Meanwhile, on the afternoon of September 11, Zhang Boming, Huang Tianyou, Gong Jimin and Ying Zhongtang, experts from the expert committee of China Foundry Association, visited the fused ceramic sand factory of Lianxin Foundry Group.
In the process of casting at high temperature, due to the thermal expansion of molding sand, it is easy to cause a small change in the size of molding sand, thus affecting the dimensional accuracy, appearance and performance of castings. At the same time, if the thermal expansion coefficient of molding sand is too large, it will cause sand inclusion, scab, rat tail and other casting defects. All kinds of factors make foundry enterprises more cautious in choosing molding sand, not only considering the coefficient of thermal expansion of molding sand, but also considering the cost of molding sand.
Investment sand is mainly divided into quartz sand and special sand according to the composition of minerals. Quartz sand is commonly known as silica sand. Let's understand the difference between silica sand and non silica sand. The main mineral composition of silica sand is quartz and the main chemical composition is SiO2.
