Covering powder

                        Introduction

                         

                        Our company has developed and manufactured a series of hollow grained covering powder products combining with production demands of various types of steel to meet the continuous casting process.

                        Covering powder (or covering flux/powder, protective agent) are classified as high-carbon, medium carbon, low carbon and carbon-free by the content of carbon. In addition, it can be divided into alkalinity product ,acid product and high alkalinity by PH value.

                        Covering powder has good diffusion effect and strong thermal insulation performance without crusting and polluting molten steel, which is well received by clients. The choice of covering agent as per specific steel making conditions.

                         

                         The function of covering powder:

                         

                        (1) It plays the important role in good heat preservation.
                        (2) Absorbing inclusions and purifying molten steel.
                        (3) Preventing secondary oxidation of molten steel effectively.

                         Characteristics of covering powder

                         

                        Low carbon cover powder

                        Applicable steel: carbon content in molten steel C0.08

                        Good diffusion effect, no congeal, purifying molten steel, prevent molten steel from secondary oxidation. Eliminate the potential carbon pick-up.

                        Medium carbon cover powder

                        Applicable steel: carbon content in molten steel C0.25

                        Good diffusion effect, no congeal, purifying molten steel, prevent molten steel from secondary oxidation. Good heat preservation.

                        High carbon cover powder

                        Applicable steel: carbon content in molten steel C0.45

                        Good diffusion effect, no congeal, purifying molten steel, prevent molten steel from secondary oxidation. Good heat preservation.

                        Carbon free cover powder

                        Applicable steel: ultra low carbon steel

                        Good diffusion effect, no congeal, purifying molten steel, prevent molten steel from secondary oxidation., control carbon pick-up

                        High alkalinity cover powder

                        Applicable steel: suitable for steels with no special requirements for Al2O3 content.

                        Strong adsorption capacity, Good diffusion effect, no congeal, purifying molten steel, prevent molten steel from secondary oxidation.

                        Acid cover powder

                        Applicable steel: High heat preservation requirements, high level of cleanliness
                        Strong adsorption capacity, Good diffusion effect, no congeal, purifying molten steel, prevent molten steel from secondary oxidation.
