In the traditional heavy industry of steel metallurgy, production precision and stability directly impact product quality and enterprise profitability. Among these, temperature and humidity, as two key process parameters, have always been the focus of industry technological breakthroughs. Beijing Kunlun Zhongda Sensor Technology Co., Ltd., leveraging over twenty years of continuous research and innovation in the field of high-temperature temperature and humidity sensors, is providing reliable technical solutions to this industry challenge.
Industry-Specific Challenges: Monitoring Difficulties in High-Temperature and High-Dust Environments
The steel metallurgy production process involves extreme high-temperature environments and complex conditions of dust and corrosive gases, posing severe challenges to conventional temperature and humidity sensors. In critical processes such as sintering, ironmaking, steelmaking, continuous casting, and hot rolling, ambient temperatures often remain above 200°C for extended periods, with localized areas even reaching 500-800°C. Simultaneously, processes like water quenching and cooling introduce humidity variables, creating unique high-temperature and high-humidity working conditions. Traditional sensors are highly prone to drift, failure, or even damage in such environments, leading to data inaccuracies and impacting process judgments.
Technical Breakthrough: High-Precision Measurement Across a Wide Temperature Range of -40 to 260°C
To address this specific application scenario, Kunlun Zhongda has dedicated efforts to developing an industrial-grade high-temperature temperature and humidity sensor series. These products utilize special high-temperature-resistant polymer humidity-sensitive materials and protective technologies, combined with precise temperature compensation algorithms, achieving high accuracy and stability across a wide temperature range of -40 to 260°C. The core sensing elements, treated with specialized encapsulation processes, ensure long-term stability and reliability in high-temperature, high-humidity, and dusty environments, with a mean time between failures significantly exceeding industry standards.
Typical Application Scenarios: Full Process Coverage from Raw Material Processing to Finished Product Processing
In practical applications within steel enterprises, Kunlun Zhongda's high-temperature temperature and humidity sensors have been successfully deployed in multiple critical areas:
-
Raw Material Sintering: Monitoring humidity in sintering machine exhaust gases to optimize fuel ratios and sintering efficiency.
-
Blast Furnace Ironmaking: Real-time monitoring of blast furnace air humidity to ensure stable operation.
-
Continuous Casting Secondary Cooling: Precise control of cooling zone humidity to improve the internal quality of cast billets.
-
Steel Rolling Heating Furnaces: Monitoring furnace atmosphere humidity to prevent excessive oxidation of steel products.
Measured Performance: Validating Product Reliability in Harsh Environments
After deploying Kunlun Zhongda's high-temperature temperature and humidity sensors in the continuous casting workshop of a large steel group, precise monitoring of the secondary cooling zone humidity was achieved. During one year of continuous operation, the sensors withstood harsh conditions including over 85% humidity, prolonged temperatures above 150°C, and significant iron oxide dust. The data collection completeness rate exceeded 99.7%, effectively supporting the optimization of the enterprise's continuous casting process and improving the billet qualification rate by 0.3 percentage points.
Continuous Technological Innovation: From Single-Point Measurement to System Solutions
Building on extensive experience in industrial applications, Kunlun Zhongda is transitioning from a single sensor supplier to a provider of system solutions. The newly developed intelligent high-temperature temperature and humidity sensors integrate wireless transmission and self-diagnostic functions, enabling real-time data upload and early warning of potential failures. Additionally, the company's dedicated data analysis platform can perform in-depth mining of multi-point measurement data, providing data support for process optimization.
Industry Value Creation: Assisting Steel Enterprises in Digital Transformation
The widespread application of Kunlun Zhongda's high-temperature temperature and humidity sensors is helping steel metallurgy enterprises transition from experience-based control to data-driven operations. By obtaining accurate and reliable process environment data, enterprises can control production processes more precisely, reduce energy consumption, improve product quality, and ultimately enhance market competitiveness.
Looking ahead, as the steel industry advances further in digital transformation, the demand for reliable monitoring in high-temperature environments will become more urgent. Beijing Kunlun Zhongda will continue to deepen its expertise in high-temperature sensing technology, offering more comprehensive solutions for improving quality, efficiency, and green development in the steel metallurgy industry through continuous technological innovation and product iteration.
