Description

Technical Field

[0001] This invention relates to the field of SNCrW (Silver Bright Steel Bar) production technology, and more particularly to an apparatus and method for producing SNCrW. Background Technology

[0002] Bright silver steel bars are high-precision steel products with special surface treatment. They are usually made from high-quality round steel and processed through peeling, polishing, cold drawing and other processes. Their surface is bright silver, smooth and clean, free of defects such as oxide scale and cracks. They have high dimensional accuracy and tolerances can be controlled within a small range. They have good mechanical and machinability and can be used directly without additional surface treatment. They are widely used in precision machinery, automotive parts, instruments and meters and other fields, which can reduce subsequent processing steps and improve production efficiency and product quality.

[0003] The production of SNCrW bright silver steel bars begins with a preheated steel billet to remove impurities and reach a suitable temperature. Next, an integrated rolling and forging device gradually breaks down carbides using a roll mill. The forging module then performs light forging to optimize the microstructure and prevent secondary carbide precipitation. Afterward, the qualified billet is transferred to a surface finishing device where defects are removed by a cutting tool, and the surface is polished with a polishing wheel while simultaneously cleaning debris. Finally, the finished product is inspected, and qualified billets are collected and maintained to complete the production process.

[0004] Because SNCrW steel contains a high proportion of Cr and W elements, the primary carbides in the as-cast structure are severely segregated. Conventional rolling is difficult to fully break them due to insufficient deformation, resulting in a high level of banded carbides, which affects high-temperature fatigue performance. Although forging can achieve large deformation, the temperature drops quickly at the corners of the billet in a single process, making it easy for secondary carbides to precipitate, and the core structure is unevenly refined.

[0005] Therefore, it is necessary to provide a production apparatus and method for bright silver steel bars (SNCrW) to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a production apparatus and method for bright silver steel bars (SNCrW), which solves the problems of SNCrW steel's performance being affected by the difficulty in crushing it during conventional rolling due to the high Cr and W primary carbide segregation in the as-cast state, and the existence of temperature drop and uneven microstructure when forged alone.

[0024] A method for using an apparatus for producing bright silver steel bars (SNCrW), the method comprising the following steps:

[0025] S1: First, heat the SNCrW steel billet to ensure that the billet reaches the appropriate rolling and forging temperature, remove the impurities and oxide layer attached to the surface, and start the three sets of rolling mills for rolling. Then, the initial forging integrated carbide crushing device is used in conjunction with the peeling structure adaptive surface dressing device. Check the status of the core components of the two devices. The three sets of rolling mills need to be confirmed to have no wear on the die, no damage on the surface of the arc forging head of the forging module, and the peeling cutter head of the surface dressing device needs to be sharp and without nicks, and the polishing wheel needs to be without deformation. Then, according to the specifications of the billet to be processed, preset the transmission speed linkage parameters of the rolling mills and the cutting pressure threshold of the surface dressing device to complete the device initialization preparation.

[0026] S2: The pre-treated billet is conveyed to the feed end of the rolling and forging integrated device. The billet first enters the three sets of gradually changing rolls. Under the action of the third set of diamond rolls, the spiral convex edges of the roll surface apply shear force to the surface of the billet, initially breaking the carbides accumulated on the surface. Then the billet enters the second set of elliptical rolls and the first set of circular rolls, further reducing the diameter while subjecting the core of the billet to radial pressure, causing microcracks to form in the carbide aggregates. When the billet moves to the end of the roll set, the forging hammer is started. The arc-shaped forging hammer performs high-frequency light pressure forging on the rolled billet. The hemispherical protrusions on its surface penetrate into the surface of the billet, breaking the incompletely disintegrated carbides and completing the optimization of the internal structure of the billet.

[0027] S3: After the rolling and forging process is completed, the peeling assembly, together with the peeling tool, adaptively adjusts the angle to trim the surface of the forged billet. After the surface trimming is completed, the finished SNCrW bright steel bar is subjected to quality inspection, including surface roughness, dimensional accuracy, ovality and internal flaw detection, to confirm that the finished product meets the quality standards for bright steel bars. Finally, the equipment on the production table is shut down, and the core components such as the roll group, forging hammer, peeling tool and so on are cleaned and maintained to remove residual metal debris and impurities from the surface, check the wear of the components and make records to prepare for the next production.

[0028] Compared with related technologies, the production apparatus and method for bright silver steel bars (SNCrW) provided by this invention have the following beneficial effects:

[0029] This invention provides a production apparatus and method for bright SNCrW steel bars. To improve the carbide breakage rate during the production of bright SNCrW steel bars, three sets of telescopic components are used between the mounting frames to install a circular first roll group, an elliptical second roll group, and a diamond-shaped third roll group, respectively. The telescopic components can adjust the spacing between two rolls in the first, second, and third roll groups to accommodate bright SNCrW steel bars of different diameters. A cleaning component is then installed on one side of the mounting frame near the first roll group to clean the surface of the bright SNCrW steel bars after rolling. Preliminary forging can then be performed using a forging hammer and forging table. This design significantly improves the carbide breakage rate, significantly reduces the level of banded carbides, meets the high-temperature fatigue performance requirements of SNCrW steel, and integrates the rolling and forging processes, improving production efficiency, reducing surface oxidation loss during billet transfer, and optimizing the performance of each stage of production.

10. A method of using a production apparatus for bright silver steel bars (SNCrW), characterized in that, The apparatus for producing bright SNCrW steel bars as described in any one of claims 1-9, wherein the apparatus for producing bright SNCrW steel bars requires a method of use, comprising the following steps: S1: First, heat the SNCrW steel billet to ensure that the billet reaches the appropriate rolling and forging temperature, remove the impurities and oxide layer attached to the surface, and start the three sets of rolling mills for rolling. Then, the initial forging integrated carbide crushing device is used in conjunction with the peeling structure adaptive surface dressing device. Check the status of the core components of the two devices. The three sets of rolling mills need to be confirmed to have no wear on the die, no damage on the surface of the arc forging head of the forging module, and the peeling cutter head of the surface dressing device needs to be sharp and without nicks, and the polishing wheel needs to be without deformation. Then, according to the specifications of the billet to be processed, preset the transmission speed linkage parameters of the rolling mills and the cutting pressure threshold of the surface dressing device to complete the device initialization preparation. S2: The pre-treated billet is conveyed to the feed end of the rolling and forging integrated device. The billet first enters the three sets of gradually changing rolls. Under the action of the third set of diamond rolls, the spiral convex edges of the roll surface apply shear force to the surface of the billet, initially breaking the carbides accumulated on the surface. Then the billet enters the second set of elliptical rolls and the first set of circular rolls, further reducing the diameter while subjecting the core of the billet to radial pressure, causing microcracks to form in the carbide aggregates. When the billet moves to the end of the roll set, the forging hammer is started. The arc-shaped forging hammer performs high-frequency light pressure forging on the rolled billet. The hemispherical protrusions on its surface penetrate into the surface of the billet, breaking the incompletely disintegrated carbides and completing the optimization of the internal structure of the billet. S3: After the rolling and forging process is completed, the peeling assembly, together with the peeling tool, adaptively adjusts the angle to trim the surface of the forged billet. After the surface trimming is completed, the finished SNCrW bright steel bar is subjected to quality inspection, including surface roughness, dimensional accuracy, ovality and internal flaw detection, to confirm that the finished product meets the quality standards for bright steel bars. Finally, the equipment on the production table is shut down, and the core components such as the roll group, forging hammer, peeling tool and so on are cleaned and maintained to remove residual metal debris and impurities from the surface, check the wear of the components and make records to prepare for the next production.
