Description of the invention (1) Field of the invention: The present invention generally relates to a condensation plate for a metallurgical furnace and a method for manufacturing the condensation plate. BACKGROUND OF THE INVENTION: Condenser plates (also known as horizontal plates) have been used in blast furnaces for more than a hundred years. These condensation plates are arranged on the inside of the furnace body shield and have internal cooling ducts connected to the cooling system of the metallurgical furnace. The surfaces of the condensing pipes facing the interior of the furnace are lined with refractory material. Different methods for manufacturing such a condensation plate are explained here. According to the first method, a sharp mold for sharply forming a 1-plate condenser body is provided with one or more sand cores used to form the internal cooling duct. Liquid cast iron is then poured into the mold. Disadvantages of this method are that mold sand is difficult to remove from the cooling ducts and / or cooling ducts made of cast iron cannot usually be properly formed and the cooling ducts are often not tight enough. In order to avoid the above disadvantages, I recommend that the formed steel pipe be placed in a mold and the liquid cast iron be injected around the steel pipe. However, these condenser plates have proven to be functionally inadequate. In fact, as carbon diffuses from the cast iron to the steel pipe, the steel pipe becomes brittle and may crack. The contact between the condensing plate and the condensing plate cast body will also cause cracks on the condensing plate cast body. The main reason is the difference in the thermal expansion coefficients of the two materials. In order to avoid the above mentioned on the condensing steel pipe and the condensing cast body 3 * »_____________ # il (Please read the precautions on the back before filling in this page) Order: 丨 Line · This paper size applies to Chinese National Standards (CNS) A4 specification (210 X 297 mm) 512174 A7 _____B7 __ 5. The cracks in the description of the invention (i), we suggest that we can provide a formed steel pipe with a coating, which is used to prevent carbon diffusion and prevent metallurgical bonding Between cast iron and the steel pipe. In addition, as a result of the casting, a small air gap can be generated between the steel pipe and the condensing plate casting body, so that the steel pipe and the condensing plate casting body can be individually and independently expanded. However, due to the isolation effect of the small air gaps mentioned above, these condensation plates have the disadvantage of poor heat transfer coefficient. Copper condenser plates have been developed as an alternative to cast iron condenser plates. So far, several production methods have been provided for the manufacture of copper "transverse plates". ○ At first, I tried to make copper condensation plates by casting. The internal cooling duct was formed by a mold located in the mold. Sand heart. However, as the cast copper plate usually has small holes and pores, it has a relatively negative impact on the service life of the copper plate, and the mold sand is difficult to remove from the # duct, and / or the cooling duct made of copper is not suitable. Ground forming, so this concrete manufacturing method has proven to be practically infeasible. Patent No. GB-A-1571789 proposes that when the condensing plate is cast in cast Fengmo, a sand metal core is replaced by a shaped metal tube coil made of copper or high-grade steel. This coil is formed integrally with the condensing plate casting body cast into the mold and forms a spiral cooling duct. Such a manufacturing method is not practically feasible, especially because the pores and pores generated by copper cannot be effectively prevented in this manufacturing method. From Patent No. DE-A-2907511, a condensation plate made of forged or lightly rolled copper ingots is known. The cooling duct is a blind hole obtained by mechanical drilling in a rolled copper ingot. With these condensation plates, the above 4 paper sizes are applicable to the Chinese National Standard (CNS) A4 specification (210 x 297 cm) (Please read the precautions on the back before filling this page)

