Advantage of ceramic wool insulation in glass annealing equipment

The use of ceramic wool insulation products instead of asbestos boards and bricks as the lining and thermal insulation material of the glass annealing furnace has many advantages:

ceramic-wool-insulation

1. Due to the low thermal conductivity of ceramic wool insulation products and good thermal insulation performance, it can improve the thermal insulation performance of annealing equipment, reduce heat loss, save energy, and is beneficial to the homogenization and stability of the temperature inside furnace.
2. Ceramic wool insulation has a small heat capacity (compared with insulation bricks and refractory bricks, its heat capacity is only 1/5~1/3), so that when the furnace is restarted after the furnace is shut down, the heating speed in the annealing furnace is fast and the heat storage loss is small , Effectively improve the thermal efficiency of the furnace. For intermittent operating furnace, the effect is even more obvious.
3. It is easy to process, and it can be cut, punched and bonded together at will. Easy to install, light in weight and somewhat flexible, not easy to break, easy to place in places that are difficult for people to access, easy to assemble and disassemble, and long-lasting heat insulation at high temperatures, so that it is convenient to quickly replace rollers and check heating and temperature measurement components during production, reduce the labor work of furnace building installation and furnace maintenance, and improve workers’ working conditions.
4. Reduce the weight of the equipment, simplify furnace structure, reduce structural materials, reduce the cost, and extend the service life.
Ceramic wool insulation products are widely used in industrial furnace linings. Under the same production conditions, furnace with ceramic wool insulation linings can generally save 25-30% compared with brick furnace linings. Therefore, introducing ceramic wool insulation products into the glass industry and applying them to glass annealing furnace as linings or thermal insulation materials will be very promising.
