Description
Technical Field
The utility model relates to an appurtenance that spectrum sample that uses carries out the grinding when inspection molten steel, specifically speaking are grinding fixing device of cake shape spectrum sample for molten steel inspection.
Background
In the metallurgical industry, in order to grasp the chemical components of molten steel in a converter in time, two cake-shaped molten steel spectrum samples with the diameter of 30 x 5 are taken out from the molten steel in the converter by a vacuum sampler after melting for a period of time, an analyst needs to hold the cake-shaped molten steel samples by hands to grind the samples on a spectrum sample grinder after cooling so as to remove an oxide layer on the surface of the cake-shaped molten steel samples, and then the analyst uses a spectrum instrument to excite and analyze so as to obtain the numerical values of chemical elements such as C, Gi, P, S, Mn and the like. These values instruct steelmaking operators to increase and decrease various alloy raw materials in the furnace, and then steel grades such as No. 45 high-quality carbon steel, 20GrMnT, gear steel, spring steel and the like can be smelted as required. The disadvantages are that: because the thickness of this kind of cake shape molten steel spectrum sample is 5mm, when the analyst held the grinding on spectrum sample grinder with bare-handed, easily the hand is wounded or scald hand, and is very dangerous, and the grinding is inconvenient moreover, and efficiency is lower.
Disclosure of Invention
An object of the utility model is to provide a simple structure, convenient operation is fixed firm to cake shape spectrum sample, and the convenience of unloading, operating personnel's hand direct contact cake shape spectrum sample not, and in the grinding process, can not cause the injury to operating personnel, safe and reliable's grinding fixing device of cake shape spectrum sample for molten steel inspection.
In order to achieve the above purpose, the utility model adopts the technical scheme that: this grinding fixing device of cake shape spectrum sample for molten steel inspection, including urceolus and magnet, its characterized in that: the inner cylinder is arranged in the cavity of the outer cylinder in a threaded connection mode, the central axis of the outer cylinder is superposed with the central axis of the inner cylinder, a sample clamping groove matched with the cake-shaped spectrum sample is formed in the lower port of the outer cylinder, a rotary sleeve is fixedly arranged at the upper end of the inner cylinder, a groove is formed in the bottom panel of the inner cylinder, a magnet is arranged in the groove, and the magnet is fixedly connected with the bottom plate of the inner cylinder through a bolt; the diameter of the inner cavity of the sample clamping groove is larger than the outer diameter of the inner cylinder.
The diameter of the inner cavity of the sample clamping groove is 32 mm, and the depth of the inner cavity is 3 mm.
The upper port of the inner cylinder is provided with a plug.
The outer diameter of the inner cylinder is 20-25 mm.
The beneficial effects of the utility model reside in that: simple structure, convenient operation is fixed firm to cake shape spectrum sample, and the convenience of unloading, operating personnel's hand direct contact cake shape spectrum sample not, and the grinding in-process can not cause the injury to operating personnel, safe and reliable, labour saving and time saving has improved work efficiency.
