Document Type and Number:
Japanese Patent JP6965988
Kind Code:
B2
Abstract:
A seamless steel pipe heat-treatment-finishing-treatment continuous facility (1) includes: a heat treatment apparatus (10); a steel pipe inspection apparatus (30) which performs a test for a surface defect and/or an inner defect of the seamless steel pipe, the steel pipe inspection apparatus (30) being disposed downstream of the heat treatment apparatus (10); a main transfer mechanism (100) which forms a main transfer path MT for transferring the seamless steel pipe, discharged from the heat treatment apparatus (10), to the steel pipe inspection apparatus (30) disposed downstream of the heat treatment apparatus (10); and a first forced steel pipe-temperature reduction apparatus (20A) which forcibly reduces a temperature of the seamless steel pipe on the main transfer path MT, the first forced steel pipe-temperature reduction apparatus (20A) being disposed on the main transfer path MT at a position downstream of the heat treatment apparatus (10) and upstream of the steel pipe inspection apparatus (30).
