Abstract

The invention discloses a blast furnace granulated slag light heat preservation refractory casting material and the manufacture method. It is made up from 5-65 portions of blast furnace granulated slag, stabilizer 0.1-1 portion, aggregate 0-60 portions, refractory powder 15-30 portions, binding agent 5-20 portions, and additive 0.1-1 portion. The process including the following steps: taking drying of the blast furnace granulated slag, mixing with refractory powder, binding agent, stabilizer and additive, whisking with water, shocking, molding, and de-mouding. The invention has great economic, environment protection and social benefits.

Description

technical field [0001] The invention relates to a steel blast furnace, in particular to a blast furnace water slag lightweight heat-retaining refractory castable and a preparation method thereof. Background technique [0002] At present, our country has proposed the concept of green manufacturing in the metallurgical industry. In order to achieve this goal, environmental protection should be incorporated into the thinking of system engineering, and the environmental problems existing in the relatively independent unit of metallurgical enterprises should be considered and dealt with in a unified way, so as to truly achieve the goal of metallurgical industry. Ecological production and zero discharge of pollutants. [0003] Since 1996, my country's steel output has ranked first in the world for 9 consecutive years. In 2004, it was 270 million tons, and in 2005 it could reach 330 million tons. It has become a veritable steel power. However, as an industry with high consumption ...
