Qhov txawv ntawm kev kos duab txias thiab txias dov!
- Kev kos duab txias yog yuam kom kos cov kab hlau puag ncig los ntawm carbide hlau kos duab tuag qhov. Cov nyhuv ntawm kev kos duab txias yog muaj zog dua li ntawm cov duab ntshiab, thiab cov hlau bar tsis yog tsuas yog stretched, tab sis kuj squeezed. Cov khaub thuas- kos qis carbon steel hlau tau txais tom qab ib lossis ntau qhov txias txias tuaj yeem ua rau nws cov ntsiab lus tawm los ntawm 40% mus rau 60%, tab sis nws poob lub plasticity thiab toughness ntawm cov hlau mos, thiab muaj cov yam ntxwv ntawm cov hlau tawv.
- Txias dov yog dov puag ncig steel rau hauv steel bar nrog ntu zoo li lub tshuab txias dov, uas tuaj yeem txhim kho nws lub zog thiab adhesion nrog pob zeb. Thaum lub sij hawm txias dov, lub steel bar deforms ob longitudinally thiab tom qab, thiaj li hais tias nws plasticity thiab internal qauv uniformity yuav tswj tau.
