Materials
The chosen belt specification was one typically used in the sintering process of the powder metal industry. Fig. 1 shows a section of a typical balanced woven wire mesh furnace belt prior to being put into service. The belt is constructed by forming wire into elongated coiled spirals and then tying the spirals together with cross rods (Figs. 2 and 3). This studv used a furnace belt commonly referred to as a B-36-10-8-10. It is a balance weave, which means the belt is assembled with alternating left and right hand spirals. The belt has 36 loops per foot of width and 10 loops (or cross rods) per foot of length. The connecting rods and spiral loops were made from 8- and 10-gauge 314 stainless steel alloy wire, respectively. These belts are typically two to four feet wide and the lengths vary.

The analyses used the material properties of 310 stainless steel at 2000o F instead of 314 stainless steel alloy due to the lack of material properties for 314 stainless steel alloy at 2000o F. The Nickel Development Institute felt that the mechanical properties of 310 stainless steel would be similar to 314 stainless steel alloy at elevated temperatures. A Young's Modulus of 8.40 x 106 psi and a Poisson's Ratio of 0.27,[2] along with area properties listed in Table I, were used for the linear analyses.
