Ice Curling Track Technical Overview
The curling track is the core infrastructure of curling sports, 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.

II. Curling Track Technical Principle and Parameter Analysis
The technical core of 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:
Ice surface temperature: -5℃ to -3℃, zone temperature control achieved through embedded refrigeration system.
Friction coefficient: 0.05-0.08, adjusted by ice surface polishing process and water droplet spraying technology.
Flatness: Difference in height within each meter ≤ 0.5mm, construction 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 the cooperation of intelligent temperature control module, can achieve ±0.1℃ temperature precision control, more than 15% energy saving compared with traditional system.
3. 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: Using high-density polyethylene (HDPE) as the base layer material for the track, its impact resistance reaches 80 kJ/m², extending the lifespan of the traditional concrete base by 3 times.
2. Process Optimization: The unique "Three-step Casting Method" improves 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 enterprise 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.

Typical Application Case: A Provincial Curling Training Base Project
2023年,Hebei Junchi provided a full track solution for a provincial curling training base, project parameters are as follows:
Track size: 45.72m (length) × 5m (width), in compliance with international competition standards.
Refrigeration System: Equipped with a parallel design of dual compressors, the refrigeration capacity reaches 120kW, meeting the extreme working conditions of -8℃.
- Construction period: Only 28 days from foundation pouring to ice surface delivery, 35% shorter than the industry average.
- Acceptance results: Ice surface flatness detection pass rate 100%, coefficient of friction fluctuation range ≤0.01.
The project, after commissioning, has improved the training efficiency of athletes by 20%, the failure rate of equipment is less than 0.5%, and has gained high recognition from users.
Chapter 5: Technical Maintenance and Troubleshooting Guide
To ensure the long-term stable operation of the curling track, Hebei Junchi summarizes the following key maintenance steps:
STEP1: Check the refrigeration system pressure gauge and temperature sensor daily 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.
Step 3: Clean the refrigeration pipeline monthly, using a special cleaning agent to remove scale and impurities.
STEP4: Every quarter, carry out deep polishing on the ice surface to restore the surface micro roughness to the design value.
Common Fault Handling: If local melting occurs on the ice surface, the refrigeration valve in that area should be immediately closed and the insulation layer checked; if the coefficient of friction is abnormally increased, it can be adjusted by spraying water droplets of a specific particle size.
Six, Industry Development Trends and Enterprise Technology Prospects
With the popularization of curling in the country, the track technology is developing towards intelligence and energy-saving. Hebei Junchi plans to invest in R&D resources in the next 3 years, focusing on breakthroughs in the following directions:
Hydrogen energy refrigeration technology application, reducing carbon emissions by more than 40%.
2. Nano coating technology shortens the self-repair cycle of the ice surface to 24 hours.
3. AR-assisted construction system, enhances construction accuracy through digital twin technology.
The enterprise will continue to drive product upgrades with technological innovation, providing better solutions for curling infrastructure construction.
