Abstract
The utility model relates to a copper plate cooling rod which is used for cooling the furnace wall of an ironmaking blast furnace. The front section of a barrel body of the utility model is made of pure copper plates. According to different heat flow intensities which acts on the parts of the cooling rod, four kinds of different water flow speed are correspondingly designed. Under the bad working conditions that firebricks of a furnace body are badly eroded and protective slag crusts are shed, the copper plate cooling rod is not burnt out, so that the regular production of the blast furnace is maintained.
Description
The utility model relates to a kind of copper coin cooling stick, particularly blast furnace body cooling apparatus.
The purposes of cooling stick is; After the original cooling apparatus of blast furnace (cooling stave) damages, need not blowing-out remove original cooling stave, as long as perforate on former cooling stave is inserted in the furnace wall with a plurality of cooling sticks, just can replace the function of original cooling stave.At present, known cooling stick adopts the cast copper cylindrical shell, and the copper content of cast copper is low, and compactness is poor, and thermal conductivity is also poor.Cooling stick inside is cavity structure in addition, and this can not adapt to the cooling stick operating mode that the ecto-entad heat flow rate per unit area increases gradually in blast furnace.Particularly collapse the material working of a furnace at blast furnace, the protective layer slag crust big area of body of heater internal surface comes off, and the enormous impact hot-fluid of instantaneous generation can burn cooling stick very soon, jeopardizes the blast furnace ordinary production.
The purpose of this utility model provides a kind of copper coin cooling stick, and not only heat conductivility is good for it, and has four kinds of different flow velocities, can adapt to the cooling stick operating mode that the ecto-entad heat flow rate per unit area increases gradually in the blast furnace furnace wall.
The utility model is achieved in that the cooling stick leading portion is a frustum of a cone cylindrical shell shape, makes of the copper coin of copper content 〉=99.90%.The cooling stick back segment is a cylindrical tube, back segment has inlet tube and outlet tube and grout pipe, with different spacing seven similar spiral shape dividing plates are set on the water inlet pipe outer wall of insertion inner barrel, space in the leading portion cylindrical shell is divided into eight compartments, this spacing is increased to the back-end gradually by the cooling stick front end, its function is the flow direction and the flow velocity of restriction water coolant, is 2.08m/s by the first compartment water speed behind the forward direction; Second and third, four compartment water speed is 1.5m/s; Five, six, seven compartment water speed is 1.2m/s; The 8th compartment is that cooling stick back segment cavity place water speed is 0.735m/s.The copper coin cooling stick of this kind structure, when service discharge is 12t/h its cooling intensity can 〉=8 * 10
6Kj/m
2.h.c, be enough to resist because blast furnace collapses the enormous impact heat flow rate per unit area that forms when material causes slag crust all to come off greatly.Inside and outside cooling stick being fixed on make simultaneously on the furnace shell blast furnace, keep air-tight state that the flange of a band grout pipe is set in copper coin cooling stick and furnace shell connection place, after cooling stick and furnace shell are fixing, by grout pipe pressure injection refractory mortar in stove, to fill the hole between cooling stick and body of heater.The copper coin cooling stick is except that leading portion, and miscellaneous part all adopts ordinary low-carbon steel to make.The argon arc welding is all adopted in the connection place between each parts of copper coin cooling stick.
Owing to adopt such scheme, the heat conductivility of copper coin cooling stick is good, and (λ 〉=300/m.s.c), and have four kinds of different flow velocities has realized good cooling, reduces resistance again, reduces pressure of supply water, save energy.
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1: the longitudinal section structural map of copper coin cooling stick:
The vertical view of Fig. 2: Fig. 1:
The left view of Fig. 3: Fig. 1.
As shown in Figure 1, the leading portion 1 of copper coin cooling stick is a frustum of a cone cylindrical shell shape, and cooling stick back segment 3 is a cylindrical tube, and back segment 3 connects with rising pipe 7, and connects with water inlet pipe 2 by top cover 6.Water inlet pipe 2 outer walls that insert leading portion 1 inner barrel are provided with 7 spiral septums, and space in leading portion 1 cylindrical shell is divided into eight compartments, and this spacing is increased to the back-end gradually by the cooling stick front end.Cooling stick leading portion 1 and back segment 3 connection places are provided with the flange 4 of a band grout pipe 5.Except that cooling stick leading portion 1 adopted the copper coin making of copper content 〉=99.90%, other parts all adopted general carbon steel to make, and the argon arc welding is all adopted in each parts connection place of cooling stick.
Water coolant enters in the cooling stick by water inlet pipe 2 in Fig. 1, at first arrive front end first compartment of leading portion 1, the similar spiral passage that forms along with dividing plate enters second and third successively then, four, five, six, seven compartments enter the 8th compartment at last, flow velocity meets the requirement of the interior actual condition of blast furnace to cooling apparatus by progressively reduce backward.
The utility model copper plate cooling rod, it is strong to be issued to cooling in the lower situation of pressure of supply water Degree is best, and prolong service life, the effect of energy savings.
Claims (2)
