glass ball for Christmas decoration


The glass ball is a raw material for the production of continuous glass fiber by using a sputum drawing furnace; while the kiln method of the kiln is directly used as a raw material for the production of the glass ball with its own production characteristics.

First, the manufacturing process of glass balls

The raw materials for the glass ball are mostly natural ore. Therefore, in order to manufacture the glass ball, various ores are first pulverized, processed into a powder, and then a batch is prepared according to the glass component, and sent to a glass melting furnace for melting to form a glass liquid. Qualified glass flows through the feed tank and exits the feed port to form a strand. The temperature of the stock, the medium alkali glass is generally 1150 to 1170 ° C, and the alkali-free glass is 1200 to 1220 ° C. The strands were cut into billets by nearly 200 times per minute. The ball blank passes through the chute and the ball splitter, and is moved by the ball dividing plate, respectively, rolled into different funnels, and then falls into a ball forming groove formed by three rollers having the same rotating direction. The ball blank rotates on the roller and its surface tension acts to gradually form a smooth round glass ball. The size of the diameter is determined by the thickness of the glass stream, the flow rate, and the speed of the scissors.

When the glass ball is away from the roller, the temperature is still very high. In order to prevent the ball from sticking, it needs to be cooled by the cold ball disk or the serpentine track. To reduce the residual stress generated by the temperature difference between the inside and outside of the glass ball, it needs to be annealed to slowly cool, then Stored in the ball compartment for quality inspection.
