The welding of bandages
The welding of bandages into the case solves the problem of reducing to a minimum of ring deformations in supporting sections, where, with a “floating” bandage planting system, they were maximum, and thereby significantly increases the resistance of the lining. This will be especially important for large diameter furnaces under construction.
When welding the bandage into the furnace, an anxious shell is excluded, requiring significant labor costs for rollering, welding and machining. The stove -length setting of a number of bands of the bands -Diafragm allows you to reduce the thickness of the case in the flight, since the strength of the case with the ratio of the diameter to the span even with the thickness of the case, which is much smaller compared to the existing ones, it is easy to ensure, and the most important characteristics of the case – ring rigidity – will be ensured by welding of hard rings (bandages) into the furnace body.

Applying a new support system and a rigid landing of the bandage, the designer can accurately calculate the case. Changing the conditions of support and boundary conditions on the supports simultaneously improves the work of structures and allows you to design reliably.
The furnace body should be calculated as an underlying multi -foop cylindrical shell by semi -solid theory, which makes it possible to determine longitudinal and ring stresses, radial movements and even a change in curvature around the perimeter.
When calculating the furnace body as an underdeveloped multi -span beam of tubular cross -sectional methods of resistance of materials, the information of the transverse section of the body is assumed. This is a condition for the thin -walled shell, which is the case of the furnace, is unacceptable, since the contour of the shell undergoes significant radial deformations.
