[0003] In the production of float glass, the raw materials are melted into a liquid state in a melting furnace, and the glass liquid flows into a tin bath through a runner and is laid flat and formed in the tin bath. The drawing rate, that is, the flow rate of the glass liquid flowing into the tin bath, is determined by the height of the runner gate and the flow rate of the glass liquid. Unstable drawing rate will directly affect the quality of glass production.
