Embodiment Construction
[0019] The patent will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] A kind of VOD furnace water cooling leakage automatic alarm control system, such as figure 1 As shown, it includes VOD furnace water cooling system, alarm input system, and alarm control system; VOD furnace water cooling system includes: tank lid car 1, steel ladle 11, water-cooled oxygen lance 12, water-cooled shield cover 13, return water pipe 18, water inlet pipe 19, vacuum The main function of pipeline 10 is to utilize circulating water to cool the oxygen lance and the shielding cover to prevent from being burned by molten steel. The alarm input system includes water inlet flow meter 3, return water flow meter 14, temperature sensor 8, PLC input and output module 5, Ethernet module 17, WinCC monitoring system 15; mainly receives cooling water flow signal and exhaust gas temperature signal, and sends these The signal is transmitted to...

The invention belongs to the technical field of smelting auxiliary equipment, and mainly relates to a VOD furnace water-cooling water leakage automatic alarm control system and a control method. The invention provides the VOD furnace water-cooling water leakage automatic alarm control system and the control method, which are used for solving the problems that in the prior art, no automatic water leakage alarm and control system exists, so that once if a water leakage phenomenon happens, timely and accurate treatment cannot be carried out, and the safety accident can be caused. A VOD furnace water-cooling system is improved, so that a VOD furnace can analyze and judge a water inflowing flow value, a water returning flow value and a waste gas temperature value of a water-cooling system in real time during smelting; if a difference value of the water inflowing flow value and the water returning flow value of the water-cooling system exceeds a specified value, water leakage of the water-cooling system can be determined, and a buzzer immediately alarm to remind operating personnel to check and treat in time; if the alarm is not treated after continuing for a long time, the system can automatically break a vacuum state of the VOD furnace, so that the occurrence of the phenomenon of quality accident or safety accident caused by severe water leakage is prevented.
Description
technical field [0001] The invention belongs to the technical field of smelting auxiliary equipment, and mainly relates to an automatic alarm control system and control method for water cooling leakage of a VOD furnace. Background technique [0002] VOD furnace is currently an important equipment for smelting high-quality steel. By vacuuming, the molten steel is decarburized by oxygen blowing in a vacuum state, and high-chromium stainless steel is produced by blowing argon and stirring. The equipment has many advantages such as simple operation and high quality, so it has become a necessary refining method for steel foundries. [0003] However, since the molten steel is smelted in a closed space, the operator cannot visually see the smelting state of the ladle and molten steel. If water leakage occurs in the water cooling system such as the shielding cover and the oxygen lance, the water will directly enter the molten steel, resulting in failure to smelt or even a safety ac...
