The expediency of carrying out the process of dephosphorization of the alloy in one stage using a briquetted mixture, which includes iron scale, lime, bauxite and sodium orthosilicate in their following ratio, wt.%: Iron scale - 52.0… 57.4; lime - 6.2… 8.6; bauxite - 4.5… 6.2; sodium orthosilicate - 30.5… 30.4. The achieved degree of dephosphorization of the accompanying manganese alloy is about 70%, the manganese content in the alloy - 64.6%. The implementation of dephosphorization according to the developed method allowed to increase the rate of throughput of manganese from the raw material. Exclusion from the composition of materials for dephosphorization of fluoride compounds increases the environmental friendliness of the refining process. In the real conditions of production in the process of depho-?phorization of the associated alloy may use different processing schemes and conditions of its implementation. In the formation of a concomitant alloy with a temperature of ~ 1300oC in the production of low-phosphorus slag, in order to minimize the cost of dephosphorization of the alloy using existing shop equipment, the refining process can be implemented according to the following scheme and purging the bath with argon, the dephosphorization process scheme may include the following operations: adding 100% pre-briquetted SHUS, to the bottom of the bucket, trans-?orting the bucket to the installation of the oven-bucket, where the optimum temperature will be maintained during refining. This will increase the refining time and, consequently, greater completeness of the refining process .: Key words: highly phosphorous concomitant alloy, slag-forming mixture, ladle furnace, completeness of depho-?phorization.
