The original mouth of the low -pressure forging aluminum alloy wheel heart cracking

The heart cracks of low -pressure forging aluminum alloy wheels are mainly generated in the part of the stress concentration, or the cracks caused by the unevenness of the stress due to unevenness, or the liquid condensation at the lift pipe. Cracks are generally divided into two types: cold and hot cracks.
Cold cracks refer to the cracks formed by the alloy when the temperature of the solid phase line is lower than its solid phase line. In layman’s speaking, cold cracks are produced by the forging stress on the casting when the casting is cooled to the low temperature. Cold cracks mostly appear in the appearance of the casting, and the crack appearance has slight oxidation: and the thermal cracks think that it is produced during the alloy condensation process. Because of the heat transfer effect of the wall, the casting is always condensed from the beginning. When a large number of branches appear in the casting and are connected into a complete fan bone, the casting will appear solid tightening (often expressed in line tightening). However, there is still a layer of liquid metal film (liquid film) that has not yet been condensed between Zhi crystals. Stress. When the tightening of the branch crystal is hindered, it cannot be freely tightened or the role of tension will occur, and the stress will occur. At this time, the liquid film between the chinensis will be stretched and deformed. When the tensile stress exceeds the strength limit of the liquid membrane, the chinetic crystal will be pulled open. However, there are still some liquid metals around the cracking part. If the liquid film is pulled open very slowly, there is enough liquid around and flowing in time. “The casting does not have hot cracks. If the crack cannot be “healed” from the beginning, the casting will appear hot cracks. The appearance of the hot crack is strongly oxidized, showing a dark or black without metallic luster.
