The performance requirements of molten steel testing equipment vary depending on the specific testing needs and application scenarios, but generally include the following aspects:
Measurement accuracy:
Temperature measurement accuracy: For the measurement of molten steel temperature, high accuracy is required, and it is generally required to be controlled within a small error range (such as within ±3℃ or even higher accuracy) to ensure accurate control of the molten steel temperature. For example, in different stages of the steelmaking process, the precise control of molten steel temperature directly affects the quality and performance of the steel. Too high or too low temperature may lead to product defects.
Composition measurement accuracy: If the equipment is used to detect the element content in molten steel, such as carbon, silicon, manganese, etc., its measurement accuracy also needs to meet the specified standards, usually measured by the error range of percentage content, to ensure the accuracy of composition analysis and provide a reliable basis for subsequent smelting adjustments.
Measurement range:
Temperature measurement range: To cover the temperature range that may occur in various stages of molten steel from furnace to casting, the common molten steel temperature is above 1000℃, and can even reach about 1600℃. The detection equipment needs to be able to accurately measure within this high temperature range.
Composition measurement range: It should be able to detect the content range of various common elements and possible trace impurity elements in molten steel to meet the composition analysis needs of different steel grades.
Response speed: The temperature and composition of molten steel may change rapidly during the smelting process. The detection equipment needs to have a fast response capability and be able to accurately obtain the measurement results in a short time (generally within a few seconds) so that the operator can make adjustments and decisions in time to avoid the production process being out of control due to measurement lag.
Stability and reliability:
Long-term working stability: In the complex environment of the steelmaking site, there may be factors such as high temperature, dust, and electromagnetic interference. The equipment needs to be able to maintain stable performance during long-term continuous operation, and the fluctuation of the measurement results is within the allowable range to ensure continuous monitoring of the production process.
Anti-interference ability: It has good anti-electromagnetic interference, high temperature radiation, mechanical vibration and other interference capabilities to ensure accurate measurement in harsh environments, and is not affected by surrounding environmental factors to cause mismeasurement or unstable measurement.
Equipment durability: The mechanical structure is sturdy, the electronic components are of reliable quality, and key components such as sensors have a long service life. They can withstand frequent use and harsh environments, reduce equipment failures and maintenance frequency, and reduce the impact on production.
Safety:
High temperature resistance: Components that are in direct or indirect contact with molten steel, such as temperature probes, sampling devices, etc., must be able to withstand the high temperature of molten steel without damage, deformation or danger. Special high temperature resistant materials and designs are usually required.
Electrical safety: The electrical system of the equipment should comply with relevant safety standards and have good insulation, grounding protection and other measures to prevent the risk of electric shock to operators, especially in high temperature and humid steelmaking environments. Electrical safety is particularly important.
Protective performance: For dangerous parts that may generate high temperature radiation, sparks, splashes, etc., there must be corresponding protective devices or measures to ensure the personal safety of operators.
Convenience of operation:
Easy to install and debug: The equipment should be easy to install and debug at the steelmaking site. The installation process is simple and quick, and does not require complex special tools or professional technicians to operate for a long time. The debugging process is easy to operate and can quickly put the equipment into normal working state.
Friendly human-computer interaction: The operation interface is concise and clear, the display screen is clear and readable, the control buttons or operation methods are easy to understand and operate, and the operator can easily perform parameter settings, measurement start, data reading and other operations, reducing operating errors and training costs.
Data storage and transmission function: It can conveniently store measurement data and has a variety of data transmission methods (such as USB interface, wireless transmission, etc.) to transfer data to a computer or other data processing system for further analysis and processing, providing a basis for production management and quality traceability.
