The Industrial Park has designed 2 projects and 1 R & D center, namely the comprehensive utilization project of 1.2 million tons/year carbon and waste heat, the 50,000 tons/year special resistance project, and the carbon and special resistance research and development center.

2015.11

The first phase of the project with an annual output of 300,000 tons of calcined coke has been completed and put into operation. The production line has the most advanced carbon production equipment and technological level in China. It took only 6 months and 20 days from the start of construction to the start of production. It is a new miracle in the carbon industry. It also fully reflects the "Yujia Speed" and the hard-working spirit of Yujia people, which has set a benchmark in the industry and made it a high-quality project in the carbon industry.
