[Industrial Field of Application] The present invention relates to an apparatus for continuously annealing beryllium steel alloy materials such as plates and strips. [0002] [Prior Art] An apparatus for continuously annealing plate-shaped or strip-shaped metal materials is one that cools the metal material by continuously passing the heat-treated metal material through cooling water in a water tank. It has been known. However, with this cooling method, some of the water vapor generated when cooling the high-temperature metal material enters the annealing furnace, disturbing the atmosphere inside the furnace, and forming a strong oxide film on the surface of the metal material. , which was inconvenient. (0003) In order to solve this problem, the present applicant proposed a new annealing furnace as shown in FIG. After the metal material 1 to be heat-treated in the shape is heat-treated in the furnace body 2, it is cooled in the cooling chamber 3 and further transported to the outside. Between the furnace body 2 and the cooling chamber 3, A partition wall 4 is provided that is open only in the part through which the metal material 1 passes.The metal material 1 transported into the cooling chamber 3 is cooled by spraying from a cooling spray nozzle 5 provided at the upper part of the cooling chamber 3. Cooled by water. [00041 A steam discharge lower is provided at the upper part of the downstream side of the cooling chamber 3, and the steam generated during cooling is discharged from the steam discharge lower to the outside of the cooling chamber 3. Cooling water after cooling is collected from the cooling water recovery port 8 provided at the lower downstream side of the cooling chamber 3 and stored in the cooling waste water tank 9. At the gas seal 6 at the downstream end of the cooling chamber 3, a plate is sandwiched between packing or felt. A gas seal is performed in such a way that the
Intrusion of water vapor into the annealing furnace main body 2 can be effectively prevented. [0005] However, when the present inventor conducted further investigation, it became clear that problems still remained. That is, in gas sealing, the gas sealing is performed by sandwiching the plate between the gaskets and the felts 1 to 3, which causes damage to the stripes and lines of the plate-passing material. In addition, by passing the metal material 1 through the gas seal 6 for a long time, the packing and felt wear out and create gaps, which loses the sealing effect and allows atmospheric oxygen to enter the annealing furnace, causing the metal material 1 to oxidize. , change color. Furthermore, it is time-consuming to replace worn packings and felts 1, and the packings and felts are easily eroded by water vapor. Additionally, if the heat treatment conditions (temperature, threading speed) of the wire or strip suddenly change, cooling by the spray nozzle 5 may become temporarily insufficient, which may damage the felt or packing. there were.

[Embodiment] FIG. 1 is a schematic diagram showing a continuous annealing apparatus according to an embodiment of the present invention. The continuous annealing furnace main body 22 is provided with a gas supply port 32 for supplying the furnace atmosphere gas,
A cooling chamber 23 is provided in the conveying direction (downstream side) of the beryllium copper alloy material 21 in the furnace body 22, and the cooling chamber 23 and the furnace body 22
and is separated by a partition wall 34. This partition wall has a passage hole 37 through which the beryllium copper alloy material 21 passes.
A cover 24 whose diameter gradually decreases toward the downstream side around this passage port 37 is attached to the partition wall 34. Further, a spray nozzle 25 is disposed downstream of the cover 24, and the alloy material 211\ and cooling water are jetted from the spray nozzle 25 to cool the alloy material 21 after the heat treatment. The cooling water used for cooling is collected from the cooling water recovery port 35 and stored in the cooling waste water tank 29. Furthermore, a cover 30 that narrows toward the conveying direction of the alloy material 21 is attached to the downstream side of the spray nozzle 25. The water vapor generated when cooling the alloy material 21 is discharged from a water vapor outlet 27, and the discharger is controlled by a valve 31. [0009] A gas seal water tank 26 is installed downstream of the cooling chamber 23, and stored water 36 is stored therein. Then, the alloy material 21 cooled in the cooling chamber is once carried into the stored water 36, and then rolled out of the stored water 36, and then drained by the draining blower 28,
It is wound around a coil 33. [0010] First of all, the gas seal method is important in the annealing apparatus of this embodiment. That is, in order to prevent oxidation of beryllium steel alloy, which is easily susceptible to oxidation, in an annealing furnace,
Nitrogen, hydrogen, carbon dioxide,
Atmosphere gas such as argon is passed through to prevent oxidation of the material. At this time, in order to prevent oxygen in the outside air from flowing into the furnace, the pressure inside the furnace is made higher than the pressure of the outside air. For this reason, the method of sealing with the outside air is important. [0011] In this regard, in this embodiment, the alloy material is further passed through the stored water 36 in the gas seal water tank 26, thereby blocking ventilation between the inside of the furnace and the outside air. Therefore, since the metal material is not held down by packing or felt as shown in Figure 2, oxygen will not enter the furnace due to abrasion or deterioration of the gas seal.
