TUYERE FOR ENERGY SAVING IN BLAST FURNACE

摘要

PURPOSE: A blowhole for an energy-saving type furnace, capable of the heat loss reduction of a furnace, is provided to reduce energy cost and carbon tax and to improve service life of a blowhole by improving the erosion resistance about a high temperature of molten substance. CONSTITUTION: A blowhole for an energy-saving type furnace comprises a blower line, a cooling water line(4) and a refractory material(1). The blower line supplies a high temperature of air to the inside of a furnace. The cooling water line is formed in the outside of the blower line. The refractory material is formed on the side surface unit and tip-end part of a blowhole.
