AI Technical Summary

Benefits of technology

This new type of casting metal used for making engines can have better properties compared to existing ones due to its composition including specific elements like Iron (Fe), Silicon Carbide Copper) Phosphor bronze (Cuprous Magnesite). Additionally, this new engine also includes certain other components such as Boron Plasma Spray coating or Thermal sprayed coatings on their surface instead of just adding them themselves. Overall these improvements make it more durable over time while still providing high efficiency during use.

Problems solved by technology

This patented problem with existing gas compression systems has been caused by their use in harsh environments where they can be affected easily due to high temperatures or other factors like rusting. These issues have resulted from improper lubrication during operation that causes damage to components such as bearings used in these machines.

Embodiment Construction

[0023] In order to meet the requirements of boron-phosphorus alloy cast iron, it is required that the furnace charge must be pure, high-quality pig iron should be selected, impurities such as C, SI, Mn, P, S, B in raw materials must be controlled at the lowest level, and the content of impurity elements in scrap steel must be controlled at the lowest level . Its weight ratio per percentage is: C-3.19, SI-2.24, Mn-0.79, P-0.272, S-0.082, B-0.039, Fe-94.

[0024] Use 12T medium-frequency induction furnace to melt, heat the charge to 1500-1520°C, after testing, adjust the composition to 1450-1460°C, control the pouring temperature at 1350±10°C, and cast it into the air compressor cylinder block.

[0025] The invention is suitable for making cylinder blocks of air compressors.
