FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Crystalliser cartridge comprises walls to form its inner chamber. Crystalliser cartridge wall have outlet section formed by chambers inclined to each other at 5°…7°. Chamfer length makes 0.15-0.20 of cartridge length. Conical grooves are made on outlet section between said walls over the chamfer length. Groove radius at outlet makes 0.2-0.3 of wall thickness. Crystalliser cartridge is made from beryllium bronze.
EFFECT: higher quality of billet and reduced wear of walls.
