Cast iron slabs are used for scribing and grinding of parts, installation of equipment (shèbèi), etc. Cast iron slab Cast iron slab: It is mainly used to test the benchmark of workpiece error. The inspection slab/inspection platform plays a vital role in the mechanical manufacturing process.
It is the most basic benchmark tool for inspection of each workpiece before leaving the factory. Cast iron plates are widely used in industries such as machinery manufacturing, chemicals, hardware, aerospace, petroleum, automobile manufacturing, and instrumentation manufacturing. The die cast iron plate is the benchmark for measuring (cè liáng) to check the plane, parallelism, straightness and other geometric tolerances of machinery parts. It can also be used for scribing, riveting, welding and grinding technology of general parts and precision parts. Processing and measurement, etc., can also be used as a benchmark for machine tool inspection and measurement. Cast iron plates are widely used in industries such as machinery manufacturing, chemicals, hardware, aerospace, petroleum, automobile manufacturing, and instrumentation manufacturing. There are holes and T-shaped grooves on the job surface. The holes are mainly used to clean up some iron slag and welding waste during riveting. The T-shaped grooves are mainly used to fix the workpiece.
- Machinability and datum level of sand cast iron flat plates: National (guo) national standards (approved and issued: national (guo) national standardization authority) metrological verification procedures are implemented, respectively, four levels 1, 2, 3, and fine planing. In mechanical production (Produce), in order to stabilize the size of the casting, the casting is often placed at room temperature for a long time before cutting. This measure is also referred to as aging. But this kind of aging is not a metal heat treatment (processing) process. In the production of cast iron slabs, in order to eliminate the changes in the size and shape of the cast iron slabs during long-term use, the platform is often reheated to 100-150 degrees Celsius (°C) after low temperature tempering before finishing for a fixed time (yi) , Through this aging treatment to stabilize the quality of the platform (Mass). Therefore, there is extensive development in industrial development. Purchasing cast iron plates one (yi) fixed selection (Select) aging treatment. Advantages of cast iron slab aging: reduce (reduce) the brittleness of the slab, (make the slab more tough) eliminate or reduce internal stress, after the slab is quenched (cuì huǒ), there will be great internal stress and brittleness, if not tempered in time, the slab will often occur Deformation or even cracking (kāi liè). The cast iron slab has been manually annealed twice and has the characteristics of wear resistance, _, corrosion resistance (interpretation: refers to decay, disappearance, erosion, etc.). And has good castability and machinability.
- The hardness of the cast iron flat high-strength cast iron HT200-300 working surface is HB170-240.
- Cast iron flat plate/platform specifications (specifications): 1000x1000—3000x6000, (special specifications are produced according to the buyer's drawings).
- Structure (Structure): double enclosure type, single enclosure type, box type.
- Cast iron plate/weight deviation: In the production process (process), the cast iron platform will produce a deviation of the theoretical weight. According to the national (guo) standards, the weight error should generally not be 5% of the excess weight, otherwise it will affect the cast iron platform use.
- Engineering engineers can also design reasonable drawings according to your load-bearing and precision (precision accuracy) requirements to improve the performance of cast iron plates (xìng néng).
The service life of the cast iron plate itself can reach 50-100 years. Use a spirit level to adjust to the level so that the fulcrums are evenly distributed (jūn yún) on each fulcrum. Use caution to prevent collisions. Wipe it up after use, apply anhydrous acidity anti-rust oil, cover with moisture-proof paper, and store in a clean and dry place. After the flat panel is installed and debugged, wipe the working surface clean, and use it under the condition that there is no problem, so that the flat panel accuracy can be improved.
