(54) СПОСОБ ОБЖИГА ФУТЕРОВКИ СТАЛЕПЛАВИЛЬНОГО(54) METHOD FOR BURNING STEEL LAYING
КОНВЕРТЕРАCONVERTER
лежащих бункеров и дальнейший подъем температуры осуществл ют со скоростью 10- 15°С/мин. В дальнейшем кокс загружают каждые 10 мин по 400 кг. При достижении температуры 1000-1100°С делают выдержку в течение 30-40 мин.lying bins and further temperature rise carried out at a speed of 10-15 ° C / min. In the future, coke is loaded every 10 minutes at 400 kg. When the temperature reaches 1000-1100 ° С, the shutter speed is made for 30-40 min.
Восстаповительпую среду и равномерное температурное поле по высоте конвертора создают , например, тем, что обжиг ведут при выключенном дымососе. При этом скорость движени дымовых газов, выход ших из конвертера, весьма мала и количество выносимого ими тепла минимально, что обеспечивает равномерный нагрев футеровки по высоте конвертора. Мала скорость выхода дымовых газов приводит к тому, что парциальное давление кислорода внутри конвертера существенно ниже, чем при известном сиособе, что обеспечивает восстановительную среду при обжиге.The recovery medium and the uniform temperature field along the height of the converter are created, for example, by the fact that the firing is carried out with the smoke exhauster off. At the same time, the speed of movement of the flue gases leaving the converter is very small and the amount of heat carried by them is minimal, which ensures uniform heating of the lining along the height of the converter. The low flue gas exit rate leads to the fact that the partial pressure of oxygen inside the converter is significantly lower than with the known siooba, which provides a reducing environment during firing.
Во врем обжига скорость подъема температуры регулируют подачей кислорода, мен ее в указанном дл каждой стадии интервале. Температуру измер ют при помощи термопары , заложенной заподлицо с рабочей поверхностью фзтеровки в месте перехода от цилиндрической части к горловине (на уровне сталевыпускного отверсти ).During firing, the rate of temperature rise is controlled by the supply of oxygen, which changes in the interval indicated for each stage. The temperature is measured using a thermocouple laid flush with the working surface of the fzterovka at the transition point from the cylindrical part to the throat (at the level of the steel outlet).
Стойкость футеровки 300-350-тонного конвертера , обожженной указаным способом, увеличиваетс иримерно на 100 плавок.The durability of a 300–350-ton converter lining annealed by this method is increased and increased by 100 heats.
