FORMATION OF STRUCTURE OF HOOKS OF LOADING LIFTS IN CONDITIONS OF SHS

Abstract

The article deals with the formation of the structure of hoists for lifting cranes in order to prevent the development of cracks by forming the structure of steel 20 by treatment in the conditions of self-propagating high-temperature synthesis (SHS) to obtain fine-grained ferrite-perlite structure. The conducted researches allow to form a rational structure of steel to exclude the development of cracks in dangerous sections of lifting hooks of hoisting and transport mechanisms working in the shops of metallurgical production. The method of structure control after SHS is developed taking into account the influence of different diameters of hooks.
