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, HT250 electric car motor test stand / cast iron plate must be two back stress stress aging treatment to prevent stress memory deformation distortion and the platform used in the future into the phenomenon of cracks in the occurrence of the elimination of casting stress, the purpose of rough stress , More than 90% stress relief;

2, HT250 electric car motor test bed / cast iron plate face finished processing sharp angle blunt;

3, HT250 electric car motor test stand / cast iron plate castings outside the surface of non-processing to be greasy, polished, the inner surface are required to paint anti-rust paint;

4, HT250 electric car motor test stand / cast iron plate face may not seriously affect the appearance and performance of sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects.

5 precision grade 0 ~ 3 precision mechanical mechanical cast iron fitter platform / cast iron plate face, less than 15mm in diameter sand holes allow the same material blockage, the hardness should be less than the same material hardness. Blocked sand holes should not be more than 4. And the distance between the sand holes should be not less than 80mm.

6HT250 electric vehicle motor test stand / cast iron plate should be used high-quality fine gray cast iron or alloy cast iron and other materials, the face hardness should be 170 ~ 220HB.

7HT250 electric car motor test stand / cast iron plate face is usually applied to use scraping process.For scraping the three-stage flat surface, the surface roughness Ra of the maximum allowable value of 5чm.
