For example, in an annealing treatment apparatus for processing high-temperature welding wire for thermal power generation, disclosed in application publication number CN215162911U, the points of the technical means are fixedly attached to a furnace body having a supply port and an intake hole, and an inner bottom surface of the furnace body. , a drive motor having a rotating block fixedly attached to the top surface thereof, and an annealing assembly provided on the upper side of the furnace body to prevent oxidation discoloration during annealing of the metal wire.

In the above application, a rotating block is provided, and when annealing the welding wire on the top surface of the rotating block, by pressing the provided pressing block downward, the pressing block is moved by the moving block to the second engaging column and the covering. Move the block downward and apply pressure to the second spring to push the inert gas inside the storage chamber into the exhaust pipe, and the inert gas enters the inside of the furnace body through the exhaust pipe and welds. It can protect the wire, prevent the temperature from being too high and cause oxidation discoloration during annealing of the welding wire, and achieve the effect of protecting the welding wire, but do not directly bring the welding wire to the specified temperature when heating the welding wire. Since the welding wire is heated and then cooled to room temperature, there is a large temperature difference between the welding wire temperature and the room temperature after heating, and the large temperature difference during the cooling process makes the welding wire easy to break and cannot be used reliably. Therefore, the market needs an annealing equipment for processing high temperature welding wire for thermal power generation, which can solve the conventional problems.

The purpose of the present invention is to directly heat the welding wire to a predetermined temperature and then cool it at room temperature, as submitted in the above background art, so that the temperature difference between the heated welding wire and the room temperature becomes large. To solve the problem that the welding wire is easily broken due to a large temperature difference during the cooling process and cannot be used reliably, an annealing device for processing high-temperature welding wire for thermal power generation is provided.

In order to achieve the above object, the present invention provides an annealing device for processing high-temperature welding wire for thermal power generation, including an annealing device, wherein the annealing device includes first heating devices for heating in stages. , a second heating device, a third heating device, and a fourth heating device are provided, and the heating temperature of the first heating device, the second heating device, the third heating device, and the fourth heating device gradually decreases in order, and the heating temperature of the second heating device, the third heating device, and the fourth heating device are gradually decreased. The present invention provides technical means for an annealing device for processing high-temperature welding wire for thermal power generation, in which the heating temperature of the heating device is the welding wire annealing heating temperature, and the heating temperature of the fourth heating device is 50°C.

1. In this invention, by providing a first heating device, a second heating device, a third heating device, and a fourth heating device, when a high-temperature welding wire for thermal power generation is annealed and heated, the first heating device can perform preheating. The second heating device performs annealing heating to heat the welding wire to the annealing temperature, and the heating temperature of the third heating device is lower than the heating temperature of the second heating device, and the heating temperature of the fourth heating device is lower than the heating temperature of the fourth heating device. The heating temperature of the fourth heating device is between 50°C and the heating temperature of the second heating device, which reduces the temperature drop rate of the welding wire and prevents the welding wire from suddenly dropping and breaking. Since the temperature is close to room temperature, it has the effect of shifting to room temperature, slowly lowering the temperature of the welding wire to a temperature close to room temperature and cooling it, improving the annealing quality and making it possible to use this annealing device more reliably.

2. In this invention, a plurality of conveyance rollers for conveying the welding wire are provided inside the annealing device, and since the pitch between the plurality of conveyance rollers is small, the welding wire is prevented from being caught between the conveyance rollers, By supporting the welding wire using a plurality of conveyance rollers, the welding wire can be stably conveyed and the stability of the conveyance work can be improved.
