However, due to insufficient temperature resistance and corrosion resistance of the manufacturing materials of traditional bowl body and material nozzle, it is difficult for them to withstand the scouring of high-temperature glass melt for a long time, and the bowl body and the material nozzle adopt an integrated structure design, so that the material nozzle needs to be replaced as a whole when it is locally damaged, which not only reduces the efficiency of large-scale production, but also leads to high overall production cost.

[0004] Patent CN1098219C discloses a preparation process of refractory product using high-silicon porous glass as raw material, and a glass material bowl that can withstand high temperature (1100℃) is prepared. However, due to the limitations of the silicon-oxygen material itself and the lack of protective structure design, the prepared material bowl still has unsatisfactory durability under the scouring of high-temperature glass melt.

[0005] Therefore, how to design a glass material bowl with high durability, corrosion resistance and controllable cost has become a technical problem to be solved in the field. UTILITY MODEL CONTENTS

Compared with the corrosion-resistant temperature-resistant layer, the metal plating layer is deposited on the inner wall of the material nozzle, the plating layer thickness is uniform and thin, which can reduce the equipment cost. Although the thickness of the corrosion-resistant temperature-resistant pipe is increased, it is convenient to process and assemble, and the interchangeability of each material bowl is stronger.

[0033] Preferably, the inner diameter of the flow channel portion is less than or equal to the inner diameter of the discharge pipe. The above design is beneficial to the guiding discharge of high-temperature glass material, and on the other hand, the structure of the corrosion-resistant temperature-resistant pipe can block the end portion of the discharge pipe to prevent high-temperature oxidation damage.
