Embodiment 1
[0013] (1) Porcelain powder: 60% to 75%, antiknock agent: 0.5% to 2%, pigment: 1% to 3%, sodium nitrite (content: 98%): 0.15% to 0.35%, borax ( Content: 95%): 0.15% ~ 0.4%, calcium carbonate: 0.1 ~ 0.5%, kaolin: 4% ~ 5%, quartz powder: 3.6% ~ 5.5%, urea (nitrogen content: 46.4%): 0.5% ~ 1.5%, water: 27% ~ 45% mixed into the ball mill, after ball milling for 6 hours, to get the glaze;
[0014] (2) Spray the ball-milled glaze on the rust-removed steel plate, put it in the drying room to dry the glaze, and then fire at 900°C to obtain the enamel product.
Embodiment 2
[0016] (1) Porcelain powder: 65%, antiknock agent: 0.6%, pigment: 1.6%, sodium nitrite (content: 98%): 0.15%, borax (content: 95%): 0.25%, calcium carbonate: 0.1 %, kaolin: 4.6%, quartz powder: 3.6%, urea (nitrogen content: 46.4%): 0.7%, water: 30%, mix and add to the ball mill, after ball milling for 6 hours, the glaze is obtained;
[0017] (2) Spray the ball-milled glaze on the rust-removed steel plate, put it in the drying room to dry the glaze, and then fire at 900°C to obtain the enamel product.
