Abstract
The subject invention is directed to a method for producing a pre-reacted clinker used in the manufacture of E glass. The clinker is fed into an E glass furnace, and melts down into a finished E glass product at high efficiencies and short production times. The clinker allows glass to be produced at a lower cost as compared with known methods.
Claims17
A method for preparing a pre-reacted pellet for the formation of glass fibers comprising:
- feeding raw materials into a pre-react kiln;
- heating said raw materials at a temperature of from 900° C. to about 1250° C. for a period of from about 1 to about 24 hours so as to remove carbonates from said raw materials;
- and
- forming said raw materials into a pellet.
1 more element
A method for preparing a pre-reacted pellet for the production of glass comprising:
- preparing a mixture of raw materials;
- forming the mixture of raw materials into pellets;
- and
- heating the pellets in a pre-react kiln at a temperature of from 900° C. to about 1250° C. for a period of from about 1 to about 24 hours to remove carbonates from the raw materials.
1 more element
A method for preparing glass comprising:
- forming a raw material mixture;
- heating the mixture at a temperature of from 900° C. to about 1250° C. for a period of from about 1 to about 24 hours such that carbonates are removed from at least a portion of said raw materials;
- forming said raw material mixture into pellets;
- melting said pellets to form a molten glass;
- and
- forming said molten glass into a glass product.
