METHOD OF MAKING STEEL BODIES FOR CARBON DIOXIDE FIRE EXTINGUISHERS

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to metal forming and can be used in making steel cases for carbon-dioxide fire extinguishers. Ends of tubular billet from electrically welded pipe, made by welding with high-frequency currents from rolled metal with yield point exceeding 38 kgf/mm², heating and forming a bottom and a neck.;EFFECT: increased reliability of housing due to reduced eccentricity and reduced probability of cracks appearance.;1 cl
