The operation of large-sized equipment at high temperatures leads to the appearance of residual deformations. This reduces the service life of the products and safety of their use. To improve the service life of such products, reinforcing ribs fixed by welding can be used. The technology of strengthening of a large-sized product is shown by the example of a cinder car slag-pot, the improvement of which allows reducing the deformation of the case by 4-5 times.

reinforcing ribs, thermal deformations, welding, metallurgical equipment, high temperatures, increase of service life.
