Abstract
A method of separating a mixture of used refractory components of different chemistry types obtained from a demolished refractory includes hydrating the mixture of refractory components to destructively hydrate at least some components of the mixture of refractory components, and separating, based on size, the at least some components from other components of the mixture of refractory components.
Claims23
A method of recycling refractory components, comprising:
- constructing a liner for a metallurgical vessel, the liner formed from at least two different carbon-bonded refractory components, wherein the at least two different carbon-bonded refractory components are selected based on hydration characteristics of the carbon-bonded refractory components;
- demolishing the liner to produce a mixture of carbon-bonded refractory components of different chemistry types;
- destructively hydrating the mixture of carbon-bonded refractory components to produce components of reduced size;
- and
- separating the components of reduced size into at least two groups based on the relative size of the components.
A method of separating a mixture of used refractory components of different chemistry types, the used refractory components obtained from a demolished refractory liner constructed from at least two different carbon-bonded refractory components, wherein the at least two different carbon-bonded refractory components are selected based on hydration characteristics of the carbon-bonded refractory components, the method comprising:
- hydrating the mixture of refractory components to destructively hydrate at least some components of the mixture of refractory components;
- and
- separating, based on size, the at least some components from other components of the mixture of refractory components.
