Cast iron plate called cast iron platform, cast iron platform uses: suitable for a variety of inspection, precision measurement reference plane, the dimensional accuracy of machine tools for measuring reference, check the shape and position of parts or bias, and make precision crossed. In the machinery is also lacking basic tools can not. Cast iron platform material: material is HT200-250 high-strength cast iron face hardness of HB160-210. After two treatment (artificial annealing 700 degrees or 600 degrees ---- 2 --- 3 years natural aging), so accuracy and stability of the product, good wear resistance. Cast iron platform accuracy: according to the national standard verification procedures, namely 0,1,2,3 level four levels. Surface quality flatbed / platform: cast iron platform Specifications: 200mm × 200mm-2000mm × 4000mm (special specifications can be produced according to the demand side or two sides agreed to drawing production and processing) iron platform inspection standards: with the coloring method test. 0 a flat platform at least 25 points in each side of 25 mm square range. 2 flat platform at least 20 points in each side of 25 mm square range. 3 flat platform less than 12 points in each side of 25 mm square range. Iron platform work surface should not have the appearance of defects rust, scratches, bumps and other effects used. Work surface should not have sand holes, pores, cracks, slag and casting defects such as shrinkage. All kinds of casting sand surface should be clear and smooth surface, painted solid. Each should repair blunt edge. Iron accuracy level platform below the work surface "00" level platform for the clearance hole diameter of less than 15mm from the same material allows the blockage, the hardness should be lower than the hardness of the surrounding material. The site of blockage in the work surface should be no more than four, their mutual distance between not less than 80mm. Cast iron platform reason for damage and preventive measures for the foundry industry, cast iron platform damage occurs phenomenon is relatively common, but the consequences of different degrees of loss is not the same, if the damage caused by cast iron platform integrity iron . ? Then what reasons caused by it first in injury cast iron platform in the box, when handling or cleaning up inadvertently caused the situation; second is the right platform for the clean-up of cast iron or cast riser direction take caliber is too large, resulting in lost meat with meat or defect. So how to prevent one, carefully follow the process operation;? 2, note that when the cleanup process method. Small cast iron platform generally used resin sand, one is for the convenience of sand, there are the following reasons: 1, resin sand stiffness, high early strength pouring sand expansion which conditional use graphite cast iron solidification process, effectively eliminate shrinkage, shrinkage defects, achieve less riser gray iron, ductile iron, non-riser casting. 2, the real production of polystyrene foam casting pattern applications furosemide feeding Resin Sand modeling. When the liquid metal poured into the mold, foam look quickly at a high temperature gasification of liquid metal effect, burn and disappear, replaced the liquid metal foam originally occupied the position, cooled and solidified into the same shape and look like real castings. Ming Wang measuring supply cast iron plate, T-shaped slot platform, welding platform, crossed the platform, floor boring machine table, the assembly platform. . . . . . Hotline 0317-8326905, precision cross River Zone major iron castings: according to national standards verification procedures were 00,0,1,2,3 and fine planing six levels.
