Abstract
The present invention discloses a ladle wall laying method which belongs to a laying method for casting linings of fusant containers. When working layer parts under slag line bricks in permanent layers of linings of ladle walls are thoroughly repaired, ladle wall layer bricks and inner layer bricks are laid; in medium repair, fallen inner layer bricks are pasted and repaired, and thereafter, the fallen inner layer bricks can be continuously pasted and repaired for many times in minor repair. Because the paste and repair are carried out on the basically-flat surfaces of ladle wall layer bricks after the inner layer bricks fall, the labor intensity of repair is reduced; the inner layer bricks are laid or pasted and repaired by close contact with the ladle wall layer bricks, ladles can not be in overweight caused by liquid steel penetration, and the present invention extends the service life of the ladles and reduces the consumption of refractory materials.
Description
The present invention relates to a kind of ladle wall laying method, belong to the building method of casting fused mass container lining, be specially adapted to use the ladle of high-alumina brick as bag wall working lining.
In the prior art, the ladle wall lining is the working lining part below the slag line brick in its permanent layer, many thick operational layer bricks of 170～210mm of when repairing entirely, building by laying bricks or stones, use certain number of times, as all after dates of two light maintenances, carry out subsidizing mid-term, subsidize the thick brick of one deck 30～56mm on the surface of operational layer brick again and continue to use.This building method because the operational layer brick of building by laying bricks or stones when repairing is thicker entirely, causes its thermograde in the wall thickness direction bigger, be easy to generate and peel off, when operational layer brick comes off during for high-alumina brick particularly seriously, influence service life, cause the operational layer brick surface irregularity simultaneously.Mid-term is when subsidizing, because the operational layer brick surface is rough and uneven in surface, also is bonded with cold steel or slag, the cleaning work amount is big, subsidize difficulty, although joint sealing material has been filled in the gap of subsidizing between layer brick and the former operational layer brick, because the gap is inhomogeneous, molten steel very easily infiltrates and forms cold steel, cause ladle overweight, be forced to overhaul in advance, make the consumption of refractory material increase, cost rises.
The purpose of this invention is to provide a kind of ladle that alleviates and repair labour intensity, improve ladle service life, reduce the ladle wall laying method of refractory consumption,, increase economic efficiency to reduce production costs.
The objective of the invention is to realize by following measure.
A kind of ladle wall laying method, the following working lining part of slag line brick in the permanent layer of bag in the wall liner, when repairing entirely, build by laying bricks or stones wrap the parietal layer brick and the internal layer brick two-layer; Subsidize the internal layer brick that come off when repairing mid-term; Can continue repeatedly when light maintenance, the internal layer brick that comes off to be subsidized thereafter.
The too thin security that can influence operation of bag parietal layer brick, and the too thick ladle deadweight increase volume that can cause reduces; The internal layer brick is prerequisite can use certain number of times, reduces thickness simultaneously as far as possible, so that the ladle weight reduction increases volume.The thickness of general bag nogging is 100～170mm, and internal layer brick thickness is 30～65mm.
The advantage that compared with prior art the present invention had is: owing to subsidize is to carry out on the internal layer brick comes off the bag parietal layer brick surface of back substantially flat, and the cold steel of bonding does not need cleaning, is easy to subsidize, and has alleviated the labour intensity of repairing.The internal layer brick is close to that the bag parietal layer is brick to be built or subsidize, and can invar water infiltrates to form cold steel, and causes ladle overweight, has improved the service life of ladle, has reduced refractory consumption.Through nearly 2 years of on-the-spot ladle trial production proof continuously: ladle average packet order of adopting the inventive method to build its bag wall liner by laying bricks or stones can reach 120 times/bag labour, make every bag labour compare for 90 times with the ladle average packet that adopts art methods to build bag wall liner by laying bricks or stones, life-span improves 33.3%, and some ladle even the bag order that surpasses whole bag reach 301 times/bag labour.Refractory consumption is reduced to steel 2.9kg per ton, compared with prior art the ton of anti-material steel unit consumption decline 0.2-0.3 kilogram.Ton steel cost on average can reduce by 1.2 yuans, and economic benefit is very remarkable.
Below in conjunction with accompanying drawing embodiments of the invention are described in detail.
The ladle lining of accompanying drawing 1 for adopting ladle wall laying method of the present invention to build by laying bricks or stones.
Ladle wall laying method of the present invention is: slag line brick 2 following working lining parts in the permanent layer 1 of bag in the wall liner, when repairing entirely, build by laying bricks or stones wrap parietal layer brick 3 and internal layer brick 4 two-layer, as shown in the figure; Subsidize the internal layer brick 4 that come off when repairing mid-term, can continue thereafter repeatedly when light maintenance the internal layer brick 4 that comes off to be subsidized.The thickness of bag parietal layer brick 3 is 170mm, and the thickness of internal layer brick 4 is 50mm.
The ladle of Quan Xiuhou uses certain number of times, and during as 50～70 times, internal layer brick 4 comes off, and carries out this moment repairing mid-term, subsidizes internal layer brick 4 backs and continues to use.Thisly can continue repeatedly to carry out when the light maintenance to subsidizing of carrying out of the internal layer brick 4 that comes off.
