Referring to figs. 1 through Fig. 6, anti-leakage device for iron runner of iron making blast furnace comprises shell of blast furnace cooling stave protector 4 and molten iron guiding device 7.
Shell of blast furnace cooling stave protector 4 is fixed on the below of blast furnace taphole 2, is positioned at shell of blast furnace 12 outsides and connecting leg protector 11 tops, and links into an integrated entity by various mode of connection (such as welding, riveted joint etc.) and shell of blast furnace 12.Shell of blast furnace cooling stave protector 4 can have the shape corresponding with the shape of blast furnace with the part blast furnace combination, and for example, the bound fraction of shell of blast furnace cooling stave protector 4 can be lune according to the blast furnace radian.Be provided with cell body in shell of blast furnace cooling stave protector 4, sidewall center, the described cell body outside is formed with opening.
Be provided with cell body in molten iron guiding device 7, the opening of the cell body opening of molten iron guiding device 7 and shell of blast furnace cooling stave protector 4 links into an integrated entity by various mode of connection (such as welding, riveted joint etc.).Preferably, the cell body opening lowest point of molten iron guiding device 7 is corresponding with the cell body opening lowest point of shell of blast furnace cooling stave protector 4.Molten iron guiding device 7 can be supported by one or more molten iron guiding device strut members 8, along the derivation that stretches out of blast furnace main channel direction.
In order to protect the cooling wall linking tube of blast furnace; anti-leakage device for iron runner of iron making blast furnace also comprises connecting leg protector 11; this connecting leg protector 11 is fixed on blast furnace taphole 2 belows; be positioned at cooling wall linking tube 10 tops of blast furnace, and link into an integrated entity by various mode of connection (such as welding, riveted joint etc.) with shell of blast furnace 12 and the shell of blast furnace cooling stave protector 4 of blast furnace taphole 2 belows.Therefore, connecting leg protector 11 also can play the effect of supporting molten iron guiding device 7, that is, connecting leg protector 11 can support molten iron guiding device 7 with one or more molten iron guiding device strut members 8.
Molten iron leakproof high temperature protection material 5 as substrate, forms groove form from high to low with the inside of the interior cell body of building cell body that the formula mode fills shell of blast furnace cooling stave 9 and molten iron guiding device 7, is convenient to derive leak iron.
Molten iron leakproof high temperature protection material 5 can obtain in such a way: take phosphoric acid and Tai-Ace S 150 composite solution as wedding agent; with chamotte or three grades of high aluminas for gathering materials; add weight-reducing material (for example floating pearl); compound moldable with addition of bond fireclay and admixture modulation formation half lightweight, as molten iron leakproof high temperature protection material 5.
The relevant compound moldable physical and chemical index of half lightweight is as shown in the table:
For the molten iron leakage situation at Real-Time Monitoring blast furnace taphole 2 places, also can be at the shell of blast furnace cooling stave protector 4 inner measuring points that thermopair 6 is installed.Molten iron temperature is about 1450 ℃ during blast furnace casting, will solidify no longer mobilely when molten iron temperature drops to 1150 ℃ of left and right sides, therefore can select the thermopair 6 of temperature measurement range about 1000 ℃～1300 ℃.Thermopair 6 can be armoured thermocouple or platinum wire type thermopair.
Specifically, the measuring point of fixed installation thermopair 6 below the cell body inside center of shell of blast furnace cooling stave protector 4.The galvanic couple silk that can adopt diameter 6mm steel pipe to entangle thermopair 6 extends to the cell body central opening position of shell of blast furnace cooling stave protector 4; so that the measuring point of thermopair 6 is arranged in the molten iron leakproof high temperature protection material 5 of filling the cell body inside of shell of blast furnace cooling stave protector 4, thermopair 6 is connected to the monitoring and alarming system that is installed in the blast furnace master control room by the galvanic couple data line.
Can sum up according to the principle of work of anti-leakage device for iron runner of iron making blast furnace of the present invention as follows:
1, during blast furnace casting molten iron temperature about 1450 ℃, the impact of liquid body flow characteristics and action of gravity, molten iron preferentially flows to low-lying place.When molten iron temperature will solidify during at 1150 ℃ no longer mobile.Simultaneously; because molten iron high temperature is easily to the melting of steel member; became one after solidifying; so at the easy drain region of blast furnace main crude pig iron mouth shell of blast furnace cooling stave protector 4, molten iron guiding device 7 and connecting leg protector 11 are installed; and with compound moldable being filled in shell of blast furnace cooling stave protector 4, the molten iron guiding device 7 of half lightweight, make groove form from high to low.In case molten iron occurs to be revealed; molten iron will be carried by shell of blast furnace cooling stave protector 4; and under the compound moldable protection that builds up cell body of half lightweight, insulation, flow out from molten iron guiding device 7 rapidly, and then play the effect of protection shell of blast furnace cooling stave 9, cooling wall linking tube 11.
2, because the hot properties of molten iron; at the measuring accuracy higher thermopair of the inner installation of half lightweight compound moldable (molten iron leakproof high temperature protection material 5) temperature measurement range at 1000 ℃～1300 ℃; when molten iron flows through the compound moldable groove of half lightweight; cause temperature sharply to raise; thermopair is with the monitoring and alarming system of temperature variation data transmission in the blast furnace master control room; the monitoring and alarming system alarm, and then check processing by the post personnel.
Further specify making and installation method according to anti-leakage device for iron runner of iron making blast furnace of the present invention below in conjunction with accompanying drawing.
The first step is made connecting leg protector 11.Leak the quantity of shell of blast furnace cooling stave 9 in iron zone and the position of cooling wall linking tube 10 according to blast furnace main channel 1 bottom; adopt steel plate to make the protection box body of predetermined length and width high (for example 2.8 meters * 0.6 meter * 0.6 meter); one side of protection box body is connected by various mode of connection (such as welding, riveted joint etc.) with shell of blast furnace 12, protects the bottom of box body be fixed (referring to Fig. 6).
Second step is made shell of blast furnace cooling stave protector 4.Above connecting leg protector 11, adopt steel plate to make the cell body of the shell of blast furnace cooling stave protector 4 of predetermined length and width high (for example 2.8 meters * 0.5 meter * 0.6 meter); the cell body of shell of blast furnace cooling stave protector 4 is inboard to be connected with shell of blast furnace 12; the cell body top of shell of blast furnace cooling stave protector 4 is connected with the steel tank cell body of tap drain 1; sidewall center, the cell body outside at shell of blast furnace cooling stave protector 4 forms opening, described opening and cell body bottom (for example 0.2 meter) (referring to Fig. 1 to Fig. 4) spaced a predetermined distance from.
