Current in current subrack unit fully flow, and improve heat exchange cooling effect.
Further, the water knockout drum is diversion box or distributive pipe, is preferably diversion box.
Further, the water cooling subrack unit close to the one side of bath smelting furnace interior be rectangular surfaces or arcwall face, with
Adapt to the furnace type structure in different molten baths.
Further, N >=2, each water cooling subrack unit is arranged in parallel, and refractory material can be facilitated by being arranged in parallel
Build by laying bricks or stones.
Further, the refractory material is the one or more in castable, ramming mass, refractory brick.
Further, when refractory material is refractory brick, the spacing between the water cooling subrack unit is refractory brick standard
The integral multiple of size.
Further, hoisting mechanism is fixed on the water knockout drum, to facilitate hoisting transportation.
Further, the hoisting mechanism is lifting lug.
Further, the water cooling subrack element number is 1 ~ 5, and water cooling subrack group quantity is determined by superstructure height.
Further, the refractory material is if castable or ramming mass, and the spacing between water cooling subrack unit is according to work
The scouring intensity that is heated under condition empirically determines.
Preferably, single diversion box sets a water inlet and a water outlet, and entery and delivery port caliber is according to single group water cooling
Subrack quantity determines.
The utility model also provides a kind of bath smelting furnace, including top furnace wall structure as described above.
Compared with prior art, the beneficial effects of the utility model are as follows：
（1）Film-cooled heat is big, good cooling results；
（2）Intensity of cooling on the furnace wall structure unit area is high, and stability is good, and survivability is strong；
（3）The parameters such as water cooling subrack element number, size, shape, spacing can be adjusted as needed, ensure structure
While intensity, ensure cooling effect, improve the applicable surface of the top furnace wall structure；
（4）Have many advantages, such as to resist severe production status, service life long, energy-saving, when refractory material using cast or
It, can be with Rapid-Repair, so as to shorten the stop repairing time caused by top cooling furnace wall damage during ramming mass.
