Material: cast iron plate using HT200-300 casting, material ingredients ingredients and ingredients according to the following criteria (%): carbon: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, phosphorus < 0.3. Hardness> 180, the second tempering treatment.

1, tooling platform (tooling plate) specifications: 1000 × 1000-4000 × 8000 (special specifications can be set according to the demand-side drawings.)

2, tooling platform (tooling plate) materials and treatment : The material is high strength cast iron HT200-300, face hardness HB170-240, after two manual processing (artificial annealing 600 degrees -700 degrees)

3, tooling platform (tooling plate)According to the national standard metrological verification procedures, respectively, 2, 3 two levels.For large equipment based flat (platform), rational design, high precision, wear characteristics.

4, tooling platform (tooling plate)Work surface should not have rust, scratches, bumps and other effects of the use of the appearance of defects.

5, tooling platform (tooling plate) work surface should not have sand holes, pores, cracks, slag and shrinkage and other casting defects. The casting surface should be completely removed sand, and the surface smooth, strong paint, the tax should be Obese.

6, in the tooling platform (tooling plate)On the opposite sides of the surface, there should be installed handle or hoisting position settings, threaded holes or cylindrical holes. Riveting platform to set the hoisting position should be considered to minimize the deformation caused by lifting.

7, tooling platform (tooling plate)Should be treated with stability and demagnetization.

8, tooling platform (tooling plate)The hardness of the face should be between HB170-220 or 187-255.

9, tooling platform (tooling flat)The main test items A, material and surface hardness B, shape and position tolerance, including the nominal size, vertical tolerance C, appearance D flatness E, contact spots F plane fluctuations G, H, surface roughness.
