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 motor Rally Test Bench Technical Requirements:

1, Cast iron motor tension test stand It is necessary to go through twice the stress aging treatment to prevent the deformation of stress memory 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, stress relief of 90%

2, cast iron motor test stand The working face finished processing acute angle blunt;

3, cast iron motor test stand External force processing surface to be greasy, polished, the inner surface are required to paint anti-rust paint;

4, cast iron motor test stand The face must not seriously affect the appearance and performance of sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects.

5 cast iron motor test stand The sand holes with diameter less than 15mm are allowed to be plugged with the same material, and the hardness shall be less than the hardness of the same material. And the distance between the sand holes should not be less than 80mm.

6Cast iron motor test stand Should use high-quality fine gray cast iron or alloy cast iron and other materials, the face hardness should be 170 ~ 220HB.

7Cast iron motor test stand The surface roughness Ra is the maximum allowable value for a 3-grade flat face with scraping duration of 5 чm.

8Cast iron motor tension test stand The face should be painted with the scraping process should be carried out on the research test.The proportion of the contact area after the study shown in Table 3, or by 25mm × 25mm in the number of points of contact should not be greater than 5. If controversial, According to the contact area ratio for the assessment basis.

9Cast iron motor test stand On both sides, there shall be a threaded hole (or a cylindrical hole) for the installation of the handle or eyelet device and the position of the device shall be designed to minimize deformation due to handling.

10 if Cast iron motor tension test stand The working face shall be provided with screw holes (or grooves) whose position shall not be higher than the working face.
