Description

Technical Field

[0001] The utility model relates to an intelligent stainless steel pipe annealing and solid melting furnace. Background Art

[0002] In the prior art, after the steel pipe is annealed in an intelligent stainless steel pipe annealing and solid-melting furnace, there are generally two cooling methods, one is to place it in a cooling pool for immersion cooling, and the other is to spray cooling under a spray mechanism arranged at the outlet end of the annealing and solid-melting furnace; the above two methods both have certain shortcomings, specifically: during the immersion cooling process in the cooling pool, whether it is the transfer process or the immersion process of the steel pipe, it is difficult to avoid friction and collision between the steel pipes, resulting in bending and deformation of the steel pipe, and it is also necessary to straighten it later; while spray cooling is performed at the outlet end of the annealing and solid-melting furnace, because the spraying often only has a water curtain spraying downward, the cooling of the steel pipe is not thorough enough, and it needs to be placed for a long time for natural cooling later. In addition, this cooling method will cause the sprayed surface of the steel pipe to cool down quickly, while the temperature of the surface that is not sprayed is still high. This drastic temperature difference may also cause changes in the quality of the steel pipe. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide an intelligent stainless steel pipe annealing and solid melting furnace, which is equipped with an efficient cooling spray mechanism and can prevent the steel pipe from bending and deforming during the cooling process.

[0004] The technical solution of the utility model is: an intelligent stainless steel pipe annealing and solid-melting furnace, comprising a main body and a cooling spray mechanism, the cooling spray mechanism comprising a spray channel with open ends, a plurality of spray components are arranged in the spray channel, the spray heads in each group of spray components are arranged in a circular array in the spray channel, a steel pipe transmission mechanism is also provided at the lower end of the spray channel, the steel pipe transmission mechanism comprises a plurality of transmission rollers and a driving mechanism, the annealed steel pipe is mounted on the transmission roller and passes through the spray channel at a uniform speed, and the spray heads of each spray component spray water simultaneously to form a circular water curtain to cool the periphery of the passing steel pipe.

[0005] Furthermore, the driving mechanism includes a driving motor and a transmission chain, one end of each of the driving rollers is rotatably connected to a side wall of the spray channel, the other end of each of the driving rollers passes through the other side wall of the spray channel and is rotatably connected to a roller seat, the driving motor is connected to one of the driving rollers, and the transmission chain is connected between one end of each driving roller passing through the spray channel.

[0006] Furthermore, each of the spraying components and the corresponding transmission rollers are staggered.

[0007] Furthermore, the spray channel is composed of a bottom plate and a cover body arranged on the bottom plate, and the cross-section of the cover body is in an inverted "U" shape.

[0008] Furthermore, the lower end of the cover body is provided with a plurality of openings.

[0009] Furthermore, a water retaining plate is provided on the bottom plates on both sides of the cover body, and a drainage groove is formed on the bottom plate between the two water retaining plates.

[0013] Furthermore, a mechanical arm is provided above the discharge channel for transferring the cooled steel pipe from the steel pipe transmission mechanism to the discharge channel.

[0014] The beneficial effects of the utility model are as follows: when the steel pipe passes through the spray channel, it is cooled by the circular water curtain sprayed by multiple groups of spray mechanisms. On the one hand, the spraying method is relatively gentle. On the other hand, since the water pressure on the periphery of the steel pipe is relatively uniform when passing through the water curtain, the steel pipe will not bend or deform during the spray cooling process. Moreover, the cooling of the steel pipe by multiple water curtains can effectively speed up the cooling speed of the steel pipe, achieve a rapid cooling effect, and ensure the final quality of the steel pipe.
