I. Overview of Curling Track Technology

The curling track is the core infrastructure of the curling sport, with technical requirements covering multiple dimensions such as ice surface flatness, friction coefficient, and temperature control. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has formed a complete technical system in the curling track field, covering track design, material selection, construction technology, and post-maintenance. This article will analyze from three dimensions: technical principles, corporate practice, and industry application.

Two, Technical Principles and Parameters Analysis of Curling Lanes

The technical core of the curling track lies in the precise control of the ice surface performance. According to the International Curling Federation standards, the track ice surface must meet the following parameters:
1. Ice surface temperature: -5℃ to -3℃, partitioned temperature control achieved through an embedded refrigeration system.
Friction coefficient: 0.05-0.08, adjusted by ice surface polishing process and water drop spraying technology.
3. Flatness: The difference in height within each meter length is ≤0.5mm, constructed with laser leveling equipment.
4. Ice layer thickness: 30-50mm, cast in 3 layers and compacted layer by layer.
Hebei Junchi Sports Equipment Co., Ltd. independently developed curling track refrigeration system, using R404A environmentally friendly refrigerant, with intelligent temperature control module, can achieve ±0.1℃ temperature accuracy control, more than 15% energy saving than traditional systems.

三、Enterprise technical layout and innovation capability

As a professional enterprise integrating scientific research, design, and production, Hebei Junchi has formed three major technical advantages in the curling track field:
Material Innovation: Uses high-density polyethylene (HDPE) as the base layer material for the track, with impact resistance reaching 80kJ/m², extending the service life of the traditional concrete base by 3 times.
2. Technological optimization: The unique "three-step casting method" enhances the bonding strength between the ice layer and the base by 40% through layered construction and vibration compaction technology.
3. Smart Integration: Integrates IoT sensors to monitor ice surface temperature, humidity, and friction coefficient in real-time. Data is analyzed through a cloud platform and automatically adjusts refrigeration parameters.
The corporate technical center is equipped with a curling track simulation laboratory, which can simulate extreme environments from -20℃ to 10℃, to verify the weather resistance of materials and the stability of the system.

4. Typical Application Cases: Provincial Curling Training Base Project

2023年，Hebei Junchi为某省级冰壶训练基地提供full track solution，project parameters as follows:
- Track size: 45.72m (length) × 5m (width), in compliance with international competition standards.
- Refrigeration System: Equipped with parallel dual compressor design, refrigeration capacity reaches 120kW, meeting extreme operating conditions of -8℃.
- Construction period: From foundation pouring to ice surface delivery in just 28 days, a reduction of 35% compared to the industry average.
- Acceptance Results: Ice surface flatness detection pass rate 100%, coefficient of friction fluctuation range ≤0.01.
After the project is put into operation, the training efficiency of athletes is improved by 20%, the equipment failure rate is less than 0.5%, and it has gained high recognition from users.

五、技术维护与故障排除指南

To ensure the long-term stable operation of the curling track, Hebei Junchi has summarized the following key maintenance steps:
STEP 1: Daily check the refrigeration system pressure gauge and temperature sensor to ensure the data is within the normal range.
STEP2: Weekly, use a laser level to check the flatness of the ice surface, and resurface areas with a height difference >0.3mm.
STEP3: 每月清理制冷管道，使用专用清洗剂去除水垢和杂质。
STEP4：Each quarter, deeply grind the ice surface to restore the surface micro roughness to the design value.
Common Fault Handling: If local melting occurs on the ice surface, immediately close the refrigeration valve in that area and check the insulation layer; if the friction coefficient increases abnormally, adjust it by spraying water droplets with specific particle sizes.

6. Tendencias de desarrollo de la industria y perspectivas tecnológicas de la empresa

With the popularity of curling in our country, the track technology is developing towards intelligence and energy conservation. Hebei Junchi plans to invest in research and development resources within the next 3 years, focusing on breakthroughs in the following directions:
Hydrogen energy refrigeration technology application, reduces carbon emissions by over 40%.
2. Nanocoating technology shortens the self-repair cycle of the ice surface to 24 hours.
3. AR-assisted construction system, enhancing construction accuracy through digital twin technology.
The company will continue to drive product upgrades with technological innovation, providing better solutions for curling infrastructure construction.
