　　Elemental stainless steel analyzer, steel analysis instrument, sampling method for steel materials in front of the furnace
1. Elemental stainless steel analyzer, steel analysis instrument, and steel material are sampled at the tapping hole using a long handled sampling spoon to scoop out molten iron. After preheating the sampling spoon, the molten iron is scooped out again and poured into a sand mold. This cast iron is used as the sample for inspection. In the case of a large blast furnace volume, in order to obtain reliable results, a single tapping can be divided into three stages: initial, intermediate, and final, with one sample taken in the middle of each stage as the inspection sample.
2. When sampling in a ladle or mixer, a sample should be taken at the midpoint of the initial, middle, and final stages of filling the molten iron, or more strictly at the midpoint of each stage.
3. When using a cast iron machine to produce commercial cast iron, considering the changes in the composition of the molten iron during the process from the furnace to the cast iron plant, samples should be taken at the intermediate time when pouring from the ladle into the cast iron machine.
4. Sampling from molten steel in a steelmaking furnace is usually done by scooping the steel out of the furnace with a sampling spoon, removing the surface floating slag, and pouring it into a metal mold. After solidification, it is used as a sample for inspection. In order to prevent changes in the content of easily oxidizable elements in steel when it comes into contact with air, some use immersion molds or sampling guns to take samples for inspection in the furnace.
5. When sampling and submitting samples from cold raw iron blocks, it is generally necessary to randomly select three or more iron blocks from a batch of iron blocks as the submission samples. When the total amount of a batch exceeds 30T, an additional iron block is added for every 10T exceeded. Each batch of alcoholic beverages is composed of 3-7 iron blocks. When the iron block can be divided into two halves, only one half is prepared for analysis after separation.
6. Elemental stainless steel analyzer and steel analysis instrument generally cannot send samples for analysis of steel billets, and their chemical composition is determined by sampling and analysis in the ladle. At this time, various defects (precipitation, shrinkage, segregation, non-metallic inclusions, and cracks) will be present in the steel ingot. When conducting raw material analysis on steel billets used in rolling mills, the sample of the steel billet can be cut from a height of 1/5 of the raw steel ingot along the direction perpendicular to the rolling.
7. Steel products are generally not analyzed and can be sampled using cutting methods, but more samples should be taken to facilitate sample preparation.
