Normally, gas blowing parts with porous bricks or gas blowing parts with slits are shown in Figure 1a.
As shown in Figure 1b, the element brick 1 is hardened with monolithic refractory material 2, etc. and a metal case 3 is attached to it, or as shown in Figure 1b, the element brick 1 is directly fitted into the metal case 3. I have something to wear. However, in such a configuration, if the element brick 1 is a right circular cylinder or a rectangular parallelepiped, or if its taper is small, the element brick may jump out to the working surface side due to the gas pressure on the gas header side. This causes accidents such as steel leakage. In particular, as shown in Fig. 1b, even if the gas blowing part has mortar joints 4, the mortar disappears (for example, the mortar is crushed by the impact during operation, and the gas blowing part has mortar joints 4). There is a good chance that the bricks will pop out due to reasons such as gas flowing in, pushing the mortar out of the gas injection area and creating voids in the mortar joints, or elongation of the metal case during hot heating. To deal with this, conventional gas blowing bodies used in ladles, converters, etc. are made by binding the ventilation element bricks 1 with wires 5 to form an appropriate wire ring, as shown in Figure 2a. The ring is embedded in the monolithic refractory 2, or as shown in Fig. 2b, the stepped element brick 1 is embedded in the monolithic refractory 2 to prevent the element brick 1 from flying out. .
しかし、かかる構成において、エレメントれん
が１はれんが相互間の連結によつて行われている
ため、飛び出し防止効果の面で十分ではなかつ
