THE PRACTICE OF USING TECHNICAL FABRICS IN THE PRODUCTION OF HEAT-RESISTANT SLEEVES
The article has developed and mastered promising technologies for the production of heat-resistant metallurgical hoses, which include the use of synthetic materials for the power frame and fire-resistant - cover fibrous materials. Experimental studies have been carried out to reduce the material consumption of the production of sleeves, due to changes in manufacturing technology at the stage of cutting the strips of the power frame and assembling the sleeves. A sleeve manufacturing technology is described, which provides for the introduction of a wire spiral into the sleeve design to protect the sleeves from loss of transverse stability and reduce the bending radius. Technical cord materials for the manufacture of a power frame for sleeves of various types in production are considered. The technology of protecting the outer surface has been mastered, providing for the creation of bumpers of various design schemes. In order to increase the temperature resistance of the operation of metallurgical heat-resistant sleeves, a technology has been created for the manufacture of sleeves based on non-flammable and fire-resistant fabric materials covering the sleeves on the outer surface. The operation of the hoses showed the correctness of the developed technologies and the choice of appropriate materials. Research work on the development of new fire-resistant materials for heat-resistant hoses has been carried out. The prospects of using innovative technology for manufacturing heat-resistant metallurgical hoses are noted.
