Research and Application of Environment-friendly Core Making Technology for Aluminum Alloy Subframe
In view of the difficulties such as large volume of resin sand core for integral aluminum alloy subframe,heavy smoke during pouring and serious environmental pollution,the inorganic sand core process was developed.Through the selection of core making equipment and the horizontal parting mode of core shooting,the core sand composition ratio,sand mixing time,core box temperature,storage temperature and humidity are further tested and studied.The test results show that the sand core is more easily formed by the non-mechanism core process in the casting of the integral subframe.In the pouring process,there is not only no obvious thermal decomposition products and no condensates,but also easy to collapse and have good sand removal effect and low gas emission,which can effectively reduce porosity defects,improve product quality and promote the development of green and low-carbon casting technology.
