【Abstract】 The mechanism of Longitudinal crack formation has been studied in detail in the round ingot of low alloy structural steel from aspects of temperature, compositions and fluid flow. At the same time the effective measures of controlling the longitudinal cracks in the round ingot are put forward, which are more benefitial to quality cost reduction.更多还原
