This invention provides a glass melt conveying device and its temperature control method, comprising an inner wall, an outer wall, and a cavity disposed between the inner and outer walls; both the inner and outer walls are made of refractory materials; the surface of the inner wall is provided with an anti-erosion layer; multiple inner wall temperature detectors are uniformly arranged in the inner wall; the outer sides of the two walls of the cavity are respectively attached to the inner and outer walls; multiple supports are uniformly arranged in the cavity; the two ends of the supports are respectively fixed to the inner sides of the two walls of the cavity. This invention can achieve a heat preservation effect on the bottom and sides of the glass melt through the anti-erosion layer, preventing related defects caused by temperature differences. At the same time, using non-precious metals such as molybdenum as the anti-erosion layer to prevent the glass melt from eroding greatly reduces construction costs; for platinum tube-type glass melt conveying devices, molybdenum electrode heating can be used instead of platinum heating in the high-temperature section, eliminating the situation where the entire channel is electrified, thereby improving production safety.
