The slug component conditioner for reactor internal Hari refractory conservation and the powder granular

摘要

PROBLEM TO BE SOLVED: To provide a slag-component adjusting agent which effectively restrains melting-damage of a lining refractory by being rapidly melted when this agent is charged into a furnace, and prevents gas from being suddenly blown-out from the furnace opening hole when this agent is charged.;SOLUTION: The slag-component adjusting agent is a molded product, wherein particulate raw materials consisting essentially of Mg-containing raw material, are molded and solidified, and the molded product contains a gas-generating material (A), wherein the gas-generating temperature is ≤400°C, and a gas-generating material (B), wherein the gas-generating temperature is ≥600°C. Since the gas-generating material generating the gas at the temperature in the furnace is contained, high solubility is attained, and when this agent is charged into the furnace, since time difference is caused between the gas generation from the gas-generating material (A) and the gas-generation from the gas-generating material (B), the generation of the gas is made calm to prevent the gas from being suddenly blown-out from the furnace opening hole.;COPYRIGHT: (C)2010,JPO&INPIT
