Device for simulating float glass forming

The utility model belongs to the technical field of float glass production, and provides a device for simulating float glass forming. The device for simulating the float glass forming comprises a hollow quartz glass tube (1) of which one end is opened and the other end is closed, wherein a graphite cuvette (2) is placed in the quartz glass tube (1) and is provided with mutually communicated material placing tank I (10) and a material placing tank II (11), the bottom surface of the material placing tank I (10) is a plane, and the bottom surface of the material placing tank II (11) is an inclined plane inclining from top to bottom; a raw glass sheet (12) is placed in the material placing tank I (10), and a tin block (13) is placed in the material placing tank II (11); a pipe orifice plug (3) is arranged at the opened end of the quartz glass tube (1); and an air inlet pipe (4), an air outlet pipe (6) and a pressure measuring pipe (8) are arranged on the pipe orifice plug (3). The device provided by the utility model can be used for tests of simulating the pressure of a molten tin bath, and protective gas ratio, temperature parameters and the like, and has a very practical significance for improving the float glass quality.
