Needle sampler

The sampler is mainly used in the sampling of converter, ladle, continuous casting tundish and refining furnace. The samples of molten steel in ladle can be taken out in 3-5 seconds, and then sent to the laboratory to analyze various elements in molten steel by spectral analyzer. To further control the quality of steel.

Samplers are classified according to function and structure:

First, the sampler can be divided into hot metal sampler, molten steel sampler, ultra-low carbon sampler, needle sampler, vacuum sampler and so on.

Second, the molten steel sampler, molten iron sampler, ultra-low carbon sampler mainly analyzes the content of carbon, silicon, sulfur, phosphorus, manganese and so on in molten steel.

Needle sampler and vacuum sampler as long as the content of oxygen and nitrogen in the molten steel is analyzed. Four, the sampler sample box has round, oval, double thickness type, hot metal type, quartz tube type, etc.
