Изобретение относитс к черной металлургии , в частности к контролю кислородно-конвертерного процесса.This invention relates to ferrous metallurgy, in particular to the control of an oxygen converter process.
Известен способ контрол шлакового режима в конвертере по ходу продувки н}тем измерени электросопротивлени газа между фурмой и ванной. Однако известный способ характеризуетс невысокой точностью и сложностью реализации, нанример необходимостью изолировани фурмы или стержн от земли, применением внешнего источника питани , подключением к подвижной фурме электрических цепей.There is a known method of controlling the slag mode in the converter during the blowing process to measure the electrical resistance of the gas between the lance and the bath. However, the known method is characterized by low accuracy and complexity of implementation, for example, the need to isolate a tuyere or rod from the ground, use an external power source, connect electrical circuits to a moving tuyere.
Дл увеличени точности контрол процессов шлакообразовани и облегчени контрол предлагаетс периоды вспенивани и сворачивани шлака определ ть по переменной составл ющей э.д.с. в цепи фурма-ванна-земл -фурма . При этом генератором э.д.с. вл етс реакционна зона, в которой имеютс направленные потоки ионов газа и жидкости, а также образуетс термо-э.д.с. Переменна составл юща этой э.д.с. можетIn order to increase the control accuracy of the slag formation process and to facilitate the control, the periods of slag expansion and coagulation are proposed to be determined from the variable component emf. in the chain lance-bath-earth-lance. In this case, the generator emf. is a reaction zone in which there are directional flows of gas and liquid ions, as well as thermo-emf. The variable component of this emf. can
быть измерена путем наведени э.д.с. во вторичной обмотке трансформатора, дл которого первичной обмоткой вл етс цепь фурма-ванна-земл -фурма .be measured by pointing emf in the secondary winding of a transformer, for which the primary winding is a lance-bath-earth-lance circuit.
Использование предлол енного способа позвол ет контролировать процессы шлакообразовани , в частности период и велнчпну вспенивани шлака и увеличение жндконодвижности шлака в последний период продувки, что открывает возможность управлени пенообразованием по ходу конвертерной плавки .The use of the pre-molded method makes it possible to control the processes of slag formation, in particular, the period of well slag foaming and the increase in slag mobility in the last purge period, which opens up the possibility of controlling the foaming during converter melting.
Предмет изобретени Subject invention
Способ контрол шлакового режима конвертерной плавки, включающий измерение э.д.с. в электрической цепи фурма-ванпа- земл -фурма, отличаю/цийс тем, что с целью увеличени точности и облегчени контрол , периоды вспенивани и сворачиванн шлака определ ют по перед1еиной составл ющей э.д.с. в этой цепи.The method of control of the slag mode converter smelting, including the measurement of emf. in the electrical circuit of the lance-vanpasel-lance, distinguished by the fact that in order to increase accuracy and ease of control, the foaming and rolled slag periods are determined by the front component emf. in this chain.
