I. Technical Background and Industry Positioning

The curling track, as a core infrastructure of winter sports, directly affects the training effect of athletes and the experience of events. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has launched a special project to tackle the technical issues of curling track factories, forming a full-chain technical system covering track design, material selection, construction techniques, and maintenance. The company is located in Haixing County, Cangzhou City, Hebei Province, near the exit of Jinzhan Expressway, which offers convenient transportation and logistics support for the implementation of technology.

Part Two: Technical Analysis of Track Design

Structure Parameters: Total track length 45.72 meters, width 5 meters, ice surface thickness controlled at 5-8 cm, in compliance with the World Curling Federation (WCF) standards. The track is constructed with a double-layer structure, with a concrete foundation at the bottom and a high-density polyethylene (HDPE) ice panel on the surface. The joint gap error of the ice panels is ≤0.2 mm, ensuring the flatness of the ice surface.

2. Temperature Control System: Integrated with an intelligent temperature control module, it monitors the ice surface temperature in real-time through distributed sensors, controlling the temperature fluctuation range between -5℃ to -3℃, with an accuracy of ±0.5℃, meeting the sliding friction coefficient requirements for curling. The system supports remote control and can be adapted to different climatic conditions.

3. Drainage Design: Hidden drainage channels are set on both sides of the track, with a slope design of 1:200 to ensure rapid drainage of melting snow or clean water, avoiding waterlogging on the ice surface that may affect usage. The drainage channels are made of 304 stainless steel, with corrosion resistance for over 10 years.

3. Material Selection and Construction Technology

1. Ice Sheet Material: Made of imported high-density polyethylene (HDPE) with density ≥0.94g/cm³, impact strength ≥20kJ/m², and wear resistance up to ASTM D4060 standard. The ice sheet surface is treated with special polishing, ensuring a stable friction coefficient between 0.05-0.08, meeting professional competition requirements.

2. Soldering Technology: Utilizing hot melt welding technique, the soldering temperature is controlled at 230-250°C, with a welding speed of 1.5 meters per minute, ensuring the consistency of the weld strength with the base material. Ultrasonic testing is conducted after welding, with a defect rate ≤0.5%, guaranteeing the integrity of the ice surface.

3. Installation Process: The construction is divided into four steps: basic treatment, ice panel laying, temperature control system wiring, and drainage system installation. The basic concrete strength must reach C30, with a flatness error of ≤3mm/2m; ice panel laying should be carried out at an environmental temperature of 10-25℃, to avoid deformation due to thermal expansion and contraction.

4. Enterprise Technical Layout and Industry Applications

Hebei Junchi Sports Equipment Co., Ltd. has incorporated curling track manufacturing technology into its core R&D direction, forming an integrated service capability of "design-production-installation-maintenance." The company's products have passed the certification of the National Sports Equipment Supervision and Inspection Center and have been rated as superior products by the Provincial Bureau of Technical Supervision for many consecutive years. The service clients cover over 200 units, including colleges and universities, sports bureaus, and the military.

In a provincial curling training base project, the enterprise adopted the aforementioned technical solution. After the track delivery and 3 months of high-intensity use, the indicators such as ice surface flatness and temperature control accuracy all met the standards, earning the user's praise for "reliable technology and professional service." This case verifies the adaptability of the technical solution in the cold northern climate, providing the industry with a replicable reference template.

V. Technical Advantages and Future Prospects

Compared to traditional curling track designs, Hebei Junchi's technical solutions have improved in terms of temperature control accuracy, material durability, and construction efficiency. For instance, the intelligent temperature control system reduces energy consumption by 15%, extends the service life of HDPE ice slabs to over 8 years, and shortens the construction period by 30%. In the future, the company plans to introduce Internet of Things technology to achieve real-time monitoring and early warnings of track conditions, further promoting the intelligent upgrade of curling sports infrastructure.
