Technical Field
The utility model relates to the technical field of furnace body cooling equipment of an iron-making blast furnace, in particular to a wear-resistant copper cooling wall.
Background
Because the working environment of the copper cooling wall is very severe, the refractory materials embedded in the groove have a protective effect on the copper cooling wall during the furnace opening period, but the refractory materials and the furnace lining disappear after several months of operation, and if the exposed copper cooling wall cannot quickly form a layer of stable slag crust, the heat load is increased. Under the conditions of high-temperature gas flow scouring and chemical substance erosion in the furnace, on one hand, the repeated thermal shock causes huge stress to be generated on the copper cooling wall, so that the cooling wall is cracked and damaged; on the other hand, the exposed copper cooling wall is easy to cause heat loss increase; when the slag crust protective layer is in effect, the normal working temperature of the body of the copper cooling wall can be guaranteed to be lower than 60 ℃, and after the slag crust protective layer falls off, the instantaneous temperature of the body of the copper cooling wall can reach or exceed 150 ℃ until the slag crust protective layer is formed again. It can be seen that the slag crust protective layer frequently falls off, which causes severe fluctuation of the blast furnace condition, the copper cooling wall is continuously washed by hot air flow and material flow, and even causes abnormal damage to the copper cooling wall, thereby affecting the service life of the blast furnace.
In addition, the thermal deformation tendency and the deformation amplitude of the cast copper cooling wall with the exposed hot surface in the blast furnace are related to the temperature distribution of the wall body, and the cast copper cooling wall is easy to generate bow-shaped deformation.
Therefore, a wear-resistant copper cooling wall which is wear-resistant and easy to stick slag is needed to overcome the problems.
