Description
Technical field
The utility model relates to metal smelt technical fields, more particularly, to a kind of slag flushing trough lining board.
Background technique
Blast furnace flushing cinder Hydraulic transportation is the important link for guaranteeing entire ironmaking production technique and operating normally, and is used for
The hydraulic discharged slag ditch of Hydraulic transportation be related to flushing cinder water, hydraulic pressure, slag runner end face and flushing cinder nozzle profile size calculating and
Slag runner arrangement form and gradient setting etc..In the application of hydraulic discharged slag ditch, wearability and heat-resisting quantity are to influence it to use the longevity
An important factor for life.In the prior art, blast furnace sluice is made of external mold and interior lining panel, and interior lining panel is set as U-shaped structure,
When in use, acid clinker can be dynamic along the U-shaped board surface current of interior lining panel with one stream of water, during flushing cinder, clinker meeting
The most middle section flowing in U-shaped board face is concentrated on, several times repeatedly after flushing cinder, the plate face of the liner plate of blast furnace slag flushing ditch can be worn out
One recess, as a long time, the recess of increased wear, the plate face of the liner plate of blast furnace slag flushing ditch can be increasing, finally leads
The case where causing liner plate to be broken reduces the service life of blast furnace sluice.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of structures simply, can reduce wear intensity, to mention
The slag flushing trough lining board of high life.
The utility model is the technical scheme adopted is that a kind of slag flushing trough lining board, including a liner plate ontology, the liner plate
Ontology includes two vertical side walls and the plate that is arranged between two side walls, and the plate includes erosional layer, described to wash away
Layer includes wash surface, and the wash surface includes two concavity arc surfaces and the convex arc surface for connecting two concavity arc surfaces.
The beneficial effects of the utility model are: slag flushing trough lining board using the above structure, by the wash surface of slag flushing trough lining board
Two concavity arc surfaces are set and connect the convex arc surface of two concavity arc surfaces, i.e., slag flushing trough lining board includes two punchings
Brush slot, in this way, clinker single would not be flowed by a flush path, clinker is segmented into several ways diameter in flushing cinder
The case where flowing in ditch, which can wear to avoid the single concentration of slag flushing trough lining board, reduce the mill of slag flushing trough lining board
Damage degree, to improve its service life.
As preferential, the plate is also attached to the reinforcement mass below erosional layer, and the reinforcement mass is with erosional layer
The intensity of slag flushing trough lining board can be improved using the structure in integrated formed structure, to improve its service life.
As preferential, the material that the liner plate ontology uses is ZGCr26NiMo, using the structure, ZGCr26NiMo mono-
Kind high alloy material, can be improved the service life of slag flushing trough lining board.
As preferential, several protrusions are provided on the concavity arc surface and convex arc surface, the protrusion uses
Ceramic material can be accumulated on the wash surface of slag flushing trough lining board, protrusion can contribute to clinker using the structure to avoid clinker
Flowing.
Detailed description of the invention
Fig. 1 is a kind of side view of slag flushing trough lining board of the utility model；
It is as shown in the figure: 1, liner plate ontology；2, side wall；3, erosional layer；4, concavity arc surface；5, convex arc surface；6, reinforce
Mass；7, protrusion.
Specific embodiment
Utility model is further described referring to the drawings and in conjunction with specific embodiment, to enable those skilled in the art
Refer to the instruction text can be implemented accordingly, and scope of protection of the utility model is not limited to the specific embodiment.
The utility model relates to a kind of slag flushing trough lining boards, as shown in Figure 1, including a liner plate ontology 1, the liner plate ontology
1 includes two vertical side walls 2 and the plate being arranged between two side walls 2, and the plate includes erosional layer 3, described to wash away
Layer 3 includes wash surface, and the wash surface includes two concavity arc surfaces 4 and the convex circular arc for connecting two concavity arc surfaces 4
Face 5, it can be seen that, liner plate ontology 1 is that rectangular, rectangular liner plate ontology 1 is easily placed in Fig. 1；Two concavity arc surfaces 4 being arranged
And what the convex arc surface 5 of two concavity arc surfaces 4 of connection was actually formed is exactly scour trough in slag flushing trough lining board, in this way,
Clinker can be flowed along each scour trough, be avoided in original technology, and clinker is single to be flowed by a flush path,
The wear intensity for reducing slag flushing trough lining board, to improve its service life.
As shown in Figure 1, the plate is also attached to the reinforcement mass 6 of the lower section of erosional layer 3, the reinforcement mass 6 with wash away
Layer 3 is an integral molding structure, and reinforces the outside that mass 6 is coated on erosional layer 3, ensure that the intensity of slag flushing trough lining board, to mention
Its high service life.
The material that the liner plate ontology 1 uses is ZGCr26NiMo, and originally in technology, slag flushing trough lining board is using Gao Meng
Steel (ZGMn13) or heat-proof nodular cast iron, service life is all undesirable, and there is an urgent need to more conversion materials for each iron-smelter, and are somebody's turn to do
ZGCr26NiMo is that a kind of high alloy material can substantially mention the service life of slag flushing trough lining board by 10 months through overtesting
It rises to 36 months.
As shown in Figure 1, be provided with several protrusions 7 on the concavity arc surface 4 and convex arc surface 5, protrusion 7 can be with
Clinker is avoided to accumulate on the wash surface of slag flushing trough lining board, and protrusion 7 can contribute to clinker flowing.
