Background technology
The refrigerating unit of blast furnace mainly is divided into two kinds: first kind for carrying out point type refrigerative cooling plate to furnace wall in the body of heater that inserts blast furnace; Second kind for carrying out face formula refrigerative cooling stave to furnace wall on the furnace shell inner side-wall that covers blast furnace.For adapting to blast furnace longevity, the cooling stave that blast furnace uses is brought in constant renewal in and is regenerated.Only, develop into the very high copper cooling wall of thermal conductivity from cast-iron cooling wall and steel cooling wall from using the material aspect.Copper cooling wall has cast copper cooling wall, forging or rolled copper slab boring formula cooling stave.Wherein forge or the rolled copper slab cooling stave with its metallographic structure densification, intensity height, thermal conductivity is good and be extensive use of.
Be commonly referred to hot side at copper cooling wall away from the surface of blast furnace inner side-wall, copper cooling wall is commonly referred to huyashi-chuuka (cold chinese-style noodles) near the surface of blast furnace inner side-wall.Usually offer the dovetail-indent of some suspension slags that are parallel to each other on the surface of hot side, in copper cooling wall, offer some be parallel to each other cooling-water duct, water coolant flows in cooling-water duct blast furnace is cooled off, the surface of huyashi-chuuka (cold chinese-style noodles) then is welded with water inlet pipe and rising pipe, and water inlet pipe and rising pipe are communicated with cooling-water duct respectively.
As shown in Figure 1, existing copper cooling wall, inlet or outlet that its water pipe (water inlet pipe, rising pipe) inserts cooling-water duct usually are welded on the huyashi-chuuka (cold chinese-style noodles) then, and water pipe is subjected to external force and has only weld seam stressed as the time spent, therefore is easy to generate the crack, causes leaking.Under the certain prerequisite of copper cooling wall wall thickness, offering of cooling water channel will reduce the bulk strength of copper cooling wall, especially the commissure of water inlet pipe, rising pipe and huyashi-chuuka (cold chinese-style noodles), because the huyashi-chuuka (cold chinese-style noodles) of copper cooling wall body is shorter usually to the distance of cooling-water duct, so the degree of depth of bevel for welding is dark inadequately, this has just caused the strength ratio of weld seam relatively poor, after being subjected to bigger external force effect for a long time, be more prone to produce the crack, cause leaking, even the whole fracture from the commissure.
Summary of the invention
The objective of the invention is prior art is improved, a kind of copper cooling wall of pipe arrangement reinforcing structure is provided, can effectively improves the stressing conditions of water pipe, effectively anti-antipriming pipe produces the crack, and can effectively control manufacturing cost, the technical scheme of employing is as follows:
The copper cooling wall of pipe arrangement reinforcing structure of the present invention, comprise the copper cooling wall body, at least one water inlet pipe and at least one rising pipe, have at least one cooling-water duct in the copper cooling wall body, described water inlet pipe is welded on the huyashi-chuuka (cold chinese-style noodles) of copper cooling wall body and water inlet pipe connects the inlet of cooling-water duct, described rising pipe is welded on the copper cooling wall body huyashi-chuuka (cold chinese-style noodles) and rising pipe connects the cooling-water duct outlet, it is characterized in that: described water inlet pipe front end outer side wall is provided with first outside screw, cooling-water duct inlet inner side-wall is provided with first internal thread, and water inlet pipe inserts in the cooling-water duct inlet and with cooling-water duct and enters the mouth inner side-wall by being threaded; Described rising pipe front end outer side wall is provided with second outside screw, and cooling-water duct outlet inner side-wall is provided with second internal thread, and rising pipe inserts in the cooling-water duct outlet and with cooling-water duct and exports inner side-wall by being threaded.Because being threaded has significantly increased reliability and compactness that water pipe is connected with the copper cooling wall body, water pipe is difficult to separate with copper cooling wall body connection portion, can prevent the antipriming pipe exposed parts be subjected to the external force effect after water pipe from the copper cooling wall body, extract, most power can be shared in the threaded connection place, therefore significantly increased the stress point of water pipe, effectively improve the stressing conditions of water pipe, made water pipe stressed more even.After having adopted the structure that is threaded, alleviated the power that weld seam is subjected to greatly, defectives such as crack, fracture appear in the very effective weld seam of having avoided.
