Abstract: The average life of the alumina cement prefabricated beam in front and back of the burner of the sintering machine was only two months at Panzhihua Iron & Steel Co. To solve the problem,the beam of low-cement in combination with high alumina castable refractory has been developed and the erection method has been improved.Consequently,the service life is raised to over 6 months,with the maximum life up to 16 months.
