substitute heat treatment to preserve food products, as it inactivates vegetative microorganisms, spores, and enzymes as well, thus increases shelf-life, in case of fruits and vegetables up to 4–6 weeks with refrigeration storage ( Matser and Timmermans, 2016

Abstract

A welded steel protective cover used for the heat treatment of steel sheet coils is investigated. The protective cover is made of austenitic stainless steel and consists of three main segments, welded together, which have 1400 mm height each. The plate thicknesses at the lower, middle and upper segments are different. The investigation aimed to improve the lifetime and the number of heat cycles of the protective cover by changing the geometry, the effect of the thicknesses and the material. Damaged covers have been evaluated, made calculations of stress and deformations, and carried out a series of finite element simulations. Both horizontal and vertical corrugated sheets were simulated and compared. The non-corrugated plates were also investigated, but their performance was behind the corrugated ones. The original geometry and that of the horizontal corrugated plate are identical from the stress level point of view. The vertical position of the corrugated plate provided a better result than the horizontal one. The calculated and simulated results for the original geometry are close to the measured damage.

castings are normally (but not totally) limited to non-structural components that do not require such a heat treatment or welding. Porosity causes more rejected castings than any other factor. In cold-chamber die casting of aluminum alloys, air and
