Description
Technical field
The utility model relates to a kind of ferroalloy melt sampler, especially a kind of vanadium iron stokehold melt sampler.
Background technology
In the ferroalloy production run, adopt traditional chemical analysis, can not satisfy the needs of ferroalloy smelting control.Spectral analysis has progressively been adopted in the ferroalloy on-the-spot sample analysis, and the prerequisite that adopts spectral analysis is will produce to satisfy to analyze the sample that requires.
More than the vanadium iron melt temperature height to 2000 ℃, mainly contain the sampling of paper tube sampler and the melt casting dual mode of taking a sample for the sampling of high-temperature fusant.Because the vanadium iron bath surface has the above slag blanket of 400mm, when adopting the sampling of paper tube sampler, sampler is not also inserted in the vanadium iron melt, and original mold seals promptly and opened by molten, and the whole of taking-up are slag, can only adopt melt casting sampling mode.
The Chinese patent disclosed on February 18th, 2009, that notification number is CN101368888 " a kind of aluminum alloy spectrum analysis sample mold ", and the Chinese patent disclosed on July 29th, 2009, that notification number is CN201281669 " liquid metal chemical composition spectral analysis sampling mold ", complex structure, and adopt the Quench mode to cool off, be not suitable for the vanadium iron sampling.
The Chinese patent disclosed on Dec 29th, 2004, that notification number is CN2667483 " stokehold pig iron sampling mould ", though its casting mold is simple in structure, but the easy melting loss of mould, cause sample contamination, and this mould also is to adopt the Quench mode to cool off, and institute's sample thief is prone to crackle, is difficult to produce the vanadium iron sample that meets the spectral analysis requirement, sample is cracked fully when serious, can't realize sampling.
The utility model content
Existing produce the low deficiency of spectral analysis sample qualification rate with the melt casting in order to overcome, technical problem to be solved in the utility model provides and a kind ofly can improve the vanadium iron stokehold melt sampler that sample is produced qualification rate.
The technical scheme that its technical matters that solves the utility model adopts is: vanadium iron stokehold melt sampler, comprise sample spoon and cooperatively interact, separable base plate and original mold, have die cavity on the original mold, described base plate is made with fire resistive material, and described base plate is the plane towards the workplace of die cavity.
Described die cavity is shaped as two sections cylinders that radius is different that are connected smoothly, and wherein the cylinder that diameter is bigger is at close base plate one end.
Connect with arc transition between two sections cylinders of described die cavity.
Described sample spoon is with the high temperature resistant stainless steel material.
Described sample spoon comprises kettleholder and is connected the spoon body of kettleholder one end, is solid rod iron near the kettleholder leading portion of spoon body, is hollow steel pipe away from the kettleholder back segment of spoon body.
The beneficial effects of the utility model are: simple in structure, be easy to processing, realized the quick sampling of vanadium iron stokehold melt, the difficult moulding of high temperature alloy sample more than 2000 ℃, easily segregation, a difficult problem easy to crack have been solved, obtained sample has been avoided defectives such as crackle, slag inclusion, pore effectively, can satisfy the spectral analysis requirement fully, be mainly used in the vanadium iron field of smelting.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, vanadium iron of the present utility model stokehold melt sampler comprises sample spoon 1 and cooperatively interacts, separable base plate 3 and original mold 2, have die cavity 20 on the original mold 2, described base plate 3 is the plane towards the workplace of die cavity 20, make things convenient for the cooled processing of sample, slag inclusion in the casting process and issuable bubble are to the direction come-up away from base plate 3, basically avoided sample surfaces bubble and slag inclusion to occur, because base plate 3 is made with fire resistive material, has certain insulation effect, compare with existing sampler and to have slowed down cooling velocity, can prevent that vanadium iron melt cooling is too fast and ftracture, substantially stopped the crackle generation, above scheme is compared with existing stokehold casting and sampling device, has improved the qualification rate of sampling effectively.
As shown in Figures 2 and 3, solidify the demoulding of the sample of back formation for ease of alloy solution, described die cavity 20 be shaped as two sections cylinders that radius is different that are connected smoothly, help separating of original mold 2 and sample, and wherein the cylinder that diameter is bigger need be separable original mold 2 and sample with carrying on the original mold 2 only near base plate 3 one ends.
As shown in Figure 3, for making things convenient for the processing of original mold 2, connect with arc transition between two sections cylinders of described die cavity 20.
As shown in Figure 3, for reducing in the sampling process the pollution of molten iron, described sample spoon 1 is with the high temperature resistant stainless steel material.
As shown in Figure 1, described sample spoon 1 comprises kettleholder and is connected the spoon body 11 of kettleholder one end, kettleholder leading portion 12 near spoon body 11 is solid rod iron, kettleholder back segment 13 away from spoon body 11 is a hollow steel pipe, such structure can effectively alleviate the weight of sample spoon 1, improve sampling efficiency, realize sampling fast, help improving the accuracy of spectral analysis.After can simply adopting one section high temperature resistant stainless steel pipe to seal an end with corrosion resistant plate, makes spoon body 11.
