A kind of copper cooling plate
Technical field
It the utility model is related to a kind of smelting furnace body cooling device, more particularly to a kind of copper cooling plate.
Background technology
Coldplate is one of blast furnace cooling device more early occurred, and the general principle of coldplate is come cold by point cooling
But refractory material bricking and it is remained certain thickness, and then pass through refractory material bricking and protect last furnace shell.Therefore, it is cold
But plate is better to the cooling effect of refractory material bricking, more can effectively extend the service life of refractory material bricking, and then influence
The longevity of blast furnace.
The coldplate of domestic and international most of blast furnaces at present is fine copper or copper alloy using high heat conduction as coldplate sheet
Body, there is excellent heat conductivility, higher heat flow rate per unit area and thermal shock impact can be born.
Traditional copper cooling plate, mainly there are the copper cooling plate of cast structure, the copper cooling plate of pipe laying cast structure, copper pipe and copper
Coldplate, the copper cooling plate of copper coin drilling weldering stopper structure of plate/welded-steel plate construction.The major technique of traditional copper cooling plate is difficult
Point has:
As shown in Figure 1-2, the copper cooling plate of cast structure, including coldplate body 1, water channel 2 and water hole 3, due to casting
Easily there are the quality problems such as loose, stomata, crackle and leak in the reason for moulding process, coldplate body 1, and not only thermal conductivity is inclined
Low, product qualified rate is relatively low.
As shown in figure 3, the copper cooling plate of pipe laying cast structure, including coldplate body 1, water channel 2 and copper pipe 4, due to pouring
