Magnesia-Carbon Based Refractories |
Example 2 |
Example 3 |
| Tata Steel IJmuiden has two refractory plants at its disposal, which produce approximately 20,000 tonnes of refractory materials annually: |
- HSF: Hoogovens Stop en Stampmassa Fabriek.
This plant produces tap hole mixes and ramming materials for the troughs and slag runners.
- REP: Refractory Plant.
This plant produces bricks for the torpedo cars, hot metal ladles, converters and steel ladles. For some applications ramming masses are produced.

| Raw materials |
| The plants have the availability of several refractory grains and additives: |
| |
- Bauxite
- Carbon
- Silicon carbide
- Silicon nitride
- Kyanite
- Clay
- Magnesite sinter and melt
- Metallic aluminium
- Graphite
- Others

| As a binder agent the plants have the availability of: |
- Tar
- Resin
- Phosphate
- Clay
- Others

| Recipe development |
| CRC plays an active role in the development of the recipe for the different applications. After having set up the demands of the product in cooperation with the customers, CRC has the expertise to translate the demands of the material in use to a tailor-made recipe. In order to obtain the optimum density, the grain size distribution is an important item e.g.: Fühler grain size distribution. A computer model for mixing several raw materials with their own grain size distribution to fit the desired sieve analyses of the end product is available. After composing the recipe on a laboratory scale, standard and simulation tests are performed to obtain know-how in the behaviour of the recipe. The recipe is applied in the refractory plants and the final product is tested in practice. Depending on the results, a new optimization of the end product may be necessary. At the end, a tailor-made recipe is developed for a material, which has the best value in use. |
