Abstract

The utility model discloses a cooling device, and particularly relates to a copper cooling ring which can maintain and even enhance the cooling intensity of a copper cooling plate and overcome the casting defects of the copper cooling plate; the copper cooling ring comprises one or more copper pipe(s), and is characterized in that the copper pipe(s) is/are bended to form one or more cooling channel(s); and the copper pipe(s) is/are externally covered with refractory material and molded with the refractory material into a whole body. As the one or more cooling channel(s) can be formed, the cooling intensity of the copper cooling ring is better than that of the copper cooling plate; and the copper pipe(s) is/are made by drawing or extruding, so that the copper cooling ring eliminates the defects of loose material, the casting defects, water leakage hidden trouble, low finished product ratio and the like of the copper cooling plate, and saves more copper material compared with the copper cooling plate.

Description

The copper air ring

Technical field

The utility model relates to a kind of cooling device, relates in particular to a kind of cooling device that is used on blast furnace, the hot stove in ore deposit and other high temperature furnace.

Background technology

Blast furnace, the hot stove in ore deposit and other high temperature furnace are in the stove under the adverse circumstances of high temperature because vigorous reaction takes place in the stove, in order to protect body of heater, adopt the mode of copper cooling plate and refractory material combination to form inner lining of furnace in the furnace shell of being everlasting.The operation principle of copper cooling plate is to adopt water stream channel to use the water of high specific heat capacity to take heat out of body of heater to reach cooling effect, the temperature of the refractory material around the copper cooling plate is lowered, the infringement that makes inner lining of furnace be subjected to thermal stress alleviates, and has prolonged the life-span of inner lining of furnace.But because copper cooling plate has casting flaws such as pore, slag inclusion for casting cooling device material is loose, have the hidden danger of leaking, yield rate is very low.Therefore, jump out the limitation of pattern, catch the fundamental requirement that reaches the cooling purpose, need a kind of new cooling device can keep even strengthen the intensity of cooling of copper cooling plate, can overcome its defective again, and save the copper material.

The utility model content

The purpose of this utility model is to provide a kind of intensity of cooling that can keep even strengthen copper cooling plate can overcome cooling device---the copper air ring of its casting flaw again.

To achieve these goals, the utility model provides a kind of cooling device---the copper air ring, comprise one or more copper pipe, and it is characterized in that: described copper pipe is bent into one or more cooling duct, and the copper pipe outside can coat refractory material and be shaped to one.

Preferably, described copper pipe can be a flat tube.

The utility model is compared with existing copper cooling plate, and one, copper air ring adopt one or more copper pipes to bend and form, and form one or more cooling duct, and its intensity of cooling can meet or exceed the cooling of copper cooling plate; Its two because copper pipe forms for drawing or extruding, eliminated defectives such as the copper cooling plate material is loosened, had casting flaw, has the hidden danger of leaking, yield rate is low; Its three, the streamline transition press at the bent turning of copper pipe, local resistance loss is little, can carry out the many places bending, has eliminated copper cooling plate water and has flowed in cooling water chamber and cause the bigger problem of resistance damage; Its four, copper pipe coats refractory material outward and becomes one, and can make bulk and install, and directly furnace lining is also laid, and is simple and convenient; Its five, the copper product that the copper air ring is compared copper cooling plate consumption will reduce a lot, and for this noble metal of copper, also just is equivalent to save a large amount of costs.

By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
