| description | ObjectivesDiamond wire saw cutting, being environmentally friendly and unaffected by water depth, structure material, shape, or size, has become the preferred method for dismantling large oceanic structures. However, when cutting jackets above the water surface, the elevated temperatures in the cutting zone can lead to excessive wear on the wire saw and even result in cutting failure. To address this issue, this paper integrates theoretical, simulation, and experimental analyses to examine the impact of various cooling conditions on cutting zone temperature and tool wear. Furthermore, it identifies an optimal cooling method for the dismantling process of jackets using diamond wire saws on the sea surface.MethodsFirst, based on the principles of thermal conductivity, a theoretical model of the temperature field in the cutting zone of diamond grains is developed to analyze the influence of cutting and media parameters on heat generation. Next, using AdvantEdge simulation software, a kinetic simulation model of diamond grit cutting reinforced concrete materials is established under various working conditions, including dry cutting, low-temperature air cooling, high-pressure water cooling, liquid nitrogen cooling, and low-temperature spray cooling. The temperature rise in the cutting zones under different cooling methods is analyzed. Finally, experimental cutting tests using diamond wire saws on reinforced concrete material workpieces are conducted to investigate the failure behavior and wear rate of the wire saws under different cooling conditions. The optimal cooling method is then identified and validates the simulation results.Results(1) According to the theoretical model of the temperature field in the cutting zone, the surface temperature increases with higher cutting parameters such as feed speed, cutting speed, and cutting time, while it decreases with the increase of medium parameters such as specific heat capacity and thermal conductivity. (2) The cutting simulation study indicates that under dry cutting conditions, the temperature in the cutting zone exceeds the diamond carbonization threshold, significantly compromising the cutting performance of the wire saw. In contrast, all four cooling methods maintain the cutting zone temperature below the diamond carbonization threshold, with low-temperature spray cooling demonstrating the most effective reduction in tool wear. (3) By measuring changes in the outer diameter of the beads on the wire saw, the lowest wear rate is observed under low-temperature spray cooling, which further validates the findings of the cutting simulation study. (4) Scanning electron microscope analysis of the worn diamond abrasive grains reveals four distinct behaviors of wear: intact abrasive grains, abrasive edge wear, surface fragmentation, and abrasive grain detachment. (5) Compared to dry cutting, low-temperature spray cooling increases the percentage of intact abrasive grains from 18% to 31% and reduces the abrasive grain detachment rate from 39% to 24%, thereby significantly enhancing cutting efficiency and extending the service life during diamond wire saw cutting of reinforced concrete materials.ConclusionsWhen dismantling platform structures on the sea surface using diamond wire saws, low-temperature spray cooling is prioritized due to its minimal temperature rise in the cutting zone and the lowest bead wear rate. This approach significantly enhances cutting efficiency and extends the service life of the diamond wire saw. |
