Dinas parts with a new form of iron-containing mineralizer

Conclusions

The properties of a new form of iron addition, steel production wastes, for the preparation of the lime-iron slip in the production of dinas parts were studied. It was established that the wastes have a significantly higher FeO content than pyrite cinders. The rheological properties of the milk of lime base slips with pyrite cinders and with wastes are practically the same with a consumption of wastes 1.5 times less than of pyrite cinders. Better pressability of the mixtures with the use of wastes was established.

The quality of production parts produced with the use in the lime-iron slip of steel production wastes completely meets the requirements of the standards for dinas production. The use of dehydrated slurries of steel production wastes (without preliminary drying of them to avoid conversion of FeO to Fe₂O₃) is recommended in the production of dinas parts of different types.
