Furnace carbon silicon analyzer

When producing cast iron parts, the appropriate chemical composition should be selected according to the wall thickness of the casting and the casting conditions to ensure the required mechanical properties. The carbon and silicon content have a decisive influence on the metallographic structure, casting properties and mechanical properties of the cast iron. In iron production, only the carbon equivalent of the original molten iron can be determined quickly and accurately, so that it can provide necessary data for improving the quality of steel products.

The pre-furnace carbon-silicon analyzer photoelectric direct reading spectrometer can analyze the content of various elements such as carbon, silicon, sulfur, manganese, phosphorus, chromium and nickel in the metal. The following describes the method of analyzing the sample by the sample:

The standard samples that have just been purchased and the surface of the samples taken from the workshop are untreated. Spectrometers cannot directly analyze them. We need to smooth and smooth the samples to analyze them on the spectrometer. The sample tool uses a special grinding machine. The AC220V motor drives the 36-mesh sandpaper or grinding wheel to rotate. In the process of grinding the sample, we must balance the sample on the sandpaper, and apply even force. Otherwise, the ground sample will be polished. It will not be smooth and a gradient will appear. When grinding the sample, the sample should be ground in the same position, do not swing back and forth or left and right, so that the grain surface of the ground sample is always in the same direction, do not appear cross-grain. Since iron or stainless steel samples are difficult to grind, if the surface temperature of the sample is particularly high, we can use local cooling after cooling water, and then grind until the sample is smoothed and the surface texture is uniform. After the sample is ground. We can't touch the surface of the grinding by hand or other things, and don't let the dust cover the surface, which will affect the analysis accuracy.

The pre-furnace carbon-silicon analyzer photoelectric direct reading spectrometer has the advantages of fast analysis speed, good repeatability and good stability. It is widely used in metallurgy, machinery and other industrial sectors, for online analysis before smelting furnace and product inspection of central laboratory. Is one of the effective means to control product quality.
