The history of making glass bottles is too long. The production process of making bottle is as follows: the glass melting furnace supplies material to two production lines in the same time, which include the feeder channel, the feeder machine, and the making-bottle machine. The entrance of the two feeder is connected to the exit of glass liquid in the glass melting furnace, and the entrance of the feeder channel is connected to feeder spout and the exit of the spout is connected to the  bottle making machine through the orifice ring, Due to the influence of height difference, the glass liquid in the glass melting furnace naturally flows into the spout.

For the sillimanite spout, after the physical effoects and the chemical erosion of the glass liqure, the factory will change the spout within 8months. If the spout cant change in time, some safe problem will happen. When changing the spout, in the feeder channel, the glass liqure should be steady in the height as the normal production because only in this height, there is much glass liqure in the feeder channel and spout, When close the entrance of the feeder channel, need use much broken glass and it is very difficult to change the pout. When finish the spout, need let the broken glass melted and leave. When melting the broken glass, it will take more time to change the spout and in this way, it will take about 20 hours to change the spout. And if operate wrongly, will cause the bad effort.

AZS spout brick is a common material in the glass industry. For to fix the spout well, the main body of the spout brick is been designed perfectly.The details are as following:

The main body is the material pot brick for an electric melting glass furnace proposed as a rectangular prism with a convex surface on the left end and the cross-sectional shape of the convex surface on the left end of the main body is trapezoidal;.The top surface of the protrusion is a sloping plane that slopes downwards from right to left. A flow channel with a through groove structure in the middle of the upper end face of the body . The through-hole has a glass liquid inlet groove , a rectangular groove, and a glass liquid outlet groove  that are connected from right to left; The glass liquid inlet groove is a trapezoidal open groove; The four corners of the rectangular groove are all rounded corners ; The glass liquid outlet groove  is a U-shaped axial groove that runs through the top surface of the convex platform; The outlet end of the U-shaped axial groove is a curved surface. This utility model has the characteristics of reasonable structure, no dead corners, less pollution to glass liquid, good corrosion resistance, long service life, and convenient molding. The type has the characteristics of reasonable structure, no dead corners, less pollution to glass liquid, good corrosion resistance, long service life, and convenient molding.
