8.The right angle (RA) shown here, has all the electrical characteristics of the RR.
9.DB has a negative resistance temperature characteristic from room temperature to approximately 1200?F (650?C).
11.If the element is not able to dissipate heat energy equally in all directions, it may cause local overheating and possible failure.
12.Recommended terminal hole diameters for various refractory walls and sizes are shown in Table C.
13.Recommended terminal hole diameters for various refractory walls or plugs and Element sizes are shown in Table C, page 5.
14.The amount of energy that a is capable of converting from electrical to heat energy depends on the ambient furnace temperature and atmosphere in which it is operating.
15.Twelve elements connected four in series per phase on 240 volts would make a balanced three phase 240 volt network.

20.The temperature distribution on the high temperature side of an electric tunnel furnace is analysed and simulated on the basis of the principle of thermal radiation by the way of THB(Thermal Heat Balance).The heated silicon carbon sticks are decomposed into innumerable tiny heating faces,which exchange the heat with the heated materials.A numerical model based on the radiation intensity law is constructed to calculate the energy absorbed by the heated materials and simulated by a computer.The results showed that the even distribution of temperature can be obtained by optimizing the arrangement of the silicon carbon sticks according to the calculation results to make the structure design more reasonable.These calculation results have been used in the practical designs and the expected objectives achieved.
