Mechanical Properties

Effect on Strength:
Pure molten iron can ensure that the steel plate has more stable and reliable strength. If there are too many impurities in the molten iron, such as a relatively high content of sulfur (S) and phosphorus (P), brittle phases will form inside the steel plate. These brittle phases are prone to cracks when subjected to external forces, leading to a decrease in the actual load - bearing capacity of the steel plate. In contrast, pure molten iron helps to produce steel plates that meet the standard strength requirements. For example, for BV - AH36 shipbuilding steel plates, the yield strength is not less than 355MPa. High - purity molten iron can ensure that the steel plate can effectively support the self - weight of the ship, the weight of the cargo, and withstand various external forces such as seawater pressure and wave impact in actual use, meeting the design strength standards.

Effect on Toughness:
The purity of molten iron is crucial for the toughness of the steel plate. Impurity elements will reduce the toughness of the steel plate, making it more prone to brittle fracture when the steel plate is subjected to impact or dynamic loads (such as wave impact and ship vibration). Pure molten iron can reduce the influence of these harmful impurities and endow the steel plate with good toughness. For example, in the case of ship collisions and groundings, the steel plate produced from high - purity molten iron can absorb more energy and avoid sudden fracture, thus ensuring the structural integrity of the ship.

Welding Performance
If the molten iron has a high purity, the produced steel plate will have better welding performance. Sulfur (S) and phosphorus (P) are impurity elements that have a relatively large impact on welding performance. A high content of sulfur is prone to cause hot cracks during the welding process because sulfur will form low - melting - point sulfides with iron. During the welding thermal cycle, these sulfides will melt at the grain boundaries, resulting in cracks. Pure molten iron can reduce the sulfur content and reduce the possibility of hot cracks. At the same time, a low phosphorus content also helps to prevent cold cracks in the heat - affected zone during welding. Good welding performance enables the steel plate to be conveniently welded and assembled during the shipbuilding process, ensuring the quality of the welded joint and the integrity and reliability of the ship structure.
