The utility model provides a heating furnace with dual charging roller ways. An auxiliary roller way is arranged in parallel at one side of a charging roller way connected with a continuous casting ejection roller way; and two transversely-moving trolleys are arranged between the charging roller way and the auxiliary roller way. When the charging roller way connected with the continuous casting ejection roller way is in charging, cold blanks can be charged on the auxiliary roller way; the charging and discharging of cold and hot blanks cannot be interfered mutually; the auxiliary roller way can stock materials in large quantities under the condition that the discharging of the hot blanks is not affected and can transversely move the blanks onto the charging roller way through the transverse-moving trolleys, thereby greatly improving the charging capacity; when a rolling plan is adjusted, steel blanks on the charging roller way can be transversely moved onto the auxiliary roller way, so as to shorten the charging and discharging time of the steel blanks, thereby increasing the stock quantity, meeting the charging demands of a steel rolling production line, preventing a rolling mill from stopping and waiting for the materials, solving the problems of conflicting contradiction between continuous casting and steel rolling rhythms and difficult plan adjusting of thermal blanks charging and delivering, and guaranteeing stable steel rolling production.
