A kind of breathable brick with two-way inclined slit and safety warning device and its preparation method

Abstract

The invention relates to an air brick with bidirectional inclination slits and a safety pre-warning device and a preparing method of the air brick. The outer conical face of a brick inner core of the air brick is provided with a white steel inner shell, and the inner conical face of a brick outer sleeve is provided with a white steel outer shell. A brick ring sleeve is arranged between the white steel inner shell and the white steel outer shell. The safety pre-warning detection device is arranged at the center of the brick inner core. An argon chamber is arranged at the lower portion of the brick inner core, a gas-leakage-preventing bottom cover is arranged on the upper faces of the argon chamber and the brick ring sleeve. An argon blowing opening communicating with the argon chamber is formed in the gas-leakage-preventing bottom cover. The multiple inner circle slits and the outer circle slits are evenly distributed in the circumference of the interior of the brick inner core to communicate with the argon chamber. The radial inclination of the inner circle slits and the outer circle slits towards the cone central axis ranges from 2 degrees to 4 degrees, and meanwhile the inner circle slits and the outer circle slits incline by 1 degree to 3 degrees along the cone busbar. The air brick is provided with the bidirectional inclination and the safety pre-warning detection device, the air brick blows argon so that molten steel can generate circulation and turbulence processes in a steel ladle, various alloys, deoxidizing agents, desulfurizing agents and the like added in the molten steel can be rapidly melted, and the molten steel can be stirred more evenly.

Description

technical field [0001] The invention relates to the field of kiln refractory materials, in particular to a ventilating brick with bidirectional inclination slits and a safety warning device and a preparation method thereof. Background technique [0002] At present, the argon blowing technology at the bottom of the ladle has been applied for decades, and has also made effective progress in the refining steel technology, which has improved the quality of steel products, but compared with foreign refining steel technology, there is still a large gap. The gap is that the quality of foreign finished steel products is still far beyond the domestic level, and domestic steel materials for some important equipment accessories cannot meet the quality requirements, and imported steel materials must be used. The gap in steel quality is mainly reflected in the crystal structure of steel and the uniformity of steel composition. The main reason affecting the quality of steel is the defects...

Problems solved by technology

However, first, the air brick alarm of this structure is pre-embedded in the brick body, and it cannot be confirmed that the air brick is 100% pre-embedded with the alarm during use, which causes a psychological burden to the installer; second, the above-mentioned alarm There are square logos and luminous bodies in the middle, and they are made of high-temperature luminous materials. These not only greatly increase the cost of the brick body, but also have the problem of whether the safety of the luminous materials can be ensured during use.
