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 practices, and industry applications.

Section 2: Technical Principles and Parameter Analysis of Curling Lanes

The technical core of the curling track lies in the precise control of the ice surface performance. According to the standards of the World Curling Federation, the track ice surface must meet the following parameters:
Ice surface temperature: -5℃ to -3℃, zone 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 is ≤0.5mm, construction is carried out using 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 intelligent temperature control module, can achieve ±0.1℃ temperature accuracy control, more than 15% energy saving than traditional systems.

Part Three: Corporate Technical Layout and Innovation Ability

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 up to 80kJ/m², extending the service life of the traditional concrete base by 3 times.
2. Process 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. Intelligent Integration: Integrates IoT sensors to monitor the ice surface temperature, humidity, and friction coefficient in real-time. The data is analyzed through a cloud platform and automatically adjusts the 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 material's weather resistance and system stability.

四、Typical Application Cases: A Provincial Curling Training Base Project

2023年，Hebei Junchi provided a complete track solution for a provincial curling training base, with the project parameters as follows:
Track size: 45.72m (length) × 5m (width), in line 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: from foundation casting 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 use, the training efficiency of athletes increases by 20%, the equipment failure rate is less than 0.5%, and it has been highly recognized by users.

V. Technical Maintenance and Troubleshooting Guide

To ensure the long-term stable operation of the curling track, Hebei Junchi has summarized the following key maintenance steps:
STEP1：Daily check the refrigeration system pressure gauge and temperature sensor to ensure the data is within the normal range.
STEP 2: Weekly laser level inspection of ice surface flatness; resurface areas with local height differences > 0.3mm.
STEP3: Monthly clean the refrigeration pipeline, use special cleaning agent to remove scale and impurities.
STEP 4: Each quarter, deeply grind the ice surface to restore the surface micro roughness to the design value.
Common fault handling: If there is local melting on the ice surface, the cooling valve in that area should be closed immediately and the insulation layer checked; if the coefficient of friction is abnormally increased, it can be adjusted by spraying water droplets with specific particle sizes.

Six, Industry Development Trends and Corporate Technology Prospects

With the popularity of curling in the domestic market, track technology is developing towards intelligence and energy saving. Hebei Junchi plans to invest in R&D resources within the next 3 years, focusing on breakthroughs in the following directions:
Application of hydrogen energy refrigeration technology, reduces carbon emissions by more than 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 the infrastructure construction of curling sports.
