Abstract
The invention belongs to the technical field of refractory material production, and particularly relates to a production technology for bauxite homogenized-material mud blanks. The production technology includes the steps as follows: (1) breaking bauxite raw ore and deironing to obtain a material A; (2) adding aluminium polychlorid, lignocellulose and water in the material A, conducting ball-milling to obtain a mud material B; and (3) dewatering the mud material B so as to form bauxite homogenized-material mud blank. Due to the common action of the aluminium polychlorid and the lignocellulose, the bauxite homogenized-material mud blank obtains high plasticity and high strength and avoids deformation, cracking and dropping.
Description
Technical field
The invention belongs to the refractory raw material production technical field, be specifically related to a kind of production technique of bauxitic clay homogenization material moulded pottery not yet put in a kiln to bake.
Background technology
Usually the production technique of wet production bauxitic clay homogenization material is: ore reduction → wet method is levigate → filter mud → and squeeze mud and become base → drying → sintering.Because bauxitic clay attribute raw material, the moulded pottery not yet put in a kiln to bake of extruding through bat extruder still contains the moisture content of 16-19%, so blank strength is relatively poor, very easily be out of shape, ftracture, come off, not only give to pile up and caused difficulty, next procedure such as also should not carry out drying, burn till, scrap rate has a strong impact on output up to 40% simultaneously.For addressing this problem, each manufacturer all adopts interpolation spent pulping liquor (wooden calcium sulfonate) to solve this problem at present, but DeGrain is particularly produced AL
2O
3The bauxitic clay homogenization material that content is higher (as L-88, L-90, L-92) still has the scrap rate about 30%.
Summary of the invention
The object of the present invention is to provide a kind of production technique of bauxitic clay homogenization material moulded pottery not yet put in a kiln to bake, the bauxitic clay homogenization material moulded pottery not yet put in a kiln to bake that this technology makes is indeformable, do not ftracture, do not come off.
The present invention is by the following technical solutions:
A kind of production technique of bauxitic clay homogenization material moulded pottery not yet put in a kiln to bake may further comprise the steps: (1) gets material A with the fragmentation of bauxitic clay rawore, deironing; (2) in material A, add polymerize aluminum chloride, lignocellulose and water, carry out ball milling and get pug B; (3) pug B dehydration aftershaping is a bauxitic clay homogenization material moulded pottery not yet put in a kiln to bake.
The consumption of described polymerize aluminum chloride is the 0.2-0.5% of material A weight, and the lignocellulose consumption is the 0.1-0.3% of material A, and the consumption of water is the 30-50% of material A weight.
Adopt jaw crusher or roll crusher fragmentation when broken in the described step (1), the particle diameter of broken back material is less than 5mm.
Time in the described step (2) during ball milling is 5-8 hour.
Adopt mud press when dewatering in the described step (3), dewatering time is 5-15min.
Adopting vacuum tightness in the described step (3) during moulding is that the vacuum bat extruder of 0.07-0.2Mpa pushes cutting.
Technology of the present invention has been added polymerize aluminum chloride and the lignocellulose as toughener in raw material, wherein polymerize aluminum chloride has the grinding aid effect, and can make bauxitic clay pug reunion enhancing, secure bond, plasticity-good; Lignocellulose is crisscross, reinforced action is arranged in pug, make the pug secure bond, and tool capillary " blood vessel " effect makes that the road drying process dewaters easily down, because the acting in conjunction of polymerize aluminum chloride and lignocellulose, make that bauxitic clay homogenization material moulded pottery not yet put in a kiln to bake plasticity-is good, intensity is high, distortion, cracking and obscission can not occur.
Polymerize aluminum chloride of the present invention and lignocellulose have very easily been bought on market and are cheap, one ton of bauxitic clay homogenization material of every production, the two total consumption is 0.3-0.8%, current market price is calculated, its cost is about 8-20 unit, and with high the comparing of spent pulping liquor cost that tradition is used, effect is remarkable, but also having grinding aid, diminishing and the effect of quickening exsiccant, economic benefit is very remarkable.
