Experience with ferrosilicoaluminum alloy during deoxidation of steel

The article describes the process of deoxidation quiet and low-alloyed steel alloy ferrosilicoaluminum complex in comparison the existing, and with steel deoxidation technology with conventional alloys - ferrosilicon and secondary aluminum. A comparative analysis of quality steel, non-metallic inclusions metallographic studies and studies of the mechanical properties of the resulting steel was done. On a large array of experimental steel proved cost-effectiveness and feasibility of ferrosilicoaluminum during deoxidation quiet and low-alloyed steel

Experimental melting of high-silicon ferromanganese with the use of ferromanganesian ore and manganese slag

This work presents the results of smelting ferromanganese from high-silica iron-manganese ores with 36 % manganese content by the flux method. The Shubarkol deposit coal and metallurgical coke as reducing agents were used. The fluxing material was solid slag from the smelting of medium-carbon ferromanganese. The technological modes of the smelting process are established. The optimal composition of the charge was determined. As a result of the theoretical and experimental studies, the tasks have been solved completely - the smelting technology of high-silicon ferromanganese was developed and tested using a substandard raw materials, such as iron-manganese ores and flux

EYE LESIONS IN SYPHILIS

The paper is focused on diagnosing eye structure lesions in patients with syphilis. Two clinical cases are described: a case of syphilitic uveitis in early syphilis and optic nerve atrophy in late syphilis. The main purpose is to increase the awareness of ophthalmologists about specific eye diseases in syphilis and the need for early detection of such pathologies.
