Description of drawings
Fig. 1 is the cross-sectional schematic of water-cooled described in the utility model ore deposit hot stove tapping hole structure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
Water-cooled described in the utility model ore deposit hot stove tapping hole structure as shown in Figure 1, is arranged on the hot stove in ore deposit, and the hot stove and accessory in this ore deposit has the hot stove furnace shell 7 in ore deposit, the anti-material 8 of furnace lining, and described furnace bottom 5 is a refractory material, and inwall 6 is the furnace wall carbon brick.This water-cooled ore deposit hot stove tapping hole structure comprises tapping hole converter nose 4, this tapping hole converter nose 4 closely contacts with tapping hole inner core 1, and run through by stream Tie Tong road, this tapping hole inner core 1 further is provided with water-cooled copper steel cooler 2 with tapping hole converter nose 4 peripheries, is filled with heat-conducting medium 9 between this water-cooled copper steel cooler 2 and the tapping hole inner core 1.
The water-cooled copper steel cooler 2 that is provided with outside above-mentioned tapping hole inner core 1 and the tapping hole converter nose 4 can be derived the heat of tapping hole inner core 1 rapidly, thereby the temperature of tapping hole is reduced, and uses to reach to prolong the hot stove tapping hole in the ore deposit purpose in service life.
Particularly, described tapping hole inner core 1 (is for example made for carbonaceous refractory, the carbonaceous refractory thermal conductivity factor that adopts is not less than the carbonaceous material of 60W/ (mk) (25 ℃ of room temperatures) or SiC, C composite), be provided with stream Tie Tong road in this tapping hole inner core 1, described heat-conducting medium 9 is the plain clay of highly-conductive hot carbon, and 2 in described water-cooled copper steel cooler is provided with water inlet and delivery port 3.Cooling water flow velocity in the described water-cooled copper steel cooler 2 is not less than 1.5m/s, the cooling water water temperature is not more than 40 ℃ and is advisable.The described heat that is arranged at tapping hole converter nose 4 and tapping hole inner core 1 is to conduct to water-cooled copper steel cooler 2 by heat-conducting medium 9, this water-cooled copper steel cooler 2 is that medium distributes heat by the circulating water of water inlet and delivery port 3 further again, thereby realizes the cooling to tapping hole.
Widen the view when tapping a blast furnace when the hot stove in ore deposit, the local temperature in the stream iron duct of tapping hole converter nose 4 and tapping hole inner core 1 reaches the temperature that flows out metal, slag liquid in the stove, can not influence normal flow iron.Because tapping hole inner core 1 outside is spread out of tapping hole inner core 1 heat by water-cooled copper steel cooler 2, makes tapping hole inner core 1 thermograde from inside to outside increase greatly, makes whole serviceability temperature be far smaller than the serviceability temperature of tapping hole in the prior art.In addition, do tapping hole inner core 1 owing to adopt the highly-conductive hot carbon cellulosic material, when its outside intensity of cooling acquires a certain degree, can form the solidified shell of layer of metal or slag at the stream iron duct of tapping hole converter nose 4 and tapping hole inner core 1 perisporium, as long as this solidified shell do not damage, then the tapping hole that is provided be have nonvolatil.
