Reducing Energy Consumption and Costs
In the hot rolling process, since rolling is carried out above the recrystallization temperature of aluminum alloy, the aluminum alloy exhibits high plasticity and low deformation resistance at this time. This significantly reduces the energy consumption required to deform the metal and notably lowers the energy consumption during the production process. Meanwhile, the lower deformation resistance also relatively reduces the requirements for rolling equipment, saving equipment cost investment to a certain extent and ultimately decreasing the overall production cost of aluminum alloy explosion-proof balls.
Enhancing Material Properties
-
Grain refinement: It can break the coarse grains of aluminum alloy in the as-cast state, thereby refining the grains. Refined grains make the organizational structure of aluminum alloy more uniform and dense, which improves the comprehensive properties of the material such as strength and toughness, ensuring that the aluminum alloy explosion-proof ball is less likely to be damaged when withstanding explosion impacts.
-
Crack healing and defect elimination: The high-temperature environment helps heal the tiny cracks existing in the aluminum alloy, and can reduce or eliminate casting defects such as pores and looseness. It transforms the original as-cast structure into a deformed structure, which greatly improves the processing performance and service performance of the aluminum alloy and enhances the reliability of the aluminum alloy explosion-proof ball.
Improving Production Efficiency
Hot rolling usually adopts large ingots for rolling with large reduction. This method can quickly change the shape and size of the aluminum alloy, reduce the number of rolling passes, accelerate the production rhythm, and thus significantly improve production efficiency, meeting the demand for mass production of aluminum alloy explosion-proof balls. At the same time, the aluminum alloy has good plasticity and low deformation resistance during hot rolling, which creates favorable conditions for increasing the rolling speed and realizing the continuity and automation of the rolling process, further improving the production efficiency and stability.
Ensuring Product Quality
Hot rolling can ensure the uniform thickness of the aluminum alloy explosion-proof ball material, which is crucial for the uniform dispersion and absorption of explosion energy in its actual use. Uniform thickness can avoid stress concentration caused by local thickness differences, thereby exerting the explosion-proof function more effectively. Moreover, the aluminum alloy after hot rolling has advantages in oxidation: it has a relatively uniform oxidation color and good surface quality, which enables it to better adapt to various complex service environments and extend the service life of the aluminum alloy explosion-proof ball.
