Problems solved by technology
However, due to the frequent operation of the converter, the labor intensity of the converter operator is relatively high, and the experience requirements are relatively high.
However, relying on the operator to control the converter, negligence will inevitably occur, which may cause the melt to flow back into the wind hole and block the wind hole, resulting in equipment damage
More seriously, it may also lead to safety accidents
In addition, if the operator is relied on to judge whether there is an accident in the converter, it is easy to misjudgment, especially when the auxiliary equipment related to the converter fails, because the converter body cannot be turned to a safe angle in time, the melt will flow backward into the wind eye and even block it. wind eye

Embodiment Construction
[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.
[0020] Such as figure 1 Shown is a flow chart of a method for controlling a converter accident dumping back to the furnace according to an embodiment of the present invention. It should be noted that in the embodiment of the present invention, three angles are set for the reheating of the converter, such as the first angle to the third angle. Of course, those skilled in the art can also choose to increase the number of angles set, thereby improving the control accuracy. Those skilled in the art can also...

The invention provides a tilting control method of converter accidents. The method comprises the following steps: detecting the current angle of a converter; judging whether the converter and related auxiliary equipment have faults or not; if the judging result shows that the converter or the related auxiliary equipment has faults, controlling the converter to rotate forward from a first angle, and closing an oxygen-controlled rapid cut-off valve; judging whether the converter rotates to a second angle from the first angle; if the judging result shows that the converter rotates to the second angle from the first angle, opening an emptying valve, and closing a blow valve; and controlling the converter to rotate to a third angle from the second angle and then stop, so as to expose the air hole of the converter above the liquid level of melt. In the invention, by judging whether the converter and the related auxiliary equipment of the converter have faults or not, the converter is automatically controlled to rotate to a safe angle after the faults of the related auxiliary equipment are found, so as to expose the air hole of the converter above the liquid level, thus preventing the air hole of the converter from being blocked off, and improving the operating safety of the converter.
Description
Technical field [0001] The invention relates to the technical field of metallurgical manufacturing and design, in particular to a converter accident tilt control method. Background technique [0002] Converter smelting is one of the most commonly used smelting methods for non-ferrous metal smelting. The furnace body of the converter is cylindrical, and the inner lining is made of refractory materials. It is heated by chemical reaction heat during blowing and does not require an external heating source. It is currently an important steelmaking equipment and can also be used for the smelting of non-ferrous metals such as copper and nickel. However, because the converter needs frequent operation, the labor intensity and experience requirements of the converter operator are relatively high. However, depending on the operator to control the converter, negligence will inevitably occur, which may cause the melt to flow back into the wind eye and block the wind eye, resulting in equipme...
