In summary, the causes and preventive measures of ABS grade A steel tensile crack are as follows:
(1) the high content of elements with low melting point in the ABS grade A steel directly leads to the occurrence of tensile cracks. At the present stage, if it cannot be eliminated in the steel-making process, the content of elements with low melting point in the ABS grade A steel plate in molten iron should be reduced as far as possible;
(2) in order to avoid the influence of Cu, an appropriate amount of Ni can be added to the ABS grade A steel when necessary. Katalor is currently controlled by 0.010%~0.025%.
(3) the content of P.S in the ABS grade A steel plate should be as low as possible, and the Nb should also be controlled reasonably, which should be controlled at 0.010%~0.020%;
(4) the temperature of the preheating section of the ABS grade A steel should be as high as possible, and the residence time of the steel billet should be shortened at the same time;
Strictly speaking, the ABS grade A steel plate tensile crack is not absolutely eliminated, we just found the important factors affecting its production and control it to a certain extent.
