The hot metal management of the foundry only relies on experience, and the old workers' proficiency, sense of responsibility, and work attitude can no longer meet the production needs. The composition of the molten iron is very volatile, and it is difficult to control it manually within the corresponding range required. With the continuous development of casting production, the degree of mechanization and automation is increasing. The composition (carbon content, silicon content) is of great significance for ensuring the casting quality.
The carbon-silicon analyzer in front of the furnace determines that the content of molten iron is a unique place of the thermal analysis instrument, and any other component analysis method cannot be substituted. The fast carbon and silicon analyzer in front of the furnace can detect the molten iron analyzer, which is also an advantage that cannot be compared with spectral analysis and chemical analysis.
The carbon-silicon analysis instrument in front of the furnace is easy to use and is applied on the site. It only needs the furnace operator to operate it. It does not need to switch the daily use and maintenance costs. Compared with other analysis methods, it is lower. Furnace carbon-silicon analyzer can measure the carbon equivalent CEL, carbon content C%, silicon content Si%, sample temperature TM, liquidus The temperature TL and the solidus temperature TS are measured in 90 seconds.
The carbon-silicon analyzer in front of the furnace uses the principle of thermal analysis. It has the characteristics of fast test speed, stable and reliable operation, and the mathematical model in the machine can be used in foundries with different production conditions after actual correction. Some people call the cooling curve in the thermal analysis of casting the "fingerprint of metallurgical quality". The basic principle of rapid prediction and prediction of the quality of the casting before the furnace is based on the thermal analysis instrument to record the cooling curve of molten iron in a specific sample cup. . Then quantitatively calculate the chemical composition and mechanical properties of the molten iron according to the change of the characteristic value on the cooling curve; or use the solidification thermal effect parameters to qualitatively evaluate the graphite morphology and solidification quality of the cast iron. Quantitative thermal analysis is of practical significance for controlling the composition of molten iron and quickly evaluating the mechanical properties of castings; qualitative thermal analysis has important guiding significance for controlling the solidification quality of molten iron.
The carbon-silicon analyzer in front of the furnace can quickly and accurately measure the carbon-silicon composition of the molten iron before the furnace, which is the key to control the quality of the casting. If there is a long period of non-continuous use, there should be more than 17 hours of continuous power-on time once a week to charge the reference comparison battery and the battery that keeps memory in order to maintain the accuracy of the instrument.
