  • Publication number: 20180304330
    Abstract: Blank of corrosion-resistant steel is coated with coating of water glass with thickness of 20 to 150 ?m, cured at 15 to 60° C., and heated in an induction furnace to the temperature of 1180° C. to 1260° C. The heated up blank is without cooling by water descaling transferred into an extrusion press and extruded here, while the coating is broken to pieces and largely removed. Drawing in a horizontal drawing press and necking are performed. After forming to the final shape of the cylinder, leftovers of coating are removed by pressure blasting. A corrosion-resistant thin-walled seamless high-pressure cylinder with volume of 5 to 260 litres is manufactured.