Description of the invention (3) ‘The disadvantages of casting are avoided. In particular, the small holes and pores in the condensation plate have been virtually eliminated. Due to the complicated, time-consuming and expensive drilling of cooling ducts, the manufacturing cost of these condensation plates becomes quite high. Patent No. WO-98 / 30348 proposes the casting of a preformed condensing plate with the help of a continuous mold, in which rod-shaped inclusions inside the casting duct will create a duct that flows in the direction of continuous casting. The ducts form cooling ducts in the finished condensing plate. Although copper condensing plates generally have better thermal conductivity than cast iron condensing plates, copper condensing plates are far less wear-resistant than cast iron condensing plates. Therefore, the copper condensing plate cannot be arranged in the area of the furnace body in the condensing plate which must withstand strong mechanical stress. In addition, copper condenser plates are more expensive than cast iron condenser plates. Object of the invention: The object of the present invention is to provide a condensing plate which can be easily manufactured and has good abrasion resistance and low thermal resistance. This project was obtained through a condensing plate such as the scope of patent application No. 1 and a manufacturing method such as the scope of patent application No. 8 or 14. SUMMARY OF THE INVENTION According to the present invention, a method for manufacturing a condensation plate is proposed. In the first method step, a mold for casting a condensing plate casting body is provided. Then, at least one condenser tube is arranged in the mold.赞许 The praise is that the condenser tube is made of copper or copper alloy. Secondly, liquid iron metal is injected around the condensing tube in the mold. This method has been proven to be easy to implement.

The first advantage of copper or copper alloy condensers is that they have better thermal conductivity than traditional steel pipes. Therefore, a better result can be obtained between the condensing plate casting body and the cooling fluid flowing through the condenser tube. Heat Conduction. Another and even more important advantage is the avoidance of small air gaps around the condenser tube. In fact, copper and copper alloys are more ductile than steel. Later, when the condensing tube is subjected to mechanical stress due to the thermal expansion of the cast body, the condensing tube will be relatively easy to deform, unlike the steel tube. In addition, a tight fit is preferred between the copper pipe and the casting surrounding the condensing pipe so that the cooling efficiency of the condensing plate can be increased. As a result, the cooling plate of the present invention has improved cooling efficiency. In addition, the condensing plate according to the present invention also has good abrasion resistance and increased service life, so that the maintenance cost of the metallurgical furnace can be reduced. The temperature of the condensing tube may be controlled to be better during production. The above situation can be accomplished by generating a fluid to flow through the condenser tube. If the condensing tube is to be heated, for example, the heat flow can be circulated through the condensing tube before the liquid iron metal is injected. The result of heating the condenser tube allows to avoid the occurrence of thermal shock when injecting liquid iron metal, and also to avoid and / or remove the copper oxide layer formed on the surface of the condenser tube. If the condenser tube is to be cooled, i.e. when liquid iron is injected, cold flow can be circulated through the condenser tube. Λ On the other hand, by storing liquid metal with high heat capacity in the condensate tube before injecting liquid iron metal into the mold, the condensate tube can be prevented. 6 This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297) Mm> 512174 A7 __ B7 ____ V.

As a result, in order to achieve the same purpose of increasing heat exchange efficiency, the shape of the inner and outer surfaces of the condensing tube may be selected. To provide the outer perimeter length that is as large as possible: the ratio of the inner cross section. According to another aspect of the present invention, another method for manufacturing the condensation plate for a metallurgical furnace is proposed. In the first stage, a first mold for casting a shaped condensate plate body is provided, and at least one condensing pipe is disposed in the mold. It is praised that the condenser tube is made of copper or copper alloy. Liquid iron metal is then injected into the first mold, surrounding the periphery of the at least one condenser tube, while allowing the liquid iron metal to solidify.

Then, the liquid iron metal is injected into the mold and surrounds the periphery of the formed condensing plate casting body having the casting-completed condensing tube. Before the liquid ferrous metal is injected into the second mold, it is preferred that the condensing plate cast body having the casted condensing tube can be heated to an outer surface temperature of approximately the melting point of the ferrous metal.

