Detailed description of the invention
As depicted in figs. 1 and 2, a kind of self-adapting type fish torpedo ladle skimming device, including fish torpedo ladle 1, duplex type hoist engine 2, fixed pulley 3, chain 4 and slag trap 5；As shown in Figure 4 and Figure 5, it is characterised in that the top of described slag trap 5 is provided with cross-arm 6；Described cross-arm 6 is rectangular structure, and the length of described cross-arm 6 fills the diameter of mouth more than fish torpedo ladle 1, and the bottom of described cross-arm 6 is fixed with two pairs of hangers 8, described slag trap 6 upper end and hangers 8 chain connection；As shown in Figure 3 and Figure 6, the upper side of described cross-arm 6 is respectively arranged at two ends with shackle 7, and described shackle 7 is connected with the lower end of chain 4；
As shown in Figure 5 and Figure 6, described slag trap 5 is trapezoidal plate, and the top of slag trap 5 is provided with two pairs of links 9, hangers 8 chain connection bottom described link 9 and described cross-arm 6；The upper width of described slag trap 5 body fills the diameter of mouth equal to fish torpedo ladle 1；Slag trap 5 is internal uses steel, and outside arranges flame retardant coating 10, and the density of the refractory material that described flame retardant coating 10 uses is less than the density of molten iron；
As shown in figures 1 and 3, described fixed pulley 3 is fixed on the top of described fish torpedo ladle 1 tank mouth by base, and described duplex type hoist engine 2 uses steel wire rope 11 to be connected through fixed pulley 3 with the upper end of described chain 4；Duplex type hoist engine 2, after the process of lifting slag trap 5, can make slag trap 5 uniform force, and lifting process is more steady, it is to avoid the situation such as run-off the straight, collision.
As shown in figures 1 and 3, during work, rotating before molten iron toppled over by hot-metal bottle at fish torpedo ladle 1, slag trap 5 is drop to fish torpedo ladle 1 and fills in mouth by startup duplex type hoist engine 2, the bottom of slag trap 5 is goed deep in molten iron, and the cross-arm 6 on slag trap 5 top fills the upper of mouth across at fish torpedo ladle 1.Now, duplex type hoist engine 2 makes steel wire rope 11 be in relaxed state, i.e. slag trap 5 is not in free shape body by the pulling force of chain 4.
Subsequently, fish torpedo ladle 1, under the effect of its tilting mechanism, starts to be tilted towards hot-metal bottle and topples over molten iron.As it is shown in fig. 7, due to the inclination of fish torpedo ladle 1, slag trap 5 is under the effect of self gravitation, and the top of slag trap 1 is filled mouth by fish torpedo ladle 1 and blocks.Filling the diameter of mouth owing to slag trap 5 upper width is equal to fish torpedo ladle 1, so semicircle tapping hole is formed at the bottom that slag trap 5 and fish torpedo ladle 1 fill mouth, and the size of this tapping hole is fixed.
During fish torpedo ladle 1 topples over molten iron, owing to molten iron is affected by complex environment, forming part can condense iron block in its molten iron, owing to the density of iron block is less than the density of molten iron, the iron block of condensation will swim in the upper surface of molten iron.If be directly poured onto in hot-metal bottle by the molten iron in fish torpedo ladle 1, iron block will condense at the tapping hole of fish torpedo ladle 1, and the molten iron flow channel causing tapping hole is irregular, and iron flow and flow velocity are the most wayward.And this device is possible to prevent the generation of problems described above.
Shown in Fig. 7, during slag trap 5 tilts with fish torpedo ladle 1, owing to slag trap 5 is provided with flame retardant coating 10, its density is less than the density of molten iron, so slag trap 5 is acted on by buoyancy.Slag trap 5 can adjust self attitude according to by buoyancy size, the link 9 at slag trap 5 top will rotate along the hangers 8 bottom cross-arm 6, slag trap 5 realizes the inclination of himself, i.e., the bottom of slag trap 5 is stretched in molten iron, the top of slag trap 5 is more than molten iron level, so slag trap 5 can realize the stop of iron block floating to molten iron upper surface.Thus the iron block condensed is kept off in fish torpedo ladle 1 by slag trap 5, iron block will not condense in the tapping hole of fish torpedo ladle 1.Therefore, will not occur, because fish torpedo ladle 1 tapping hole iron block condenses, to cause the generation of molten iron flow channel irregular conditions, molten iron flow rates and flow to obtain effective control
Shown in Fig. 7, the operating angle of fish torpedo ladle 1 is generally 0～120 °, and before fish torpedo ladle 1 rotates 90 °, slag trap 5 top will be stuck in fish torpedo ladle 1 fills mouth always and not come off.As shown in Figure 8, when fish torpedo ladle 1 turns to 90 °, if fish torpedo ladle 1 is rotated further, slag trap 5 is affected will be filled landing mouth from fish torpedo ladle 1 by self gravitation.In order to avoid the generation of this type of situation, at this moment, open duplex type hoist engine 2, the steel wire rope 11 of duplex type hoist engine 2 is by applying a pulling force upwards by chain 4 to slag trap 5, to avoid the landing of slag trap 5, the molten iron in fish torpedo ladle 1 be dumped complete till.Duplex type hoist engine 2 will not fill mouth landing from fish torpedo ladle 1 to the pulling force size of slag trap 5 with slag trap 5 and be preferred.
After molten iron is finished down in fish torpedo ladle 1, fish torpedo ladle 1 being turned to zero-bit, then slag trap 5 is risen from fish torpedo ladle 1 by duplex type hoist engine 2 by steel wire rope 11 again.So far, the process that fish torpedo ladle 1 topples over molten iron is complete, topples over the process of molten iron at fish torpedo ladle 1, and this device is capable of stopping and condenses iron block, and is unlikely to the purpose that iron block condenses at fish torpedo ladle 1 tapping hole.
In addition to the technical characteristic described in description, it is the known technology of those skilled in the art.
