转炉吹炼过程中钢水含炭量的变化,过去都只是凭肉眼观察炉焰来断定。这个方法只能在炭吹炼得很低、到接近终点火焰有明显变化时才能看出,不仅只能适用于冶炼低炭钢,而且易于过吹,影响钢的质量。利用仪表来测定吹炼过程中含炭量变化情况,使之能够在炭吹炼至要求含炭量时即停吹出钢,是扩大钢种的重要条件和改善钢质量的重要措施。近年来在法国、比利时等国曾研究和发展了例如火焰透明计、火焰温度计等多种光电控制仪表。但是
Changes in the carbon content of molten steel in the converter blowing process, in the past only by observing the furnace flame with the naked eye to determine. This method can only be very low in the carbon blowing, to the end of the flame when significant changes can be seen, not only applicable to smelting low carbon steel, but also easy to blow, affecting the quality of steel. The use of instrumentation to measure changes in the carbon content of the blowing process, making it possible to blow the carbon blowing out of carbon blowing out of steel, is an important condition to expand the steel and improve the quality of steel is an important measure. In recent years in France, Belgium and other countries have studied and developed such as flame transparency meter, flame thermometer and other photoelectric control instruments. but
