The invention discloses an enamel glaze with good adherence to a steel plate. The enamel glaze is prepared from the following components in percentage by weight: 50-65% of SiO2, 20-30%of Al2O3, 4-15% of B2O3, 1.2-1.5% of Na2O, 1.3-1.6% of K2O, 1-10% of EuO2 and 2-5% of EuF3. The EuO2 and the EuF3 are added to a conventional enamel glaze, so that the hardness of the glaze and the adherence to the steel plate can be improved and scale detonation can be effectively prevented. 本发明公开了种与钢板密着性良好的搪瓷釉料，按重量百分比计，由以下组分构成：SiO50～65％、AlO20～30％、BO4～15％、NaO 1.2～1.5％、KO 1.3～1.6％、EuO1～10％、EuF2～5％。本发明在常规搪瓷釉料中加入EuO和EuF可以提高釉料的硬度以及与钢板的密着性，还能有效防止鱼鳞爆的发生。
