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, particularly relate to the sampler can extracting different depth slag sample in a kind of Metal Melting, refining and casting process.
Background technology
In the refining, casting process of steel-making, slag is not in complete admixture, especially in the refining process of the equipment such as RH, VD, CAS-OB, because of the distance difference (being the slag of different depth) apart from slag interface, and the position of horizontal direction is different, the degree that slag participates in slag-metal reaction is different, and thus its composition is different.In order to evaluate and improve slag to liquid steel desulphurization, dephosphorization, and remove the effect of snotter in molten steel, the sample obtaining diverse location slag is significant.For this reason, people have done multiple trial, but there is no the slag sample that effective method removes to obtain different depth at present.
At present, mostly adopt the method that steel pipe dips, its operating process is: steel pipe is inserted slag until molten steel above slag, and because steel pipe is to the cooling effect of slag, slag sticks on steel pipe, using this slag as sample, shortcoming is, this method cannot determine that institute's sample thief all contains the slag of which degree of depth, and each layer percentage is difficult to determine, therefore, the one-tenth grading information of different depth slag cannot be known in this approach.
" combined type molten steel, dross sampler (CN201293733Y) relate to a kind of sampler to patent, cup is connected with at its lower end, the embedded molten steel cup with cup plug of cup, the kettleholder upper end of slag spoon be connected to be set in sleeve pipe top regulating ring on, to adjust slag spoon position, thus molten steel and slag sample can be taked simultaneously.Patent " furnace cinder sampling apparatus for converter sublance composite probe " (CN201265022Y) relates to a kind of sampler, is made up of, slag sampler fixed by 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 be welded in annulus main body, annulus main body, retainer plate and retainer plate, glued by the cooling effect of vertical steel plate and get slag specimen, the deficiency existed in above-mentioned two sections of patents is: can not get slag specimen slag blanket position affiliated in the vertical direction in district office, thus can not reflect the real conditions of each layer slag, provide accurate data can not to scientific research and production.
Summary of the invention
The object of the invention is to overcome slag sampling Problems existing and a kind of dross sampler and using method thereof be provided, can obtain in the refining of steel-making, casting process from upper surface to the slag sample slag and molten metal interface different depth.
The present invention mainly comprises liquid cup and is fixed on the shadoof of its side, liquid cup combines by cylindrical shell and by the valve plate that 2 axis holes are movably connected in cylinder body bottom, a valve plate gudgeon is fixedly connected with the transverse arm outside cylindrical shell is in 90 °, bearing is provided with above transverse arm side shaft hole, upper end is provided with baffle plate and cover has the upper connecting rod of spring to be through on bearing, its lower end is flexibly connected with lower link, the outer end of the other end connecting cross arm of lower link, snap fit upper end is flexibly connected with the annulus on upper connecting rod top, the hook of lower end can clasp joint in the lower end of bearing, the outside of snap fit is provided with unlatching arm.While utilizing spring linkage pull bar, interlock valve plate, makes valve plate can realize upset that is 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 is formed.
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 that half drum surface is arranged with steel wire, grab is hooked in bearing lower end, now spring is compressed, transverse arm level, valve plate is vertical;
2) sampler is inserted in slag, until molten metal certain depth is immersed in sampler end;
3) hold the instruments such as stock and knock unlatching arm outside grab from the bottom up, the lower end of grab (2) is made to depart from bearing, now under the effect of Compress Spring, upper connecting rod pops up, under the pulling of pull bar, transverse arm and valve plate overturn 90 °, are sealed up for safekeeping by the slag entering liquid cup in liquid cup;
4) propose dross sampler, stop 10 minutes, sample solidifies;
5) after sample solidifies, sample is taken out, if cylindrical shell is combined by two and half cylindrical shells, turns on steel wire, by 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, by the upset of valve plate, realize slag entering and close, can accurately extract in the refining of steel-making, casting process from upper surface to the slag sample slag and molten metal interface different depth.
