Abstract
This invention relates to an alkalescence light Mg olivine brick and its manufacturing method, in which, the brick is manufactured with olivine sand, Mg sand, coke, charcoal, pulp effluent in weight proportion, and the manufacturing method includes: adding particles of olivine sand, Mg sand, coke and charcoal into a sand mixing machine to be dry-mixed, then adding pulp effuluent to mix them in humid then adding olivine sand and Mg sand fine powder for mixed refining, then putting a mixed material into a die to be pressed on a rubbing machine to process it to a blank to be dried over 24h under 25-35deg.C natural temperature then to be dried in a drying kiln and sending the blank into a tunnel stove to get a product then cutting and grinding it to mold.
Description
Technical field:
It is heat insulation with being incubated the brick field, particularly a kind of weakly alkaline lightweight forsterite brick and method field of manufacturing thereof used to the present invention relates to all high temperature kilns such as building materials, metallurgy, machinofacture, petrochemical industry, electric power.
Background technology:
Along with development in science and technology, development of technology reaches the restriction to the kiln Installed capital cost, the building kiln is tending towards reducing with heavy brick consumption, and high-quality light-weight refractory goods are good with its high-temperature behavior, and normal temperature strength is big, thermal conductivity is low, heat-proof quality is good, can make kiln wall attenuate in construction, weight saving, reduce the advantage of executive cost, just progressively paid attention to by common people.
Clay matter, high alumina matter, acid light cinder brick such as siliceous at home, exploitation early, of a great variety, manufacturer is numerous.But in use, to be generally basic brick in the majority because of working lining in the high temperature kiln, the heat-insulation light brick of acid energy is used as it and is equipped with lining, exist the drawback that acid-base reaction at high temperature can take place, thereby cause its Applicable temperature scope lower, only using below 1200 ℃ generally speaking, therefore exploitation, development, the production of alkaline light cinder brick more and more become a kind of extension needs.
Summary of the invention:
In order to address the above problem, the present invention proposes a kind of weakly alkaline lightweight forsterite brick, can avoid because working lining basic brick that high temperature caused and the acid-base reaction that serves as a contrast light heat-insulation brick fully, be beneficial to improve the work-ing life of alkaline working lining brick reserve lining light heat-insulation brick, thereby alleviate its damage degree and speed.The technical solution used in the present invention is: a kind of lightweight forsterite brick is characterized in that it is made by weight ratio by following raw material:
1 part of the olivine sand of≤1.5mm, 0～0.28 part of 200 purpose olivine sand
0～0.4 part in the magnesia of≤1.5mm, 0.14～0.6 part in 200 purpose magnesia
0.1～0.5 part in coke, 0.1～0.3 part in charcoal
0.07～0.35 part of spent pulping liquor.
The manufacture method of lightweight forsterite brick is as follows:
1) with olivine sand and magnesia respectively through the crusher Mechanical Crushing, after the screening of 1.5mm screen cloth, make the olivine sand of granularity≤1.5mm and the magnesia of granularity≤1.5mm, getting wherein, a part is processed into 200 purpose fine powders respectively with ball mill; Coke and charcoal are also made respectively≤granularity of 1.5mm;
2) by the weight part proportioning in the prescription, take by weighing the particulate material of olivine sand, magnesia, coke and charcoal, add sand mill and did mixed 3～5 minutes, add spent pulping liquor then, wet mixing 3～5 minutes adds 200 order olivine sands and 200 order magnesia powders again, mixes 8～10 minutes;
3) material that mixes is added in the mould, on 200 tons～100 tons friction presses, add and be pressed into base;
4) base substrate more than 24 hours, is sent into the dry kiln drying 25～35 ℃ of following seasoninies, 100～120 ℃ of dry kiln hot-wind inlet temperature, 40～60 ℃ of temperature outs are not less than 16 hours time of drying;
5) dried base substrate is sent in the tunnel furnace, heated up, in 1350～1450 ℃ of insulations of temperature 3～5 hours, cooling cooling;
6) cooled goods are through cutting mill machine-shaping.
In process of production, select MgO 〉=43%, SiO for use
2〉=38% olivine sand; And the magnesia of MgO 〉=87%.
When raw material pulverizing is sieved, allow in particle or the fine powder above the particle of granularity or fine powder and exist, but the granularity upper limit tails over and is not more than 5% and is qualified particle or fine powder.
Drying is a key link, be blank deformation, the cracking avoid the dry sharply dehydration of light cinder brick to cause, so base substrate is should be at 25～35 ℃ of natural drying at room temperature more than 24 hours after the moulding, when winter, room temperature was low, need to carry out, and then send into the dry kiln drying at kiln.100-120 ℃ of control dry kiln hot-wind inlet temperature, between temperature out 40-60 ℃, general dry kiln length is not less than 24 meters, and go-cart is 40-70 minute/car at interval, is not less than 16 hours time of drying, and base substrate middle part, dry back moisture is not more than 10%.
Burning till is a link making most critical.Because blank strength is low, the mode that stacks bricks of the brick of therefore on stacking bricks, having taked to build a framework.Cause is compound combustion agent (coke and charcoal) the method brickmaking of taking.Therefore can incendiary material burnout the internal structure decisive role after brick is burnt till in burning till.Narrower because of the firing range of peridotites goods, be to widen firing range, and lightweight peridotites brick self blank strength is just low, so firing range is narrower by the amount that adds magnesia, wayward, the requirement to temperature on burning till is strict more.We burn till under strong oxidizing atmosphere by repeatedly repetition test is definite at last, and also promptly at coefficient of excess air 1.7-2.0, firing temperature 1350--1450 ℃ is incubated 3～5 hours, and total firing time from being warmed up to cooling greatly about 104 hours, can make finished product.
The invention has the beneficial effects as follows: forsterite brick of the present invention is a kind of with forsterite 2MgOSiO
2As the refractory materials that essential mineral is formed, adopt olivine sand and magnesia to make, make goods be weakly alkaline; Owing to added incendiary material coke and charcoal, base substrate is in sintering process, and the incendiary material burning forms pore, and the goods void content increases, and the weight of goods alleviates relatively, and thermal conductivity descends, and has improved heat insulation effect; 1000 ℃ of coefficient of thermal expansions of goods are only about 1.0, and are not yielding when high temperature uses, and intensity satisfies service requirements; Lightweight forsterite brick, because of its weakly alkaline, avoided because high temperature caused and working lining basic brick generation acid-base reaction, improved the work-ing life of alkaline working lining brick reserve lining light heat-insulation brick, thereby alleviate its damage degree and speed, reach 1540 ℃ even higher in temperature, still can use.
