Use the given data to determine the suitability of the electro-graphite steel support furnace roll, the furnace operates at a maximum temperature of 1250 degree celcius, the roll experiences heat by radiation and conduction when the strip-line of 28 ton passes on it continously Find Heat transferred to the roll, the roll diameter is 160 mm and length of roll is 3530 mm. And determine if with the given data and material (electro-graphite roll) the roll will withstand a normal working temperature ranging from 1050 to 1200 degree celcuis. Given Data: Density 1740 kg/m Hardness 40 shore C2 Flexural breaking limit - 19 MPa Compression - 36 MPa Co-efficient of expansion 2.4 x 10-6/K Thermal Conductivity - 190 W/m.k Resistivity - 900 Q. cm Max grain size 0.8 mm Volume porosity 15% Ash content 0. 10%
