Abstract
The invention provides a preparation method of a non-stick aluminum castable. The non-stick aluminum castable comprises the following ingredients in parts by mass: 60 parts of platy corundum aggregate, 10 parts of alumina clinker powder, 6 parts of brown corundum, 9 parts of silicon micropowder, 5 parts of alumina micropowder, 10 parts of calcium aluminate cement and 0.5 parts of molten aluminum resistance additive. The preparation method comprises the steps of grinding the platy corundum aggregate into 5-3mm, 3-1mm and 1-0mm, grinding the alumina clinker powder into 180-mesh powder, ensuring that two persons are in the factory for material weighing and confirmation respectively during batching, feeding batched materials into a mixer, turning on the mixer for mixing for 5-8min, and carrying out detection and packaging. According to the preparation method of the non-stick aluminum castable, a specific protective layer is formed on the surface of a solidifying body after solidification to block air holes and prevent aluminum sticking; furthermore, an efficient high quality fireproof binding agent is added, the surface of the solidifying body is smooth; and slag is not hung more easily.
Description
Technical field
The present invention relates to a kind of making method of not sticky aluminium mould material, belong to cement technology field.
Background technology
In aluminium industry processed, the obnoxious flavour that produces in aluminium liquid essence grain thinning process, the havoc weave construction of mould material, sintering strength difficulty is large.Owing to producing aluminium ash in aluminium fusion process, knot corundum knurl, the element of metallic aluminium solution in refractory materials reacts, and impurity enters in aluminium alloy affects aluminium alloy quality.The adhesive rate of aluminium liquid, seepage capability is just not enough, is unfavorable for the work-ing life of refractory materials.
Summary of the invention
The invention provides a kind of making method of not sticky aluminium mould material, making method for the sticky aluminium mould material of above problem is the not sticky aluminium material feeding that aluminium and alloy industry develop specially, cannot not add stickyly aluminium composition especially, add a certain amount of radiation resistance material and neutrality material, there is Gao Timi, high strength, be not the character that aluminium and alloy molten solution soak, significantly can reduce the infiltration of molten metal to material.
For solving above technical problem, the invention provides following technical scheme: a kind of making method of not sticky aluminium mould material, described not sticky aluminium mould material comprises 60 parts, plate diamond spar aggregate according to mass ratio, 10 parts, bauxite clinker powder, Brown Alundum 6 parts, silicon powder 9 parts, alumina powder 5 parts, aluminous cement 10 parts, aluminum-resistant solution additive 0.5 part; Carried out brokenly by plate diamond spar aggregate pulverizing, raw material crushing becomes 5mm-3mm, 3mm-1mm, 1mm-0mm, and bauxite clinker is ground into 180 powder materials; Guarantee during batching that two people are in factory, people's weighing, a people confirms; Drop in stirrer by the material prepared, start is stirred, churning time 5 ~ 8min; Detect, pack.
Further, needed for described detection, project comprises: volume density, thermal conductivity, compressive strength, folding strength and Linear change rate.
Further, described detection required equipment comprises: stirrer, shaking table, vibratory screening apparatus, pressure testing machine, Intensity of Breaking Tester, High Temperature Furnaces Heating Apparatus, industrial balance, analytical balance, baking oven, 721 spectrophotometers, 6400 flame photometers.
The making method of this not sticky aluminium mould material that the present invention relates to, congealed solid surface after solidification defines the distinctive protective layer of one deck, has blocked pore, has prevented and be stained with aluminium.Add the fire-resistant bonding agent of high-efficiency high-quality in addition, make its congealed solid smooth surface, more difficult dross.The contact aluminium liquid positions such as the making method of sticky aluminium mould material is widely used in aluminium melting furnace, maintenance stove contacts aluminium liquid position, aluminium liquid holding furnace, aluminium liquid are two-mand ladle.Be particularly suitable for the integrated poured and rafifinal melting equipment furnace lining of casting machine preincubation stove.
