Embodiment 1
[0025] like figure 1 Shown is a slag blocking ball for a converter. The slag blocking ball includes a ball base 1 and a handle 3 connected to the ball base. The surface of the ball base 1 is coated with a gas generating layer 2 with a thickness of 1-50 cm.
[0026] A circle of gas generating material is coated on the surface of the ball matrix to form a gas generating layer, and the gas generating layer is made of CaCO 3 , MgCO 3 、BaCO 3 1. Calcium aluminate cement is mixed and coated according to the proportion of 30%:30%:30%:10%. The diameter of the ball base is 30cm, and the thickness of the gas generating material is 10cm. The slag blocking ball is used in conjunction with the sliding plate slag blocking technology to block slag. When the tapping end is critical for 1 minute, the slag blocking small ball of the present invention is thrown into the vicinity of the tapping hole by the slag blocking trolley. Under high temperature conditions, the slag blocking The ball pro...
Embodiment 2
[0028] like figure 1 Shown is a slag blocking ball for a converter. The slag blocking ball includes a ball base 1 and a handle 3 connected to the ball base. The surface of the ball base 1 is coated with a gas generating layer 2 with a thickness of 1-50 cm.
[0029] A circle of gas generating material is coated on the surface of the ball matrix to form a gas generating layer, and the gas generating layer is made of CaCO 3 , MgCO 3 、BaCO 3 , Aluminate silicate cement is mixed and coated according to the proportion of 30%:40%:20%:10%, the diameter of the ball base is 35cm, and the thickness of the gas generating material is 15cm. Utilize the slag blocking ball of the present invention to block slag, and when the tapping criticality ends for 1 minute, use the slag blocking trolley to throw the slag blocking ball into the vicinity of the tapping hole, and in a high temperature state, gas is generated, which has the effect of suppressing the eddy current Function, the generated g...
Embodiment 3
[0031] like figure 1 Shown is a slag blocking ball for a converter. The slag blocking ball includes a ball base 1 and a handle 3 connected to the ball base. The surface of the ball base 1 is coated with a gas generating layer 2 with a thickness of 1-50 cm.
[0032] A circle of gas generating material is coated on the surface of the ball matrix to form a gas generating layer, and the gas generating layer is made of CaCO 3 , MgCO 3 、BaCO 3 , Aluminate silicate cement is mixed and coated according to the proportion of 40%:40%:10%:10%, the diameter of the ball base is 40cm, and the thickness of the gas generating material is 20cm. Utilize the slag blocking ball of the present invention to block slag, and when the tapping criticality ends for 1 minute, use the slag blocking trolley to throw the slag blocking ball into the vicinity of the tapping hole, and in a high temperature state, gas is generated, which has the effect of suppressing the eddy current Function, the generated g...
