Problems solved by technology
The disadvantage of the cast iron stave is that there is an air gap layer and an anti-carburization layer between the cast iron base material and the internal cooling water pipe, so that the heat cannot be conducted; the disadvantage of the cast steel stave is that the casting temperature is relatively high, and the distance between the cast steel base material and the water pipe The degree of fusion is difficult to control. If the degree of fusion is low, there will be a gap layer between the base metal and the water pipe. If the degree of fusion is too high, the cooling water pipe will lose its mechanical properties, and the water pipe will break if the cooling wall is slightly deformed. Slag skin maintenance, wear resistance and high temperature difference, and the price is also high

The invention discloses a novel cooling wall and belongs to the technical field of blast furnace equipment. The novel cooling wall comprises a first steel plate and a second steel plate, wherein the second steel plate and the first steel plate are mutually engaged, a copper pipe is arranged in a cavity between the second steel plate and the first steel plate, a gap formed between the second steelplate, the first steel plate and the copper pipe is filled with a high-heat-conductivity carbonaceous pressing material, the surface of the copper pipe is sleeved with a sleeve, and a first fixing bolt is commonly connected to the surfaces of the second steel plate and the first steel plate. The cooling wall has the advantages that the integral structure of the cooling wall does not need high-temperature casting, the interior of the copper pipe is almost not damaged, the mechanical property of a water pipe can be kept to the maximum extent, the second steel plate and the first steel plate canbe rolled steel plates with higher quality, and the heat of the second steel plate and the first steel plate can be transferred to the copper pipe more uniformly through the high-heat-conductivity carbonaceous pressing material, so that the cooling wall has the characteristics of copper and steel, and the integral heat conductivity is greatly improved.
Description
technical field [0001] The invention relates to the technical field of blast furnace equipment, and more specifically, relates to a novel stave. Background technique [0002] The blast furnace stave is one of the important equipments of the blast furnace. It is installed in the furnace shell. The efficient work of the stave is one of the key factors to maintain the longevity of the blast furnace. To maintain the efficiency of the stave, one is to maintain a strong cooling capacity of the stave itself, the other is to maintain the good mechanical properties of the base material of the stave, and the third is to maintain a reasonable internal structure of the stave. The currently used staves mainly include cast iron staves, cast steel staves and copper staves. The disadvantage of the cast iron stave is that there is an air gap layer and an anti-carburization layer between the cast iron base material and the internal cooling water pipe, so that the heat cannot be conducted; th...
