The side dam technology for twin roll strip casting was discussed.The effect of preheating temperature,material and design of side dam on the process stability and surface quality of products was analyzed.The wear and erosion of side dam for different steel grades were described.Two types of side dam designs,namely integral type and combined type,were used in the experiment,and the suitable position of side dam was determined by experiment.The results show that the combined side dam is better than the integral one in process stability and long service life.The temperature fields and thermal stress fields in side dam during strip casting were analyzed using the finite element analysis software,and the causes of side dam cracking were explained.
