Abstract
The invention provides a slag sampler and its use method. The sampler includes a liquid cup and a lifting rod fixed on one side thereof. The liquid cup is composed of a cylindrical body and a valve plate that is movably connected to the cylindrical body bottom through 2 axle holes. One valve plate trunnion and a cross arm outside the cylindrical body are in fixed connection at a 90-degree angle. A support is disposed over the axle hole on the cross beam side. An upper pull rod equipped with a baffle plate at the top end and sleeved with a spring passes through the support, and its lower end is movably connected to a lower pull rod, the other end of which is in connection with the outer end of the cross beam. The upper end of a clip hook is in movable connection with a ring at the top of the upper pull rod. The hook at the lower end of the clip hook is hooked at the lower end of the support, and an unlocking arm is disposed outside the clip hook. The use method comprises: inserting the sampler into the slag to certain depth, knocking the unlocking arm from bottom to top to make the lower end of the clip hook break away from the support, letting the valve plate turn by 90 degrees, sealing the slag entering the liquid cup therein, and taking the sample out after the slag solidifies. By applying the slag sampler provided in the invention, the slag samples at different depths between an upper surface and the interface of slag and a molten metal can be accurately picked up in refining and continuous casting processes during steelmaking.
Description
Technical field
The invention belongs to slag sampler technical field, relate in particular to the sampler that to extract different depth slag sample in a kind of Metal Melting, refining and casting process.
Background technology
In the refining of making steel, casting process, slag is not to be in complete admixture, especially in the refining process of the equipment such as RH, VD, CAS-OB, distance different (being the slag of different depth) because of the distance slag interface, and the position of horizontal direction is different, the degree that slag participates in slag-metal reaction is different, thereby its composition is different.In order to estimate and improve slag to liquid steel desulphurization, dephosphorization, and the effect of removing snotter in molten steel, the sample that obtains the diverse location slag is significant.For this reason, people have done multiple trial, but there is no at present the slag sample that effective method removes to obtain different depth.
At present, the method that mostly adopts steel pipe to dip, its operating process is: steel pipe is inserted slag from slag top until molten steel, and the cooling effect of invar pipe to slag, slag sticks on steel pipe, with this slag as sample, shortcoming is that this method can't determine that institute's sample thief has all comprised the slag of which degree of depth, and each layer percentage is difficult to determine, therefore, can't know the one-tenth grading information of different depth slag with the method.
" combined type molten steel, dross sampler (CN201293733Y) relate to a kind of sampler to patent, be connected with cup in the sleeve pipe lower end, the embedded molten steel cup with the cup plug of cup, the kettleholder upper end of slag spoon is connected on the regulating ring that is set in sleeve pipe top, with adjustment slag spoon position, thereby can take simultaneously molten steel and slag sample.Patent " furnace cinder sampling apparatus for converter sublance composite probe " (CN201265022Y) relates to a kind of sampler, is made of fixing slag sampler on the main paper tube of combined probe revolving furnace sublance, combined probe, the main paper tube of probe and slag sampler.Described slag sampler is by the screw hole group all-in-one-piece combination on the vertical steel plate, annulus main body, retainer plate and the retainer plate that are welded on the annulus main body, cooling effect by vertical steel plate glues gets slag specimen, the deficiency that exists in above-mentioned two pieces of patents is: can not the district office get the slag blanket position of slag specimen under in the vertical direction, thereby can not reflect and the real conditions of each layer slag can not provide accurate data to scientific research and production.
Summary of the invention
The object of the invention is to overcome the problem that the slag sampling exists and a kind of dross sampler and using method thereof be provided, in the refining that can obtain to make steel, casting process from upper surface to the slag sample slag and molten metal interface different depth.
the present invention mainly comprises the liquid cup and is fixed on the shadoof of one side, the liquid cup is combined by cylindrical shell and the valve plate that is movably connected in cylinder body bottom by 2 axis holes, a valve plate gudgeon becomes 90 ° to be fixedly connected with cylindrical shell transverse arm outward, be provided with bearing above transverse arm side shaft hole, the upper end is provided with baffle plate and cover has the upper connecting rod of spring to be through on bearing, its lower end and lower link are flexibly connected, the outer end of the other end connecting cross arm of lower link, the annulus on snap fit upper end and upper connecting rod top is flexibly connected, but the hook clasp joint of lower end is in the lower end of bearing, the outside of snap fit is provided with the unlatching arm.When utilizing the spring linkage pull rod, the interlock valve plate makes valve plate can realize the upset of vertical and horizontal level.
Cylindrical shell is combined by two and half cylindrical shells.
The corresponding semi-circular hole that axis hole is offered by two and half both sides of the edge, cylindrical shell bottom consists of.
The using method of dross sampler comprises the following steps:
1) valve plate of dross sampler is connected with cylindrical shell with the cooperation of gudgeon by axis hole, if cylindrical shell is combined by two and half cylindrical shells, two and half cylindrical shells are fixed together in the groove of half drum surface setting with steel wire, grab is hooked in the bearing lower end, this moment, spring was compressed, the transverse arm level, valve plate is vertical;
2) sampler is inserted in slag, until sampler end immersion molten metal certain depth;
3) hold the unlatching arm that the instrument such as stock knocks the grab outside from the bottom up, make the lower end of grab (2) break away from bearing, this moment, upper connecting rod under the effect of Compress Spring popped up, under the pulling of pull bar, 90 ° of transverse arm and valve plate upsets are sealed the slag that enters the liquid cup up for safekeeping in the liquid cup;
4) propose dross sampler, stopped 10 minutes, sample solidifies;
5) after sample solidifies, sample is taken out, if cylindrical shell is combined by two and half cylindrical shells, turn on steel wire, with two and half cylindrical shells separately, take out sample.
Liquid cup of the present invention adopts cylindrical shell and valve plate to combine, spring and pull bar are as power and drive mechanism, upset by valve plate, realize entering and sealing of slag, can accurately extract in the refining, casting process of steel-making from upper surface to the slag sample slag and molten metal interface different depth.
