PROTECTIVE TECHNICAL COATING FOR STEEL AND ALLOYS

摘要

FIELD: chemistry. ^ SUBSTANCE: present invention pertains to corrosion protective coatings during process heating when making high-quality components and intermediate products from steel and alloys. The coating contains the following, in wt %: Al2O3 - 17-33; CaO - 0.5-7,8; MgO - 0.5-5; 2CaOSiO2 - 0.5-1; 3CaOAl2O3 - 0.5-1; 2MgOAl2O35SiO2 - 5-10; CaO6Al2O3 - 5-10; SiO2 - constitutes the rest. ^ EFFECT: increased temperature stability and thermal insulation properties of the protective coatings for steel and alloys when heated to 1200C. ^ 4 ex, 2 tbl
