Abstract
The invention relates to a ramming material for a ladle permanent lining and a production method thereof. The ramming material comprises the following raw materials by weight: 5-95 parts of magnesia or olivine, 5-95 parts of alumina, 3-25 parts of clay or bentonite and 0.5-10 parts of an agglutinant. The method comprises the following steps: firstly, crushing and sieving the magnesia/olivine, the alumina and the clay; mixing the raw materials at the weight ratio; adding the agglutinant at the weight ratio and stirring to evenly mix; and packaging to obtain a finished product. The ramming material has low price, low cost, simple construction, good integrity and stable and reliable quality, and can be widely used in the ladle construction field.
Description
Technical field
The present invention relates to a kind of ladle construction and use material, particularly relate to a kind of ramming material for ladle permanent lining and preparation method thereof.
Background technology
At present, worldwide, ladle permanent lining mainly contains two kinds of forms of construction work: the one, and the brick technology of early stage wet method, the 2nd, the pouring technology of taking in recent years.The former needs high alumina brick or magnesia brick and chamotte joint filling, and the material cost height, work is numerous and diverse, labour intensity is big, and globality is also bad, makes ladle use the later stage to have security hidden danger; Latter's good integrity, labour intensity reduce to some extent, but it is higher to ingredient requirement, be confined to SiO2-Al2O3 system, and construction technology is more as the complicated equipment such as increase mould, stirrer and vibrating motor that need, increase stirring, cast, vibration, health, bake process, whole expense is still higher, and is subjected to conditionalities such as region humidity, temperature, applies being restricted.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of ramming material for ladle permanent lining and production method thereof are provided, and this method material cost is low, construction is simple, good integrity, and excellent property, steady quality is reliable.
In order to address the above problem, the present invention by the following technical solutions:
A kind of ramming material for ladle permanent lining, it is formed by the following raw materials in parts by weight mixed:
Magnesia or peridotites 5～95
Alumina 5～95
Clay or wilkinite 3～25
Agglutinant 0.5～10.
The grain size distribution of described magnesia or peridotites and alumina is, by weight ratio:
1-3mm 45～55
0.074-1mm 25～35
0-0.074mm 12～40。
Described clay or bentonitic granularity are 0-0.074mm.
Described agglutinant is that in silicate, phosphoric acid salt, borax, the boric acid one or more are compound.
A kind of production method of ramming material for ladle permanent lining, the concrete steps of this method are:
1) at first with magnesia or peridotites, alumina with add clay fragmentation, screening;
2) each raw material after the fragmentation is mixed in above-mentioned weight part ratio;
3) add agglutinant, mix;
4) pack goes out finished product.
Compared with prior art, the invention has the beneficial effects as follows:
1, raw materials cost is cheap, and the course of processing is simple, and end properties is good, and steady quality is reliable, and good market outlook are arranged.
2, very simple with product construction of the present invention, promptly do not need to resemble with brick and chamotte to build, also do not need to resemble and with mould material, stir cast vibration health baking, but the tamping that feeds intake gets final product.
Embodiment
Embodiment one
A kind of ramming material for ladle permanent lining, the weight part ratio of each raw material is: 55 parts in magnesia, 45 parts in alumina, 20 parts of clays, 3 parts of silicate agglutinants.
The production method of described ramming material for ladle permanent lining may further comprise the steps:
1) at first with magnesia/peridotites, alumina with add clay fragmentation, screening;
2) each raw material after the fragmentation is mixed in above-mentioned weight part ratio;
3) add agglutinant, mix;
4) pack goes out finished product.
Embodiment two
A kind of ramming material for ladle permanent lining, the weight part ratio of each raw material is: 5 parts in peridotites, 15 parts of 95 parts of wilkinites of alumina, 1 part of phosphoric acid salt agglutinant.
The production method of ramming material for ladle permanent lining is with embodiment one.
Embodiment three
A kind of ramming material for ladle permanent lining, it is formed by the following raw materials in parts by weight mixed: 95 parts in magnesia, 5 parts in alumina, 3 parts of clays, 6 parts of boric acid agglutinants.
The production method of ramming material for ladle permanent lining is with embodiment one.
Among the above embodiment, the grain size distribution of described magnesia or peridotites and alumina is, by weight ratio:
1-3mm 45～55
0.074-1mm?25～35
0-0.074mm 12～40。

The constructional method that employing the present invention carries out at the bottom of the ladle bag is:
1) foreign material in the peace and quiet bag are ajusted the brick cup mould;
2) at the thick asbestos plate of bag box hat upper berth, end one deck 10mm;
3), smash with brick and to pound about 65mm, be i.e. the thickness of one deck standard square at the thick ramming mass in one deck 90mm left and right sides, asbestos plate upper berth;
4) build bag end brick.
The constructional method that adopts the present invention to carry out ladle wall is:
1) is close to the thick asbestos plate of bag wall box hat shop one deck 10mm;
