Description
Technical field
The utility model relates to a kind of slag runner water cooler, belongs to metallurgy industry ironmaking technology field.
Background technology
In iron-smelting blast furnace production process, slag runner is unique passage of high-temperature liquid furnace slag (1400-1500 ℃) discharge, be related to stable, the direct motion of blast furnace operating, effect in blast furnace ironmaking process is very important, its chief component is the refractory materials (generally only comprising permanent layer and working lining) of different performance of inner side and the box hat in outside, the refractory materials of inner side directly contacts with high-temperature liquid furnace slag, and Service Environment is very severe.Slag runner in process, mainly stands the destruction of following several factors: the mechanical erosion of (1) high-temperature liquid state slag under arms; (2) chemical erosion of slag; (3) thermal shock that blast furnace intermittently causes during deslagging is corroded.Three kinds of factor alternating actions, strengthen mutually, greatly reduce the service life of slag runner.But along with the development of modern blast furnace technology, blast furnace presents obvious the Enlargement Tendency, go out the quantity of slag time constantly to extend, be accompanied by mechanical erosion and the chemical erosion of high temperature furnace slag, the Service Environment of slag runner further worsens, and has aggravated the destruction of slag runner.Current each iron work all proposes to require not 300,000 tons of iron influxs of damping down (in life cycle process must not molding repair) work-ing life, require very high, scene need to be keeped in repair slag runner frequently, both cost of labor, Material Cost had been increased, also limit furnace processor, caused larger financial loss to ironmaking enterprise.How further to improve the slag runner life-span, become the urgent technical barrier that vast ironmaking worker faces.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of slag runner water cooler.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of slag runner water cooler, comprises cooling matrix, water-cooled tube and Cast Steel Plate, it is characterized in that: the section of described cooling matrix is semicircle ring structure, comprises inner ring surface, outer ring surface, two semicircular ring sections and two rectangular cross-sections; On described inner ring surface, be evenly distributed with multiple dovetail grooves that be arranged in parallel; Described Cast Steel Plate geomery coordinates with cooling matrix phase, and lower surface is provided with the dovetail fin of many projections that match with dovetail groove on inner ring surface; Described cooling matrix penetrates inner evenly orthogonal coming and going from a rectangular cross-section and wears the water-cooled tube being connected, and the water-in of described water-cooled tube and water outlet are opened in respectively on two rectangular cross-sections.
Described slag runner water cooler, is characterized in that: between described cooling matrix, water-cooled tube and Cast Steel Plate, be that the micro-molten mode in surface is combined closely fixing.
Described slag runner water cooler, is characterized in that: described cooling matrix is oxygen free copper material.
Described slag runner water cooler, is characterized in that: described water-cooled tube is many, and material is wroughtsteel pipe.
As preferred version, described slag runner water cooler, is characterized in that: the cross section of described water-cooled tube is for oval, and the length ratio of oval-shaped minor axis and major axis is 0.5-0.7.
Beneficial effect: the slag runner water cooler that the utility model provides, the cooling matrix that adopts oxygen free copper to make, interior layout wroughtsteel pipe water-cooled tube, and the Cast Steel Plate being connected mutually by inner ring surface dovetail and the micro-melt-phase of oat tail groove structure is strengthened mechanical properties strength, have the following advantages: (1) cooling plate has adopted oxygen-free copper matrix, compared with plain cast iron cooling plate, the heat conductivility of copper is better.Promote on the whole the cooling power of cooling plate, and then can reduce the usage quantity of water coolant; (2) compared with fine copper cooling plate, avoided water-cooled tube that burn through easily occurs in castingprocesses, and the low problem of yield rate (fusing point of copper is about 1083 ℃, and the fusing point of steel is about 1530 ℃, so in castingprocesses, can there is not burn through when the steel pipe of imbedding runs into liquid copper); (3), compared with rolling fine copper cooling plate, water-cooled tube and the moulding of matrix one-step casting, reduced welding process, improved production efficiency, reduced production cost; (4) in the inside of copper matrix, imbed steel pipe, the mode of outside " interlock " Cast Steel Plate, has improved ability and the mechanical property of the resistance to deformation of cooling plate, and then extends the work-ing life of cooling plate.(5) Cast Steel Plate of copper matrix and outside " interlock " adopts the mode of physical connection, and transportation, the installation of product are all easier.
