Title:
COOLING CONTROL METHOD OF STEEL PLATE IN HOT ROLLING
Document Type and Number:
Japanese Patent JPH08103809
Kind Code:
A
Abstract:

PURPOSE: To obtain the steel plate having targeted and uniform mechanical property without use of a transformation measurement device.

CONSTITUTION: Transforming heat generation of steel plate is calculated before cooling start of steel plate. A finish temp. thermometer 5 and plate thickness gage 6 are arranged at the outlet of a finishing mill 2, a temp. and plate thickness of a steel plate 1 are measured in sampling. These signals are fetched in a computer 8 and are followed over a whole hot line table. In deciding the cooling pattern of cooling bank 4, 4... so that the forecast temp. record of sampling point follows target temp. record, sampling position, a temp. of sampling point as well as transforming heat generation are used.
