Abstract
Experimental study of strength of glued connections where repair mixtures Diagum FL, Diagum Р and Diaflex are used is shown. Suggestions of each repair mixture use are given. Obtained results provide developing of durable and economical technical solutions: shear shock absorbers, elastic couplings, elastic shafts with high energy intensity which in some cases allow to avoid failures of metallurgical equipment under dynamic loading. In addition, use of repair mixtures with elastomers helps to make durable coatings of steel surfaces.
Highlights
Elastomers are increasingly used in metallurgical engineering. These are different elastic elements made from rubber and polyurethane installed in steel assemblies, namely, buffers, shock absorbers, elastic shafts and couplings, protectors for protection of metallurgical equipment against accidental breakdowns, etc. [1,2,3,4,5]
For all above mentioned devices and details [6,7,8] elastomer layer must be firmly connected to metal surface
Hot involves connecting elastomer and metal by means of vulcanization that is laborious: firstly, metal surfaces that will be connected to elastomers are coated with layer of brass or ebonite and these metal surfaces are vulcanized with rubber
Summary
Elastomers are increasingly used in metallurgical engineering. These are different elastic elements made from rubber and polyurethane installed in steel assemblies, namely, buffers, shock absorbers, elastic shafts and couplings, protectors for protection of metallurgical equipment against accidental breakdowns, etc. [1,2,3,4,5].Another group of devices and details have elastomers as coatings of steel surfaces that prevent premature abrasive wear of covered surfaces, these are sieves of screens, outer surfaces of rollers for removing liquid from surfaces of metal strip, inner surface of mills drum, outer surfaces of rollers for transporting cold rolled products, etc.For all above mentioned devices and details [6,7,8] elastomer layer must be firmly connected to metal surface. For all above mentioned devices and details [6,7,8] elastomer layer must be firmly connected to metal surface. Rigidity and durability of combined detail or device depend on strength of connection between elastomer and metal [9, 10].
