1. a float glass manufacturing device, this float glass manufacturing device forms glass ribbon by supplying melten glass continuously to the liquid level of molten metal, and this glass ribbon is advanced along above-mentioned liquid level, wherein,This float glass manufacturing device possesses:

  • multipair top roll main body, and they are for supporting the width end of above-mentioned glass ribbon;

    Multiple row well heater, they are arranged on the heater area of the regulation of the top of above-mentioned glass ribbon, and these well heaters are configured to rectangular at the fore-and-aft direction of the throughput direction of above-mentioned glass ribbon and width;

    Multiple controller,Above-mentioned heater area is arranged in multiple row along the throughput direction of above-mentioned glass ribbon;

    One or more by what each subregion of zoning on the above-mentioned width being respectively listed in above-mentioned glass ribbon is arranged respectively in above-mentioned well heater;

    Well heater in above-mentioned same subregion is controlled by with the above-mentioned controller unification that this subregion is arranged accordingly;

    Boundary between adjacent above-mentioned row is called segmentaion position,And between the immediate segmentaion position of rotation center of the above-mentioned top roll main body of most downstream and above-mentioned rotation center, be set within 80 centimetres along the distance of the throughput direction of above-mentioned glass ribbon,Subregion adjacent on the fore-and-aft direction of the throughput direction of glass ribbon in above-mentioned multiple row in consecutive plural row is arranged along the streamline of the regulation of above-mentioned glass ribbon,The streamline of the regulation of above-mentioned glass ribbon refers to the stream that the predetermined portion on the width of glass ribbon is passed through consistently,As the region of the streamlining Composition Region of the regulation along above-mentioned glass ribbon, be that the viscosity of the above-mentioned glass ribbon passed through from below is 10 5.3~ 10 5.7region within the scope of dPas.
