Below in conjunction with drawings and Examples, the present invention is further described:
As shown in Figure 1, hotblast stove constructional method under cryogenic, comprises the following steps:
A, build hotblast stove housing 1, and at hotblast stove housing 1 external parcel housing thermal insulation layer 11;
The first layer bearing 21 is installed in B, bottom in hotblast stove housing 1 overhead preset height, and sets up isolating frame 22 on above-mentioned the first layer bearing 21; Base insulating layer 23 is laid on described isolating frame 22; The first layer keeping warmth space 2 is formed in the bottom of above-mentioned isolating frame 22;
C, in described the first layer keeping warmth space 2, arrange steam heat radiation rack 6, described steam heat radiation rack 6 is communicated with steam hose 61, by external steam room to steam hose 61 and steam heat radiation rack 6 delivering vapor; Described steam heat radiation rack 6 is connected with the lifting device 63 at hotblast stove top by hoist cable 62, and lifting device 63 is sling unsettled for steam heat radiation rack 6, utilizes steam to heat the first layer keeping warmth space 2;
D, stirring make refractory mortar;
E, the refractory materials comprising refractory brick and refractory mortar is transported to described the first layer keeping warmth space 2 stores;
F, reach after construction requirement until refractory temperatures, utilize refractory materials to build hotblast stove internal structure at the first layer keeping warmth space 2;
G, after the internal structure constructed fully is solidified, utilize lifting device 63 upwards to promote preset height original isolating frame 22, and hotblast stove housing 1 below isolating frame 22 installs second layer bearing 211, isolating frame 22 is placed on second layer bearing 211; Isolating frame 22 is laid base insulating layer 23, and the space between the below of the isolating frame 22 on above-mentioned installation second layer bearing 211 and former the first layer bearing 21 position forms second layer keeping warmth space 3; With lifting device 63, steam heat radiation rack 6 is upwards risen to second layer keeping warmth space 3 to heat; The internal structure of building hotblast stove second layer keeping warmth space 3 is continued according to the method that above-mentioned steps D, E, F are same;
H, repeat above step, to form third layer to n-th layer keeping warmth space and build corresponding hotblast stove internal structure, until whole hotblast stove internal structure has been built.
Constructional method of the present invention first builds hotblast stove housing 1, then at closure periphery parcel housing thermal insulation layer 11.Described housing thermal insulation layer 11 is first worn one by one by flax silk woven bag with 8# iron wire, and length is the girth of furnace shell, then hangs on the steel nail of furnace shell spot welding in advance, and quantity and the position of steel nail are arranged according to practical situation, usually adopts the often average welding of circle 12 steel nails; And then with iron wire, woven bag from coil to coil is tied, namely complete a circle woven bag and lay; According to same method, continue to lay woven bag above this circle woven bag, the position needs staggered overlap joint 150mm that every layer of woven bag is adjacent; Finally cover one deck plastic flame cloth in woven bag periphery, namely housing thermal insulation layer 11 has wrapped up.Housing thermal insulation layer 11 can be disposablely to be wrapped up completely by whole hotblast stove housing 1, also can be according to circumstances first wrap up a part, after its interior construction completes, then wrap up another part.The effect of housing thermal insulation layer 11 is to play heat-blocking action, reduces heat trnasfer inside and outside housing.
Then in hotblast stove housing 1 inside, the first layer bearing 21 is installed, and isolating frame 22 is set up on the first layer bearing 21, the effect of the first layer bearing 21 provides support a little for isolating frame 22, and its embodiment can be adopt welding or be threaded to wait usual way on hotblast stove housing 1, install one to enclose bearing.The height installed is selected according to practical situation, if envrionment temperature is very low, the first layer bearing 21 can be arranged on overhead lower position, like this after putting up isolating frame 22 and base insulating layer 23, the first layer keeping warmth space 2 formed between isolating frame 22 and housing thermal insulation layer 11 is relatively little, is conducive to temperature increase in hotblast stove; If envrionment temperature is not low especially, the first layer bearing 21 can be arranged on higher height, form larger the first layer keeping warmth space 2, with accelerating construction progress.Common, the mounting height of the first layer bearing 21 is selected between 3 ~ 5 meters.
In the first layer bearing 21, the quantity of bearing is selected according to practical situation, as long as can reach stable support isolating frame 22.
Isolating frame 22 utilizes steel pipe, steel plate is built and is formed and be arranged on the first layer bearing 21, building method can adopt method of the prior art, such as utilize steel pipe and scaffold clasp to connect and connect setting support, according to circumstances isolating frame 22 can directly be placed on the first layer bearing 21, or for greater safety, utilize bolt fasteners to lock isolating frame 22 and the first layer bearing 21 tie point.The base insulating layer 23 of 8mm rubber and flax silk woven bag composition is laid on isolating frame 22.
Arrange steam heat radiation rack 6 at the first layer keeping warmth space 2, steam heat radiation rack 6 can adopt stainless-steel pipe welding metal radiator element to make, and is communicated with steam hose 61, and the steam sent here by steam hose 61 by external boiler room or vaporium.Utilize heat trnasfer or heat radiation principle, make the first layer keeping warmth space 2 internal temperature increase.Described steam heat radiation rack 6 is connected with the lifting device 63 at hotblast stove top by hoist cable 62, and lifting device 63 can drive steam heat radiation rack 6 promote or land, and slings in position, heat unsettled for steam heat radiation rack 6 the first layer keeping warmth space 2.
Stir and make refractory mortar, refractory mortar forms fire-resistant slurry powder by fine solid particle, powder, bonding agent, additive etc., forms muddy and have cementability after the fully stirring that adds water.The refractory materials such as refractory mortar and refractory brick stores through winding tower 8 and the first layer keeping warmth space 2 sending defeated corridor 5 to deliver to hot work in progress.Utilize the heat that steam heat radiation rack 6 brings, the temperature of refractory mortar and refractory brick can get a promotion, and reaches after execution conditions just can start to build internal structure until refractory temperatures.
After the internal structure constructed fully is solidified, utilize lifting device 63 to promote certain altitude original isolating frame 22, the hotblast stove housing 1 then below isolating frame 22 installs second layer bearing 211.Isolating frame 22 needs the height of lifting identical with aforesaid principle, usually selects 3 ~ 5 meters.The method of installing second layer bearing 211 is identical with aforesaid installation the first layer bearing 21 method.Adopt aforementioned same method to be placed on second layer bearing 211 by isolating frame 22, and lay base insulating layer 23.Second layer keeping warmth space 3 is formed between the below of isolating frame 22 and original the first layer bearing 21 position.Utilize lifting device 63 that steam heat radiation rack 6 is risen to second layer keeping warmth space 3 to heat, continue the internal structure of building second layer keeping warmth space 3 according to aforementioned same method.
Repeat above method, form third layer and build corresponding internal structure, until whole hotblast stove internal structure has been built to n-th layer keeping warmth space.
Adopt constructional method of the present invention, the hotblast stove built can reach basically identical quality level and work-ing life compared with completing with under normal temps.In actual production, according to working-yard particular case, can when temperature be higher by day, need not or few steam with heating, to reduce expenses.
