METHOD OF PLOUGHSHARE RECOVERY

摘要

FIELD: process engineering. ^ SUBSTANCE: invention may be used for recovery of ploughshare parts. Metal stock is formed on ploughshare rear, at ploughshare tip and along its length, by manual building-up welding by low-carbon electrode, or automated electric-arc welding. Built-up metal is expected to allow recovery of rated sizes of ploughshare. Hot straining is carried out using jig gauging ploughshare tip and blade. Surface hardening is carried out. ^ EFFECT: recovery of ploughshare geometrical parametres. ^ 1 dwg