The condensation plate 10 includes a condensation plate cast body 12 made of ferrous metal (cast iron is preferred). As can be seen from the above figures Out, The condensing plate casting body 12 is generally in the shape of a parallelepiped, wherein the front side and the rear side are respectively represented by component symbols 14 and 16. It should be known that four condensation pipes 18 made of copper or copper alloy are casted on Condensing plate casting body 12. These condensing pipes 18 are indicated by dashed lines in Fig. 2. As can be seen from Fig. 3, each condensing pipe 18 has a straight line that is substantially parallel to the front side of the condensing plate. Section 20. The two ends of this straight section 20 are respectively curved corner sections 22 protruding outward on the rear side 16 of the condensing plate casting body 12 to connect each condensing pipe 18 to the cooling pipe of a blast furnace, for example. . The current condensation plate 10 can be easily manufactured by a casting method.注意 It should be noted that the current condenser plate 10 contains a condenser tube 18 made of copper or copper alloy. The condenser tube 18 can be cooled to prevent it from melting out. In fact, the melting temperature of molten cast iron is usually 1200 ° C to 1300 ° C, while the melting temperature of copper is about 1083 ° C. 10-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297g t) 512174 A7 _ ___B7___ 5. Description of the invention (1) (Please read the precautions on the back before filling this page) Therefore, the condensation plate The production of 10 is preferably performed in the following manner. A mold having a size of the condensing plate casting body is provided, and a condensing tube is arranged in the mold. The condenser tube is then connected to a temperature control line to control the temperature of the condenser tube by generating a fluid flowing through the condenser tube. Secondly, molten cast iron is injected into the mold, surrounding the condensing tube, and the molten cast iron is allowed to solidify in the mold. Subsequently, the condensation tube is separated from the temperature control line, and the obtained condensation plate is taken out of the mold. When liquid cast iron is injected into the mold, a cooling fluid such as water, oil, or a gaseous fluid may be appropriately circulated through the condensation pipes to prevent the condensation pipes from melting out. The above-mentioned temperature control pipes can also be used to heat the condenser pipes by generating heat flow through the condenser pipes. The result of heating the condensing pipes allows to avoid the occurrence of thermal shock, and is used to eliminate and / or remove the copper oxide layer formed on the condensing pipes. Another solution to avoid overheating during the casting process is to store materials with high heat capacity in these condensers before injecting molten metal into the mold. The material with high thermal energy mentioned above is, for example, corundum, quartz sand, or other similar substances. It is preferable that the temperature of the condenser tubes can be controlled to obtain a specific kind of bonding method between the condenser tubes made of copper or copper alloy and the condensing plate casting body. The first bonding method can be called "mechanical bonding", in which the condenser plate and the condenser tubes such as ghai are in close contact with each other, but the metals of these components themselves will not be mixed with each other. Copper and copper The ductility of the alloy allows this close contact between the condenser tube and the cast iron, and 11 paper sizes are applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) 512174 A7 ____ B7 V. Description of the invention (p) There is no cracking. Another available bonding method is called "metallurgical bonding". In this application example, the metal of the condenser tube and the metal of the condenser plate are connected to each other. This result indicates that The outer surface of the condenser tube has been melted away and a thin layer of an intermediate alloy made of two metals is also formed. When the condenser plate is installed in a metallurgical furnace, the cast iron and the condenser tubes are interposed between the condenser plate The metallurgical combination generated between them allows better heat transfer from the condensing plate casting body to the refrigerant circulating through the condensing tubes. In this embodiment, 'the condensing plate casting body can It is preferable to have a series of equally spaced parallel ribs 24 on the front side 14 to increase the heat exchange surface of the condensing plate casting body and thus improve the cooling efficiency of the condensing plate 10. The condensing plate according to the present invention has It has been proven to have a "cooling effect" that is two to three times better than traditional cast iron transverse plates with steel pipes. This "cooling effect" is obtained when the condensation plate 10 (especially the traditional transverse plate) is exposed to the same heat source At the same time, the hottest location point on the heated side of the condensation plate is measured. In another embodiment of the manufacturing method of the present invention, a condensation plate is manufactured in a two-stage manner. In the first stage, A first mold for casting a shaped condensing plate casting body is provided. The condensing pipes are arranged in the first mold, and then liquid iron metal is injected into the first mold 'and surrounds the condensing pipes. The liquid iron metal is allowed to solidify, and a preformed condensing plate cast body with a cast-completed condenser tube is taken out of the first mold. Due to the amount of cast iron in the first stage Bietang condensing plate is in 12 paper sizes, applicable to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page)
