Abstract
The invention relates to a refractory material, in particular to a tundish current stabilizer. The structure of the container is a barrel-shaped container with an inner cavity, and the container comprises a shell and the inner cavity, wherein the section shape of the inner cavity can be divided into 4 sections from top to bottom, the 4 sections are respectively a horn-mouth-shaped opening section, a neck-mouth section with a smaller diameter than the opening section, an inner cavity section with a larger diameter than the neck-mouth section and the bottom of the inner cavity, an annular groove is formed in the lower part of the shell, and a thermosensitive material is inserted into the bottom of the shell. The flow stabilizer solves the problems that the bottom of the tundish is corroded and molten steel forms vortex, and monitors the corrosion condition of the bottom of the flow stabilizer to ensure safe production.
Description
Technical field
The present invention relates to a kind of refractory materials, especially tundish flow straightener.
Background technology
Tundish current stabilizer plays stable middle water containing opening region MOLTEN STEEL FLOW in steel smelting procedure at present, promotes
Inclusion floating, specification has a flow straightener of the small gourd shape of the big neck of the big oral area in bottom on the market, although such flow straightener
Most of functions of flow straightener on the market can be played, but during molten steel impacts flow straightener, flow straightener bottom is constantly corroded,
Staff can not observe corrosion condition, once flow straightener bottom is corroded through by molten steel, molten steel will continue to corrosion tundish,
Corrosion condition cannot such as be monitored, it is possible to bring security risk to production.
Invention content
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of with safety precaution function
Tundish current stabilizer, by the thermo-sensitive material of flow straightener bottom, once molten steel touches thermo-sensitive material by corroding flow straightener, then
Thermo-sensitive material will be transmitted a signal to by connection line in pertinent instruments, and staff is reminded to pay attention to monitoring flow straightener and centre
Packet, carries out strick precaution early.
Technical solution：In order to reach foregoing invention purpose, the present invention is specifically achieved like this：One kind is pre- with safety
The tundish current stabilizer of alert function, structure are the bulk containers with inner cavity, which is characterized in that including shell, inner cavity, inner cavity
Section shape can be divided into 4 sections from top to bottom, respectively the open section of bell shape, the eck section smaller than open section diameter,
Bigger than eck section diameter inner cavity section, intracavity bottom, lower part of the housing offer the groove of annular, and housing bottom is inserted with temperature-sensitive material
Material.Molten steel is provided and corrodes monitoring function.
Further, the thermo-sensitive material is cylindric, and pre-buried height distance intracavity bottom is 40mm.Setting monitoring is deep
Degree.
Further, the thermo-sensitive material quantity is 3.Once one goes wrong, other two can continue to monitor.
Further, between thermo-sensitive material flow straightener is converged in 120 degree of annular spreads, three connection lines of thermo-sensitive material
Bottom centre, packet outside is connected with instrument in passing through middle packet permanent liner bottom to stretch out.Expand the monitoring model of flow straightener bottom corrosion
It encloses.
Further, the thermistor length range is 40-60cm, and two conductor wires are connected below thermistor.It is anti-
Only molten steel directly melts conductor wire.
Further, it is surrounded by one layer of thermal insulation layer skin outside the thermistor.Prevent thermistor because of week to a certain extent
It encloses temperature to increase and be powered, rather than molten steel touching thermistor is powered.
Advantageous effect：The present invention has the following advantages compared with traditional technology：
1, the cavity shape of flow straightener calabash shaped, prevents flow straightener from quickly being corroded by molten steel to a certain extent.
2, by thermo-sensitive material, the case where molten steel corrodes flow straightener is monitored.

Fig. 2 is the tundish current stabilizer thermo-sensitive material vertical view with safety precaution function.
Fig. 3 is the tundish current stabilizer thermo-sensitive material sectional view with safety precaution function.
Specific implementation mode
Embodiment 1：As shown in Figure 1, a kind of tundish current stabilizer with safety precaution function, structure is with inner cavity
Bulk containers, including shell 1, inner cavity 2, the section shape of inner cavity 2 can be divided into 4 sections, respectively bell shape from top to bottom
Open section 3, the eck section 4 smaller than open section diameter, the inner cavity bigger than eck section diameter section 5, intracavity bottom 6, lower part of the housing
The groove 7 of annular is offered, housing bottom is inserted with thermo-sensitive material 8.
Embodiment 2：On the basis of embodiment 1, as shown in Fig. 2, a kind of tundish current stabilization with safety precaution function
Device, distribution of the thermo-sensitive material in flow straightener bottom is in 120 degree of annular spreads, and three connection lines of thermo-sensitive material converge at current stabilization
Device bottom centre, packet outside is connected with instrument in passing through middle packet permanent liner bottom to stretch out.Expand the monitoring of flow straightener bottom corrosion
Range.
Embodiment 3：On the basis of embodiment 2, as shown in figure 3, a kind of tundish current stabilization with safety precaution function
Device, thermo-sensitive material bottom connect two conductor wires, are connected with alarm, outside is surrounded by one layer of thermal insulation layer skin.In flow straightener work
When work, thermal insulation layer skin prevents thermistor temp to rise too fast situation to a certain extent.In flow straightener uses
When later stage residual thickness is less than 40mm, molten steel will contact thermo-sensitive material, trigger instrument alarm, at this moment can notify to produce at once
Dispatcher stops using, and ensure that the safety in production of tundish.
