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.

Cast iron plate It is specially designed for the leveling of large equipment. It has the characteristics of reasonable design, stable structure, high precision and wear resistance. It can realize the flat stitching of 3000mm-6000mm. The product is made by scraping or grinding. Processing, tool shop, machine (inspection) repair shop, large equipment base, measuring room and precision machining inspection, measurement and grinding, and can accurately measure, check the workpiece flatness, flatness and angle tolerance value The

Crossed platform : Mainly used for a variety of parts of the flat crossed and three-dimensional crossed, the plate itself is a flat benchmark, the workpiece in its work surface can be achieved with high precision, fast efficiency and so on.

Crossed platform Manufacturing and acceptance standards: flat manufacturing according to national standards GB / T20428-2006, acceptance according to JJG117-2005 standards; other requirements according to the corresponding national standards and industry standards (tender documents should be clearly stated in the use of standards, such as the configuration Flattened horn).

Cast iron platform technical requirements:

1, the platform must be subject to two back stress stress aging treatment, to prevent the deformation of stress memory distortion and the future use of the platform into the phenomenon of cracks in the occurrence of the elimination of casting stress, the purpose of rough stress, stress relief of 90%

2, the end of the working face after the acute blunt;

3, the casting surface to be processed without external force, polished, the inner surface are required to paint anti-rust paint;

4, flat face can not seriously affect the appearance and performance of sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects.

3, the accuracy grade 0 ~ 3 flat face, the diameter of less than 15mm of the sand holes allow the same material blockage, the hardness should be less than the hardness of the same material around the work surface 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 face, 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.
