Claims13
A refractory ceramic batch for the production of an unformed refractory ceramic product which comprises the following raw materials:
- 1. 1 one or a plurality of magnesia-based raw materials low in iron with a fraction of 66 to 94% by mass;
- 1. 2 one or a plurality of calcium carbonate-based raw materials with a fraction of 5 to 30% by mass;
- and
- 1. 3 iron powder with a fraction of 1 to 6% by mass.
A method comprising:
- lining metallurgical melting vessels with unformed refractory ceramic product, wherein the unformed refractory ceramic product comprises:
- 1. 1 one or a plurality of magnesia-based raw materials low in iron with a fraction of 66 to 94% by mass;
- 1. 2 one or a plurality of calcium carbonate-based raw materials with a fraction of 5 to 30% by mass;
- and
- 1. 3 iron powder with a fraction of 1 to 6% by mass.
