Description
Technical field
The utility model relates to oxygen-enriched bottom-blowing molten pool melting technology field, especially relates to a kind of bottom convertor charge door protective device.
Background technology
Oxygen-enriched bottom-blowing molten pool melting technology is widely applied in heavy nonferrous smelting field, its primary body equipment is bottom convertor, existing bottom convertor Problems existing is: it is mainly used in plumbous smelting, and when Copper making, smelting temperature is relatively high, the lower end of feed pipe water jacket touches high temperature, very easily burn leakage accident, refractory material and operating mode in bottom convertor can be caused to produce significant damage, can blast time serious, there is larger potential safety hazard.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of long service life, the bottom convertor charge door protective device that reliability is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of bottom convertor charge door protective device, be installed on the furnace wall of bottom convertor, furnace wall has furnace shell; It also has one to run through to be installed on the feed pipe on furnace wall, to be set on feed pipe outer wall and to be positioned at the annular clip slot of feed pipe near inwall one end, furnace wall, and being set in the ring-shaped water jacket on feed pipe outer wall; Magnesium chromium matter ramming mass is filled in described annular clip slot; Described ring-shaped water jacket is provided with water inlet pipe and outlet pipe.
Preferably, described ring-shaped water jacket is bolted to connection on furnace shell.
Preferably, described annular clip slot is connected with feed pipe by welding.
Preferably, feed pipe is fixedly connected with furnace shell by bolt.
Preferably, the length of described annular clip slot is 150mm-200mm.
Compared with prior art, tool has the following advantages the utility model:
The utility model is in normal productive process; top (i.e. charging aperture porch) takes soft water to cool; bottom (one end close to furnace wall inwall) arranges refractory material magnesium chromium matter ramming mass; effectively can protect feed pipe not easily Yin Gaowen and splash slag felt jam occurs; ring-shaped water jacket can be avoided to be burnt simultaneously; stop leakage accident to occur, guarantee production safety.
