DEVELOPMENT OF RECOMMENDATIONS IN INCREASE OF QUALITATIVE INDICES OF CASTINGS «SLEEVE»

Recommendations on increase of qualitative indicators of castings «Sleeve» are given. It is shown that for modifying of melt it is offered to use just modifier MK95 in quantity of 4–6 kg per 1 ton of liquid metal

DESULFURIZATION OF STEEL IN CONDITIONS OF GUP «LPZ». DEVELOPMENT OF RECOMMENDA¬TIONS ON INCREASE OF ITS EFFICIENCY

The analysis of sulphur removal of steels in the stove-busket is carried out. Besides, statistical processing of quantities of flux metals and ferroalloys, given to the stove-busket at various stages of melting which has confirmed the assumption of economy of ferroalloys due to additional processing deoxidizing mixtures, is carried out

The mechanical characteristics of the high-strength cast irons, melted in different melting units

There is shown the comparison of qualitative figures of ChShG, received by modification in the mode, but melted in different unit

DEVELOPMENT OF NEW SAFE FLUX FOR ALUMINIUM AND ITS ALLOYS

It is shown that application of the new combined flux metal will allow to improve ecological conditions in casthouse, with use of waste of the used agglutinant sand will give the possibility to carry out the reclaiming of the soils

THERMODYNAMIC MODELING OF CHEMICAL REACTIONS OF STRONTIUM CARBONATE IN ALUMINIUM MELT

The received calculation data confirm the assumption on possibility of carrying out of silumins modifying processing with strontium carbonate in production conditions

ANALYSIS OF THE HIGH-TEST CAST IRON QUALITY WITH APPLICATION OF METHODS OF MATHEMATICAL STATISTIC

is determined that application of bowl with lid for spheroidizing processing of melt allows to receive high-test cast iron without pyroeffect and smoke emission
