Khoom Description
Z steel phaj yog ib qho ntawm cov khoom tseem ceeb ntawm peb lub tuam txhab, peb paub tias cov phaj tuab dav dav yog feem ntau ua rau lub laminar tsim kua muag, vim tias cov hlau phaj tuab dua, ntau cov hlau tsis xws li cov hlau tsis xws luag, thiab qhov tuab ntawm cov vuam, qhov ntau dua qhov vuam kev nyuaj siab thiab deformation. Yog li ntawd, txhawm rau daws qhov teeb meem no, Z-oriented steel daim hlau yuav tsum tau siv kom deb li deb tau.
Cov ntsiab lus ntawm leej faj nyob rau hauv thawj molten hlau tuaj yeem txo qis, cov ntsiab lus sulfur hauv cov hlau molten siv los tsim Z-directional steel phaj tuaj yeem tswj tau hauv qab no 0.005 feem pua , thiab cov sulfur tuaj yeem raug desulfurized los ntawm LF refining.
Cov yas MnS suav nrog hauv cov hlau tuaj yeem hloov mus rau hauv cov khoom tsis yog yas kheej kheej CaS suav nrog lossis ob theem kev suav nrog tsim los ntawm cov calcium aluminate siab thiab CaS nrog cov muaj peev xwm sulfur siab kom tsis txhob tsim cov saw hlau MnS yas inclusions, uas yog qhov zoo rau kev txhim kho Z-kev taw qhia cov khoom ntawm cov hlau.
Quenching thiab tempering yog hais txog kev sib xyaw ua ke ntawm quenching thiab kub tempering, los yog nruab nrab kub tempering los yog normalizing tshav kub kho. Lub hom phiaj yog ua kom tus choj Z-directional phaj ua tiav kev ua tau zoo dua. Quenching thiab tempering yog tsuas yog siv rau nruab nrab carbon steel thiab alloy steel daim hlau. quenching thiab tempering kev kho mob Tom qab quenching, ib co choj Z-phaj nrog kev ntxhov siab ntau dua yuav tsum tau tempered nyob rau hauv lub sij hawm kom tsis txhob tawg. Rau qhov kub-kub tempering ntawm quenching thiab tempering kho, qee cov hlau phaj yuav tsum tswj kom txias ceev kom tsis txhob tempering embrittlement.
