March 11，Ningneng Polysilicon Project Base，The distillation column weighing 295 tons was successfully lifted.。On the day of hoisting，SCC19800TMAt 126mSlowly lift the upper section of the distillation tower under the working condition of the light super-lift main arm，With the cooperation of the auxiliary crane，Transition of tower from horizontal to vertical state，Until fully erected。Be methodical，Calm and orderly，The equipment was successfully closed at an altitude of 50 meters.。

Guo Kequan, technical director of Sinochem Second Construction Group Large Machinery Construction Co., Ltd., introduced.：“Ningneng polysilicon project is the largest single polysilicon project in China.，The total investment is 150 billion，The weight of the rectification device is also larger than that of the equipment in the same industry in China.，The overall weight is more than 500 tons.。”

With the perfect ending of the first distillation tower hoisting，The remaining 19 distillation towers of Ningneng Polysilicon Project will also complete the overall shipment work one after another.，When the project is finally completed and put into production，This polysilicon production line will produce 400000 tons of high-purity silicon annually.，Estimated annual output value of 90 billion yuan。

Zhou Bing, safety director of Sinochem Second Construction Group Large Machinery Construction Co., Ltd., said.：“I have always had an industrial dream.，Our petrifaction、Chemical Industry，Our manufacturing industry，Without these industries to support the country.，It is very difficult to support such a big country.。The development of new energy in recent years，We have achieved a lot of corner overtaking.。”

From 100 tons of small-scale production，It has developed into a large-scale mature production stage of more than 10000 tons.，Monopolize technology from abroad、Market、Scarcity of raw materials due to price，To seize the technological highland.，China has become the world's largest producer of polysilicon.。

Secretary of the Party Branch of Sinochem Second Construction Group Large Machinery Construction Co., Ltd.、Executive Director Liu Weiling said.：“ This year marks the 70th anniversary of the founding of China Chemistry.，It is also the 70th anniversary of the founding of Sinochem II.。It is hoped that Chinese chemistry will ride on the east wind of the country.，It can enable chemical manufacturing to achieve better capabilities.，Make a greater contribution。”

Bi Jiawei, deputy general manager of Sinochem Second Construction Group Co., Ltd.：“With the national two-carbon strategy,，Through the development of the polysilicon industry in the last two decades,，Make up for the shortcomings of the traditional energy sector，Strategic development of the country as a whole、Energy security is very important.。”

With the rapid development of photovoltaic new energy industry,，Chinese Builders Break Barriers with Wisdom and Innovation，Establish a leading position in the industry with high-quality products，It has achieved a new upgrade of China's energy development.。
