Abstract
The utility model relates to a molten metal sampling device, which is composed of a casting mould which is arranged in a paper tube, a slag preventing cap and a quartz guide tube. The utility model is characterized in that a deoxidizing melting bath is arranged between the quartz guide tube and the casting mould, and the quartz guide tube is also arranged between the deoxidizing melting bath and the casting mould. The front of the quartz guide tube is provided with a time delaying and protecting cap, the casting mould forms an elliptic shape, and the elliptic centre position and a neck part are thicker. The back end of the casting mould is provided with a metal liquid scum collecting chamber. The utility model has the advantages of high sampling success ratio, convenient use and low cost and can be widely used for the sampling of various molten metals.
Description
The utility model relates to a kind of motlten metal sampler, particularly relate to a kind of be used for metal smelting furnace or ladle, jar in, refining bag sampling device.
In smelting iron and steel, chemical constitution is with carrying out of smelting and constantly change, therefore require to grasp the correlation values of chemical change, this will gather sample analysis according to production requirement and determine material and chemical analysis, judge whether reach technological process of production requirement.
At present, in smelting iron and steel, take a sample in the motlten metal stove or in the jar, usually adopt paper tube mold direct-insert sampler as shown in Figure 1, it mainly is by inside and outside paper tube 8,9, is arranged on the mold 7 in the paper tube, mold generally is to form a flat plate-like accommodation space by two module combination backs, insert a quartz conduit 5 that has slag-proofing cap 2 at the mouth of pipe place of mold 7, around quartz conduit 5, fill the fire cement material, and with break cap 1 shutoff paper tube 9 outward.This sampler has following deficiency: the one, and the quartz ampoule inlet of sampler directly links to each other with mold, when the break cap dissolves, when molten steel static pressure is big, molten steel directly enters in the mold 7 from the quartz conduit inlet, in mold 7, mix with deoxidizer 6, its deoxidizer 6 is generally based on aluminum metal, proportion is lighter, floats over to cause surperficial deoxidizer residual after specimen surface cools off, and influences general analysis of light and chemico-analytic accuracy and increases the sample processing time.The 2nd, because each position thickness of sampler mold is identical, the centre is slower when cooling off because of sample, so easy generation sample composition inequality, and surface irregularity is prone to and is mingled with phenomenon.The 3rd, when need are got two kinds of samples, take a sample respectively with two sampler, both increased cost, also complicated on the working routine.
The purpose of this utility model provides and a kind ofly can prevent impurity, and especially slag particle enters in the sampling mold, the mold good permeability, the sample cooling evenly, surfacing, quality is good, easily processing, the motlten metal sampler that sampling efficiency is high.
Another purpose of the present utility model provides a kind of job procedure of simplifying, and gets the motlten metal sampler of two samples simultaneously.
It is shallow that another purpose of the present utility model provides a kind of blowout prevention, the motlten metal sampler of can be used in ladle, the jar, refining bag stove opening occasion being taken a sample.
The utility model is achieved in that it is by having a mold that is arranged in the paper tube, be provided with a quartz conduit of passing paper tube band slag-proofing cap on mold top and form, and is characterized in that:
A: between quartz conduit and mold, be provided with the deoxidation bath, between deoxidation bath and mold, also establish a quartz conduit, and before quartz conduit, be provided with the delay protection cap;
B: mold is an ellipse, and this disciform centre and neck are thicker;
C: be provided with the metal liquid scum collection chamber in the mold rear end.
The utility model has the advantages that: owing to adopted the quartz ampoule inlet to be installed separately, and set up the deoxidation bath, molten steel can not directly be impacted mold, motlten metal has not only reached the effect of reducing pressure after entering the deoxidation bath, and can make deoxidizer fully miscible with molten metal solutions, and the complete noresidue of deoxidation, the mold of different-thickness makes the sample cooling evenly, the surface is very smooth, has reached the high purpose of the good efficient of sampling quality.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structural representation of former sampler.
Accompanying drawing 2 is a structural representation of the present utility model.
Accompanying drawing 3 is the cut-open view of the utility model mold.
Accompanying drawing 4 adopts the synoptic diagram of two molds for the utility model.
Accompanying drawing 5 is the structural representation of the utility model band blowout prevention shallow-layer.
Structure of the present utility model is shown in accompanying drawing 2, it is by having a mold that is arranged in the paper tube, being provided with a quartz conduit of passing paper tube band slag-proofing cap on mold top forms, it is characterized in that, between quartz conduit 3 and mold 8, be provided with deoxidation bath 4, between deoxidation bath 4 and mold 8, also establish a quartz conduit 7, and before quartz conduit 7, be provided with delay protection cap 6, break cap 1 dissolves after by the molten steel slag blanket, tin hat 2 is by dissolving behind the scum layer, and enter in the deoxidation bath 4 by quartz ampoule 3, under the effect of delay protection cap 6, molten steel can keep for 2 seconds in deoxidation bath 4, can guarantee during this that molten steel fully mixes with deoxidizer 5, but also reached the purpose that reduces pressure, metal liquid is entered in the mold 8 with the static pressure state; Mold of the present utility model is designed to ellipse, and its ellipse mold is convenient to excitation of spectra point and is distributed, and this disciform centre and neck are thicker, see accompanying drawing 3; For making the ellipse mold be easy to make, mold of the present utility model adopts powdered-metal compression moulding, and the advantage of this mold is a good permeability, easily processing, and cost is low, and the sample cooling is evenly.And be provided with metal liquid scum collection chamber 9 in the mold rear end.Because the metal liquid that enters behind the mold is the static pressure state, so slag liquid upwards floats in the collecting chamber 9, will be full of metal liquid in the mold this moment and do not have scum silica frost and remain in a standstill.
Main points of the present utility model also are to be arranged side by side two two molds 8 by powdered-metal compression moulding that have quartz conduit 7 and delay protection cap 6 in paper tube, referring to accompanying drawing 4.Two mold sampler only need primary sample by a compression moulding of powdered-metal, just can obtain two samples, have reached the effect of simplifying job procedure.
Fig. 5 shows the embodiment that has the blowout prevention shallow-layer.It is to establish one deck blowout prevention shallow-layer 11 in the outside of the paper tube 10 of above-mentioned sampler, this sampler can be used on ladle, jar in, the outer cutting opening occasion sampling of stoves such as refining bag, crystallizer, scald the people when preventing to take a sample, and can reach the purpose of depths sampling.
The utility model sampling success ratio height, easy to use, effective, and cost is low, can be widely used in various motlten metal samplings.
