Abstract
The utility model relates to a copper cooling wall with a good cooling effect and combined plate and wall for a furnace bosh of a blast furnace, which comprises a copper cooling wall body, a copper water cooling pipe arranged in the copper cooling wall, a water inlet and a water outlet of the copper water cooling pipe, a connection hole, a dovetail groove in the copper cooling wall, and reinforcing copper water cooling pipes, and is characterized in that at least two reinforcing copper water cooling pipes are arranged between the water inlet pipe section and the water outlet section of the copper water cooling pipe in the copper cooling wall, and the cross section of each reinforcing copper water cooling pipe is oval. According to the copper cooling wall, by changing the shapes of the reinforcing copper water cooling pipes and properly adding the reinforcing water cooling pipes, the heat exchange area of the reinforcing copper water cooling pipes and the copper cooling wall is increased, further, the cooling effect is reinforced, and further, the service life of the cooling wall of the furnace bosh of the blast furnace is prolonged.
Description
Technical field
The utility model relates to a kind of blast furnace cooling stave, specifically belongs to the copper cooling wall of the large blast furnace bosh use with soft water airtight circulating cooling system.
Background technology
There are some researches show that the deteriorated major cause of spheroidal graphite cast iron is CO
2Intrusion, CO
2The beginning temperature spot that reacts with graphite in the matrix is 709 ℃, and temperature is higher, and speed of response is faster.Contain about CO of about 20% in the blast furnace gas
2, cooling stave and CO
2The chance of contact is a lot, therefore theoretically, works safely and reliably for guaranteeing cooling stave, and the maximum operating temperature of cooling stave should be lower than 709 ℃, can not be for a long time above 770 ℃.
For 2500m
3Above large blast furnace, the worst position of blast furnace cooling stave Working environment is (being the blast-furnace bosh position) at the following position of soft melt zone, temperature is higher than 770 ℃ far away in this regional stove, about l100～the l300 of this regional temperature ℃, near the air port even can reach more than l500 ℃, adopt the large blast furnace of full cooling stave cooling, after the blow-on about 10 years, bosh, restoration of lower stack cooling wall breakage rate is generally higher, sometimes the water pipe that has up to 60% goes wrong, in order to reduce the cast-iron cooling wall breakage, mostly adopt copper cooling wall to cool off at bosh in recent years, as publishing " the novel blast-furnace cooling apparatus-copper cooling wall " on bao steel technology January calendar year 2001, the thermal conductivity of having introduced copper in the document is about 10 times of cast iron, so the copper cooling wall cooling power is superior, but because bosh and cupola well intersection exist the difference of structure, be slag iron easily gather the district, can not guarantee still that even so the bosh copper cooling wall does not go wrong.
In order to address the above problem, at present both at home and abroad in the work of mainly having done two aspects aspect the cooling power that improves the bosh cooling stave, on the one hand the cooling stave material is converted to copper (rolling or casting) by cast iron, on the other hand by improving cooling wall structure, lengthen cooling stave length, increase boss in the bosh bottom and strengthen cooling to bosh cupola well junction, but these improve with respect to abominable bosh Working environment abusive language, obtained certain effect, but bosh cupola well joint portion still aobvious cooling power is not enough, can not contain the breakage of bosh cooling stave.
The utility model content
The purpose of this utility model is to provide a kind of energy by changing the shape that strengthens the copper water cooling tube, the heat exchange area that strengthens copper water cooling tube and copper cooling wall is increased, and further strengthen cooling performance, and then improve the bosh blast furnace copper cooling stave of the good wooden partition combination of a kind of cooling performance in work-ing life of blast-furnace bosh cooling stave.
Realize the technical measures of above-mentioned purpose:
The bosh blast furnace copper cooling stave of the wooden partition combination that a kind of cooling performance is good, by the dovetail-indent on copper cooling wall body, the water-in that is contained in copper water cooling tube in the copper cooling wall, copper water cooling tube and water outlet, connecting hole, the copper cooling wall, strengthen the copper water cooling tube and form, it is characterized in that: be provided with at least two between the water-in pipeline section of the copper water cooling tube in copper cooling wall and the water outlet pipeline section and strengthen the copper water cooling tube, the cross-sectional shape that strengthens the copper water cooling tube is oval.
The utility model strengthens the copper water cooling tube by changing the shape that strengthens the copper water cooling tube and suitably increasing, and the heat exchange area that strengthens copper water cooling tube and copper cooling wall is increased, and further strengthen cooling performance, and then improve the work-ing life of blast-furnace bosh cooling stave.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: 1-copper cooling wall body, 2-copper water cooling tube, 3-water-in, 4-water outlet, 5-connecting hole, 6-dovetail-indent, the 7-oval copper water cooling tube that strengthens.
Embodiment
Be described further below in conjunction with accompanying drawing:
The bosh blast furnace copper cooling stave of the wooden partition combination that a kind of cooling performance is good is by the dovetail-indent 6 on copper cooling wall body 1, the water-in 3 that is contained in copper water cooling tube 2 in the copper cooling wall 1, copper water cooling tube 2 and water outlet 4, connecting hole 5, the copper cooling wall 1, strengthen copper water cooling tube 7 and form.Between water-in 3 pipeline sections and water outlet 4 pipeline sections of its copper water cooling tube 1 in copper cooling wall 1, casting is buried two or three underground and is strengthened copper water cooling tube 7, and 7 castings of enhancing copper water cooling tube are buried radical underground and determined with the size of blast furnace copper cooling stave and the size of caliber according to bosh; The cross-sectional shape that strengthens copper water cooling tube 7 is oval.Cross-sectional shape is oval-shaped enhancing copper water cooling tube 7 owing to increase with the contact area of copper cooling wall, so that heat exchange area increases, so can strengthen cooling performance to copper cooling wall.
Claims (1)
1. the bosh blast furnace copper cooling stave of the wooden partition combination that a cooling performance is good, by the dovetail-indent on copper cooling wall body, the water-in that is contained in copper water cooling tube in the copper cooling wall, copper water cooling tube and water outlet, connecting hole, the copper cooling wall, strengthen the copper water cooling tube and form, it is characterized in that: be provided with at least two between the water-in pipeline section of the copper water cooling tube in copper cooling wall and the water outlet pipeline section and strengthen the copper water cooling tube, the cross-sectional shape that strengthens the copper water cooling tube is oval.
