The production process of glass cans mainly includes pre processing of raw materials. Crush blocky raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry wet raw materials, and remove iron from iron containing raw materials to ensure glass quality. Batch preparation and melting.
The glass batch is heated at a high temperature of 1550-1600 degrees Celsius in a tank or furnace to form a uniform, bubble free liquid glass that meets the molding requirements. Place liquid glass into a mold to make the required shape of glass products, such as flat plates, various utensils, etc., undergo heat treatment. By annealing, quenching, and other processes, stress, phase separation, or crystallization inside the glass can be eliminated or generated, as well as the structural state of the glass can be changed.
