With the development of the steelmaking industry, there are numerous types and sizes of steel ladles in the domestic steelmaking industry. Currently, common arrangements for breathable bricks at the bottom of steel ladles include single breathable brick single blowing, radially symmetrical double blowing, radially asymmetrical double blowing, and vertical double blowing.
1 Single breathable brick blowing
Steel ladles over 100 tons mostly use single or double breathable bricks for spraying, and eccentric spraying is better than central spraying. The optimal position of the blowing holes is between 1/3 and 2/3. As shown in the figure, single breathable brick (holes 1, 2, 3) sprays argon gas.
2 Radially symmetrical double blowing
Distributed on the same diameter at the bottom of the ladle, and two breathable bricks symmetrical about the center of the ladle bottom are blown simultaneously (holes 1 and 6, holes 2 and 5, holes 3 and 4).
3 Radially asymmetrical double blowing
Two breathable bricks distributed on the same diameter at the bottom of the ladle but asymmetrically double-blown (holes 1 and 4, holes 1 and 6, holes 2 and 6).
4 Vertical double blowing
Double blowing of two breathable bricks whose diameters are perpendicular to each other (hole 6 respectively with holes 1, 2, 3; hole 8 respectively with holes 1, 2, 3 double blowing).
Conclusion
No matter which arrangement method is used, it is necessary to comprehensively consider the actual situation, mainly by changing the amount of gas sent, measuring the mixing time, and selecting the optimal breathable brick arrangement scheme. Luoyang Kechuang New Materials Co., Ltd., focusing on the research, development, production, and sales of breathable bricks for 22 years, is a professional breathable brick manufacturer. Welcome to inquire.
