Calibrated steel round https://ukrstarline.ua/ru/chernyj-metalloprokat/stalnoj-krug/stalnoj-krug-kalibrovannyj is a metal bar with a round cross-section. In the production process, it undergoes mechanical processing, the purpose of which is to achieve a smooth surface and high dimensional accuracy. This type of rolled products made of high-quality steel is manufactured according to GOST, presented by manufacturers in a wide range.
The production process of calibrated steel circles
Production consists of several stages, of which the most important is the process of cold drawing. At this stage, the steel billet is drawn through a matrix to reduce the diameter and improve mechanical properties.
Depending on the required characteristics and application, different grades of steel are used in the production of calibrated circles:
- structural carbon steel;
- high-carbon tool steel;
- alloyed tool steel.
Cold-rolled or cold-drawn technologies are used for the manufacture of calibrated circles. The process in both cases takes place at low temperature, thanks to which accurate surface dimensions without roughness are achieved. In cold-rolled technology, steel billets are rolled. Cold-drawn steel billets are drawn through a narrow hole to make cold-drawn steel calibrated circles. Both technologies ensure the manufacture of products with the same quality standards, corresponding to GOST.
Features and spheres of application of calibrated steel circle
Calibrated steel circle has unique features, thanks to which it is widely used in mechanical engineering, construction and everywhere where there are high requirements for accuracy and quality.
Its main features are:
- Precise dimensions. After special processing, the product has minimal deviations in diameter. This characteristic is ideal for the production of high precision parts.
- Smooth surface. The circle is subjected to calibration, as a result of which the surface roughness is reduced. As a result, the need for additional machining is minimized in the manufacture of parts, other products.
- Improved physical properties. Calibrated circles have increased strength, resistance to deformation.
Calibrated steel circles are available in diameters from 3 to 100 mm. Small diameters up to 20 mm are used for the production of small parts. Shafts, axles, massive parts are made of circles with a diameter of 20-60 mm. For structures with higher requirements for strength and rigidity, calibrated circles with a diameter of 60-100 mm are used.
The standard length of calibrated circles is from 3 to 6 m, but manufacturers can produce other lengths at the customer's request. The choice of specific sizes depends on the standards and requirements of the buyer.
Due to its qualities, calibrated steel circle is widely used in various industries, especially those where accuracy and reliability come first. It is used in the construction of machines, ships, machine tools. It is ideal for the production of measuring and cutting and tools, as it has a high-quality surface with precise dimensions.
How to choose a calibrated steel circle
On the correct selection of material depends on compliance with the technical requirements for the product manufactured from the circle and minimize production costs. Consider important factors to select the best calibrated steel wheel:
- Determine the required diameter and length. The choice depends on the dimensions of the future parts and the technical requirements of the project. Consider standard sizes for optimum purchasing.
- Select the steel grade. Consider the requirements for mechanical properties, corrosion resistance, and operating conditions.
- Consider accuracy and surface condition. For high-precision parts, select calibrated wheels with minimum tolerances and smooth surfaces.
- Check standards and certifications. Make sure that the wheel complies with GOST, has the necessary quality certificates.
- Take into account the specifics of the application. Determine in what field the circles will be used: construction, mechanical engineering, tool manufacturing or other. Different areas of application may require special properties of steel.
High requirements for mechanical performance and durability of products are satisfied by accurate dimensions, quality surface and a variety of metal grades of steel calibrated circles. This is a universal and high-precision material that is used in a wide variety of industries. The right choice of calibrated wheel, taking into account the diameter, length, steel grade and accuracy requirements, ensures the efficiency of production processes and high quality of the final product.
