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 forms by wrapping the end, Bao Bi and bag mouth, and the inner side of the bag end, bag wall is provided with the working lining by laying fireproof bricks, at the bottom of described bag, forms involucrum with bag wall, and working lining is usually said liner namely.In ladle shipment molten iron process, liner is subject 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 degree, has further increased the weight of the erosion to liner.Moreover, in Hot Metal Pretreatment, adding desulfurization inorganic agent, basicity changes greatly, ladle liner is corroded serious, adds and stirs washing away and temperature fluctuation that batch operation causes of molten iron, and the damage that particularly bottom and slag line are paid no attention to of ladle inner side aggravates.This,, by increasing the heat loss of molten iron in ladle, reduces energy consumption.More seriously,, because the mobility of molten iron is very strong, in this case, just easily there is serious seepage, leak iron accident in ladle.
Summary of the invention
The technical issues that need to address of the present invention are to 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:
The ladle with anti-seepage heat preservation layer, comprise the end, Bao Bi, Bao Zui, at the bottom of described bag, bag wall inner side be provided with the working lining by laying fireproof bricks, at the bottom of described bag and between the working lining at the bag end, be provided with bag end anti-seepage heat preservation layer, between the working lining of Bao Biyu bag wall, be provided with bag wall anti-seepage heat preservation layer;
At the bottom of described bag, anti-seepage heat preservation layer comprises and is laid on the bag fibre glass chopped stand mat at the end, fibre glass chopped stand mat with wrap fire-resistant stamp mass that between the working lining at the end, casting quality percentage is 1:0.15～1:0.20 and the mixture of water;
Described bag wall anti-seepage heat preservation layer comprises the asbestos board that sticks on bag wall inner side, the side that the working lining of bag wall wraps wall has relatively sticked glass wool cloth, the castable refractory that between described asbestos board and glass wool cloth, casting quality percentage is 1:0.30～1:0.35 and the mixture of water;
The building method with the ladle of anti-seepage heat preservation layer, said method comprising the steps of,
A. with and material machine by castable refractory with water by mass percentage for the ratio of 1:0.30～1:0.35 mixes standby;
B., distance inner in ladle wrapped wall 80～100mm place, working lining with arc iron bag laying fireproof bricks bag wall, when bag wall working lining build by laying bricks or stones ladle height 1/2～2/3 time, between the gap of the working lining of Bao Biyu bag wall, stick one deck asbestos board near Bao Biyi side, working lining at 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 glass wool cloth bottom covers the bottom surface in gap between the working lining of Bao Biyu bag wall; The mixture of the castable refractory making in step a and water is poured into the gap between asbestos board and glass wool cloth in batches, the limit that allows mixture that glass wool cloth is covered to bottom surface is pushed down, with vibrating head, the space between mixture is emptying, until mixture is filled up to the height of the working lining of built by laying bricks or stones bag wall;
C. carry out the building by laying bricks or stones of working lining of the bag wall of residual altitude, after having built by laying bricks or stones, gap between asbestos board and glass wool cloth continue minute make in annotations and comments step a castable refractory and the mixture of water, with vibrating head, the space between mixture is emptying, until mixture is filled up to the height of ladle, complete the cast of bag wall anti-seepage heat preservation layer;
D. wait wrap wall anti-seepage heat preservation layer and bag wall working lining bonding firmly after, at Bao Dipu layer of glass blanket, fire-resistant stamp mass is mixed in the ratio of 1:0.15～1:0.20 with water, water to the bag end and shakeout, hand-held plate vibration machine, by fire-resistant stamp mass vibration pulp, is built the bag working lining at the end by laying bricks or stones behind floating surface.
Owing to having adopted technique scheme, the technological progress that the present invention obtains is:
The present invention, between the involucrum and liner of ladle, 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 in batches.Use ladle of the present invention, will greatly reduce the possibility that causes bottom pour ladle accident due to cylinder-packing defect, compare with common ladle, heat loss decreased average 40～50%, and anti-seepage heat preservation layer is reusable, 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 is used is common, and knotting method is simple, and this anti-seepage heat preservation layer good integrity, sturdy and durable, anti-seepage heat preservation layer is reusable, because integral body knotting anti-seepage heat preservation layer is seamless, can stop bottom pour ladle accident and occur, greatly improve production security.
