Paper Title:
Study on the Technological Adaptability of the Reclaimed Sand Applied in the Chemical Bonded Sand
  Abstract

The technological adaptability of the reclaimed sand applied in the chemical bonded sand was studied in this paper. The reclaimed sand can be obtained by the process of high-temperature baking followed by mechanical reclamation and separation of micro-powder. The reclaimed green sand which containing different types of chemical bonded core sand were applied in corresponding system of chemical bonded sand process, such as the process of cold-box sand, hot-box sand, precoated sand, sodium silicate sand and self-hardening sand. Through technological experiments, it can be found that the tensile strength value of the precoated sand and sodium silicate sand which were prepared using reclaimed sand can be equal or slightly higher than that of prepared using the base sand, the tensile strength value of the cold-box sand, the hot-box sand and the self-hardening sand which was prepared using the reclaimed sand are lower than that of prepared using the base sand. Compared with the chemical bonded sand requirements in the foundry practice, the cold-box sand, the hot-box sand, the precoated sand which was prepared using the reclaimed sand can still meet the casting process needs, but the self-hardening sand which was prepared using the reclaimed sand cannot meet the casting process needs.
