Temperature measurer selects temperature sensors of high precision, and designs cooling and protective device to temperature measurer, it is fully sealed
To reach constant temperature and humidity and every the working environment of magnetic.
The reason of selecting the last one fan-shaped section to export thermometric are as follows: the last one fan-shaped section is in the end in two cold water spray areas
Position wants much friendly for the relatively entire two cold water sprays closed environment of environment, and environmental disturbances are smaller, it is easier to which it is accurate to obtain
Temperature measurement data.
The reason of selecting straightening section thermometric are as follows: there are brittle temperature ranges for steel grade, when it is in brittleness section, permission
The contraction percentage of area is smaller, and yield strength is small, and casts combined stress of the stream in tension leveling segment by biggish mechanical stress and thermal stress,
Just probably it is more than yield strength to make the raw internal and surface quality problems of casting miscarriage, therefore monitors the table of straightening section in real time
Face temperature, judges whether it falls in the brittle temperature range of corresponding steel grade and be just particularly important.The cooling and protective device
