching makatsemuka.Induction kuomesa zvinodiwa Rectangular Pipe normalizing matrix sangano inonyanya pearlite.Iyo inotonhorera yekupfapfaidza mvura kana ine aqueous solution yepolyvinyl doro, kupisa tembiricha iri pakati pe200-400.℃, kuoma 40-50HRC, kuoma uye kupfeka kuramba kuti ive nechokwadi Rectangular Pipe pamusoro.

Rectangular pombi kupisa kurapwa zvakare ine zvinotevera zvinotevera zvakanaka:

(A) Yakakwirira dimensional kugadzikana kweiyo chaiyo rectangular pombi, inoda kurongeka kwepamusoro, inofanirwa kuchengetedza kugadzikana kwedimensional, semhedzisiro chikoro chakananga mumhepo, kutonhora kuri kunonoka, saka basa reaustenite radzikama richawedzera huwandu hwekuchengetwa. austenite tishu rectangular pombi, inofanira kutonhora kurapwa;

(B) Deredza kudzima kukanganisa nekuda kweiyo elongated sikweya uye rectangular chubhu, saka yakaomeswa maitiro nyore kuremara, inofanira kunyatsodzorwa deformation, kupisa kurapwa inhanho yakakosha mukudzima maitiro, kushandiswa kwepurasitiki kuve supercooled austenite kurongeka panguva. nhanho yakakosha yekuve nechokwadi chekuenderana kwavo, iyo inofanirwa kunge iri kupisa yekugezesa kudzima kana kutonhora kururamisa kupisa kunotsanangurwa imwe nguva apo kupisa kunofanirwa kusungirirwa pakupisa, kuderedza deformation kuoma mumafuta, kune yakakwira-chaiyo njanji, kuderedza deformation. yegesi nitriding kana plasma nitriding, nezvimwewo;

(C) High kuoma main square uye rectangular chubhu kutsungirira kuonana kuneta mitoro, inofanira kuva yakakwira kuoma, uye saka inofanira kuomesa, kana kuomesa kana kemikari kupisa kurapwa, kuchiteverwa tempering muitiro.
