The pyrotechnic platform/pyrotechnic flat plate is manufactured according to the JB/T7974-1999 standard, and the product is made of ribbed plate and box type. The working surface can be rectangular, square or circular, and the materials are HT200-300, QT400-600, and ZG15-45. The working surface of the pyrotechnic platform/pyrotechnic flat plate adopts scraping and grinding technology, and can process V-shaped, T-shaped, U-shaped grooves, dovetail grooves, round holes, long holes, etc. on the working surface. A flat plate is a flat reference measuring tool used for workpiece detection or marking. Install and adjust the pyrotechnic platform/pyrotechnic flat plate to a horizontal plate, and evenly distribute the load on each support point. The ambient temperature is (20 ± 5) ℃. Avoid vibration during use. The pyrotechnic platform/pyrotechnic flat panel must have a flat appearance, accurate dimensions, no internal defects, sufficient strength and stiffness to withstand the impact force of pyrotechnic hammers, and meet the needs of pyrotechnic production.

　　Description of parameters for pyrotechnic platform/pyrotechnic tablet

　　1) Specification of pyrotechnic platform: 100 * 100-3000 * 6000mm, (special specifications can be made according to the drawings as needed)

　　2) Purpose of pyrotechnic platform: It is a reference plane suitable for various inspection work and precision measurement. It is used for machine tool mechanical inspection and measurement reference, inspection, and to measure the dimensional accuracy or behavioral deviation of precision parts, and to make precision marking. It is also an indispensable basic tool in mechanical manufacturing

　　3) The material of the pyrotechnic platform is HT200-300, QT400-600, ZG15-45. The hardness of the working surface is HB170-240. The casting has undergone two treatments (manual annealing at 600 ° -700 ° and natural aging for 2-8 years), resulting in stable accuracy and good wear resistance of the product.

　　4) Execution standard: manufactured according to JB/T7974-1999 standard. Precision shall be executed according to the national standard metrological verification regulation JJG117-91
