[0032] The condition of the original molten iron is: S 原 : 0.04%, the treatment temperature is 1480°C, and the height of molten iron in the ladle is 550mm.

[0033] The processing result requirement is: S 终≤0.015%, Mg 残 ≥0.04%

[0034] Feeding line parameter selection calculation:

[0035] ●The optimal feeding line speed selection for feeding the bottom of the bale: 23m / min;

[0036] ●Processing time selection: 40~60s / package;

[0037] ●The diameter of the magnesium core wire is determined by the amount of magnesium added per unit time and the effective rate of magnesium in molten iron under this condition: if the processing time is 50s / bag, the length of the feeding wire is 40m / t, that is, 20m / bag. Assuming that the effective rate of magnesium is 60%, the total amount of magnesium that needs to b...

Embodiment 2

[0046] Embodiment 2. The conditions for spheroidizing and inoculating 1000kg / pack of molten iron with magnesium cores or bundles of magnesium cored wires are as follows: S 原 : 0.02%, the treatment temperature is 1460°C, and the height of molten iron in the ladle is 600mm. The processing result requirement is: S 终 ≤0.012%, Mg 残 ≥0.04%

[0047] Feeding line parameter selection calculation:

[0048] ●The optimal feeding line speed selection for feeding the bottom of the bale: 25m / min;

[0049] ●Processing time selection: 50~70s / package;

[0050] ●The diameter of the magnesium core wire is determined by the amount of magnesium added per unit time and the effective rate of magnesium in molten iron under this condition: if the processing time is 70s / bag, the length of the feeding wire is 30m / t, that is, 30m / bag. Assuming that the effective rate of magnesium is 50%, the total amount of magnesium to be added is 950g / t, that is, 950g / bag. One ф4.8mm magnesium wire or three ф2.8mm...

[0060] Embodiment 3. The conditions for spheroidizing and inoculating the original molten iron for 1500kg / pack of molten iron with magnesium core or bunch of magnesium core cored wire are as follows: S 原 : 0.06%, the treatment temperature is 1450℃, and the height of molten iron in the ladle is 800mm. The processing result requirement is: S 终 ≤0.012%, Mg 残 ≥0.04%

[0061] Feeding line parameter selection calculation:

[0062] ●The optimal feeding line speed selection for feeding the bottom of the bale: 33m / min;

[0063] ●Processing time selection: 50~90s / package;

[0064] ●The diameter of the magnesium core wire is determined by the amount of magnesium added per unit time and the effective rate of magnesium in molten iron under this condition: if the processing time is 90s / bag, the length of the feeding wire is 33m / t, that is, 50m / bag. Assuming that the effective rate of magnesium is 60%, the total amount of magnesium that needs to be added is 1267g / t, that is, 1900g / bag. ...

Abstract

The invention relates to a magnesium-core core-spun yarn feeding method and device used in melted water disposal. The method is characterized in that initial shape of lateral section is basically consistent with the shape when core-spun yarn enters into melted water in the whole process of feeding core-spun yarn into melted water to handle bottom of sack. Device to realize the process mainly is core-spun yarn feeding machine, which comprises feeding machine box and at least one wire feeding channel in box. Wire feeding channel comprises leading-in entrance on one side of box, core-spun yarn delivery line on the opposite side to leading-in entrance and core-spun yarn actuating device set in box. Leading-in entrance is cross-shape entrance that comprises two groups of vertically-arranged non-driving rollers with two layers. Actuating device comprises one group or more Y-shape driving wheel groups distributed with 120 Deg. and arranged on the same wire feeding channel. A group of driving wheels have at least one action wheel. Three action wheels in one driving wheel group form a circular orifice. Advantages: realizing feeding of magnesium core or magnesium-core core-spun yarn that demands heat insulation of powder layer.

Description

technical field [0001] The invention relates to a wire feeding machine for magnesium core cored wire used for molten iron treatment. Background technique [0002] At present, the known cored wire is composed of a steel strip and powder wrapped in the steel strip. Therefore, the function of the wire feeding machine is to feed the cored wire into the molten iron at a certain speed to treat the bottom of the ladle and the molten iron or molten steel. To react, the wire feeding machine generally includes a wire feeding machine box body, and at least one wire feeding channel is provided on the box body. The cored wire outlet conduit with the opposite mouth, and the cored wire driving mechanism located in the wire feeding machine box, the cored wire driving mechanism uses one or more sets of double feeding wheels clamped oppositely to drive the cored wire, Realize the wire feeding process. The cross-sectional shape of the cored wire fed out after being cl...
