Background
The copper cooling plate is widely applied to high-temperature smelting furnace bodies such as blast furnaces, electric arc furnaces and submerged arc furnaces, and long-time normal operation of the smelting furnace is guaranteed by taking away heat of refractory materials of the furnace bodies. For example, the working temperature of the blast furnace body is very high, and the local temperature can reach more than 1600 ℃. In the conventional blast furnace, copper cooling walls are adopted, and copper cooling plates are also adopted in part. The copper cooling plates take away the redundant heat in a cooling water heat exchange mode, and a slag crust is formed in the furnace in time, so that the service life of the blast furnace is prolonged. But the hot surface of the copper cooling plate cannot be washed by the charging materials and molten iron in the working process. The existing copper cooling plate (as shown in figure 1) is mainly cast, generally contains more than or equal to 99.5% of copper, is allowed to work at 150 ℃, has the density of 8.4g/cm3, the tensile strength of 170MPa, the hardness of 35-45HB and the heat exchange coefficient of 340W/(m.K), is easy to generate defects such as air holes, looseness, cracks and the like, ensures that the effective thickness of the hot surface of the copper cooling plate cannot be guaranteed, is easy to expose casting defects after being worn or burned after being used for a period of time, and can cause water leakage and failure in a short time in a serious condition.
