Nyob rau hauv thiaj li yuav txhim kho lub nto hardness thiab hnav tsis kam ntawmlub cev, nws tuaj yeem ua tiav qee qhov saum npoo, piv txwv li saum npoo ntawm cov nplaim hluav taws ntshiab, siab, nruab nrab zaus nto hardening thiab qee cov tshuaj kho mob thiab lwm yam.Feem ntau siab, nruab nrab zaus nto hardening feem ntau, nws yog rhuab ntawm ib tug kub ntawm 850-950℃.Muab nws cov thermal conductivity tsis zoo, yog li cov cua kub ceev tsis ceev heev, txwv tsis pub nws yuav yaj nrog qee qhov tsis xws luag quenching tawg.Induction hardening yuav tsum Rectangular Pipe normalizing matrix lub koom haum yog pearlite.Cov dej txias los yog cov tshuaj aqueous ntawm polyvinyl cawv, tempering kub ntawm 200-400℃, hardness 40-50HRC, hardness thiab hnav tsis kam los xyuas kom meej Rectangular yeeb nkab nto.

Rectangular yeeb nkab kev kho cua sov kuj muaj peb qhov zoo hauv qab no:

(A) High dimensional stability rau precision rectangular yeeb nkab, uas yuav tsum tau high precision, nws yuav tsum tau kom muaj qhov ntev stability, vim hais tias lub tsev kawm ntawv ncaj qha nyob rau hauv cov huab cua, qhov cua txias yog qeeb, yog li lub luag hauj lwm ntawm austenite muaj stabilized yuav ua rau kom cov nyiaj khaws cia. austenite cov ntaub so ntswg rectangular yeeb nkab, nws yuav tsum tau kho txias;

(B) Txo quenching distortion vim lub elongated square thiab rectangular raj, yog li txheej txheem hardened yooj yim deformed, nws yuav tsum nruj me ntsis tswj deformation, kev kho cua sov yog ib qho tseem ceeb kauj ruam nyob rau hauv lub quenching txheej txheem, siv cov yas yuav supercooled austenite raws sij hawm sib dhos, uas yog cov kauj ruam tseem ceeb los xyuas kom meej lawv cov kev sib haum xeeb, uas yuav tsum tau da dej kub quenching los yog txias cua sov ncaj qha rau qee lub sij hawm thaum cua sov yuav tsum tau dai rau ntawm cov cua sov, kom txo tau cov deformation hardening nyob rau hauv cov roj, rau high-precision qhia rail, txo cov deformation. ntawm cov roj nitriding lossis plasma nitriding, thiab lwm yam;

(C) High hardness main square thiab rectangular tube withstand fatigue loads, nws yuav tsum muaj ib tug siab hardness, thiab yog li ntawd yuav tsum tau hardening, los yog hardening los yog tshuaj kho cua sov, ua raws li los ntawm tempering txheej txheem.
