Cast iron plate material: high-strength cast iron HT200-300 face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years) using the precision and stability of the product, good wear resistance . Iron platform work surface should not have sand holes, pores, cracks, slag and casting defects such as shrinkage of cast iron plate platform design requirements generally based JB / T 7974-2000 design but also according to the actual needs of the iron plate technology requirements in national standards and enterprise standards and requirements of cast iron plates in cast iron plate, can design the technical requirements of the spirit of the cast iron plate at the lowest cost to achieve the best practice principles based on the needs of the cast iron plate made technical requirements. cast iron plate manufacturing GB/4986-85 standard platform, products made of reinforced plate and box-style, rectangular work, material HT200, working surface by scraping process, the working surface can add V-, T-, U- slots and holes, long holes and so on. Flat is flat baseline detection apparatus for workpiece or crossed. Installation should be raised to the level of the plate, the load were distributed in the pivot, the ambient temperature (20 ± 5 ℃) should be used to prevent vibration. Cast iron plate platform specifications: 100 × 100-2000 × 4000, (cast iron plate larger than this size can be assembled using or drawings made), use: for mechanical, engine power test, debug, and has good stability plane and toughness, surface with T-slots can be used to fix laboratory equipment.
