Cast iron pyrotechnic plate

1、 Cast iron pyrotechnic platform (pyrotechnic platform) alias: pyrotechnic platform, pyrotechnic platform, cast iron pyrotechnic platform, cast iron pyrotechnic platform.
2、 Application of cast iron pyrotechnic platform: In the process of water and fire processing, it is used to carry and fix ship shell steel plates and steel parts with curved processing requirements. Generally used in the shipbuilding industry. The pyrotechnic platform tablet must have a flat appearance, accurate dimensions, no internal defects, sufficient strength and rigidity to withstand the impact force of pyrotechnic hammers, and meet the needs of pyrotechnic production.
3、 Cast iron pyrotechnic flat plate (pyrotechnic platform) material: high-quality high-strength gray cast iron HT250 or QT450, with a working face hardness of HB200-240. The casting has undergone two artificial annealing processes at 600 ℃ -700 ℃ or natural aging for 2-3 years, completely removing internal stress, with stable accuracy and good wear resistance.
4、 Cast iron pyrotechnic flat plate (pyrotechnic platform) specifications: 1000X2000-3000X4000 (mm) Special specifications can be manufactured according to user needs.
5、 Precision of cast iron pyrotechnic flat plate (pyrotechnic platform): According to the national standard metrological verification regulation JJG117-91, it is classified as level 3 and precision planing.
6、 Surface treatment of cast iron pyrotechnic flat plate (pyrotechnic platform): The working surface adopts scraping and grinding process, and is inspected by coloring method to ensure the accuracy of the plane. The working surface is generally flat, and circular holes are machined on the working surface.
7、 Processing of cast iron pyrotechnic flat plate (pyrotechnic platform) working face: The working face generally has circular holes, and the spacing between the circular holes can be determined by the customer.
