[0002] Typically, the cut, edge-grinded, and cleaned flat glass is transported to a heating furnace according to certain requirements and heated by a reciprocating motion. Resistance wires in the upper and lower furnace chambers directly irradiate both sides of the glass. Temperature control elements are installed in the upper and lower chambers, and a heat balance tube is installed in the upper chamber. Low-E molten-glass is primarily used in the field of ordinary float glass. Various functional molten-glass is sputtered onto one side of ordinary float glass in an online or offline manner to form a molten-glass. However, ordinary heating methods cannot meet the processing requirements of Low-E molten-glass. Low-E molten-glass has extremely high reflectivity, and using ordinary infrared heating methods, the heat is not easily absorbed, resulting in low heating efficiency. Utility Model Content
