INSTALLATION TO EXAMINE PHYSICAL AND MECHANICAL PROPERTIES OF COAL PRODUCTS Russian patent published in 2002 - IPC

FIELD: determination of physical and mechanical properties of coal products, test of lining materials of aluminum electrolyzers under conditions of electrolysis. SUBSTANCE: installation to examine physical and mechanical properties of coal products comprises measurement system to investigate coefficient of thermal linear expansion, thermal expansion and shrinkage, measurement system to determine expansion of examined material exposed to effect of sodium, measurement system to determine modulus of elasticity and compression strength and common processing unit. Measurement system to investigate coefficient of thermal linear expansion, thermal expansion and shrinkage has shaft electric furnace with heat converter placed inside. Displacement transducer contacting rod of sample holder is installed in cantilever above furnace on heat insulator. Measurement system to determine expansion of examined material exposed to effect of sodium has shaft electric furnace which center zone houses heat converter and sample holder fitted with linear displacement transducer and loading unit incorporating eccentric. Measurement system to determine modules of elasticity and compression strength has steel sleeve with lid in which linear displacement transducers are installed. EFFECT: increased timeliness, accuracy and complexity of measurement of physical and mechanical properties of coal products. 2 cl, 6 dwg
