Problems solved by technology
As the use time of sidewall bricks and supporting bricks increases, the crystallization area becomes wider and wider, and the frequency of manual crystallization becomes higher and higher, which will seriously affect production. Generally, it can only be replaced by replacing the calender after 20-30 days of use. Solve the crystallization problem
It usually takes 10 to 15 hours from the replacement of the calender to the normal production, which has a great impact on production

Abstract
The embodiment of the invention provides a novel edge blocking brick and a supporting brick for a glass pressing machine, wherein the edge blocking brick for the glass pressing machine comprises an edge blocking brick main body made of a refractory material and an oxidation resisting graphite layer; and the oxidation resisting graphite layer is located on the side surface, facing a molten glass, of the edge blocking brick main body, and is used for isolating the molten glass from the edge blocking brick main body. The supporting brick for the glass pressing machine comprises a supporting brickmain body made of a refractory material and an oxidation resisting graphite layer; and the oxidation resisting graphite layer completely covers the upper surface, facing the molten glass, of the supporting brick main body, and is used for isolating the molten glass from the supporting brick main body.
Description
technical field [0001] The invention relates to the technical field of glass production equipment, in particular to a novel edge retaining brick and supporting brick for a glass calender. Background technique [0002] The glass calendering process is a commonly used glass forming process; in the glass calendering process, the glass calender is a forming unit, which is mainly used to squeeze the molten glass from the kiln through the upper and lower calender rollers and cool it rapidly, and finally Formed into glass sheets. The end of the glass calender connected to the furnace is provided with sidewall bricks and supporting bricks, which are used to control and adjust the thickness, width and other parameters of glass plates of different specifications. [0003] The side retaining bricks and supporting bricks commonly used in enterprises are made of refractory materials such as sillimanite or zircon mullite. The surface of these refractory materials is relatively rough, and...
