Seat；The tube body is installed on crystallizer by bracket, and tube body its underpart is vertical with the liquid steel level in crystallizer, outer effective
In fixed inner tube and bracket；Inner tube main function is the frictional force for increasing steel wire and inner tube, prevents steel wire from sliding, and leads to side amount not
Accurately；Bracket is that device is integrally placed on crystallizer, is shaken with crystallizer, handshaking when preventing from measuring to cause to measure
Inaccuracy, and guarantee that device lower part is vertical with liquid level；The effect of limit base is to make device lower part far from crystallizer wall, prevents from measuring
Shi Gangsi contact steel billet green shell causes bleed-out or is dragged away by green shell；Its contact molten steel part of steel wire is directly melted, and molten steel is with top
Code insurance stays；By the distance between measuring steel wire bottom and bracket, and subtract mold cover plate thickness you can get it level value.
Further, the outer tube is the steel pipe that internal diameter is 8mm.
Further, said inner tube is the steel pipe that internal diameter is 3mm.
As preferred embodiment, its fusing point of the steel wire is 1250 ~ 1350 DEG C.
Further, the tube body its bent inwardly at the 150mm of front end, and be in bending structure.
Still further, the bracket be fixed on outer tube its at the 80mm of outer tube front end.
As preferred embodiment, the length is 30mm for the bracket；The limit base is set to its head of distance bracket
At portion 10mm.
Compared with prior art, the mould liquid level measuring device of the utility model, outer tube is for solid
Determine inner tube and bracket；Inner tube is used to increase the frictional force of steel wire and inner tube, prevents steel wire from sliding, and leads to side amount inaccuracy；Bracket
It is that device is integrally placed on crystallizer, is shaken with crystallizer, it is handshaking when preventing from measuring to cause measurement inaccurate, and
Guarantee that device lower part is vertical with liquid level；Setting limit base can make device lower part far from crystallizer wall, prevent steel wire when measurement from contacting
Steel billet green shell causes bleed-out or is dragged away by green shell；Its contact molten steel part of steel wire is directly melted, and molten steel above section retains；Pass through
The distance between measuring steel wire bottom and bracket, and mold cover plate thickness is subtracted you can get it level value, structure is simple, uses
It is convenient and low in cost, fast and accurately mould liquid level can be measured.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Each component mark in attached drawing are as follows: 1- outer tube, 2- inner tube, 3- steel wire, 4- bracket, 5- limit base.
Specific embodiment
Mould liquid level measuring device as shown in Figure 1, including tube body, and the steel wire 3 being installed in tube body；The tube body
It is made of outer tube 1 and inner tube 2；Said inner tube 2 is fixed on inside outer tube 1；The steel wire 3 is plugged in inner tube 2；Before the tube body
End is in bending structure, and bending angle is 120 °；Bracket 4 is welded on the inside of the outer tube 1 of the tube body；It is welded on the bracket 4
It is connected to limit base 5；The tube body is installed on crystallizer by bracket 4, and the liquid steel level in tube body its underpart and crystallizer
Vertically.
The outer tube 1 is the steel pipe that internal diameter is 8mm.
Said inner tube 2 is the steel pipe that internal diameter is 3mm.
Described its fusing point of steel wire 3 is 1250 ~ 1350 DEG C.
