To enhance the adhesion performance of acid-pickled enameled steel, the factors influencing its adhesion performance were studied, including enameling time, degreasing efficiency, surface color difference and surface roughness. Samples with varying degrees of degreasing, surface states and roughness were coated and enameled. The adhesion performance was then evaluated using the falling ball impact method. Re-sults showed that when enameling was performed at 850 ℃, extending the enameling time from 5 to 10 min improved the adhesion grade from level 2.0 to 1.0. Additionally, at 5 min of enameling, insufficient degreasing, increased carbon from protective slags causing color differences and reduced roughness all decreased the adhesion performance between the steel plate and the enamel glaze. While the effects of insufficient de-greasing and color differences could be mitigated by extending the enameling time to 10 min, the impact of roughness on adhesion performance remained significant even with extended enameling time.
