MOISTURE-RESISTANT FUEL BRICK AND METHOD OF PRODUCTION THEREOF Russian patent published in 2009 - IPC C10L5/14 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to solid shaped fuel technology and can be used in metallurgy, municipal economy and various industries. Fuel bricks based on coke, anthracite breeze and binder molasses solution additionally contains termoanthracite in ratio, wt %: 20-25 anthracite, 25-30 thermoanthracite, 5-16 molasses solution, and the rest - coke breeze. Components are dose out, mixed, preformed and dried. Preforming includes two-sided brick compression under pressure 35-50 MPa within 5-8 seconds. It is possible to dry air brick in dryer at temperature 380°C within 90 minutes.

EFFECT: higher moisture resistance and heat stability of brick produced by simplified method; production of bricks to be used in cupola furnace for iron smelting.
