Abstract
Description
1. Technical field
[0001] The invention relates to a thermal shock-resistant refractory brick formed by combining mud and used in a blast stove for smelting iron and steel and a production method thereof. 2. Background technology
[0002] The development of the world economy provides a broad market for steel production. At the same time, higher requirements have been put forward for steel production. Especially with the large-scale blast furnace and the development of hot blast stove longevity technology, the quality of hot blast furnace lining materials is becoming more and more important. Due to the harsh working conditions of hot blast stove burner bricks, pipe bricks, hot blast outlets and other parts, frequent alternation of cold and hot (heat Shock phenomenon), it is more destructive to the refractory materials in these parts, and the life of the hot blast furnace is closely related to it. Anti-flaking high-alumina bricks are generally formed by combining water or li...
