SPD-V020 Multifunctional Strand Condition Monitor



Overview

In the production process of the multifunctional strand condition monitor,
in order to ensure the quality of the slab, it is necessary to strictly
control the performance and various parameters of the CCM’s guide roll
within a certain error range. Due to the continuous casting machine (CCM) is
large and in a harsh production environment, it is difficult to measure the
performance of the continuous casting machine manually, and many parameters
are difficult to measure. Therefore, it is very important to have a set of
equipment that can simulate drawing of steel billet to realize the
measurement of CCM’s various parameters and performance. The
multifunctional strand condition monitor uses various sensors to realize the
measurement of CCM’s roll gap value, the arc value of continuous casting
section, the rotation quality of the rolls, and the water spray pressure
under the condition of simulating drawing of steel billet. Therefore, the
CCM’s quality can be controlled in real time, and it is convenient for the
maintenance personnel to analyze the CCM’s measurement results. The problem
areas of the casting machine equipment can also be found. If these problems
doesn’t be found in time, it will cause the bad quality of CCM’s products,
the steel breakout in pouring process, surface and internal cracks and
centerline segregation.



The measurement of the strand condition monitor



Roll gap value：

By measuring the distance between a series of inner arc guide rolls and
outer arc guide rolls on the CCM’s roller bed.

It can be used to set the correct roll gap spacing for each pair of guide
rolls in the slab caster.



Outer arc guide roller to arc：

By measuring the deviation between the position of the CCM’s outer arc
guide roll and the two adjacent guide rolls and the CCM’s original
position, we can obtain the arc condition of the outer arc guided roller.



Guided roller rotation：

It is possible to know whether each guided roller can rotate freely by
measuring.



Water spray pressure：

The operation of the water spray cooling system can be judged by measuring
the situation of secondary cooling water spray at different positions of
CCM's width direction. Then we can accurately locate whether the water spray
at a certain point is normal.
