Cov xwm txheej tsim nyog rau kev xaiv furnace cov ntaub ntawv

Dab tsi yog qhov tsim nyog rau kev xaiv furnace cov ntaub ntawv raws li ntau xyoo ntawm kev ua haujlwm ua haujlwm? Teb:

1. Ua ntej tshaj plaws, cov khoom siv hauv ob sab phlu tsis deform lossis yaj ntawm qhov kub txaus.

2. Nws tuaj yeem muaj lub zog tsim nyog ntawm qhov kub thiab txias yam tsis muaj softening deformation

3. Lub ntim yuav tsum ruaj khov ntawm qhov kub thiab txias, yog li nws yuav tsis nthuav thiab ntsws kom ua rau tawg

4. Thaum qhov kub thiab txias hloov pauv los yog cua sov tsis sib xws, nws yuav tsis tawg thiab tev tawm

5. Nws tuaj yeem tiv taus cov tshuaj tua hluav taws xob ntawm cov tshuaj hlau, slag thiab cov roj cua sov
