Process and apparatus for the production of mineral threads

摘要

Techniques for obtaining inorganic fibres from a thermoplastic material of high melting point and more precisely the control of the flow rate and of the temperature of the jet of molten material distributed on the fibre-making machine. The invention proposes to make the molten material pass through a storage chamber where a control of the flow rate and also a check on the height of molten material vertically above the casting orifice are performed using the inclination of the storage chamber. The invention applies to the production of rock wool.
