Q690 HW CARBON STEEL H BEAM yog noncombustible, nws tsis hluav taws kub. Thaum qhov kub nce mus txog 600 degree, cov hlau yuav plam feem ntau ntawm nws lub zog thiab nruj. Yog li ntawd, ib zaug hluav taws tshwm sim hauv lub tsev steel, cov qauv yooj yim yuav raug puas los yog txawm tawg [1]. Cov kev hloov pauv hauv cov khoom siv ntawm cov qauv hlau vim hluav taws kub yog feem ntau cuam tshuam rau ob yam: lub zog thaum hluav taws thiab tom qab hluav taws. Thaum cov qauv hlau raug hluav taws kub, qhov kub ntawm cov qauv hlau yog qhov siab.
