Description

Technical Field

[0001] The utility model relates to the technical field of converters, in particular to a converter tapping angle control device. Background Art

[0002] The process of vanadium extraction in the converter is to discharge vanadium slag after the semi-steel is discharged. The density of vanadium slag is lower than that of semi-steel, and it floats on the surface of semi-steel. During the semi-steel discharge process, semi-steel flows out from the steel outlet. When the furnace shaker sees the vanadium slag flowing out, he immediately lifts the furnace to stop the discharge of semi-steel. During the process of separating semi-steel and vanadium slag in the converter vanadium extraction, the flow rate and flow of the molten steel are controlled to help regulate the separation of semi-steel and vanadium slag in the converter vanadium extraction process.

[0003] The existing referenceable Chinese utility model patent with announcement number CN2524849Y discloses a steel-discharging machine, which includes a steel-discharging rod, a lifting mechanism and an advance-retreat movement mechanism, characterized in that: a crank is provided on the transmission shaft of the lifting mechanism, a rotating shaft is provided below the front of the steel-discharging rod, a swing rod is provided at each end of the rotating shaft, the two ends of the pull rod are respectively hinged with the crank and the swing rod, a supporting wheel is provided at the end of each of the two swing rods and supported on the lower surface of the steel-discharging rod, an advance-retreat transmission mechanism is provided on the lower machine base of the rear of the steel-discharging rod, the advance-retreat mechanism includes a motor and a reducer, a gear is provided at each end of the transmission shaft and meshes with a rack on the lower surface of the steel-discharging rod, and a pressure wheel is provided on the upper part of the box of the advance-retreat transmission mechanism and placed on the upper surface of the steel-discharging rod. Due to the use of a transmission mechanism with a gear and a rack and a four-link lifting mechanism, the steel-discharging machine has the advantages of smooth advance and retreat movement, small starting torque of the lifting mechanism and good locking performance.

[0004] The existing converter steel tapping structure angle adjustment equipment rotates the converter to make the molten steel flow out from the opening of the converter. After the converter reaches the set angle, the inertia of the converter will cause the molten steel in the furnace to oscillate, causing the molten steel inside the converter and other substances in the converter to shake, resulting in the mixing of molten steel and impurities, affecting the quality of the molten steel. At the same time, the existing converter cannot accurately control the rotation angle of the converter according to actual conditions, so it is impossible to control the flow rate and flow rate of the molten steel.

When the stepper motor is locked, the rotation of the transmission gear can be limited, thereby limiting the drive shaft to a specific rotation angle, so as to control the rotation angle of the converter, thereby controlling the speed and flow rate of molten steel flowing out of the converter.
