Uno, background tecnico e posizionamento industriale

Curling, as an ice sport integrating strategy, skill, and teamwork, has high requirements for track flatness, friction coefficient, and durability. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in the production of sports equipment, has extended its technical focus to the curling track field. Through independent research and development and process optimization, it has formed a full-process technical system covering design, production, and installation. The company is located in Haixing County, Cangzhou City, Hebei Province, and leverages the transportation advantages of Jingshan Expressway and National Highway 205 to provide efficient technical support and after-sales service to customers throughout the country.

II. Core Technology Analysis: Track Materials and Technology

1. Material SelectionThe track surface is made of high-density polyethylene (HDPE) material with a density range of 0.941-0.965 g/cm³, the friction coefficient is controlled between 0.05-0.08, ensuring the stability of the sliding of the curling stone. The subgrade uses reinforced concrete structure, with a thickness not less than 200mm, compressive strength reaching the C30 standard, effectively resisting the freezing deformation of the ice surface.

2. Procedura produttivaLa superficie della pista è realizzata in una sola volta con un模具 precisionato, con un errore di planarità ≤ 1mm/m, evitando deviazioni nella traccia di scivolamento delle palle. I bordi sono rivestiti con profilati in alluminio, dimensioni 60×40×3mm, con una resistenza all'urto migliorata del 40%, prolungando la durata della pista.

3. Thermal control systemIntegrates embedded heating tubes with a power density of 200W/m², controlled by an intelligent thermostat to adjust temperature, ensuring uniform ice hardness and adapting to temperature changes from -10℃ to 5℃.

Terzo, parametri tecnici e scenari di adattamento

1. Specific parametersLa lunghezza della corsia standard è di 45,72 m, la larghezza è di 5 m, il raggio dell'arco della linea di partenza è di 1,83 m, conforme alle regole di competizione della World Curling Federation (WCF). L'altezza del ghiaccio è controllata tra 30-50 mm, verificata da un livellatore laser, i dati vengono caricati in tempo reale nel sistema di gestione in cloud.

2. Adaptation scenarioAdatto per impianti sportivi professionali, centri di addestramento universitari e club commerciali di curling. L'azienda ha fornito soluzioni di piste a oltre 20 commissioni provinciali dello sport in tutto il paese, tra cui un progetto di centro di addestramento provinciale che, utilizzando le piste di Junchi, ha migliorato l'efficienza di addestramento degli atleti del 25% e ridotto l'errore di distanza di scivolamento dei curling al di sotto del 3%.

Quattro, controllo qualità e innovazione tecnologica

1. Process of inspectionEach track must undergo 72 hours of continuous load testing, simulating the high-frequency sliding scenario of curling, to detect surface wear rate and structural deformation. The test data is reviewed by the National Sports Equipment Supervision and Inspection Center to ensure compliance with GB/T 19851.13-2005 standard.

2. Innovative practices：The company collaborates with Beijing University of Physical Education to develop "Adaptive Ice Surface Adjustment Technology", which monitors the temperature and humidity of the ice surface in real-time through sensors, automatically adjusts the heating power and spray volume, reducing the fluctuation range of ice surface hardness to ±5HU (hardness unit). This technology has been applied to the venues of the 2023 National Curling Championship in China.

V, Technical Advantages and Industry Impact

Hebei Junchi extends the service life of curling track to over 8 years through material optimization, process upgrading and intelligent control technology, reducing maintenance costs by 30%. Its technical solution has been named "Famous and Excellent Product" by the Provincial Technical Supervision Bureau and included in the "Hebei Province Sports Equipment Recommendation Catalogue". Currently, the company is developing removable modular tracks to meet temporary event demands, further expanding the application scenarios of the technology.
