Abstract
The utility model belongs to an improvement on an ironmaking blast furnace bottom cooling structure and particularly relates to an improved blast furnace bottom cooling structure comprising air cooling pipes uniformly distributed in the bottom of a blast furnace, wherein the air cooling pipes are internally provided with water cooling pipes with two sealed ends; each water cooling pipe located outside each air cooling pipe is provided with a water inlet and a water outlet; a sealing plate fixedly connected to an external port of each air cooling pipe is used for connecting and fixing the water cooling pipes; the sealing plate and a shell of the blast furnace are connected into a whole; the sealing plate is provided with a grouting hole and an air outlet; the grouting hole is provided with a grouting pipe with one end extending into the inner end of each air cooling pipe; and each air cooling pipe is internally provided with a thermocouple. The improved blast furnace bottom cooling structure is reasonable in structure and can be used for improving the cooling function of the bottom of the blast furnace, reducing the temperature of the bottom of the blast furnace, monitoring the temperature change at the bottom of the blast furnace and ensuring the safe operation of the bottom of the blast furnace.
Description
Technical field
The utility model belongs to the cooling structure of the improvement to iron-smelting blast furnace furnace bottom cooling structure, particularly a kind of improved Blast Furnace Bottom.
Background technology
In iron-smelting blast furnace maintenance process, find that the uniform forced air cooled tube of furnace bottom is because cupola well carbon brick subsides, cause forced air cooled tube distortion to subside, cooling air cannot carry out by furnace bottom forced air cooled tube cooling to furnace bottom, and there is very large hidden danger in the safe operation of cupola well therefore.Forced air cooled tube subsides and can cause furnace bottom forced air cooled tube cooling power to decline, as monitors not in placely, can be further worsens, and causes that forced air cooled tube stops up, cracking, finally may cause sudden burn-through of furnace hearth accident.
Utility model content
The purpose of this utility model is to provide a kind of cooling structure of improved Blast Furnace Bottom, it is rational in infrastructure, can improve the refrigerating function of Blast Furnace Bottom, reduces the temperature of Blast Furnace Bottom, and can monitor the temperature variation of Blast Furnace Bottom, ensure the safe operation of Blast Furnace Bottom.
The purpose of this utility model is achieved in that a kind of cooling structure of improved Blast Furnace Bottom, be included in the forced air cooled tube of uniform setting in Blast Furnace Bottom, the water cooling tube of closed at both ends is installed in forced air cooled tube, be positioned on the water cooling tube of forced air cooled tube outside water-in and water outlet are being set, shrouding affixed in the external port of forced air cooled tube is connected and fixed water cooling tube, shrouding and last furnace shell are connected as a single entity, grouting mouth and air outlet are being set on shrouding, the grout pipe that one end is being set gos deep into forced air cooled tube the inner in grouting mouthful is installed with thermopair in forced air cooled tube.
The utility model is transformed enforcement successively to 20 of Blast Furnace Bottom forced air cooled tubes, to the water cooling tube of closed at both ends be installed in forced air cooled tube, water-in and water outlet are being set on the water cooling tube being positioned at outside forced air cooled tube, shrouding affixed in the external port of forced air cooled tube is fixed water cooling tube, shrouding and last furnace shell are connected as a single entity, grouting mouth and air outlet are being set on shrouding, on grouting mouth, the grout pipe that gos deep into water cooling tube the inner are being set, thermopair is being installed in forced air cooled tube.Be in the milk, grouting requires the air outlet grout of must being in the milk, and after the grout of grouting air outlet, tightens thermopair base, connects the pipeline of water cooling tube import and export.
The utility model is owing to taking above technical scheme, and it has the following advantages:
1, recovered the function at the bottom of the cool furnace of furnace bottom forced air cooled tube.
2, by the air-cooled water-cooled that changes into, improve the cooling power of furnace bottom, force cooling to furnace bottom subsidence area.
3, ensured the safe operation of State of Blast Furnace labour later stage cupola well.
4, simple in structure, easy to implement.Can carry out gradation transformation to 20 forced air cooled tubes of furnace bottom implements.
5, the later stage is easy to safeguard, checks.
The utility model is rational in infrastructure, has realized the refrigerating function that improves Blast Furnace Bottom, has reduced the temperature of Blast Furnace Bottom, and has realized the temperature variation of Blast Furnace Bottom is monitored, and has ensured the safe operation of Blast Furnace Bottom.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is structural representation of the present utility model.
