Examination of research into pole alternatives indicates that, without exception, studies have found that total energy requirements associated with wood materials are considerably lower than those of commonly substituted materials. The substitution of high-energy-intensive materials for low-energy-using wood materials would contribute substantially to an overall increase in carbon
Alcohols and other low molecular weight oxygenates are known to be potentially valuable gasoline substitutes. While these are generally of interest in relation to the long-term need to secure future motor fuel supplies, there is a more urgent need for substitutes which will improve the octane rating of unleaded fuels. For environmental reasons, oxygenates including alcohols may be preferred to ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
