Abstract

PURPOSE:Wires of Mo alloy are knitted to form a hopper for melting glass and it is used, as it is cooled on its outside surface with an inert gas, thus preventing errosion at elevated temperature and melting glass in low costs. CONSTITUTION:Wires, ribbons or bands of Mo are knitted to form a cylindrical cage (hopper) 3 provided with inlet 2 and outlet 5. The cage is put in the box 7, as the outside of the inlet 2 and the outside 4 of the outlet 5 are tightly closed, then an inert gas is fed from inlet 71 and exhausted from the outlet 72. Glass is charged in the basket 1l and melted with electrodes 8 for heater to form melt 92 and the outside glass 91 adjacent to the basket is solidified by cooling with the inert gas to take the melted glass 92 out of the outlet 5 with no troubles. Consequently, the knitted basket of Mo (hopper) is protected by the solidified glass 91 to prevent errosion to effect glass melting.

Therefore, there are two problems to be solved by the present invention. In the present invention, a woven basket is made from molybdenum wire, and then it is placed in a cooled argon gas. The glass in the woven basket is cooled, whereby the temperature of the glass itself decreases and becomes solidified. This solidified material is the outer surface of the glass in contact with the woven basket. . Then, by heating the inside crow to a molten state and taking out the molten state inside, it can be used as the woven basket hopper. And the outer glass
Because it is cooled in an inert gas such as argon gas,
The molybdenum wire is well protected and will not be eroded.

If the woven basket No. 1 is large, it is possible to fabricate a framework made of ceramic material No. 6 as shown in Fig. 2 and install the knitting platform No. 1 within it. As for the ceramic material (6), the glass in contact with the woven basket (2) is kept at a low temperature by cooling with inert gas from the outside, so it will not be corroded. 3 and 4 show an example of the method of using the present invention. FIG. 3 is a perspective view, and FIG. 4 is a sectional view. A box 7 is in contact with the outer periphery of the hopper 1 without any gaps and can maintain a sealed state. 71 and 72 are ports for supplying inert gas and ports for discharging a small amount of gas. By this cooling inert gas, the outer glass 91 in contact with the molten glass knitting platform is cooled and solidified. Even if the glass is in the sealed box 7, it is possible to take out the glass from the entrances and exits 2 and 4 without any problem. 8 is an electrode rod for electrical heating. Thereby, the glass inside the hopper 92 can be heated to a high temperature and can be maintained at a high temperature.
