Problems solved by technology
[0002] Converter tapping means that molten steel enters the ladle from the converter. When tapping, due to the frictional erosion and oxidation erosion of high-temperature molten steel and slag, the environment of the ladle car during the tapping of the converter is very harsh, and it needs to be continuously repaired and replaced, so that not only It will affect the production cycle, and affect the quality of molten steel and production stability
[0003] Due to the harsh environment of the ladle car when the converter is tapping steel, the electric cable reel is generally used in the power supply industry. However, due to the rotating slip ring involved and the fixed length of the cable, the cable is often burned out at the end of the ladle car due to high temperature and red slag. Generally, the whole cable needs to be replaced after the second scalding and cutting process. In addition, due to the high temperature of the working environment and high concentration of dust, there is no effective technical means to detect the position of the ladle car.

Embodiment 1
[0011] Arranged according to the specific process of the steelmaking plant, such as figure 1 As shown, a light pulley is arranged at the lower position of the ladle car when it leaves the terminal building (the size of the pulley is determined according to the cable specification), and the weight of the counterweight is determined according to the moving stroke of the ladle car. In this design, ① the axle ladle car and the counterweight provide power, and the device No power source is required. ②Due to the one-time correspondence between the position of the counterweight and the position of the ladle car, it is very simple and reliable to measure the position of the ladle car. ③Because no electrical slip ring is needed, more cables can be installed at one time. The entire cable is replaced, which greatly saves the cost.

The invention discloses a movable power supply device for a molten steel and molten iron high-temperature liquid vehicle of a steelmaking plant. Light pulleys are arranged on the position, driving outof an endpoint workshop to the next position, of a ladle bogie, and operation of the ladle bogie during converter tapping is controlled through the light pulleys and counter weights; and the size ofthe light pulleys is determined according to the cable specification of the ladle bogie. The movable power supply device is mounted on the high-temperature liquid vehicle such as a tapping vehicle ofthe steelmaking plant, after a near-end cable of a molten steel vehicle is damaged, the cable does not need to be overall replaced, and only the damaged end needs to be cut off.
Description
technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a mobile power supply device for steel and molten iron high-temperature liquid vehicles in steelworks. Background technique [0002] Converter tapping means that molten steel enters the ladle from the converter. When tapping, due to the frictional erosion and oxidation erosion of high-temperature molten steel and slag, the environment of the ladle car during the tapping of the converter is very harsh, and it needs to be continuously repaired and replaced, so that not only It will affect the production cycle, and affect the quality of molten steel and production stability.
