Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
As shown in Figure 1 to Figure 3: slide block type converter taphole slide plate slag-blocking apparatus of the present invention comprises fixed frame 1, slider bar 2 and compresses frame 13, the lower mouth of a river 22, lower mouth of a river bearing 8; Slider bar 2 is provided with draw runner 3; Slider bar 2 is located at fixed frame 1 and compresses between frame 13, and is slidably matched with the chute of fixed frame 1; The lower mouth of a river 22, sliding sprue tile for smelting 21, lower mouth of a river bearing 8, top-fastener 9, draw runner 3 are set in slider bar 2; The lower mouth of a river 22, the distribution of sliding sprue tile for smelting 21 coaxial line; Sliding sprue tile for smelting 21 is locked on lower mouth of a river bearing 8 by top-fastener 9 and top-fastener bolt 15; In fixed frame 1, fixing nozzle brick 20, web plate 5, locking bail 14 etc. are installed.
This device is supported the use by resistance to materials such as fixed glides brick (namely fixing nozzle brick 20), sliding skateboard brick (sliding sprue tile for smelting 21), lower nozzle bricks.The invention still further relates to the compression mode of this device middle slide plate.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention making to produce stable, uniform pressure between the contact surface of slide plate nozzle brick, the technical scheme that the present invention takes is:
As shown in Figure 2, slide block type converter taphole slide plate slag-blocking apparatus of the present invention, on described compression frame 13, arrange spring application assembly, sliding sprue tile for smelting 22 is pressed on fixing nozzle brick 20 by slider bar 2 by described spring application assembly.
By being distributed in the spring application assembly compressing frame 13 both sides, the direct holddown spring of nut, by multiple independent, uniform pressed slider, form the compression mode of multiple spot Elastic Contact, act on the draw runner 3 of slider bar 2 both sides, thus make between fixed glides brick and sliding skateboard brick, to produce stable, uniform surface pressure, prevent the generation of oozing steel phenomenon.It is rational in infrastructure, safe and reliable.Rational in infrastructure, interchangeability is good, convenient disassembly, simple to operate, safe and reliable.
Described spring application assembly is distributed in and compresses frame 13 both sides, is provided with multiple independently spring cavity, every side distribution 4 ~ 8 in compression frame 13 zygomorphy, symmetrical by the plane of symmetry of slider bar 2 direction of motion.Namely spring application assembly is symmetrical in fixed frame tap hole medullary ray perpendicular to longitudinal direction simultaneously.
Described spring application assembly comprises spring capping 10, spring 11 and pressed slider 12, and described spring capping 10, spring 11 and pressed slider 12 are all arranged in the spring cavity compressing frame 13; In multiple independently spring cavity, order installs pressed slider 12, compression spring 11, spring capping 10.Be tightened onto fixed position by spring capping 10, thus utilize spring 11 pairs of pressed sliders 12 to pressurize.
Described pressed slider 12 contacts with the draw runner 3 be fixed in described slider bar 2.Elastic pressure on each like this pressed slider 12 not only evenly but also independently, compression frame 13 compresses the draw runner 3 in slider bar 2 by above-mentioned multiple pressed slider 12, each pressed slider 12 is when compressing, the spring energy of spring 11 adjusts automatically, thus makes fixed glides brick and sliding skateboard brick surface pressure stable, evenly.
The surface that described pressed slider 12 contacts with draw runner 3 is provided with lubricating oil groove.That is: each pressed slider 12 makes the foraminate groove of surface band; In the lubricating oil groove of pressed slider 12, be marked with high temperature grease, pressed slider 12, when draw runner 3 slides on the surface, can reduce frictional force;
In described compression frame 13, be provided with perfect pressure-air cooling system, namely on compression frame 13, be provided with pressure-air cooling passage, be connected in the spring cavity of each spring application assembly described pressure-air cooling channel parallel.
The compression sky compressed in frame 13 enters in each spring cavity, cooling spring 11, spring capping 10, pressed slider 12, draw runner 3, and cooling simultaneously compresses frame 13 body.Cooling air cools draw runner 3 and thermal baffle 7 respectively by the pore in pressed slider 12 and spring capping 10 again.
In the whole process used, pressurized air cools holding down assembly of spring 11, loses elastic performance to make spring 11 be unlikely to exceed use temperature.
Described compression frame 13 is connected with fixed frame 1 by the structure that is articulated and connected; And the locking pin compressed on frame 13 is fastened by the locking bail 14 be located on fixed frame 1, compression frame 13 is locked.Be connected and fixed frame 1 by hinge lock catch and compress frame 13.
The described structure that is articulated and connected is: on described fixed frame 1, arrange rotating shaft 4, compression frame 13 arranges bearing pin 6, and described rotating shaft 4 is connected with bearing pin 6 by web plate 5.
The described lower mouth of a river 22 is arranged in slider bar 2 by lower mouth of a river bearing 8, and is held out against by top-fastener 9.
Described lower mouth of a river bearing 8 arranges thermal baffle 7, and described thermal baffle 7 is fixing on lower mouth of a river bearing 8 by thermal baffle fastening piece 19.
Described slider bar 2 is provided with oil cylinder lock shaft 17, and described slider bar 2 drives oil cylinder to be connected by oil cylinder lock shaft 17 with pushing off the slag.
In use, fixed frame 1 is installed on converter taphole web plate, and oil cylinder acts on slider bar 2 by oil cylinder lock shaft 17, produces push-and-pull campaign, on the draw runner 3 of slide block 12 positive pressure that spring 11 in compression frame 13 holds down assembly in slider bar 2, do linear slide; Connecting oil cylinder pin by oil cylinder drives slider bar 2, sliding skateboard brick, lower nozzle brick, lower mouth of a river bearing 8, thermal baffle 7 etc. to do the to-and-fro movement of advancing, retreating, for opening and block steel stream.
High temperature magnet steel 16 is to hold slide plate when mechanism opening is overhauled, and avoids slide plate to topple over, comes off.
The effect of adjustment bolt 18: the relative position compressing frame 13 and fixed frame 1 is finely tuned,
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
