Furnace structure of glass melting furnace For large float lines, the glass furnace usually consists of an L-shaped hanging wall (usually using silica bricks), a melting section (the area in direct contact with the glass liquid should use electric fused bricks, and the The top part uses silica bricks or fused bricks), the clamping neck (usually uses silica bricks), the cooling part includes the ear pool (corundum materials are usually used in places that are in direct contact with the glass liquid, and silica bricks are used in places that are not in direct contact with the glass liquid) or corundum), annealing kiln, regenerator (composed of high alumina bricks, clay bricks, direct bonded magnesia chromium bricks) and other parts.
The structure of the glass furnace and the selection of refractory bricks for each part of the furnace 1. The top of the melting part and the cooling part of the glass melting furnace (including the arch angle). These parts are at a working temperature of 1600 degrees Celsius. The refractory bricks used in these parts are Refractory materials must be able to withstand high temperatures and loads as well as the erosion of alkali vapor and batch materials. Therefore, the refractory materials used as the top must have extremely high refractoriness, high load softening temperature and good creep resistance. , and the thermal conductivity is small, the refractory material at high temperature cannot pollute the glass liquid, the bulk density of the material should also be small, and it has good high temperature strength and other characteristics.
