The other day，China Quality Association announced the list of winners of the Quality Technology Award of China Quality Association in 2023.，Railway Construction Heavy Industry《Research and Application of Key Process and Quality Control Technology of Roadheader Green Remanufacturing》The project won the award of excellence。

It is understood that，China Quality Technology Award was established in 2005.，It is the only one in the field of quality technology in China that has passed the Ministry of Science and Technology.、Science and technology awards approved by the National Science and Technology Award Office，It is the highest award in the field of quality technology in China.。The award is evaluated annually.，The total number of awarded projects shall not exceed 30% of the total number of projects accepted in that year%。

Railway Construction Heavy Industry is the world's leading large-scale customization enterprise of underground engineering equipment and rail transit equipment.，Actively respond to the national strategy to develop green remanufacturing technology of roadheader。Aiming at the problem that the traditional roadheader products do not form a closed loop of the whole life cycle.，Innovate the product design process，The green product design for remanufacturing is completed.，Breakthrough precision repair、Surface lift、Hydraulic oil regeneration and other key processes，Development of welding process monitoring、Phase-controlled vibration detection and other quality control technologies，Close the whole life cycle chain of roadheader products，Realize the green remanufacturing of the roadheader、Reapply。

The project breaks through the technology of precision forming, repair, remanufacturing and quality control of large structural parts and automatic sandblasting of super-large structural parts.-Quality Control Technology of Environmental Protection Coating and Surface Improvement，The off-line treatment and in-service regeneration equipment for efficient oil purification of roadheader is developed.，Break through the rapid detection technology of oil purification quality。
