Description

  The present invention provides a high yield and high yield of a powder clad plate produced by press-bonding powder to the surface of the plate to form a pressure-bonded material, and subsequently heating and cooling the pressure-bonded material to fuse the powder to the plate. The present invention relates to a method and equipment for producing a powder clad plate.

  In recent years, for example, a powder clad plate having a brazing material layer has been manufactured by integrating a metal powder mainly composed of nickel or the like on both sides or one side of a metal plate such as stainless steel or heat-resistant alloy. When manufacturing such a powder clad plate, it has been proposed to use equipment as shown in FIG.

  The powder clad plate manufacturing facility shown in FIG. 13 includes a rewinder 3 that unwinds a coil 2 around which a base plate 1 is wound, and a plate that is unwound from the rewinder 3. The powder rolling machine 4 that draws 1 and presses the metal powder (powder) onto the surface of the plate 1 to send out the pressure bonding material 5a, and the pressure bonding material 5a from the powder rolling machine 4 is heated in a heating furnace 6 to melt the powder. Next, the heating and cooling device 14 for forming the powder clad plate 5 by cooling the pressure-bonding material 5a to which the powder has been fused and the powder is fused by the cooler 7, and the powder clad plate 5 formed by the heating and cooling device 14 are required. A rolling mill or pinch roll 8 that performs rolling in response, and a winder 10 that winds the powder clad plate 5 that has passed through the rolling mill or pinch roll 8 around a powder clad coil 9 are provided.

  The powder rolling machine 4 includes a pair of rolls 11 arranged to face each other and rotationally driven, and a powder supply device 12 for supplying powder onto each roll 11, and from above between the pair of rotationally driven rolls 11. While the plate 1 is introduced downward, the powder supply device 12 supplies the powder onto each roll 11, thereby pressing the powder onto both surfaces of the plate 1 to form the pressure-bonding material 5 a. . Reference numerals 13a and 13b denote direction changing rolls that also serve as bridle rolls, and guide the plate 1 fed in the horizontal direction vertically to the powder rolling mill 4.

  The heating furnace 6 is usually provided with a metal box (not shown) whose cross section is closed in the longitudinal direction of the line, and a muffle furnace having an electric heater on the outside is used. The electric heater is inactive inside the heating furnace 6. The powder clad plate 5 is formed by fusing the powder to the plate 1 by raising the gas ambient temperature and heating to a temperature at which the powder of the pressure-bonding material 5a is melted by radiant heat. The cooler 7 includes a method of rapidly cooling the powder clad plate 5 by water cooling in addition to a method of cooling the powder clad plate 5 with an inert cooling gas and a method of cooling with the cooling gas.

  In order to manufacture the powder clad plate 5 by the powder clad plate manufacturing facility, the tip of the plate 1 unwound from the unwinder 3 is wound around the winder 10 through the powder rolling machine 4 and the heating / cooling device 14 and heated and cooled. After the heating furnace 6 and the cooler 7 of the apparatus 14 are operated, the powder rolling machine 4 is operated simultaneously with the start of winding by the winder 10. The powder rolling machine 4 draws the plate 1 at a constant speed, and supplies powder onto each roll 11 by the powder supply device 12 so that the powder is pressed on one or both sides of the plate 1 to send out the pressure-bonding material 5a. Since the pressure-bonding material 5a manufactured by the powder rolling machine 4 is only pressure-bonded by the pressure of the roll 11, when the processing such as cutting and bending the pressure-bonding material 5a as it is, the powder is removed from the plate 1. May fall off and may become unusable as a brazing material.

  For this reason, the pressure bonding material 5 a is introduced into the heating furnace 6 constituting the heating / cooling device 14 and heated to melt the powder and fuse it to the plate 1. At this time, the powder is fused to the plate 1 by melting the surface of the particle or a part of the powder (with a liquid phase). Subsequently, the pressure-bonding material 5a is introduced into the cooler 7 and cooled to solidify the molten particles, whereby the powder clad plate 5 is formed. The powder clad plate 5 derived from the heating / cooling device 14 is wound into a winder 10 through a rolling mill or a pinch roll 8 and wound at a constant winding speed to form a powder clad coil 9.

For example, Patent Document 1 shows a general technical level related to the powder clad plate manufacturing equipment as described above.
JP 2005-186127 A

  As shown in FIG. 13, in order to continuously manufacture the powder clad plate 5 by introducing the pressure-bonding material 5a and heating it to the melting temperature of the powder, followed by cooling, from the heating furnace 6 and the cooler 7 It is necessary to equip the long heating / cooling device 14. For example, in the testing machine implemented by the present inventors, the length of the heating / cooling device 14 was 20 meters even when the cooler 7 cooled by water cooling was used in addition to the cooling by the cooling gas.

  For this reason, when starting the manufacture of the powder clad plate 5 by winding the tip of the plate 1 unwound from the unwinder 3 around the winder 10, the plate 1 between the powder rolling machine 4 and the winder 10 is applied. Since the powder is not yet pressure-bonded, the plate 1 between the powder rolling machine 4 and the winder 10 cannot be used as the powder clad plate 5 and is wasted, so that the yield is poor. It was.

  Further, conventionally, when the unwinding of the coil 2 by the unwinding machine 3 is finished, the powder clad plate 5 is formed up to the rear end of the plate 1 and is wound up by the winder 10 for the next work. Since a batch system is employed in which a new coil 2 is set in the rewinding machine 3 and the same operation as described above is performed again, each time the new coil 2 is unwound and the powder clad plate 5 is manufactured, Similarly, there is a problem that the plate 1 between the powder rolling machine 4 and the winder 10 is wasted and the yield is lowered, and the tip of the plate 1 unwound from the new coil 2 is used as the powder rolling machine 4. In addition, since the work to be wound around the winder 10 through the heating / cooling device 14 is required each time, the work is complicated and takes time, and thus the productivity is further lowered.
