Description
Technical field
The present invention relates to a kind of ladle and building method thereof, specifically a kind of ladle and building method thereof with anti-seepage heat preservation layer.
Background technology
Ladle of the prior art is comprised of the bag end, Bao Bi and bag mouth, and the inboard of the bag end, bag wall is provided with the working lining by laying fireproof bricks, forms involucrum with the bag wall at the bottom of the described bag, and working lining is usually said liner namely.In the ladle shipment molten iron process, liner is subjected to the chemical erosion effect of high temperature, thermal shock, mechanical wear and slag iron.In recent years, molten iron temperature has significantly raising than before, reaches as high as 1500 and reads, and has further increased the weight of the erosion to liner.Moreover, in the Hot Metal Pretreatment, add the desulfurization inorganic agent, basicity changes greatly, it is serious that the ladle liner is corroded, add to stir washing away and temperature fluctuation that batch operation causes of molten iron, the ladle inboard particularly bottom and the slag line damage of paying no attention to aggravate.This will increase the heat loss of molten iron in ladle, reduce energy consumption.More seriously, because the flowability of molten iron is very strong, in this case, serious seepage just occurs, leaks the iron accident in ladle easily.
Summary of the invention
The technical issues that need to address of the present invention provide the ladle with anti-seepage heat preservation layer and the building method thereof that a kind of security performance is good, thermal loss is low.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
Ladle with anti-seepage heat preservation layer, comprise the end, Bao Bi, Bao Zui, at the bottom of the described bag, the inboard of bag wall is provided with working lining by laying fireproof bricks, be provided with bag end anti-seepage heat preservation layer at the bottom of the described bag and between the working lining at the bag end, be provided with bag wall anti-seepage heat preservation layer between the working lining of Bao Biyu bag wall.
Further improvement of the present invention is: the anti-seepage heat preservation layer comprises and is laid on the bag fibre glass chopped stand mat at the end at the bottom of the described bag, and casting quality percentage is the fire-resistant stamp mass of 1:0.15～1:0.20 and the mixture of water between fibre glass chopped stand mat and the working lining that wraps the end.
Further improvement of the present invention is: described bag wall anti-seepage heat preservation layer comprises the asbestos board that sticks on bag wall inboard, the working lining of bag wall wraps the glass wool cloth that a side of wall sticks relatively, and casting quality percentage is the castable refractory of 1:0.30～1:0.35 and the mixture of water between described asbestos board and the glass wool cloth.
Have the building method of the ladle of anti-seepage heat preservation layer, said method comprising the steps of,
A. usefulness and material machine mix for subsequent use for the ratio of 1:0.30～1:0.35 castable refractory and water by mass percentage;
B., distance inner in ladle wrapped wall 80～100mm place, working lining with arc iron bag laying fireproof bricks bag wall, when the bag wall working lining build by laying bricks or stones the ladle height 1/2～2/3 the time, between the slit of the working lining of Bao Biyu bag wall, stick one deck asbestos board near the Bao Biyi side, working lining at the bag wall is spread glass wool cloth facing to a side of bag wall, the height on glass wool cloth top is concordant with the height of ladle, and the glass wool cloth bottom covers the bottom surface in slit between the working lining of Bao Biyu bag wall; The mixture of the castable refractory that makes among the step a and water is poured into the slit between asbestos board and glass wool cloth in batches, with vibrating head that the space between the mixture is emptying, until mixture is filled up to the height of the working lining of the bag wall of building by laying bricks or stones;
C. carry out the building by laying bricks or stones of working lining of the bag wall of residual altitude, build by laying bricks or stones finish after, slit between asbestos board and glass wool cloth continue minute make among the annotations and comments step a castable refractory and the mixture of water, with vibrating head that the space between the mixture is emptying, until mixture is filled up to the height of ladle, finish the cast of bag wall anti-seepage heat preservation layer;
D. wait the working lining that wraps wall anti-seepage heat preservation layer and bag wall bonding firmly after, at Bao Dipu layer of glass blanket, fire-resistant stamp mass and the water ratio in 1:0.15～1:0.20 is mixed, water to wrapping the end and shakeouing, hand-held plate vibration machine is built fire-resistant stamp mass vibration pulp by laying bricks or stones the bag working lining at the end behind the floating surface.
Because the technological progress of having adopted technique scheme, the present invention to obtain is:
The present invention utilizes the mixture of castable refractory and water, fire-resistant stamp mass and water to vibrate the whole anti-seepage heat preservation layer of knotting between the involucrum and liner of ladle in batches.Use ladle of the present invention, with greatly reducing because the cylinder-packing defective causes the possibility of bottom pour ladle accident, compare with common ladle, heat loss decreased average 40-50%, and the anti-seepage heat preservation layer is reusable, and number of times can reach more than 15 times, can not cause a large amount of cylinder-packing expenses to increase.The material that anti-seepage heat preservation layer of the present invention uses is common, and knotting method is simple, and this anti-seepage heat preservation layer good integrity, sturdy and durable, the anti-seepage heat preservation layer is reusable, because whole knotting anti-seepage heat preservation layer is seamless, can stop the bottom pour ladle accident and occur, greatly improve production security.
