The first domestic largest thermal power unit core component Dalian casting

Recently, Dalian Heavy Industry·Qingzhong Group Casting Steel Co., Ltd. successfully produced the core components for a 1000 MW high-efficiency supercritical power unit — the high-pressure and medium-pressure inner cylinders. This groundbreaking achievement marks the development of a domestically-produced, independently patented product that has put an end to China's long-standing reliance on imported technology. The city now stands as a leader in the national thermal processing industry, showcasing its growing technical capabilities and industrial strength. High-efficiency supercritical units, also known as high-parameter supercritical units, operate with main steam pressure ranging from 25 to 35 MPa and main steam and reheat steam temperatures exceeding 580°C. These advanced systems require highly precise and durable castings, often weighing over 100 tons. Before this breakthrough, no Chinese manufacturer had the capability to produce such high-quality components. Now, with this successful production, China is taking a significant step forward in mastering cutting-edge power generation technology, enhancing both its energy security and industrial competitiveness.

Sludge Drying Equipment Series

The Sludge Drying Equipment Series is a range of advanced and efficient machines designed to dry sludge to a solid form. These machines are ideal for use in wastewater treatment plants, oil refineries, chemical plants, and other industrial applications where sludge is produced as a byproduct.


The Sludge Drying Equipment Series is designed to handle large volumes of sludge and can process it quickly and efficiently. The machines use a combination of heat and air to dry the sludge, which is then collected in a solid form that can be easily transported and disposed of.


One of the key benefits of the Sludge Drying Equipment Series is its energy efficiency. The machines use a range of advanced technologies to minimize energy consumption and reduce operating costs. This makes them an ideal choice for businesses looking to reduce their environmental impact and lower their energy bills.


Another benefit of the Sludge Drying Equipment Series is its ease of use. The machines are designed to be simple and intuitive to operate, with minimal maintenance requirements. This means that businesses can easily integrate them into their existing operations without the need for extensive training or additional staff.


Overall, the Sludge Drying Equipment Series is an essential tool for businesses that produce large volumes of sludge. With its advanced technology, energy efficiency, and ease of use, it offers a cost-effective and sustainable solution for drying sludge and reducing environmental impact.
