Description
Technical field
The invention belongs to blast furnace ironmaking plastic refractory field, be specifically related to a kind of novel blast-furnace stemming and preparation method.
Background technology
Blast furnace is the main equipment of manUfaCtUre of pig iron, and after blast-furnace smelting iron, after being released by molten iron, carries out continuously to ensure to smelt from iron mouth, iron notch must be blocked, blocks the material of iron notch, be stemming.And iron notch is in life-time service process, all can have erosion, iron notch there will be reaming, cause flowing molten iron unstable, iron mouth shoals, and goes out unclean iron, even run the situations such as large stream, having a strong impact on production normally taps a blast furnace, and finally have impact on the work-ing life of blast furnace and the growth of output.
Summary of the invention
The object of this invention is to provide one and beat mud conveniently, iron-resistant water erosion, the stemming that molten iron discharging is stable and production method thereof.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of 5500m

As preferably of the present invention, described blast furnace mud is made up of the component of following weight part: zircon corundum 10 parts; Titanium nitride: 10 parts; Aluminium nitride: 8 parts; Agalmatolite rawore: 10 parts; Zirconium carbonate 1 part; Ball clay: 20 parts; Aluminum oxide powder 2 parts; Graphite Powder 99: 20 parts; Silicate 425 cement 1 part; Silicon nitride iron powder: 8 parts, pulverized anthracite 4 parts, resin-oatmeal: 6 parts; Polyether-modified organopolysiloxane: 0.05 part; Additional bonding agent: 15 parts.
As preferably of the present invention, the granularity of described aluminum oxide powder is < 325 order; The granularity of described pulverized anthracite is 200 orders.
As preferably of the present invention, this bonding agent is by the modify cement of tar by obtaining with sodium peroxide Hybrid Heating.As preferably, the benzopyrene content 50-100ppm of described modify cement.
As preferably of the present invention, described a kind of 5500m
3the preparation method of blast furnace mud, is characterized in that adopting following processing method to obtain: all above-mentioned raw materials are put into mixing pan, first pre-mixing 15 minutes; Then 80% of bonding agent total amount is added, wet stone roller 40 minutes; Add 20% remaining bonding agent, rewetting grinds 10 minutes; Through stemming microtome, then through mud extruder, squeeze mud shaping, load packing bag, be finished product; Squeeze mud temperature and be set as 70 DEG C.
Compared with existing stemming series products system, present invention adds aluminium nitride, reduce the wetting angle of molten iron and stemming, molten iron is not easily reacted with stemming, improve the ability of sulphur phosphorus in resistance to molten iron, the titanium nitride added improves the capacity of heat transmission of stemming, erosion resistibility, its to molten iron have inertia excellent properties, improve the anti-erosion erosion resistibility of stemming; After using technical scheme of the present invention, obtain one and beat mud conveniently, iron-resistant water erosion, the stemming that molten iron discharging is stable, the problems such as can solve current blast furnace uses the stemming iron notch caused of poor quality to shoal, not resistance to erosion, and not resistance to molten iron corrodes and stemming is seriously polluted.
