METHOD OF ELECTROSLAG MELTING OF FERROTITANIUM |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: invention refers to special electrometallurgy and is designed for production of ferrotitanium of high quality out of titanium and steel chips. Melting of titanium and steel chips is performed in a slag bath in a water-cooled crystalliser by means of supply of electric current into slag through a non-consumable graphite electrode. Chips are loaded into the crystalliser by portions at amount of 20-50% from the total weight of chips. After melting of each portion of chips density of current is lowered at the electrode at 50-70% relative to density of current of melting and holding is carried out at lowered current density during 1-5 minutes. Further next portion of chips is melted. ^ EFFECT: producing ferrotitanium with high chemical uniformity along height of built-up ingot. ^ 2 cl, 1 tbl |
