[0002] Ironmaking is the process of extracting metallic iron from iron-containing minerals (mainly iron oxides). There are mainly blast furnace method, direct reduction method, molten reduction method, and plasma method. From a metallurgical point of view, ironmaking is the reverse behavior of iron rusting and gradual mineralization. Simply put, pure iron is reduced from iron-containing compounds. In actual production, pure iron does not exist, and what is obtained is an iron-carbon alloy.

[0003] The prior art has the following problems: the air circulation for ironmaking must be controlled at a certain temperature. If the temperature inside the furnace is too high, it will cause excessive pressure inside the furnace, which poses a certain risk. At this time, a certain amount of cold air needs to be introduced to achieve temperature control on the one hand and to replace the cold and hot air flows on the other hand. At that time, there was a lack of an autonomously controlled air circulation temperature control device for ironmaking, which was not conducive to actual temperature control use.

[0009] Preferably, through the pushing of the pushing spring, the blocking sealing disk at the bottom of the blocking sliding rod is pressed and sealed on the blocking ring platform, and the temperature sensing tube is filled with thermosensitive gas.

[0010] Preferably, the supporting shaft is rotatably connected to the ironmaking air supply ball pipe via a bearing seat, and in an initial state, the ball head slot is not directly opposite to the ironmaking air supply straight pipe and is in a closed structure.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: in the initial state of the utility model, the supporting shaft is rotatably connected to the ironmaking air delivery ball tube through the bearing seat, at this time, the end guide arm slides through the side end platform with a hole, the push spring and the bottom tightening platform are located below the side end platform with a hole, and the two ends of the push spring are respectively in contact with the bottom tightening platform and the side end platform with a hole, and through the push of the push spring, the sealing disk at the bottom of the blocking slide rod is pressed and sealed on the sealing ring platform, the temperature sensing tube is filled with thermosensitive gas, and at the same time, the ball head is passed through the sealing ring. The groove is not directly opposite to the straight air supply pipe for ironmaking and is in a closed structure. In actual use, the temperature sensing tube is inserted into the ironmaking chamber. When the temperature rises, the gas in the temperature sensing tube expands, and the sealing disk will be pushed up. At this time, the blocking slide rod drives the gripping tube to move upward. Since the gripping tube sleeve is arranged on the outside of the supporting shaft rod and the guiding convex slide head is inserted in the spiral sliding groove, through the cooperation of the above structure, the supporting shaft rod rotates at this time, and the ball head groove is directly opposite to the straight air supply pipe for ironmaking and is in an open structure, thereby realizing air supply adjustment.
