Detailed description of the invention
With detailed description of the invention, this utility model is described in further details below in conjunction with the accompanying drawings.
As shown in figs. 1 to 6, this utility model embodiment provides a kind of for continuous casting production splashproof steel thing
Therefore pendulum groove, comprising: pendulum groove body 1.Pendulum groove body 1 is in the form of slot, such as rectangular channel.It is positioned at pendulum
Beam steel flow outlet 10 is had on the cell wall 11 of one end of groove body 1.Continuous casting production stream is opened and is watered
When starting and accident treatment, pendulum groove body 1 is arranged at below continuous casting intermediate inlet 21, in drain
Between outside bag beam molten steel 3 to continuous cast mold 4, be such as drained to be positioned at the molten steel that continuous cast mold 4 is other
Collecting tank 5, so that in it does not enter continuous cast mold 4 and reclaim tundish beam molten steel 3.During making,
Pendulum groove body 1 can be welded by plurality of steel plates, and such as thickness is the steel plate of 4～6mm, in order to grasp
Making normal work that is convenient and that do not affect continuous cast mold 4, pendulum groove body 1 is rotatably provided in continuous casting
Between below water-coating port 21, the cell wall 11 of the other end of pendulum groove body 1 is provided with action bars 6, operation
Bar 6 can provide convenient for mobile or rotation pendulum groove body 1.It is positioned at the groove of one end of pendulum groove body 1
The lower end at the end 12 connects the collar 71, is provided with axle 72, the collar 71 on continuous casting production crossbeam 7
It is rotatably provided on axle 72, thus realizes putting groove body 1 and be rotatably provided in continuous casting production crossbeam 7
On.For the flowing of beneficially tundish beam molten steel 3, between the other end and the horizontal plane of pendulum groove body 1
Distance 10 be positioned at higher than the distance between one end and the horizontal plane of pendulum groove body 1, the outlet of beam steel flow
This end, i.e. pendulum groove body 1 is inclined to set, and the angular range of inclination can be 10～20 °, example
Such as 10 °, 15 °, 20 °.Generally continuous casting tundish bottom has multiple continuous casting intermediate inlet, permissible
Putting groove each continuous casting intermediate inlet arranged beneath one, now continuous casting intermediate inlet is properly termed as even
The packet stream time mouth of a river in the middle of casting.
Upper surface at the bottom land 12 of pendulum groove body 1 is formed with the first boss 811, and during drain, first is convex
Platform 811 is positioned at immediately below middle water containing opening 21 so that tundish beam molten steel 3 first to impact first convex
Platform 811, under the peptizaiton of the first boss 811, the impact alleviating tundish beam molten steel 3 is strong
Degree, thus decrease tundish beam molten steel 3 ballistic pendulum groove body 1 spatter steel, it is to avoid spattering steel is bonded at
On continuous casting production 2, improve the safety that pendulum groove uses, reduce continuous casting production accident incidence rate.
In order to improve peptizaiton, the vertical section of the first boss 811 is preferably arc, such as semicircle.
Owing to bottom land 12 is relatively big, in order to improve bottom land 12 with the contact area of tundish beam molten steel 3
Service life and reduce the external radiations heat energy of tundish beam molten steel 3, at the bottom land 12 of pendulum groove body 1
Upper surface be equipped with bottom land flame retardant coating, it is built by laying by refractory slab and is formed.In the middle part of the end face of refractory slab upwards
Protuberance forms the first boss 811 of the length direction extension along pendulum groove body 1, the i.e. first boss 811
Formed on the upper end of formation is connected on pendulum groove body bottom land 12 between being.In other examples, first is convex
The formation of platform 811 can be directly in the upper end formation of the bottom land 12 putting groove body 1, such as pendulum groove body
1 is welded by plurality of steel plates, by welding semi-cylindrical rod iron in the steel plate upper end forming bottom land 12,
Thus form the first boss 811.
Refractory slab is split-type structural, and so so that manufacture, install and safeguard convenient, it includes phase
Being spliced to form impact zone refractory slab 81 and the downstream refractory slab 82 of bottom land flame retardant coating mutually, both are along tundish

Refractory slab can also be integral type structure, is an imposite, is built by laying on bottom land 12 by this imposite.For
Improving the high-temperature erosion-resistant erosiveness of the first boss 811, the material of impact zone refractory slab 81 is magnesia
Refractory material, the material of downstream refractory slab 82 can be silica refractory, the most cost-effective.
In order to improve the service life of cell wall 11, the medial surface of cell wall 11 is equipped with cell wall flame retardant coating,
It is built by laying by refractory brick and is formed.The top (i.e. the top of refractory brick in Fig. 6) of refractory brick is to pendulum groove body
Bending in 1 groove formed, thus the tundish beam molten steel 3 built up of protection spill pendulum groove body 1 and
It is bonded on continuous casting production 2, the angle (angle that i.e. top of refractory brick is formed with bottom land 12) of bending
Preferably acute angle, more preferably 60 °～70 °, such as, 60 °, 65 °, 70 °.In reality, can
To be whole top bending in the groove that pendulum groove body 1 is formed of refractory brick, it is also possible to be refractory brick
Operative tip bends in the groove that pendulum groove body 1 is formed, and this operative tip is positioned at the first boss 811
Both sides, this is not defined by the present embodiment.The material of refractory brick can be silica refractory, effectively
Cost-effective.
In order to reduce the tundish beam molten steel 3 directly contacted with bottom land 12, in refractory slab upper surface middle part
(i.e. in Fig. 6 from left to right direction on) is formed with the second boss 812, and it is along the length of pendulum groove body 1
Direction extends, and the first boss 811 is positioned on the end face of the second boss 812, and refractory brick is positioned on refractory slab
And be embedded between side and the medial surface of cell wall 11 of the second boss 812, now refractory slab and cell wall
11 connect, and in order to improve the sealing between refractory brick and refractory slab, both seam crossings are filled with fire-resistant
Material.So that the manufacture of refractory brick, install and safeguard convenient, refractory brick is Split type structure, its bag
Include and be mutually spliced to form the dome brick 91 of bottom land flame retardant coating, impact zone refractory brick 92 and downstream refractory brick 93,
Three sets gradually along beam MOLTEN STEEL FLOW direction；Dome brick 91 be placed in bottom land 12, cell wall 11 and fire-resistant
