Abstract
Alloy carrier for charging cupola furnaces, the carriers having the form of bodies molded with cement, the alloys being manganese as ferromanganese and silicon in the following composition 8-40% Mn 9-22% C 2-9% Fe 18-45% Si 15-30% Portland Cement 4-8% H.sub.2 O chemically bound 2-7% residue components (all percentages by weight) wherein the manganese carrier is ferromanganese carbure and the silicon carrier is silicon carbide.
Claims1
An alloy carrier for charging cupola furnaces, the carrier having the form of bodies molded with cement, the alloys being manganese in the form of ferromanganese and silicon, in the following composition:
- 8-40% by weight, Mn
- 9-22% by weight, C
- 2-9% by weight, Fe
- 18-45% by weight, Si
- 15-30% by weight, Portland Cement
- 4-8% H.sub.2 O, chemically bound
- 2-7% impurities
- characterized by the employment of ferromanganese carbure having a carbon content of 6% to 8% as the manganese carrier and silicon carbide as the silicon carrier.
