| Abstract: | The technology of the solid side dam used in strip casting process is described, the damage reason of the side dam is analyzed and the way to prolong the operating life of the side dam is proposed. Two types of the side dams made of refractory alone and combined materials are investigated and the material of the side dam is studied. The calcium silicate side dam is the best material in combination of properties and more suit- able for the microstructure of continuously roll-cast.The thermal analysis and thermal stress analysis of the side dams are carried out by ANSYS finite analysis software.The results show that the combined type side dam made of 6CaO· 6SiO2· H2O and BN has a better process stability and operating life. |
