• Directionality in Hot Rolled Steel Plates (Report 1)

抄録

The study is concerning of the directionality of heavy mild steel steel plates. Micro tension test pieces were used in this test. The test pieces were taken from the three directions, i.e. the direction in which steel plates were rolled (lengthwise), their rectangular direction (crosswise), and the direction of the perpendicular to the plate surface (T direction). The steel plates used in this test were all killed steel. Some steel plates used in this test were applied controlled treatment, but some were not. The range of the thickness of the plates is 30-65mm.<BR>The results of the test is follows.<BR>(1) The yield point lowers in order-lengthwise, crosswise, and T direction.<BR>(2) The tensile strength also drops in order-lengthwise, crosswise, and T direction. The difference of the tensile strength between lengthwise and crosswise is under 1kg/mm² and that between lengthwise and T direction is 1-6kg/mm².<BR>(3) Concerning the percentage elongation, lengthwise is the highest. The percentage elongation of the crosswise is 0-3% lower than the lengthwise. The percentage elongation of the T direction drops as the reduction ratio raise. When the reduction ratio raise to the amount of 16, the percentage elongation of the T direction lower to 10%.<BR>(4) Concerning the reduction of area, lengthwise is the highest. The reduction of area of crosswise is about 5-10% lower than lengthwise. The reduction of area of the T direction drops hastily as the reduction ratio grows. When the reduction ratio grows to the amount of 16, the reduction of area of the T direction drops to about 20%. The Ductility of the T direction is remarkably low of the steel plates that were applied controlled treatment than those that were not.
