Silicon carbide in the glass industry applications

A cooling section and all of paragraph
It is composed of two identical heating element with three cold end is welded using a special process, namely two indirect heating element in a cold end, the total length of the three corresponding channel width and material (in the import of the material Road dual threaded silicon carbide) Since the middle of silicon carbide less heat and no heat or heat near the side wall parts, coupled with reasonable design, we can ensure the flow of molten glass at uniform temperature drop. When the feed channel design, etc.fruit tree sprayer Some manufacturers also use the diameter silicon carbide (ie, three type silicon carbide), which is composed of a heating element and two cold ends welded together. Glass liquid flowing through the cooling and homogenization segment of the process, should be made uniform cooling of the molten glass to a temperature suitable for molding, if no measures are taken, Forehearth more heat on both sides, the middle parts of the less heat will cause the glass to the middle part and both sides of the larger temperature gradient, the temperature of the glass was the same uniform cross-section, the glass viscosity is inconsistent, directly affect the quality of the molding, the feed temperature to the same, while the cooling holes in the cooling section aside, by adjusting the cooling holes the opening degree of the cooling section to adjust the middle of the forehearth much heat, the temperature uniformity; other hand, the use of special silicon carbide auxiliary heating to achieve. Silicon carbide are generally evenly arranged inside the feed channel above the molten glass, the glass was kept a certain distance downwards radiant heating. Road on both sides in order to ensure material is not heated by heating the middle part, generally used in the glass industry-specific silicon carbide Forehearth five rods (ie dual silicon carbide heating element).
Whether used three rods or five rods, homogenizing effect by feeding channel structure and silicon carbide heating to decide, while Forehearth ultimately how much each segment by the control system to control the temperature. Forehearth use three silicon carbide silicon carbide on both sides of the glass wall of liquid heating also heated,household sprayer so to ensure that each segment forehearths temperature, can also play on the sidewall cooling complementary role, but nowhere near the homogenizing effect five silicon carbide
Glass flow through all of paragraph later, the temperature dropped to a proper value even if the temperature at the right spout not controlled, is still difficult to ensure there is a constant gobs uniform temperature, so temperature is too high or too low will affect the gob shape, and ultimately affect the quality of the glass container forming.
