OPERATION OF VERTICAL TYPE SCRAP MELTING FURNACE

Title:

OPERATION OF VERTICAL TYPE SCRAP MELTING FURNACE

Document Type and Number:

Japanese Patent JPH09256019

Kind Code:

A

Abstract:

To drastically improve the energy efficiency, i.e., to remarkably reduce the requirement unit of coke by effectively reducing solution loss at the time of melting operation of scrap.

In the operation of a vertical type scrap melting furnace 1, a carbonaceous material 3 whose surface is coated with a material which is difficult to be oxidized with high temp. CO2 and H2O and, on the other hand, material covered with such a substance which is lost by combustion, vaporizing, melting, etc., is used at the lower part of the vertical furnace 1. The charging of at least the scrap 2 in the charging raw materials is continuously executed from the furnace top part to the furnace lower part of the vertical furnace 1.
