Abstract

External quality control of the chemical-analytical departments of the central factory laboratories was carried out: PJSC Krasnoarmeysky Dinas Factory, PJSC Chasovoyarsk Refractory Plant, PJSC Velikoanadol Refinery Plant. During the chemical analysis of samples of refractories of the listed enterprises, the analysis methods, equipment and materials described in DSTU 3305(3, 4, 5)—96 (GOST 2642.(3, 4, 5)—97) — gravimetric (SiO2), complexometric (Al2O3), photometric (Fe2O3). As a result of the work carried out, conclusions were drawn up in which the quality of the work of the chemical analytical units of the central factory laboratories of the PJSC “Krasnoarmeysky Dinas Factory”, PJSC “Chasovoyarsk Refractory Plant”, and PJSC “VELIKOANADOL REFRACTORY PLANT” was considered satisfactory.
