Description
Technical Field
The utility model relates to a ladle top slag sampling device, and belongs to the technical field of ferrous metallurgy industry.
Background
The ladle top slag is a main means for controlling the quality of molten steel, and the oxidation and reduction reactions of various elements in the molten steel can be controlled by adjusting the top slag components in the external refining of the molten steel furnace. The top slag can absorb oxide and sulfide inclusion in the molten steel, prevent secondary oxidation and air suction of the molten steel, and reduce the radiation heat loss of the molten steel and the like. And how to verify whether the top slag component is in a preset range, sampling analysis needs to be carried out on the ladle top slag. At present, the depth of the sampling device entering a steel ladle is difficult to control by using the device for sampling the slag sample at the top of the steel ladle, so that the slag sample is easy to be stained with cold steel, and the accuracy of analyzing the chemical components of the slag sample is reduced.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a ladle top slag sampling device aiming at the prior art, only top slag is taken without contacting molten steel, and the accuracy of slag sample chemical component analysis is improved.
The technical scheme adopted by the utility model for solving the problems is as follows: a ladle top slag sampling device comprises a handheld handle, wherein a balance rod is arranged at the lower end of the handheld handle, the end part of the handheld handle is fixedly connected with the end part of the balance rod through a connecting piece, and the handheld handle and the balance rod are in a straight line; still the activity is equipped with on the connecting piece and gets the sediment ware, it can rotate from top to bottom along the connecting piece to get the sediment ware.
The connecting piece is connected with the slag extractor through a ball joint.
Get the sediment ware and include that the sediment box is got to the open type, get sediment box one side and dwang one end fixed connection, the dwang other end is spherical structure spare.
Compared with the prior art, the utility model has the advantages that: a ladle top slag sampling device utilizes the density difference between molten steel and top slag, and a slag extractor only can extract the top slag but not contact the molten steel in the slag sampling process, thereby reducing the influence of iron oxide on the analysis of slag sample components. The method and the device have the advantages of being convenient to operate and improving the accuracy of slag sample analysis.

in the figure, 1 a handle, 2 a connecting piece, 3 a balancing rod, 4 a slag extractor, 4.1 a rotating rod, 4.2 a slag extracting box, 5 steel ladles, 6 molten steel and 7 top slag.
Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the ladle top slag sampling device in this embodiment includes a handheld handle 1, a balance rod 3 is disposed at a lower end of the handheld handle 1, a connecting member 2 is disposed between a bottom end of the handheld handle 1 and a top end of the balance rod 3, the connecting member 2 is vertically provided with a through hole, and a bottom end of the handheld handle 1 and a top end of the balance rod 3 are both inserted into the through hole, so that the handheld handle 1 and the balance rod 3 are in a straight line. The side surface of the connecting piece 2 is also provided with a spherical groove, a slag extractor 4 is arranged in the groove, and the slag extractor 4 can rotate 90 degrees up and down along the connecting piece 2.
Get sediment ware 4 and include the sediment box 4.2 of getting of open type, get sediment box 4.2 one side and dwang 4.1 one end fixed connection, the dwang 4.1 other end is spherical structure spare, and the dwang 4.1 other end locates in the recess for connecting piece 2 and dwang 4.1 ball joint are connected.
As shown in FIG. 2, when taking the top slag 7 in the ladle 5, the operator holds the handle 1 with his hand and inserts the balance bar 3 together with the slag extractor 4 into the molten steel 6. The density of the top slag 7 is 2.0-3.0g/cm3The density of the molten steel is 7.0g/cm3The gravity of the slag extractor 4 is larger than the buoyancy force applied to the slag extractor in the slag and is smaller than the buoyancy force given by the molten steel 6; the slag extractor 4 can rotate up and down 90 degrees with the connecting piece 2, so that the slag extractor 4 can always rotateThe top slag 7 horizontally sinks at the bottom of the top slag 7 and floats at the top of the molten steel 6, and the top slag 7 flows into the inner cavity of the slag taking box 4.2 through the opening of the slag taking box 4.2. The handle 1 is held by hand and is inserted into the molten steel for 3 to 5 seconds, then the molten steel can be taken out from the ladle, at the moment, the liquid molten steel is converted into solid state, the slag sample is poured to a designated place from the slag taking box, and the slag-ejecting and slag-taking operation is completed.
According to the slag sampler, the density difference between the molten steel and the top slag is utilized, the slag sampler only can take the top slag without contacting the molten steel in the slag sampling process, and the influence of iron oxide on slag sample analysis is reduced. The method and the device have the advantages that operation is convenient, and accuracy of slag sample component analysis is improved.
In addition to the above embodiments, the present invention also includes other embodiments, and any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of the claims of the present invention.
