How to Make Independent Innovation In Foundry Enterprises

The outline of China's eleventh five year development plan points out that it is necessary to "improve the industrial technology level with independent innovation, strive to master core and key technologies, enhance the transformation ability of scientific and technological achievements, and improve the overall technical level of the industry". At present, the technological independent innovation of foundry industry mainly includes the following main areas:

1. Casting technology of large and key equipment parts: mainly including casting technology of large and extra large steel castings and ductile iron parts (such as turbine blade, upper ring, lower ring, rolling mill frame, nuclear waste tank, etc.); Casting technology of directionally solidified blades and single crystal blades of steam turbine and turbine engine; Production technology of aerospace aluminum alloy, magnesium alloy and titanium alloy large structural castings.

2. Light metal advanced casting and forming technology: mainly including die casting technology of complex automobile aluminum alloy castings (such as automobile engine cylinder block); Aluminum alloy semi-solid casting technology; Squeeze casting technology of aluminum alloy and aluminum matrix composites; Production technology of large thin wall aluminum alloy castings; Complete set of aluminum alloy precision sand casting technology; High performance magnesium alloy die casting technology (such as vacuum die casting, ultra-low speed die casting, etc.); Development of cast heat-resistant magnesium alloy materials; Anticorrosion technology of magnesium alloy castings.

3. High quality, efficient, energy-saving and environment-friendly casting technology: mainly including the development of energy-saving and environment-friendly casting equipment and auxiliary materials, such as smoke and dust removal of cupola; Develop low pollution, non pollution and normal temperature hardening sand mold and sand core binder; Recycling and comprehensive utilization technology of foundry waste; EPC technology and the development of complete sets of precision and efficient forming equipment, such as high-precision foam forming machine, bonding machine, intelligent vibration compaction device, and the integrated technology of "waste heat heat treatment, sand falling and sand regeneration" of aluminum alloy castings.

4.
