Document《Blast furnace is not normal and accident treatment》(Zhang Shourong is in Zhong Jie etc., page 2013,15), describe what air port was tapped a blast furnace Method, is tapped a blast furnace from air port and there are many problems:1. air inlet and tapping hole are in same horizontal plane, because slag iron liquid level has reached To air port, the middle or small set of blast-furnace tuyere will be burned, and the replacing of middle or small set needs consuming time and manpower, not only increases blast furnace The expense of recovery, also extends the time of blast furnace recovery;2. big set, two sets of interior installation carbon brick sets, build refractory brick, air port and stokehold Iron tap channel or iron flask are connected etc., and outside work is relatively complicated;3. there is the possibility for pouring in down a chimney slag iron in air-supply air port.
Chinese patent literature CN201420323814.4, entitled, the interim iron mouthful device of gobbed up mainly uses height Clinker mouthful taps a blast furnace, and present large and medium-sized blast furnace does not set cinder notch, and this method has limitation.
Utility model content
The purpose of this utility model is to provide a kind of blast furnace crucibe for above-mentioned problem to freeze emergent tapping device, When iron mouthful can not discharge slag iron, emergent tapping hole is opened using interim tapping machine, cold slag iron is discharged in time, is substantially reduced extensive The multiple time, reduce the loss of the huge manpower and materials of enterprise.
Above-mentioned purpose is achieved through the following technical solutions:
Blast furnace crucibe freezes emergent tapping device, including be arranged between blast-furnace tuyere and blast furnace taphole it is emergent go out Tie Tong Road, it is described it is emergent go out Tie Tong road one section of carbon ramming mass passage and one section of carbon brick passage, institute are included by furnace outer wall to stove inwall Flange is welded with the furnace outer wall stated, described flange is outer to pass through fixture junction steel plate.
Described blast furnace crucibe freezes to be provided with cooling wall on the inside of emergent tapping device, described furnace outer wall, and described is cold But it is provided with cooling water pipe at wall.
Described blast furnace crucibe freezes emergent tapping device, and described fixture uses bolt.
Beneficial effect:
1. the utility model avoids cold slag iron from being discharged from formal iron mouthful, the new slag iron liquid level produced after the air blast of air port Air port is risen to, air port is all filled to dead, is forced to be tapped a blast furnace with air port or iron mouthful taps a blast furnace, not only resume speed is slow for both approaches, Substantial amounts of human and material resources and financial resources are also consumed, are lost huge.The utility model sets one to answer between blast furnace taphole and air port Anxious tapping hole, when the formal iron mouth of gobbed up can not tap a blast furnace, by interim tapping machine, opens this emergent tapping hole, discharge Cold slag iron by interim iron tap channel reach tap drain, the timely discharge of cold slag iron, heat and the heat of combustion of coke that air port is brought into, The cold slag iron of energy fast melt cupola well, accelerates conditions of blast furnace resume speed.
2. it is of the present utility model it is emergent in addition to Tie Tong road is from stove in stove, front half section uses carbon ramming mass, second half section profit With the carbon brick in blast furnace crucibe.Front half section iron mouth pore passage is tamped with carbon ramming mass, outside welded flange, when normally producing, will Bolt on flange is carried tightly, prevents from leaking coal gas herein, and emergent tapping hole is arranged between two pieces of cooling walls, cooling water pipe arc-like rows Putting the emergent tapping hole region of guarantee has enough intensities of cooling, and when normally producing, most time slag iron liquid level positions reach Less than the height of emergent tapping hole, it is ensured that the normal operation of safety at the emergent tapping hole of cupola well, it is not necessary to safeguard.
3. the utility model compares other two methods, when iron mouthful can not discharge slag iron, opened using interim tapping machine Emergent tapping hole, discharges cold slag iron, substantially reduces recovery time, reduce the loss of the huge manpower and materials of enterprise in time. Such as 4000m3When level blast furnace crucibe freezes, it is 5 days or so using this device blast furnace recovery time, is handled with other method, recovers Time is 15 days or so.If blast furnace produces iron for 9500t daily, ton iron profit is 1000 yuan, and recovering blast furnace using this device can To reduce loss 9500*(15-5)* 1000=95,000,000 yuan(The loss such as equipment, resistance to material and manpower is not included).
