Detection crystallizer in liquid steel level and in real time liquid level signal give central processor unit PLC, PLC according to actual liquid level with
Liquid level requirement is set, comprehensive Actual Casting Speed and stopper opening degree, to adjust stopper opening degree, therefrom packet stream enters crystallization to control molten steel
The flow velocity of device, so that the molten steel liquid level in crystallizer keeps constant in casting process, compared to other tank level control systems, electricity
Magnetic-type Mould Level Control System control accuracy is higher, can reach ± 1.8mm.But electromagnetic type Mould Level Control System pair
External condition requires tighter, if subjected to the accuracy of interference, then influence liquid level examination and control.
Continuous crystallizer protecting slag liquid separation slag blanket, sinter layer, slag layer three-decker, played in casting process very heavy
The metallurgy action wanted, liquid slag layer thickness are to weigh covering slag lubrication and the very important index of heat transfer property, therefore in continuous casting
During need detect crystallizer in liquid slag layer thickness.

In use, interference can be produced to electromagnetic type Mould Level Control System in formula Mould Level Control System, and influence liquid level
Accurate control.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provide a kind of to crystallizer electromagnetic liquid
Level controlling system does not produce the round mold covering slag melt cinder thickness applied to crystallizer electromagnetism tank level control system of interference
Spend measurement apparatus.
To achieve these goals, the utility model adopts the following technical scheme that：A kind of round mold protects slag liquid
Thickness of slag layer measurement apparatus, including support, the pedestal upper end are provided with leader, measurement are offered on the support at handle both ends
Hole, measurement silk is penetrated in measured hole；Described water and support is wood materials, water by glue bonding on support.
The length of the support is the 1/3 of round mold diameter, and width is the 1/4 of length, thickness 20mm.
On support a measured hole, a diameter of Φ 2.5mm of measured hole are bored every 40mm.
Measurement silk is coppered steel wire, a diameter of Φ 1.5mm of measurement silk.
Good effect is as follows caused by the technical solution of the utility model：The utility model is consolidated using wood materials and glue
It is fixed, interference is not produced to crystallizer electromagnetism tank level control system, while multiple measured holes are set, measurement silk is set in measured hole,
It can be used to measure the crystallizer protecting residue liquid slag layer thickness of diverse location in round mold by measuring silk.
