LANCE ASSEMBLY FOR ELECTRIC FURNANCE AND METHOD FOR FEEDING OF MATERIALS USING THE SAME

摘要

PURPOSE: A lance assembly for an electrical furnace and a material input method using the same are provided to simplify the whole facility structure and enhance workability since a plurality of materials can be mixed and put in ingot steel through one path in manufacturing steel. CONSTITUTION: A lance assembly(200) for an electrical furnace comprises a lance tip(210), and a mixing unit(220). The lance tip is formed to be able to be arranged toward the inside of the electrical furnace. The mixing unit comprises first and second parts. The mixing unit comprises a housing(221), which has a space capable of holding materials. The first part is formed so that a plurality of materials are put in. The first part comprises a plurality of supply lines(222) and a plurality of inlets. The materials move through the supply lines. The inlets are formed where the supply lines meet the housing.
