Abstract: The heating temperature is an important technological parameter that affects the microstructure, mechanical properties and scale-resistant properties of hot rolled enamel steel. The microstructure, mechanical properties and scale-resistant properties of a hot-rolled titanium-containing enamel steel at different heating temperatures were studied. The microstructures were characterized by optical microscopy and transmission electron microscopy. While the mechanical properties and scale-resistant properties were evaluated by uniaxial tensile test and hydrogen permeation test, respectively. The results show that the microstructures of the experimental steel after hot rolling are both ferrite and carbides at heating temperatures of 1150 ℃ and 1250 ℃, and the average ferrite grain size and mean size of TiC particles decrease with the heating temperature increasing. The high heating temperature（1250℃） is beneficial to improve the yield strength, tensile strength and scale explosion resistance of hot-rolled titanium-containing enamel steel compared to the low heating temperature（1150℃）, and to obtain more fine ferrite and TiC precipitates during hot rolling.
