FIELD: textile fabrics; paper.
SUBSTANCE: invention relates to recovery method of diametric dimension of drier of paper-making equipment. After turning cut of cylinder it is implemented thermal processing of surface at temperature 100°C in passage area of electroarc burner. Then one-pass by material M470 it is applied the first adhesion layer of coating of solidity 360-420 HB of thickness 0.1 mm. It is applied the second filling layer by material ST-0002 of solidity 360-420 HB, thickness of which corresponds specified value of increase of diametrical dimension. It is applied the third coating cover of thickness 0.5 mm by material ST-0028 of solidity 250-270 HB, subject to allowance 1-2 mm for complete machining. Application is impregnated by compound "Hartz" in cooled condition, grind and polished the surface by flexible tool with providing of roughness Ra<0.63 micrometre, it is washed workpiece surface by mineral oil. After what it is run in surface of cylinder by edge scraping tool with angle of wedge slope 25°-30° and linear pressure 200-300 N/m.
EFFECT: it can be used in mechanical engineering at repair of driers without removal of it from the operation position.
