Casting powder

Casting powder (also known as “mold flux”) is the heart of continuous casting, which plays a key role in continuous casting process. Excellent casting powder performance could greatly improve surface quality of casting blank and casting speed.

Multiple kinds of calcium metasilicate and necessary raw materials mixed together per client’s specific steel making demands to produce casting powder.

Casting Trading company provide not just casting powder for clients, also customized design based on clients’ actual steel making demands. Over 30 years of casting powder production experience committed us to provide professional technical support & solutions for all our clients in domestic and overseas.

Five major effects of casting powder:

(1)Good lubrication for casting billets to smoothly pulled out of the crystallizer.
(2) Good insulation capacity and good diffused ability
(3) Heat transfer control, improve the heat conduction rate and uniformity.
(4) Prevent molten steel from secondary oxidation
(5)Absorb the inclusions to improve the cleanliness of the steel

Insulation cover powder

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.

Ladle filler sand

To solve the defect of low automatic pouring rate, excessive oxygen burning and interruption in continuous casting process, our company has developed and produced a series of aluminum and chromium ladle chromium-containing diversion sand(or stuffing sand) products (National Invention Patent).

This kind of chromium contained diversion sand is used in ladle nozzle, the main chemical components are Cr2O3,SiO2,Al2O3 and C.

The major characteristic for Ladle filler sand:

The series of products have advantages of good flowing property, high refractoriness and resistance to steel water erosion permeates, which could form appropriate sintered layer thickness, improve automatic flow ratio from ladle, reduce oxygen blowing and drainage , enhance the quality of steel blank and assure of smooth conduction for continuous process.