Therefore, the oxygen concentration in the furnace must be kept low at all times, such as 5 PP.
It can be kept below M. This prevents discoloration of the alloy material due to oxidation, and furthermore, this discoloration of the alloy material increases the heat absorption of the alloy material in the annealing furnace, causing its temperature to rise too much and changing the material properties. It disappears. Furthermore, although it is necessary to perform cleaning with acid to remove the oxide film formed on the surface of the alloy material, the time required for cleaning with acid can also be shortened since the pickling performance at that time is improved. [0012] Of course, since the alloy material 21 is submerged in the stored water 36, maintenance of the gas seal part is easy, and the surface of the alloy material 21 is not damaged by the gas seal part. [0013] Furthermore, even if the heat treatment conditions are changed and the heat treatment temperature or line speed is increased and the spray nozzle 25 cannot keep up with the cooling of the alloy material 21, the alloy material 21 that has passed through the cooling chamber 23 will Because it enters the stored water 36, the material is completely cooled;
No hot material exits the annealing equipment. [0014] Furthermore, since the metal material carried out from the gas seal water tank 26 is immediately drained by the water draining blower 28, there is no possibility of oxidation due to water or air outside the water tank 26.
Can prevent discoloration. [0015] Note that the stored water 36 in the gas seal water tank 26 is constantly circulated and replaced with fresh water one after another to prevent the alloy material 21 from being contaminated by this stored water 36. Note that, as described above, the atmospheric gas is supplied from the gas supply port 32, and for example, nitrogen gas of 5 to 15 N+n3/hour is supplied. And the water vapor outlet 2 of the cooling chamber 23
Cooling chamber 2 is opened and closed by opening and closing valve 31 attached to 7.
By adjusting the pressure inside the annealing furnace body 22, the pressure inside the annealing furnace body 22 is always kept higher than the outside air pressure, and the water vapor inside the furnace body 2
Prevent backflow into 2. [0016] Furthermore, in order to anneal a metal material, it must be rapidly cooled at a certain cooling rate or higher. In this regard, in this embodiment, the cooling water jetted from the spray nozzle 25 performs rapid cooling. Here, if the steam generated by the evaporation of the cooling water flows back into the annealing furnace body 22, the alloy material 21 will change color as described above, so a cover 24 is provided on the partition wall 34 to cool the furnace body 22 from inside. The flow of gas into the chamber 23 is accelerated, thereby more completely preventing the backflow of water vapor. The water vapor generated here is discharged from the steam outlet 27 as described above, but the diameter of the outlet 27 is made small and the length of the discharge pipe is made long so that outside air does not flow in from this outlet. The steam is naturally exhausted by utilizing the pressure difference between the inside of the furnace and the outside air, or the steam is forcibly sucked through the exhaust port 27. [00171] Furthermore, in this embodiment, the alloy material 21 to be cooled in the cooling chamber 23 is configured to move downward in the conveying direction, thereby preventing the cooling water from flowing back into the furnace body 22. The number of spray nozzles 25 depends on the cooling capacity,
Can be changed depending on the cooling method. [0018] According to the present invention, the cooling chamber is gas-sealed by the water stored in the water tank provided on the delivery side of the beryllium steel alloy material in the cooling chamber, so the metal material can be sealed with packing or felt. Unlike the pressing gas seal method, oxygen does not enter the furnace due to abrasion or deterioration of the gas seal, and therefore the oxygen concentration within the annealing furnace can be maintained at a low concentration at all times. This can prevent discoloration of the alloy material in the annealing furnace due to oxidation, an increase in material temperature due to an increase in the heat absorption rate of the alloy material accompanying this discoloration, and the formation of an oxide film. At the same time, the gas seal part is easy to maintain and maintain, and the surface of the alloy material is not scratched. [0019] In addition, since the beryllium copper alloy material is once carried into the stored water, even if the heat treatment temperature or line speed in the annealing furnace body suddenly increases, the stored water can further completely cool the material. As a result, hot alloy material does not exit the annealing equipment. [00201] Furthermore, since the beryllium steel alloy material carried out from the stored water is drained, oxidation and discoloration of the alloy material due to water and air outside the water tank can be prevented. Furthermore, since the beryllium steel alloy material is cooled by the cooling water jetted from the spray nozzle, the finished shape of the beryllium copper alloy material can be made uniform.
