Abstract

The invention belongs to the field of ferrous metallurgy, and relates to a molten steel (or molten iron) sampling process, in particular to a sampling device, wherein continuous sampling can be performed and the sampling depth can be adjusted. The sampling device comprises an integrated control box 1 in the attached drawing, a base 2 in the attached drawing, a support 3 in the attached drawing, a rotating disc 4 in the attached drawing, rotating arms 5 in the attached drawing, gears 6 in the attached drawing, measuring guns 7 in the attached drawing, and sampling devices (various sampling devices) 8 in the attached drawing which are all connected by screw bolts and nuts in a welding way. The sampling device is characterized in that during a smelting procedure (such as LF furnace refining), continuous sampling can be performed, and the sampling depth at each time can be constant or the sampling depth can be adjusted. The sampling process can ensure the accuracy of a tapping sample and is representative.

Description

technical field [0001] The invention belongs to the field of iron and steel metallurgy, and relates to a sampling process of molten steel (or molten iron), in particular to a continuous and adjustable depth sampling device. Background technique [0002] In recent years, my country's iron and steel industry has developed rapidly, and mass production of clean steel is an important trend in future development. Therefore, in the process of iron and steel smelting, there are strict requirements on the accuracy of laboratory analysis for rapid and continuous sampling of molten steel. In order to accurately control the composition of molten steel, especially the size, quantity and distribution of harmful elements and inclusions, it is necessary to know and master the changes of molten steel in time. [0003] There are clear requirements on the liquid steel sampling process and whether the sampling is representative. Many iron and steel plants manually insert the sampler into the ...
