A kind of new turblent flow in annular square channel with two cooled wall was designed on basic thermophoresis principle.

Failure analysis and prevention for the damaged cooling wall of No.4 BF at Guangsteel;

Leak detecting for soft water closed circulation system and solution on making water of cooling wall are also introduced.

6 section cooling wall tube root of blast furnace bosh were analyzed from three aspect cooling water of the blast furnace,body of the cooling wall and operation of the blast furnace,and according measures were decided to reduce and eliminate the breakage.

Model for inner proffie control of furnace wall lined with copper cooling stave based on the inverse problems in heat transmission;

Study on the hot characteristics of hot and cold sides of the copper cooling stave with circular channels;

Adopting copper cooling stave to prolong BF campaign;

The calculation models of the heat transfer coefficient between the blast furnace gas flow and the heat surface of stave are established based on the substitution method of boundary condition.

4 blast furnace was considerably deteriorated, with its shaft's stave seriously damaged, the temperature of the cooling water in the furnace hearth's stave abnormally increased, the furnace bottom's temperature reaching an alarming level, and the furnace shell cracked and deformed in a number of locations.

The development and application of the inner profile management model in Angang's BF lined with the copper stave;

Realizing the self-protect ability of a blast furnace cooling system with copper stave;

Manufacture technology and progress of cooling staves for blast furnace;

Convective heat transfer boundary equivalent replacement and model simplification of cooling stave of blast furnace hearth;
