Embodiment 1
[0030] Such as figure 1 Shown, a kind of production technique of enamelled steel plate of the present embodiment comprises the following steps:
[0031] Step 1. Forming: Cut the steel plate substrate to be processed into the desired shape; the steel plate substrate is first drawn by computer, and then cut into the desired shape by the laser cutting machine according to the digital data of the design drawing input by the computer , and then through the bending machine to make surface features such as face angles, side angles or arcs.
[0032] Step 2. Pretreatment: Chemically treat the formed steel plate substrate to remove pollutants and derust at the same time;
[0033] Step 3, bottom glaze spraying: spray bottom glaze on the steel plate substrate;
[0034] Step 4, drying: drying the base glaze on the steel plate base material sprayed with the primer at 100°C to 250°C to form a biscuit state;
[0035] Step 5. Furnace firing: Preheat the steel plate base material to 400°C, p...
Embodiment 2
[0047] A kind of production technology of enamelled steel plate of the present embodiment, comprises the following steps:
[0048] Step 1. Forming: cutting the steel plate substrate to be processed into the desired shape;
[0049] Step 2. Pretreatment: Chemically treat the formed steel plate substrate to remove pollutants and derust at the same time;
[0050] Step 3, bottom glaze spraying: spray bottom glaze on the steel plate substrate;
[0051] Step 4, drying: drying the base glaze on the steel plate base material sprayed with the primer at 100°C to 250°C to form a biscuit state;
[0052] Step 5. Furnace firing: Preheat the steel plate base material to 400°C, put it into an enamel firing electric furnace and heat it to 800°C, and fuse the enamel bottom glaze with the surface layer of the steel plate base material;
[0053] Step 6, surface glaze spraying: spray a layer of surface glaze on the steel plate substrate according to the required color;
[0054] Step 7, drying: d...
