Overview of furnace front molten iron analyzer:

The furnace front molten iron analyzer, also known as the furnace front rapid molten iron composition analyzer, is widely used for on-site measurement of carbon equivalent, carbon content, silicon content, pouring temperature TM, liquidus temperature TL, and solidus temperature TS in raw iron water such as gray iron, ductile iron, mare iron, and creep iron. The results are directly printed. The measurement results are directly read by digital display, and the measurement time is 2-3 minutes, which is convenient for casting engineers to mix materials on site.

　　Functional features:

1. The instrument is easy to operate, maintenance free, and can be used on site by ordinary furnace workers.

2. The instrument can measure the molten iron after spheroidization of ductile iron, which cannot be achieved by domestic instruments. This technology fills the domestic gap. The instrument can automatically control important metallurgical parameters. It automatically measures gray white solidified cast iron, eliminating manual operation. External output devices that can connect signals and measurement data (large remote displays, signal lights, computers, printers).

　Technical parameters:

1. Measurement function: Measure white cast iron, gray cast iron, and ductile iron for thermal analysis.
2. Measurement parameters: Determine the CEL, C, and SI of molten iron.
3. Measurement range: K-type (Nicr Ni) 400 ℃~1370 ℃; C 2.1~4.2% Si 0~20% CEL2.5~5.0%
4. Measurement accuracy: CEL ± 0.1% C ± 0.05% Si ± 0.1%
5. Working parameters: power supply 110~250V, power 50W
6. Printing parameters: HB, RM, PEAK, TL, CEL, SC, TS, C%, Si%

　　Sampling method and requirements for furnace front molten iron analyzer
The following methods are applicable for sampling molten iron from blast furnaces, electric furnaces, double smelting mixed furnaces, as well as from ladle and pre-treatment containers.
The molten iron may be uneven during the pouring production process. Necessary measures should be taken to make the sampling method suitable for the specific needs of the production process. For example, if the molten iron in the mixing furnace has stratification, it is necessary to ensure that the analysis can represent the entire melt when sampling.
For this batch of production, two or more samples should be taken from the smelting process, preferably around one-third and two-thirds of the time after the furnace is discharged, for measurement and taking the average value. For continuous production, sampling should be conducted at regular intervals.
The sampling method generally involves pouring the molten iron from the ladle quickly and cooling the sample as quickly as possible to obtain a white cast iron structure and prevent graphitization. The microstructure of white cast iron obtained by rapid casting is generally used for physical analysis methods.
Non rapidly cooled samples can also be used. For this case, the sample is taken from a specially cast state in a sampling spoon or from a sample rod or ingot used for mechanical property testing, which is separately cast from the same metal used to produce castings or castings.
When producing large or numerous castings, two or more samples should be taken with the user's consent.
