Description
Technical field
The cooling plate that the present invention relates to make the method for cooling plate and make in this way.
Background technology
Cooling plate is also referred to as " upright cold wall (staves) ", uses in blast furnace hundreds of years.Cooling plate is arranged on the inboard of furnace wall and has the internal coolant pipe that is connected with the chilled(cooling) water return (CWR) of blast furnace.The cold plate surface of facing high furnace interior can serve as a contrast uses refractory materials.The pipe connecting end of water coolant is arranged on the back side of cooling plate and draws the furnace wall with sealing means.The cooling channel of a plurality of cooling plates is connected in series, and is connected with the chilled(cooling) water return (CWR) of blast furnace by these pipe connecting ends of drawing the furnace wall.
Up to several years ago, the most cooling plates in blast furnace are cast iron cooling plates.Make this cast iron cooling plate and have diverse ways.According to first method, be used to cast the mold that cools off plate body and be provided with one or more cores that are used to form internal coolant ducts.Then, liquid cast is cast in the mold.The shortcoming of this method is: be difficult to remove the casting sand of cooling pipe, and/or the cooling pipe of cast iron is often got by moulding improper or firm inadequately.In order to overcome above-mentioned shortcoming, the someone proposes to be provided with preformed steel pipe in mold, and liquid cast is cast to around the steel pipe.But these cast iron cooling plates that have steel pipe can not be satisfactory.In fact, because carbon infiltrates steel pipe from cast iron, steel pipe becomes fragile and crackle may occur.
In order to replace the cast iron cooling plate, developed the cooling plate of copper and steel recently.The someone proposes to be used for the different production methods of copper " upright cold wall (staves) ".
At first, attempt to produce copper cooling plate, in mold, use core moulding internal coolant pipe by the casting of mold.But this method proves in practice and is not effectively because the cast copper plate body often has the gentle hole of cavity, have great negative impact this work-ing life to cooling plate.Be difficult to remove casting sand, and the frequent moulding of cooling pipe in the copper gets improper from cooling duct.
When GB-A-1571789 proposed to cast cooling plate in mold, the metal tube coil pipe made from preformed copper or high-quality steel replaced core.The coil pipe that forms spiral coolant duct is arranged in the mold, liquid copper cast in coil pipe around.This method also is proved to be in practice and is not effectively, because can not prevent cavity and pore in the copper coin body effectively, can not solve metal tube effectively and interfacial problem between the solidified copper in mold.
From DE-A-2907511, learn by forging or rolling copper coin manufacturing cooling plate.Main coolant pipe is the blind hole that gets out on rolled copper slab with mechanical drilling method.Blind hole seals by welding or welding plug.Then, get out the connecting hole that connects blind hole from the plate body back side.Therefore, be used for the pipe connecting end that coolant feed or refrigerant return and insert these connecting holes, and in position soldered or welding.Recently, also the someone propose to utilize identical method to produce cu cooling plate.These cooling plates can be avoided above-mentioned casting flaw.Particularly, can effectively eliminate plate interior cavity and pore.
The precast billet that the WO-98/30345 instruction is cast cooling plate by means of continuous casting mold, the clavate insert of wherein casting pipeline forms the pipeline of advancing along the continuous casting direction, and these pipelines constitute the main coolant pipe in the final cooling plate.By laterally forming two otch along casting direction, plate body is separated with the continuous casting precast billet, form two end faces corresponding to the distance of the desired length of cooling plate.At next production stage, the connecting hole that admission passage broadens pierces plate body perpendicular to the back side, and closes the end face aperture of casting pipeline.Therefore, connecting hole is inserted in the pipe connecting end, and welding or welding in position, as mentioned above.
The manufacture method of describing in DE-A 2907511 and WO 98/30345 can both be produced fine cooling plate body with copper or copper alloy.But, compare with cooling plate, or compare with the cooling plate of shape casting with monoblock casting cooling tube, have the defective of the quite high pressure-losses at transmission region from the pipe connecting end to the cooling channel with the final cooling plate of two kinds of methods productions.
Suggestion is inserted the otch of cooling plate body with drip molding among the WO 00/36154, has the flow losses of copper cooling plate of the cooling channel of monoblock casting or drilling with reduction, thereby forms the switching channel that heat-eliminating medium is had the optimal flow condition.But this method needs quite high labour intensity, and it has reflected higher production cost.
DE-A 3313998 discloses a kind of cooling plate that is used for the metallurgical furnace made by iron body.This cooling plate comprises by steel pipe and inserts the passage that the hole vertically run through main body formed, was used for cooling fluid.Steel pipe is by shrinkage fit in advance and be fixed in the iron body when temperature equilibrium.This method need be suitable for the large size shrinkage fit equipment of the costliness of iron body and steel pipe sizes.

The purpose of this invention is to provide simple, the reliable method of making cooling plate with suitable low pressure loss.Another object of the present invention provides the reliable cooling plate that has suitable low pressure loss, can make easily.These problems are used respectively according to the method for claim 1 with according to the cooling plate of claim 17 and are solved.
Method according to manufacturing cooling plate of the present invention may further comprise the steps: provide have the front, the back side and at least one run through the metal plate of the passage of metal plate below the front; The metal pipe that will have radius clearance inserts passage, makes two tube ends be projected into the passage outside, and realizes the press-fit of pipe in passage.According to an important feature, handle (metal-forming process) acquisition press-fit by metal plate being implemented metal forming.This metal forming is handled the contraction that causes channel cross-section.
Surprisingly, have been found that the press-fit of pipe in passage can handle by blank plate body (blankplate body) being implemented metal forming, obtain with simple, economic and reliable mode.
After pipe inserted, metal forming was handled and is made metal plate be deformed into the shape of expectation, is used to realize the press-fit of pipe in passage.Metal forming is handled the permanent mechanical deformation that comprises the sky metal plate, that is, and and viscous deformation.It for example is forging, the extruding or rolling of metal plate that possible metal forming is handled.Metal forming is handled the final state that plate body can be converted to cooling plate from dummy status.Do not realize the common unwanted additional processing of press-fit and do not get rid of.
Preferably, metal forming is handled along described at least one path partially ground and is implemented.The local execution reduces to form required power of press-fit or strength, thereby is convenient to mechanical treatment and reduces requirement to required equipment.For example, press-fit can by along described passage, for example produce permanent depression (depression) at the back side of metal plate and realize.Replacedly, whole metal plate can be handled through metal forming.
In the preferred embodiment of present method, the metal forming that metal plate is implemented is handled the recoverable deformation that forms pipe, to produce the pre-tensioned fit of pipe in passage.Because provide the scope of metal plate viscous deformation, that is, the press-fit of pipe recoverable deformation can be realized comprising in parameatal zone.The pre-tensioned fit of the pipe that is obtained in passage provides enhanced heat passage, can influence the physicals of pipe sharply.
