S890Q Cov Ntawv Qhia Ua Hlau
1. Kev npaj txiav thiab ntug
S890Q tuaj yeem ua tiav siv thermal thiab mechanical txiav txoj kev.
Thermal Cutting: nplaim taws (oxy- roj), ntshav, thiab laser txiav yog tsim nyog.
Preheating: Rau phaj thicknesses siab tshaj 30 hli, preheating rau 100℃-200℃yog pom zoo kom tiv thaiv kom txhob txias cracking ntawm cov npoo.
Ntug Zoo: Vim nws lub zog siab, laser txiav yog qhov zoo dua rau qhov tseeb thiab txo qhov kub ntawm qhov cuam tshuam (HAZ), uas pab tswj kev qaug zog.
Mechanical Cutting: Sawing lossis waterjet txiav yog qhov zoo tagnrho rau kev zam kom tsis txhob muaj kev cuam tshuam thermal ntawm cov khoom siv microstructure.
2. Vuam (Cov txheej txheem tseem ceeb)
S890Q muaj qhov zoo weldability, tab sis cov txheej txheem hauv qab no yog qhov tseem ceeb los tiv thaiv softening thiab tawg:
Thaum tshav kub kub input: yuav tsum nruj me ntsis txwv (feem ntau 5-25 kJ / cm). Kev siv hluav taws xob ntau dhau yuav ua rau cov qauv tempered martensite kom muag muag, txo cov khoom siv zog hauv thaj tsam weld.
Preheating: Tsim nyog rau cov phaj tuab lossis siab - cov pob qij txha txwv. Lub preheat thiab interpass kub ntau yam yog 100℃mus rau 225 degree.
