Blast furnace molten iron sampling device

Abstract

The invention discloses a blast furnace molten iron sampling device, which comprises a fixing support frame (2) arranged at the molten iron groove part, wherein a rotating testing gun (5) is arranged on the fixing support frame (2); the end part of the rotating testing gun (5) is provided with a sampler (1); when the rotating testing gun (5) rotates, molten iron in the molten iron groove can be scooped up through a sampler (1) arranged at the end part of the rotating testing gun (5); the molten iron sample can be put into a sample collecting device (4). The blast furnace molten iron sampling device has the advantages that the sampling position and the insertion depth are relatively fixed; the danger of personnel performing high-temperature operation near the molten iron groove can be reduced; the random performance, the instability and the like of the conventional sampling mode are avoided.

Description

technical field [0001] The invention relates to a sampling device for iron and steel or other industries where samples are collected in ditches and places where manual labor should not be too close, in particular to a sampling device for high-temperature molten iron (slag) located at a molten iron ditch of a blast furnace. Background technique [0002] In recent years, the development of my country's iron and steel industry has put forward higher requirements for clean steel production. As the main raw material for steelmaking, the composition of molten iron that meets the standards directly affects a series of links such as subsequent steelmaking and refining. Therefore, safe, rapid and accurate sampling and analysis of molten iron (slag) provides a practical basis for the blast furnace, converter smelting process and batching system. [0003] During the blast furnace ironmaking process, due to its structural characteristics, samples cannot be taken directly inside the tilt...
