Abstract
The present invention relates to a seam jointing material for the building of magnesium-carbon bricks and aluminum-magnesium-carbon bricks. The present invention has the technical scheme that the seam jointing material contains solid powder material and liquid binding agent, wherein the solid powder material is prepared by mixing the components of the following weight percentage content: 70 to 85% of magnesite powder, 5 to 15% of flake graphite, 3 to 10% of solid resin, 1 to 5% of silicon carbide, 1 to 5% of high temperature pitch and 0.5 to 3% of metallic silicon. The liquid binding agent is prepared by mixing 30 to 60% of high furan resin, 15 to 35% of alcohol and 15 to 35% of wash oil. When the seam jointing material is used, the solid powder material and the liquid binding agent are stirred into a uniform pasty substance according to the weight ratio of 1:0.2 to 0.3. The present invention uses the high furan resin as the binding agent, the erosion resistance of the seam jointing material is enhanced, and the early damage to magnesium-carbon bricks and aluminum-magnesium-carbon bricks is avoided. The seam jointing material for the building of magnesium-carbon bricks and aluminum-magnesium-carbon bricks has the advantages of strong slag erosion resistance capability, low maintenance frequency, high combination strength, normal temperature solidification possibility, good construction performance, simple preparation technology and convenient use.
Description
One, technical field
The invention belongs to the unshape refractory technical field.Relate in particular to a kind of magnesia carbon brick and Al2O3MgOC Bricks joint filler of building by laying bricks or stones.
Two, background technology
The development of magnesia carbon brick has had the history in more than 30 year, because of its good slag resistance and anti-thermal shock stability, has been widely used in converter, electric furnace and positions such as ladle furnace liner and ladle slag line.Al2O3MgOC Bricks because of the introducing of carbonaceous material, is widely used at the ladle liner working lining equally.Find that by investigation ladle slag line magnesia carbon brick and Al2O3MgOC Bricks at first begin damage from brickwork joint in the process of using, and part or corner angle fracture take place for about ten times in use.Because ladle brick is subjected to acutely washing away of molten steel and slag, rupture or peel off the position by the scour out round slip surface, make magnesia carbon brick and Al2O3MgOC Bricks working face be the steamed bun shape and corrode.Along with the growth of duration of service, molten slag is constantly invaded from brickwork joint and crackle, can cause that brickwork joint oozes steel when serious, causes the leading damage of slag line magnesia carbon brick simultaneously, and bag is descended age.
At present, in the STEELMAKING PRODUCTION process, building ladle brick by laying bricks or stones mainly is magnalium matter, magnalium matter, magnesia and magnesium carbonaceous mud with material, and combination is water system combination or phosphoric acid salt combination.Its defective is the slag corrosion resistance ability, and bonding strength is low, and frequency of maintenance height in the use influences work-ing life of ladle.
Three, summary of the invention
The purpose of this invention is to provide that a kind of slag corrosion resistance ability is strong, bonding strength is high, frequency of maintenance is low, can meet or exceed the novel joint filler that magnesia carbon brick and Al2O3MgOC Bricks are used of building by laying bricks or stones of magnesia carbon brick and Al2O3MgOC Bricks performance.This joint filler can solve the leading damage problem of brickwork joint, thus the work-ing life that can improve ladle.
For finishing above-mentioned task, the technical solution used in the present invention is: this joint filler comprises solid powder and two components of liquid wedding agent: percentage composition meter by weight, solid powder is mixed by 70～85% magnesia powder, 5～15% crystalline flake graphite, 3～10% solid resin, 1～5% silicon carbide, 1～5% hard pitch, 0.5～3% Pure Silicon Metal, and the liquid wedding agent is mixed by 30～60% high furane resin, 15～35% ethanol, 15～35% washing oil; During use be that 1: 0.2～0.3 ratio stirs into uniform paste substance by weight with solid powder and liquid wedding agent.
The granularity of described solid powder is respectively: magnesia powder≤0.088mm, crystalline flake graphite≤100 orders, solid resin≤200 orders, silicon carbide≤200 orders, hard pitch≤200 orders, Pure Silicon Metal≤180 orders.
It is wedding agent that the present invention adopts high furane resin, because the carbon residue rate height of high furane resin, thereby made full use of the good slag corrosion resistance ability of carbonaceous material, further improved the corrosion-resistant property of joint filler, thereby can reduce the erosion rate of brickwork joint greatly, also make the erosion rate of magnesia carbon brick and Al2O3MgOC Bricks reduce, avoided the leading damage of magnesia carbon brick and Al2O3MgOC Bricks, the access times of magnesia carbon brick and Al2O3MgOC Bricks have been improved, reduce workman's maintenance task, improved the turnover rate of ladle, increased economic efficiency greatly.
Not only the slag corrosion resistance ability is strong, frequency of maintenance is low in the present invention, bonding strength is high; The advantage of also have the energy ambient cure, have good workability, blending process is simple, easy to use.Can also toast use with magnesia carbon brick and Al2O3MgOC Bricks in addition, the ladle that lays can use on-site hoisting to move.
Four, embodiment
A kind of magnesia carbon brick and Al2O3MgOC Bricks joint filler of building by laying bricks or stones.The technical scheme that present embodiment adopts is: this joint filler comprises solid powder and two components of liquid wedding agent.Solid powder is to be main raw material with magnesia powder and crystalline flake graphite, adds solid resin, silicon carbide, hard pitch and Pure Silicon Metal and mixes.Percentage composition meter by weight, magnesia powder is 75～85%, and crystalline flake graphite is 5～10%, and solid resin is 5～10%, and silicon carbide is 1～4%, and hard pitch is 2～5%, and Pure Silicon Metal is 0.5～2%; The liquid wedding agent is to be main raw material with high furane resin, and the ethanol and the washing oil that add some amount mix, and wherein high furane resin are 40～60%, and ethanol is 15～30%, and washing oil is 15～30%.
Wherein, the granularity of solid powder is respectively: magnesia powder≤0.088mm, crystalline flake graphite≤100 orders, solid resin≤200 orders, silicon carbide≤200 orders, hard pitch≤200 orders, Pure Silicon Metal≤180 orders.
