Cov Lus Qhia Tseem Ceeb
S235JR yog cov hlau tsis yog hlau uas siv dav hauv kev tsim kho thiab kev tsim khoom.
Cov hlau kub dov muaj cov weldability zoo thiab formability.
Qib "JR" qhia txog kev sim cuam tshuam ntawm chav tsev kub (20 ° C).
Peb licov hlau kaum sab xisraug tsim tawm raws li kev tswj hwm zoo: cov khoom siv raw zoo raug tshuaj xyuas ua ntej thiab tom qab ntawd cua sov thiab dov ntawm 1200-1300 ° C rau hauv cov duab sib npaug / tsis sib npaug L. Tom qab tswj kev txias thiab ncaj, cov khoom raug txiav rau hauv tus qauv 6/9/12-meter ntev. Qhov chaw raug ntxuav thiab kho nrog cov txheej tiv thaiv xeb. Txhua pawg tau dhau los ua kev tshuaj xyuas tshuaj lom neeg, tshuab, thiab qhov ntev kom ua tau raws li cov qauv cuam tshuam. Thaum kawg, kev khi ruaj ntseg / pallet ntim khoom ua kom muaj kev thauj mus los thoob ntiaj teb zoo.
Zoo heevcov hlau kub dov lub kaum sab xissiv dav thoob plaws kev tsim kho, kev lag luam, thiab kev tsim khoom vim lawv qhov kev sib txuas zoo heev, kev ua tau zoo, thiab kev siv nyiaj tsim nyog.
