First of all, the standard of steel plate used for enamel bolted panels of bolted tanks:

The specifications of the steel plates are thickness 2.0~12.0mm; width 1250mm; length 2500mm. The content of elemental copper should not exceed 0.15%.

Secondly, the enameling process of the enamel bolted board generally adopts the wet two-coating and two-firing process. The enamel frit needs to choose a special industrial enamel frit according to the acid and alkali resistance. The firing temperature of the enamel ground coat is controlled at 840~900℃, and the firing temperature of the enamel cover coat is controlled at 820~880℃. The firing time is determined according to the thickness of the steel plate.

Finally, the bolted board is installed on the enamel bottled tank. According to the cutting angle of the steel plate, install the first layer plate, the top plate of the tank body, and install accessories such as 90° stirrups, tank body lightning rods, and folded plate pressing plates. Fix the installed top-level bolted board to the lifting equipment, turn on the geared motor, and lift the top-level board by 1.25~1.3m. According to the installation method of the top steel plate, install other layers of enamel bolted boards. During the installation process, the accessories according to the requirements of the drawings include the tank platform, the vertical ladder bracket, and the tank casing opening. In order to provide convenient and safe passage for the equipment in the tank, when installing the last board (the last board from top to bottom), one board should be left uninstalled, and the last board should be installed after all the equipment is installed. plate. After the tank body is installed, it is fixed with chemical anchor bolts.
