Alloy cast steel rolls
Ano ang Alloy Cast Steel Rolls?
Ang alloy cast steel rolls ay mahalaga sa mga modernong rolling mill, na nagbibigay ng mataas na lakas, tibay, at mahusay na resistensya sa pagsusuot. Ginagawa mula sa alloyed steel at mga elemento tulad ng chromium, nickel, at molybdenum, ang mga roll na ito ay nagbibigay ng mataas na thermal stability at mahabang buhay ng serbisyo.
Pangunahing Benepisyo
- Natatanging kakayahan sa pagdadala ng load
- Pinahabang resistensya sa pagsusuot para mabawasan ang downtime
- Maaasahang resistensya sa thermal fatigue
- Versatility para sa hot strip mills, plate mills, at section mills
