Cast iron platform included

Material: cast iron plate with HT200-300 casting, material ingredients when the raw material content plus ingredients as follows (%): carbon content: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, 0.3. Hardness> 180, secondary tempering treatment.

Inspection platform installation and load-bearing: The maximum weight of the workpiece to test the user design; with adjustable horn or platform bracket to support the installation of load bearing uniform distribution; provide test platform detailed installation instructions, with installation drawings, including support points layout plan, Masonry support design details, foundation diagram. If you need a larger load-bearing platform, by my company's technical staff to provide you with the design and production.

Inspection platform Weekly inspection period: After the initial use of 2-3 months after installation, after the general 612 months

Cast iron platform technical requirements:

1, the platform must be twice after the stress stress aging treatment to prevent the deformation of the stress memory distortion and the future use of the platform in the occurrence of cracks in the phenomenon of elimination of casting stress, roughing the purpose of stress, stress relief of more than 90%

2, the face of processing at the end of sharp angle;

3, casting the external surface of the rough surface to be tired, polished, the inner surface are required to apply anti-rust paint;

4, flat face can not have a serious impact on the appearance and performance of sand holes, stomata, cracks, slag, shrink loose, scratches, bumps, rust and other defects.

3, the accuracy grade 0 ~ 3 flat working surface, the diameter of less than 15mm of sand holes allow the same material blockage, the hardness should be less than the hardness of the same material.Faceface blocked sand holes should not be more than 4 And the distance between the sand holes should not be less than 80mm.

4, the plate should be high-quality fine gray cast iron or alloy cast iron and other materials, the face hardness should be 170 ~ 220HB.

5, the flat face is usually applied to use scraping process.For scraping the three-stage flat working surface, the surface roughness Ra of the maximum allowable value of 5чm.

7, the flat face with the scraping process should be carried out on the color of the test. The proportion of contact area after the inquiry shown in Table 3, or 25mm × 25mm in the number of points of contact should not be greater than 5 points Controversial, according to the ratio of contact area for the assessment basis.

8, the plate relative to the two sides, there should be installed handle or ring device screw hole (or cylindrical hole), and the device location should be designed to minimize the deformation caused by handling.

9, if the flat working surface set screw hole (or groove), the site should not be higher than the face.
