Research and Practice of Technological Processes and Facilities of Refractory Fibre Manufactured in Resistance-heated Furnace

On the principle of correlation between the fluid movement and the viscosity, the flow rate of the melt through, the nozzle is determined by the viscosity of aluminium silicate melt which can be controlled to reach the goal of the continuous melting and blowing in the resistance furnace and to prolong the furnace campaign. After the special type of N-L composite nozzle was applied to the furnace , per ton refractory fibre costs is reduced by 579 Yuan and the productivity increases by 80% . The effect of energy saving is striking. After the innovation of continuous melting and blowing resistance furnace production line for the aluminium silicate fibre, annual production cost of 580,000 Yuan has been saved the furnace campaign life increases by 5- 8 times and the consistency and reliability of product quality have been greatly improved.
