Zhongxin Chuangwei provides network time server equipment to Xingtai Machinery Roll Co., Ltd. of China Steel Group.

Recently, Xingtai Mechanical Roll Co., Ltd. of China Steel Group issued a requirement for a clock synchronization system. Beijing Zhongxin Chuang promptly collaborated to develop a detailed solution and recommended its independently developed and manufactured DNTS-94S-OGB model as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the time server project from Xingtai Mechanical Roll Co., Ltd. of China Steel Group.

Xingtai Machinery Roll Co., Ltd. of China Steel Group is located in the urban area of Xingtai City, Hebei Province, a city with a history spanning 3,500 years. The company’s plant covers an area of 1.28 million square meters, with total assets of RMB 8.94 billion, fixed assets of RMB 4.8 billion, and industrial facilities totaling over 400,000 square meters. It employs more than 3,800 workers. Its core products include rolls for rolling black and non‑ferrous metals, as well as complete sets of equipment for the iron and steel metallurgical industry.

Xingtai Mechanical Roll Co., Ltd. of China Steel Group Developed independently by Zhongxin Chuang DNTS-9 Time Server After conducting a thorough evaluation, the results consistently exceeded the specified performance parameters. We are highly satisfied with both our product quality and after-sales service, and have proceeded smoothly with procurement and deployment.

The DNTS-9 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an advanced, intelligent, high-precision NTP network time server. The DNTS-9 obtains standard time information from navigation and positioning satellite systems such as GPS, BeiDou, GLONASS, and Galileo, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time. When using GNSS satellite receivers, users can define priority levels and configure single-receiver/dual-receiver or single-antenna/dual-antenna setups; each receiver can be set to operate in standalone or combined timing modes. If both receivers and other available time sources lose signal, the DNTS-9 relies on its built-in temperature-compensated crystal oscillator or rubidium atomic clock to maintain accurate timekeeping and continuously provide time services to external devices.

DNTS-9 In addition to serving as a primary network time‑synchronization device, it can also function as a secondary time server, enabling more effective time synchronization across large‑scale network environments. The DNTS‑9 network time server is extremely easy to install and use: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization for all devices on the network.
