Description
Technical field
The present invention relates to production field of mineral wool, be specifically related to a kind of centrifugal mineral wool utilizing blast furnace hot molten slag and produce
Line.
Background technology
Mineral wool is that to utilize industrial waste slag (blast-furnace cinder etc.) be primary raw material, slag through fusing, quenched after qualified
Melt (1400～1500 degree) imports in centrifuge, and falls on Centrifugal rolling surface, thus being centrifuged that high speed centrifugation roller produces
Got rid of under the effect of power and made mineral wool fiber；Mineral wool fiber is blown into by the high velocity air simultaneously coordinating the vane ejection in centrifuge
In cotton collecting machine (high velocity air of vane ejection Centrifugal rolling axially on, along Centrifugal rolling surface flow at high speed).Ore deposit in cotton collecting machine
Cotton fiber is gathered on cotton collecting machine guipure formation mineral wool felt under negative pressure wind swabbing action.Mineral wool have light weight, heat conductivity little,
The feature such as do not burn, mothproof, inexpensive, corrosion-resistant, chemical stability is good, sound absorbing capabilities is good, thus adiabatic in the filling of building,
The aspects such as sound absorption, sound insulation and various heat power equipment are stuffed heat insulated have substantial amounts of application.
Mineral wool traditional manufacturing technique is furnace cupola technique.The work process of furnace cupola is: first loaded by a certain amount of coal
As bed coke in stove, its height is typically more than one meter.After igniting, bed coke is added to specified altitude, from air port to bed coke
End face is bed coke height.Then by the melting rate of stove by the limestone prepared, metal charge and coke charge the most in batches from
Charge door adds.Furnace charge end face edge under charge door is kept during whole blow-on.The air same end in air port blasts stove
Burnt generation combustion reaction, the high-temperature furnace gas of generation flows up, and heats furnace charge, and makes first metal furnaces on bed coke end face
Material fusing.Ferrum after fusing drops in during dropping to cupola well, is heated further by high-temperature furnace gas and red-hot coke, this
Process is the most overheated.Along with the burning of bed coke is become estranged the fusing of metal charge, the bed of material is gradually reduced.After every batch is load melting, fuel
Being supplemented by additional coke charge, make bed coke height be kept essentially constant, whole fusion process is carried out continuously.Limestone in furnace charge
Calx and carbon dioxide is resolved under the effect of high-temperature furnace gas.Calx is basic anhydride, it can and coke in ash and
The acidic materials such as impurity in furnace charge, metal-oxide are combined into the slag that fusing point is relatively low.The slag of fusing also drops to cupola well,
And float on molten iron.In furnace cupola, carry out the burning of bed coke, the transmission of heat and 3 important mistakes of metallurgical reaction simultaneously
Journey.
The preparation process of tradition furnace cupola technique produces one ton of mineral wool product averagely need to consume the energy about 550 kilograms mark
Quasi-coal (includes Jiao, electricity etc.).Energy consumption cost accounts for more than the 30% of factory cost, causes the selling price of mineral wool product can not to be in any more,
General all more than 2500-3200 yuan/ton, become mineral wool product be difficult to enter bottleneck problem that construction market highlights the most it
One.One of key of selling price of mineral wool product to be reduced is to reduce its energy consumption.Although by using one in traditional handicraft
A little new techniques (such as heating air-supply, oxygen-enriched blasting etc.) also can reach energy-conservation purpose, but the limited extent lowered consumption.
And blast furnace hot molten slag itself has the highest temperature (1400-1600 DEG C), its average heat content is about 1670MJ/t,
Belong to the residual heat resources of high-quality, there is the highest recovery value.Owing to blast furnace cinder is had many uses, therefore slag energy return
Receiving principle is not only to reclaim its residual heat resources, and the recycling of slag to be easy to, while making full use of waste residue sensible heat,
Produce mineral wool, cinder microcrystalline glass etc. and there is the building material product of relatively high added value；But at present, domestic and international blast furnace cinder is many with water
The method of quenching is main, and heat cannot recycle.Therefore, use blast furnace hot molten slag directly to prepare mineral wool and advantageously account for above-mentioned technology
The problem being individually present in field, it is achieved that the energy-saving and cost-reducing and blast furnace hot molten slag heat in mineral wool preparation process recycles
Organic unity, takes full advantage of the heat of blast furnace hot molten slag, is one of current hot spot technology studied.
On the other hand, centrifuge is also the key equipment in mineral wool production process, and it is to determine wool production and quality
Key factor, in current mineral wool production process, the most ripe, advanced centrifuge is four roller centrifuges, and its Centrifugal rolling is four,
Including the Centrifugal rolling being sequentially distributed from top to bottom, No. two Centrifugal rollings, No. three Centrifugal rollings and No. four Centrifugal rollings.Outside each Centrifugal rolling
Vane is arranged in side, will be blown in cotton collecting machine by getting rid of the mineral wool fiber made by high speed centrifugation roller.Current for producing mineral wool
The outer surface of the Centrifugal rolling of centrifuge is smooth arc surface；Owing to the outer surface of Centrifugal rolling is smooth arc surface, when molten
After body drop is on the outer surface of Centrifugal rolling, melt is positioned on Centrifugal rolling surface, and between melt and the outer surface of Centrifugal rolling
Adhesive force is the best, and this high velocity air that part melt being attached on Centrifugal rolling surface is easily sprayed by vane directly blows
From, and the melt blown off will quickly cool down after separating with Centrifugal rolling, harden formation slag ball, and cannot produce at high speed centrifugation roller
Centrifugal action under got rid of and made mineral wool fiber, the fibroblast rate thus resulting in centrifuge reduces (the fibroblast rate present off scheming
Generally between 60% to 70%).The more important thing is, owing to the outer surface of Centrifugal rolling is smooth arc surface, this not only makes to melt
Adhesive force between body and the outer surface of Centrifugal rolling is the best, and is attached to the melt on Centrifugal rolling surface and will join together, because of
And under the centrifugal action that high speed centrifugation roller produces, being attached to the melt on Centrifugal rolling surface is easily thrown out of, and is thrown out of
Melt granules bigger than normal, homogeneity is the best, causing Centrifugal rolling to get rid of the mineral wool fiber prepared, thick and short (fibre diameter is big, fiber
Length is short, and the average diameter of mineral wool fiber prepared present off scheming is generally below 9 microns), affect mineral wool quality.
