Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
as shown in fig. 1-5, molten metal sampler, including sampling spoon 1, thief rod 2, sample locating piece 3, insulator spindle 4, bolt 5, protective layer 6, thief rod 2 is connected on sampling spoon 1, and sample locating piece 3 establishes on thief rod 2, and insulator spindle 4 is connected with thief rod 2, and bolt 5 is used for avoiding insulator spindle 4 and thief rod 2 to drop, and protective layer 6 is used for preventing that thief spoon 1 from melting.
As shown in fig. 2 and 5, the sampling spoon 1 is cup-shaped and made of metal material, in the embodiment, iron is selected for use, the lower end face of the sampling spoon 1 is a plane, the upper end face is also a plane, the spoon mouth is vertically upward and has a certain depth, all surfaces are coated with the protective layer 6, the protective layer 6 is made by mixing graphite powder and clay, the high temperature resistance effect is good, the sampling spoon 1 can be protected, the sampling spoon 1 is prevented from melting at high temperature, and in order to ensure the high temperature resistance effect of the protective layer 6, the thickness of the protective layer 6 is 8 mm.
As shown in fig. 2 and 5, 2 connections on sampling spoon 1's outer wall in the slant of thief rod, in this embodiment, adopt welded connection, thief rod 2 has specific angle with sampling spoon 1's outer wall in the slant, has avoided 2 vertical settings of thief rod, though get the risk that liquid is convenient but scald operating personnel easily, has also avoided 2 levels of thief rod to set up, the inconvenient problem of sample both can guarantee the risk of avoiding high temperature scald simultaneously of the convenient sample. In this embodiment, sampling rod 2 is made by the metal, specifically is made for iron, and the coating has the same protective layer 6 of making by graphite powder and clay on sampling rod 2 with sampling spoon 1, and the thickness of coating is 8 mm.
