The invention discloses a compound steel belt with high temperature resistance and corrosion resistance. The compound steel belt comprises an inner layer. A partition layer is fixedly connected with one side of the inner layer. A middle layer is fixedly connected with the side, away from the inner layer, of the partition layer. A buffer belt is fixedly connected with the side, away from the partition layer, of the middle layer. An outer layer is fixedly connected with one side of the buffer belt. A thin film layer is fixedly connected with the side, away from the partition layer, of the inner layer. A corrugated pipe strip is arranged on the side, away from the inner layer, of the thin film layer. An elastic air bag belt, a flexible strip, a graphite layer and a carbon steel layer are arranged, the graphite layer can absorb alkaline or acid substances in corrosive liquid, and therefore the corrosion strength can be reduced; a polyethylene layer which is arranged can play a role in corrosion resistance; a fiber strip and a fiber layer are arranged and can achieve the effects of heat preservation and flame retardance; and a nonwoven fabric layer and a network cloth layer are arranged, the sufficient flame-retardant and high-temperature-resistant effects can be achieved, and therefore the high temperature resistance and the corrosion resistance of the compound steel belt are improved.
