-1, be unfavorable for the efficient cooling of cooling stave.
The utility model content
In order to overcome the problem that prior art exists; The purpose of the utility model is to provide the new cast copper material of a kind of usefulness to replace the cast copper cooling wall of traditional cast iron materials; Water-cooled tube and cooling stave body are combined closely; Eliminate air gap, improved the performance of cast copper cooling wall, prolonged the work-ing life of metallurgy high temperature stove.
For achieving the above object, the utility model is to realize through following technical scheme:
A kind of cast copper cooling wall comprises cooling stave body and water-cooled tube, it is characterized in that described cooling stave body and water-cooled tube all processed by the cast copper material; The cooling stave body is a U-shaped; Water-cooled tube is positioned at the cooling stave body, also takes the shape of the letter U, and the water-cooled tube cross section is Long Circle; Fit tightly with the molten mode of surface micro with the cooling stave body, stretch out from two ends of the U-shaped of cooling stave body at its two ends.
Aforesaid cast copper cooling wall, the length ratio that it is characterized in that described oblong major axis and minor axis is 0.5～0.7.
Aforesaid cast copper cooling wall is characterized in that described water-cooled tube is many.
The beneficial effect of the utility model is: the utility model adopts the Long Circle water-cooled tube, has increased the cooling intensity to hot side, has improved the thermal conduction benefit; Adopt existing cast iron of cast copper material substitution and cast steel material to make cooling stave, can effectively avoid producing air gap between cooling stave body and water-cooled tube, prolonged the life-span of cast copper cooling wall life-span and then prolongation metallurgy high temperature kiln, save production cost; And make water-cooled tube and cooling stave body combine closely, improve the cast copper cooling wall cooling performance, improve the mechanical property of cast copper cooling wall.
