Normalizing Basics Thaum lub sij hawm normalizing, hlau yuav tau rhuab mus rau qhov kub thiab txias heev, tab sis tom qab ntawd tso cai rau ib txwm txias rov qab rau hauv chav tsev kub los ntawm kev raug rau theem ntawm huab cua ncaj qha tom qab cua sov. Cov txheej txheem no tso cai rau cov qauv ntawm cov hlau nws tus kheej hloov pauv.
Cov cua kub ntawm cov hlau yog dab tsi thaum lub sij hawm normalizing?
Qhov normalizing ntawm hlau (Fig. 2) yog ua los ntawm cua sov kwv yees li 100 ° F (38 ° F) saum toj qhov ntsuas kub tseem ceeb(Ac3 lossis Acm) ua raws. cua txias hauv huab cua mus rau chav tsev kub, lossis tsis muaj siab tshaj ib-bar siab siv nitrogen yog tias cov txheej txheem tau khiav hauv lub tshuab nqus tsev.
Yuav ua li cas thaum koj normalize steel?
Normalizing suav nrog cua sov cov hlau mus rau qhov kub siab, ua raws li qhov txias txias rau chav sov. Cov cua kub thiab txias qeeb hloov cov microstructure ntawm cov hlau. Qhov no txo cov hardness ntawm cov hlau thiab yuav ua rau nws ductility.
Yuav ua li cas steel Normalised?
Normalising yuav cua sov cov khoom mus rau qhov kub siab thiab tom qab ntawd cia nws txias rov qab rau hauv chav sov los ntawm kev nthuav tawm rau hauv chav tsev kub tom qab nws rhuabQhov cua sov no thiab qeeb qeeb Hloov cov microstructure ntawm cov hlau uas nyob rau hauv lem txo nws hardness thiab tsub kom nws ductility.
Vim li cas tempering ua tiav tom qab normalizing?
Cov hlau no feem ntau yog tempered tom qab normalizing, txhawm rau ua kom tawv nqaij thiab txo cov kev ntxhov siab sab hauv. Qhov no tuaj yeem ua rau cov hlau haum rau nws txoj kev siv thiab yooj yim rau tshuab.
