Abstract
The invention discloses a preparation process of a permanent lining ladle castable. The preparation method comprises the following components in parts by weight: 58 to 62 parts of waste magnesite brick, 18 to 22 parts of ordinary bauxite, 14 to 16 parts of fine bentonite powder, 3 to 5 parts of aluminum oxide micro powder, 1 to 3 parts of mullite micro powder, 4 to 6 parts of fine fused magnesite powder, 1 to 2 parts of sodium hexametaphosphate, and 7 to 9 parts of water. The preparation process comprises the following steps: 1) selecting waste magnesite brick blocks, removing impurities, crushing, and transferring into a mixer based on the particle size ratio above and mixing for 5 to 10 minutes; 2) adding ordinary bauxite, fine bentonite powder, aluminum oxide micro powder, mullite micro powder and fine fused magnesite powder, and mixing for 15 to 25 minutes; and 3) adding sodium hexametaphosphate and water to continuously mix for 30 to 40 minutes, and then bagging.
Description
Technical field
The present invention relates to technical field of ferrous metallurgy, relate in particular to a kind of preparation technology of ladle permanent liner casting material.
Background technology
At present, worldwide, ladle permanent lining mainly contains two kinds of forms of construction work: the one, and the brick technique 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 material cost is high, it is numerous and diverse to work, labour intensity is large, and globality is also bad, makes ladle use the later stage to have security hidden danger; The latter's good integrity, labour intensity reduce to some extent, but higher to ingredient requirement, and construction technology more need to increase the equipment such as mould, stirrer and vibrating motor as complexity, increase stirring, cast, vibration, health, bake process, whole expense is still higher, and be subject to the conditionalities such as region humidity, temperature, apply and be restricted.
From the research mould material paper delivered and the mould material of actual use, the material that ladle permanent liner casting material adopts has corundum, spinel, High-Alumina, mullite etc., adopt above-mentioned material as ladle permanent liner casting material, not only increase material cost and ton steel cost, and caused the significant wastage of resource.From the related application of having announced, also there is the research and development such as the reclaimed materials that adopts useless brick ladle permanent linings, the bonding agent of selecting is cement, although this permanent liner has guaranteed working strength to a certain extent, but because at high temperature easily causing mould material performance, cement worsens the danger that exists ladle and wear bag.
Summary of the invention
The object of the invention is to propose a kind of preparation technology of ladle permanent liner casting material, this technique overcomes the defect of prior art, and by the proportioning of material component, make permanent liner prepared by this mould material at high temperature still there is higher intensity, and reduced production cost.
For reaching this object, the present invention by the following technical solutions:
A kind of preparation technology of ladle permanent liner casting material, the raw material of this mould material is made up of following component in weight part: useless magnesia brick 58-62 part, wherein particle diameter 8-12mm account for 30%, 8mm > particle diameter >=3mm account for 50%, 3mm > particle diameter >=1mm account for 20%; Conventional aluminium alumina 18-22 part, particle diameter≤1mm; Wilkinite fine powder 14-16 part, particle diameter < 0.074mm; Alumina powder 3-5 part, particle diameter < 0.074mm; Mullite miropowder 1-3 part, particle diameter < 0.074mm; Electrosmelted magnesite clinker fine powder 4-6 part, particle diameter < 0.088mm; Sodium hexametaphosphate 99 1-2 part; Water 7-9 part; Described preparation technology comprises the steps:
1) the magnesia brick piece material that will give up is chosen and removes after impurity broken, and puts into mixer mixing 5-10 minute by above-mentioned grain size proportion;
2) add conventional aluminium alumina, wilkinite fine powder, alumina powder, mullite miropowder, electrosmelted magnesite clinker fine powder, remix 15-25 minute;
3) add Sodium hexametaphosphate 99 and water, continue to mix after 30-40 minute, be packaged into bag.
The present invention has following beneficial effect:
1) the present invention will give up magnesia brick as major ingredient, realize the re-using of waste refractory materials, save energy, significantly reduce the cost of mould material, its blending powder has been carried out to a large amount of tests simultaneously, determine the collocation of above-mentioned the best, made to adopt the intensity of permanent liner prepared by this mould material to improve.
2) do not adopt cement, but adopt wilkinite; And be equipped with the combination of alumina powder+mullite miropowder+electrofusion magnesia powder, and can guarantee that mould material has enough withstand voltage and folding strengths at production temperature (1200 ℃), this mould material has certain resistance to fouling simultaneously, has guaranteed the smelting safety of ladle.
3) physical and chemical index of mould material of the present invention is for reaching: after 110 ℃ × 24h is dried, and compressive strength > 45Mpa, folding strength > 10Mpa.
