Slag Ball

How to choose the slag blocking ball?

The correct choice of slag ball can effectively improve the purity of the steel. The density of the slag blocking ball is particularly important to the slag blocking effect, if the density of the slag blocking ball is too small, it will float on the surface of the steel in the process of blocking slag and cannot play a slag blocking effect. If the density is too large, it will cause the outlet to be blocked prematurely, thus prolonging the time for steel production. Due to its light top and heavy bottom structure and the basic principle of automatic positioning of the gyroscopic shape, the guide bar sunk deep into the steel will automatically and accurately pull the gyroscopic slag blocking device to the steel outlet through the traction guidance of the steel flowing to the outlet, thus avoiding the phenomenon of drifting or being stuck by the slag and not in place. The gyro-shaped part is suspended on the interface between the steel and slag, when the steel flows out, the gyro-shaped part blocks the steel outlet in time, thus preventing the slag from flowing into the ladle. Because of the groove on the gyro body, to achieve the inhibition of eddy flow, and when the slag stopper body blocked the steel outlet, the residual steel can still flow through the groove into the ladle, so improve the steel collection rate.

What Is Slag Ball?

Slag blocking ball is a kind of spherical or gyroscopic refractory material, which is widely used to block the floating slag from entering the steel in the process of steel making, and greatly improve the purity of steel and steel quality. The working temperature of the slag-blocking ball is 1770℃-2000℃, and its chemical composition is MGO+Al2O3. most of the slag-blocking balls are 150 mm-300 mm in diameter and have grooves on the surface, which can effectively block the slag at the water outlet.

What is Advantages Of Slag Blocking Ball?

1. Simple operation.

During the steel making process, block the steel outlet with the slag blocking ball, and the slag will fall off automatically when pouring the steel.

2. Safety and environmental protection.

Slag blocking ball can ensure that the steel wire faucet not fire, not smoke, not overflow, safe and environmentally friendly.

3.A variety of models and sizes of slag blocking balls can be selected: diameter: 150mm-300mm

What is the application of Slag Blocking Ball?

To reduce slag carryover from the BOF.
Slag balls are made of light burnt magnesia, magnesite powders and shaped through presses. Slag balls are mainly used for the slag splashing, which can effectively improve the performance of BOF.
Slag Stopping Balls are made of light burnt magnesia, magnesite powders and shaped through presses. Slag balls are mainly used for the slag splashing, which can effectively improve the performance of BOF.

What is PS Ball ?

PS Ball is environment-friendly product with stable molecular structure from molten slag generated a steelmaking process at steel melting shop. The reason why PS Ball processed with SAT is structurally stabilized Being processed with SAT, ions dissociated in ion form can be as stable oxide compound in Spinel Structure. Spinel Structure with general chemical formula AB2O4 is octahedron shaped structure as illustration in which oxygen atom is almost filled with cube clisepacked packing, that is the structure with B atom surrounding 6 oxygen atoms in octahedron and with A atom surrounding 4 oxygen atoms.
