Abstract
The utility model provides a blast furnace multi-pipe reinforced cooling plate, which consists of a copper plate wall, a wear-resistant alloy lining plate, a water cooling pipe and nickel-containing heat-resistant ribs; the upper surface and the lower surface of the four copper plate wall frames are respectively welded with wear-resistant alloy lining plates to form a hollow flat box body, at least 4U-shaped water cooling tubes which are communicated with industrial water or soft water are uniformly distributed in the flat box body, two ends of each water cooling tube extend out of the copper plate wall on one side, and at least 2 nickel-containing heat-resistant ribs are additionally arranged between the water cooling tubes. The utility model discloses be convenient for installation and change, in blast furnace daily production, can take out the heat with great ability from the stove to build suitable blast furnace operation stove type, can prolong cooling plate life 2 years, promote the blast furnace and utilize the coefficient more than 0.1, effectively reduce the blast furnace and maintain and the iron-making cost.
Description
Technical field
The utility model belongs to cooling equipment for blast furnace field, particularly a kind of blast furnace cold but plate adopting multitube cooling, surface abrasion resistance.
Background technology
In recent years, while blast furnace (BF) expansion and strengthening smelting, breakage of furnace body especially cooling apparatus damage phenomenon is also significantly rising, furnace lining corrodes the rising of aggravation and furnace wall heat release rate, cause the damaged and brick lining of stack stave etc. to corrode the phenomenon such as serious to happen occasionally, the normal production of serious restriction blast furnace.To this, a lot of enterprise and institute develop a series of cooling apparatuss adapting to different smelting condition and heat size, and define the two class Development patternss improved with material improvement and the type of cooling, as highly purified copper material is used for cooling stave and cooling plate, its thermal conductivity is increased considerably, comparatively pass by blast furnace use plain cast iron cooling apparatus exceed an order of magnitude, and cooling apparatus protection slag crust can be formed fast, extend the work-ing life of cooling apparatus, or employing Large Diameter Pipeline, the cooling provision of high flow rate, taking out of of furnace heat is realized by increasing heat-eliminating medium, protection body of heater cooling equipment.But because more blast furnace forms by organizing obform body, partial portion is as the combining site of furnace bosh and furnace bosh and restoration of lower stack, for building the needs of the optimum operation type of furnace, the use of obvious cooling plate comparatively cooling stave will be more reasonable, but because the maturation of cooling stave is applied, mask the development that some current cooling plates use, the cooling plate causing present stage to adopt chooses structure design from material still certain flaw, technique also exists the place that some have band to improve.
Summary of the invention
The utility model provides a kind of blast furnace multitube to strengthen cooling plate, its object is to the length of service extending cooling plate, increases carry heat output capacity, improve cooling performance, reduce maintaining blast furnace and ironmaking cost.
For this reason, the utility model takes following technical solution:
A kind of blast furnace multitube strengthening cooling plate, is made up of copper coin wall, anti-wear alloy lining board, water cooling tube and nickel-containing heat resisting rib; Anti-wear alloy lining board is welded with respectively at the upper and lower surface of four pieces of copper coin wall frameworks, form the flat casing of a hollow, " U " shape water cooling tube that at least 4 are connected with service water or soft water is evenly equipped with in flat casing, water cooling tube two ends lean out outside a side copper plate wall, add at least 2 nickel-containing heat resisting ribs between water cooling tube.
Described copper coin wall thickness is 1 ~ 10mm.Anti-wear alloy lining board length is 200 ~ 800mm, and width is 100 ~ 600mm, and thickness is 70 ~ 150mm.Water cooling tube diameter is 10 ~ 40mm.
The beneficial effects of the utility model are:
The utility model multitube strengthening cooling plate, be convenient to install and change, in the daily production of blast furnace, heat can be taken out of in stove with larger ability, thus build the suitable blast furnace operating type of furnace, 2 years work-ing life of cooling plate can be extended, promote the capacity factor of a blast furnace more than 0.1, effectively reduce maintaining blast furnace and ironmaking cost.
