Abstract
The invention concerns a batch for the production of a refractory magnesia-carbon product or a refractory alumina-magnesia-carbon product, a process for the production of a refractory magnesia-carbon product or a refractory alumina-magnesia-carbon product, a refractory magnesia-carbon product or a refractory alumina-magnesia-carbon product as well as the use of a magnesia-carbon product or a refractory alumina-magnesia-carbon product.
Claims8
A batch for the production of a refractory carbon-bonded product, comprising the following components in the following proportions by weight, respectively with respect to the total weight of the product:
- 70% to 97% by weight of a base component;
- 1.0% to 2.3% by weight of a binder component in the form of at least one resol;
- 1.5 to 3% by weight of a binder component in the form of at least one pitch;
- 1.0% to 28% by weight of a carbon component in the form of at least one of the following carbon sources:
- graphite or carbon black.
A process for the production of a refractory carbon-bonded product, comprising the following steps:
- providing a batch, the batch comprising the following components in the following proportions by weight, respectively with respect to the total weight of the product:
- 70% to 97% by weight of a base component;
- 1.0% to 2.3% by weight of a binder component in the form of at least one resol;
- 1.5 to 3% by weight of a binder component in the form of at least one pitch;
- 1.0% to 28% by weight of a carbon component in the form of at least one of the following carbon sources:
- graphite or carbon black;
- shaping the batch into a shaped article;
- tempering the shaped article;
- and
- applying heat to the tempered shaped article in a manner such that the carbon of the binder components as well as of the carbon component forms a carbon bond in order to produce a refractory carbon-bonded product.
