Problem description:

Temperature  field inside the crucible stove

Geometry is as follows:

     Stove height = 740mm;
     Stove width  = 800mm;

     Crucible height = 680mm;
     Crucible up width = 640mm;
     Crucible down width = 400mm;

     Cover of stove height = 60mm;

Parameters:

     Fire-clay heat transfer coefficient    = 0.837+0.582t W/(mK);
     Mineral wool heat transfer coefficient = 0.0583 W/(mK);
     Glass tape heat transfer coefficient   = 0.058 W/(mK);

     Inner stove surface:

          temperature of air = 700C.

     Outer stove surface:

          temperature of outer material = 50C;
          temperature of contacting air = 20C.
