Inqubo yokwelapha ukushisa – normalizing

I-Normalizing, eyaziwa nangokuthi i-normalizing, inqubo yokwelapha ukushisa kwensimbi lapho i-workpiece ishiselwa ku-30 ​​~ 50 ° C ngaphezu kwe-Ac3 noma i-Accm, futhi ngemva kokubamba isikhathi esithile, ikhishwa esithandweni futhi ipholiswe ngamanzi. , fafaza noma uphephetha. Umehluko phakathi kokujwayelekile kanye nokufakwa kwe-annealing ukuthi izinga lokupholisa lokujwayelekile lishesha kancane kunelo lokudonsa, ngakho-ke isakhiwo esijwayelekile singcono kunesakhiwo sokudonsa, futhi izici zaso zomshini nazo ziyathuthukiswa. Ngaphezu kwalokho, ukupholisa kwangaphandle kwesithando somlilo esijwayelekile akuthathi imishini, futhi ukukhiqiza kuphezulu. Ngakho-ke, i-normalization isetshenziswa ngangokunokwenzeka ukufaka esikhundleni se-annealing ekukhiqizeni.

Izindawo eziyinhloko ezisetshenziswayo zokujwayela yilezi: ① Ngensimbi enekhabhoni ephansi, ubulukhuni ngemva kokujwayela buphakeme kancane kunobokubamba, futhi ukuqina nakho kungcono, okungasetshenziswa njengendlela yokwelapha kusengaphambili ukusika. ②Ngensimbi ye-carbon steel, ingasetshenziswa njengokwelashwa kokushisa kokugcina esikhundleni sokucisha kanye nokwelashwa kokushisisa, noma njengendlela yokwelapha yokulungiselela ngaphambi kokucinywa kwendawo ngokushisisa okungeniswayo. ③Isetshenziselwa insimbi yamathuluzi, insimbi ethwalayo, insimbi yensimbi, njll., inganciphisa noma ivimbele ukwakheka kwenethiwekhi ye-carbide, ukuze kutholwe isakhiwo esihle esidingekayo ukuze kufakwe i-spheroidizing annealing. ④ Ngokulingisa kwensimbi, ingacolisa ukwakheka kwe-as-cast futhi ithuthukise ukusebenza komshini. ⑤ Ukuze uthole ama-forging amakhulu, angasetshenziswa njengokwelashwa kokushisa kokugcina ukugwema ukuthambekela okukhulu kokuqhekeka ngesikhathi sokucisha. ⑥Isetshenziselwa i-ductile iron ukuthuthukisa ubulukhuni, amandla nokumelana nokuguga, njengokwenza izingxenye ezibalulekile ezifana nama-crankshaft nezinduku zokuxhuma zezimoto, ogandaganda nezinjini zikadizili. ⑦ Ukujwayela okukodwa ngaphambi kwe-spheroidizing annealing ye-hypereutectoid steel kungasusa usimende osukiwe ukuze kuqinisekiswe ukuthi yonke usimende i-spheroidized ngesikhathi sokukhishwa kwe-spheroidizing.
