Abstract
A device and method of reclaiming refractory material from a lining of a refractory includes assembling a first refractory component of the lining with a first refractory product, and assembling a second refractory component of the working lining with a second refractory product different from the first refractory product, the second refractory product including magnetic material dispersed therein. Upon the lining reaching a service life, the lining is demolished to produce a mixture of the first refractory component pieces and the second refractory component pieces. Magnetic separation is performed on the mixture to separate the second refractory component pieces from the first refractory component pieces.
Claims11
A method of reclaiming refractory material from a working lining of a refractory vessel, comprising:
- assembling a first refractory component of the lining with a first non-magnetic refractory product;
- assembling a second refractory component of the lining with a second refractory product different from the first refractory product, wherein the second refractory product includes magnetic material dispersed therein;
- upon the lining reaching a service life, demolishing the lining to produce a mixture of first refractory component pieces and second refractory component pieces;
- and
- performing magnetic separation on the mixture to separate the second refractory component pieces from the first refractory component pieces.
