Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting auxiliary equipment, in particular to a slag stopper for a converter tapping port. Background Art

[0002] Converter smelting uses molten iron, scrap steel, and ferroalloys as the main raw materials. The steelmaking process is completed in the converter without the help of external energy. The heat is generated by the physical heat of the molten iron itself and the chemical reactions between the components of the molten iron.

[0003] Converter smelting is an oxidation reaction process. The introduction of oxygen reacts with the elements in the molten iron, producing a large amount of thick smoke. During the blowing process, the thick smoke will overflow through the steel tapping port, causing environmental pollution. In addition, a violent carbon-oxygen reaction occurs during the converter smelting process, resulting in splashing. The high-temperature slag in the furnace is ejected through the steel tapping port, polluting the environment and even causing personal injury. Utility Model Content

[0018] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0019] See Figure 1-3As shown, a slag stopper for a converter steel tapping port of the present invention comprises a plug body 1. The plug body 1 is a tapered structure that is wide at the top and narrow at the bottom. A connecting rod 4 is provided at the upper end of the plug body 1. A handle 5 vertically connected to the connecting rod 4 is provided on the connecting rod 4. Symmetrically arranged sliders 3 are provided on both sides of the upper end of the plug body 1. The sliders 3 are slidably connected to the plug body 1. A locking piece is provided between the slider 3 and the plug body 1. A locking assembly 2 for preventing the plug body 1 from moving is provided on the slider 3. After the converter taps steel, adjust the tilting angle of the furnace, clean the steel tapping port with a steel rod to ensure that the steel tapping port is unobstructed, adjust the tilting angle of the furnace, hold the handle 5 on the plug body 1 and push it into the steel tapping port, insert the plug body 1 into the steel tapping port, and then adjust the support plate 2 2 and the outer wall of the converter, adjust the position of the slider 3 so that the distance between the support plate 22 and the outer wall of the converter is within the stroke of the screw 23. After locking the position with the locking screw 9, rotate the rotating rod 21 to make the screw 23 move forward on the support plate 22, and move toward the outer wall of the converter with the suction cup 24. The suction cup 24 adsorbs the outer wall of the converter under the advancement of the screw 23, thereby fixing the plug body 1 and effectively preventing the plug body 1 from falling off during use. The plug body 1 blocks the overflow of flue gas and high-temperature slag in the furnace, thereby preventing smoke and dust from polluting the environment and effectively preventing the high-temperature reactants in the furnace from being ejected, thus preventing the occurrence of injuries.

[0020] Specifically, symmetrically arranged T-slots 10 are provided on both sides of the plug body 1, and the slider 3 is slidably installed on the T-slot 10, so that the slider 3 can adjust its position under the guidance of the T-slot 10 to meet the use requirements of different steel outlets.

[0021] Preferably, the locking member is two locking screws 9 , which are threadedly connected to the slider 3 , and the locking screws 9 are used to lock and fix the slider 3 to prevent the slider 3 from moving during use.

[0022] Furthermore, the locking assembly 2 includes a support plate 22, a screw 23, a suction cup 24 and a rotating rod 21. One end of the support plate 22 is connected to the slider 3, the screw 23 is threadedly connected to the support plate 22, the lower end of the screw 23 is rotatably connected to the suction cup 24, and the upper end of the screw 23 is connected to the rotating rod 21. The rotating rod 21 is rotated to allow the screw 23 to move forward on the support plate 22 and move toward the outer wall of the converter with the suction cup 24. The suction cup 24 adsorbs the outer wall of the converter under the push of the screw 23, thereby fixing the plug body 1 and effectively preventing the plug body 1 from falling off during use.

[0023] Furthermore, the plug body 1 includes a sealing block 12, a bottom block 13 and a top block 11. The two ends of the sealing block 12 are respectively connected to the bottom block 13 and the top block 11. The outer edge of the sealing block 12 is provided with sealant 7. The sealing block 12, the bottom block 13 and the top block 11 are an integrated structure. The sealant 7 on the sealing block 12 increases the friction coefficient, which can make the plug more stable at the steel outlet.

[0024] Furthermore, a fireproof pad 6 is provided at the bottom of the plug body 1. The fireproof pad 6 is made of quartz sand. Quartz sand has the characteristic of high temperature resistance. The fireproof pad 6 effectively prevents the plug body 1 from being damaged when the high-temperature reactants in the furnace are sprayed out, thereby playing a protective role.

[0025] When the slag stopper at the steel outlet of the converter of this embodiment is in use, the slag stopper at the steel outlet of the converter of this embodiment is adjusted to the tilting angle of the furnace, the steel outlet is cleaned with a steel rod to ensure that the steel outlet is unobstructed, the tilting angle of the furnace is adjusted, the handle 5 on the plug body 1 is held to push the steel outlet, and the plug body 1 is inserted into the steel outlet. Then, according to the distance between the support plate 22 and the outer wall of the converter, the position of the slider 3 is adjusted so that the distance between the support plate 22 and the outer wall of the converter is within the stroke of the screw 23. After locking the position by the locking screw 9, the rotating rod 21 is rotated to make the screw 23 move and advance on the support plate 22, carrying the suction cup 24 toward the outer wall of the converter. The suction cup 24 adsorbs the outer wall of the converter under the push of the screw 23, thereby fixing the plug body 1 and effectively preventing the plug body 1 from falling off during use. The plug body 1 plays a role in blocking the flue gas and high-temperature steel slag in the furnace from overflowing, thereby preventing smoke and dust from polluting the environment and effectively preventing the high-temperature reactants in the furnace from being ejected, thus eliminating the occurrence of injury accidents. The utility model provides a converter tapping port slag blocking plug, which effectively prevents environmental pollution and eliminates the occurrence of injuries, and has the characteristics of high safety and strong practicality.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
