The laboratory of foundry industry needs the carbon silicon analysis or carbon silicon manganese analyzer of hot metal in front of furnace, the five elements analyzer (chemical analysis) in front of furnace, and the five elements analyzer is commonly known. In fact, the five element analyzer can analyze many elements (C, s, Si, Mn, P, Ni, Cr, Mo, Ti, Cu, W, V, Σ re, Mg, etc.) 2. Spectrum analyzer; 3. Metallographic analyzer; 2; 4. Universal testing machine; 5. Hardness tester; 6. Ultrasonic flaw detector; 7. Box furnace (alias: muffle furnace) 8. Drying oven, etc.
