Description

A kind of novel environment friendly blast furnace mud
Technical field
The invention belongs to blast furnace ironmaking plastic refractory field, be specifically related to a kind of novel environment friendly blast furnace mud and preparation method.
Background technology
Blast furnace is the main equipment of manUfaCtUre of pig iron, and after blast furnace process ferrum, by molten iron after ferrum mouth is released, in order to ensure that smelting is carried out continuously, it is necessary to tapping hole is blocked, blocks the material of tapping hole, be stemming.And tapping hole is during life-time service, all can have erosion, tapping hole there will be reaming, causing ferrum mouth to shoal, flowing molten iron is unstable, goes out unclean ferrum, even run the situations such as big stream, have a strong impact on production and normally tap a blast furnace, and finally have impact on the service life of blast furnace and the growth of yield.And ferrum mouth is in inside burner hearth, temperature is high, and generally, people cannot be introduced into maintenance.
Stemming belongs to expendable consumed product, typically has only to service life reach two or three hours.Therefore, on the premise of meeting performance, present invention uses with rear blown-out shot mud, the gangue rawore stacked nowhere discarded during coal mining, reduce product cost, solve the problem that gangue solid waste is stacked nowhere simultaneously, also save other resource, belong to a kind of low-cost environment-friendly product.
Summary of the invention
It is an object of the present invention to provide a kind of low cost, resource reusable edible, also have the blast furnace mud of ferrum mouth maintenance function, this stemming can effectively utilize gangue raw material, and garbage reduces cost, can safeguard again tapping hole simultaneously；Additionally, add Glydoln2002 inside stemming, it is ensured that during stemming depositing before use, properties does not declines.
The above-mentioned technical purpose of the present invention has the technical scheme that a kind of blast furnace mud, it is characterised in that described blast furnace mud is made up of the component of following weight portion: with rear blown-out shot mud: 10 ~ 20 parts；Yttrium mullite: 5 ~ 15 parts；Gangue rawore: 10 ~ 20 parts；Modified ferro-magnesium-aluminum spinelle powder: 10 ~ 25 parts；Modified clay: 10 ~ 20 parts；Recycled graphite electrode powder: 10 ~ 33 parts；Thickening agent: 8 ~ 18 parts, asphalt powder: 3 ~ 8 parts；Glydoln2002:0.2 ~ 0.5 part；Additional bonding agent: 12 ~ 14.5 parts, nano-cellulose 0.1；Described thickening agent is the weight ratio 1:1 mixture of vanadium iron ore deposit and copper oxide.
Preferred as the present invention, the described granule that 1-0mm through crusher in crushing, need to be chosen with rear blown-out shot mud；Described yttrium mullite refers in mullite lattice the solid solution extraordinary mullite of yittrium oxide, and its yittrium oxide solid solubility is 2.5%；Described gangue rawore is the material peeled off of mining.
Preferred as the present invention, described modified magnesium-ferrum-aluminum Pre-synthesized spinel fine powder is 220 mesh, and chemical composition is magnesium oxide 10%, ferrum oxide 35%, aluminium oxide 53%, zirconium oxide 2%；Recycled graphite electrode powder is the electrode scrap of steel-making, wears into 325 mesh fine powders；Vanadium iron ore deposit is 325 mesh fine powders of technical grade content more than 80%；Copper oxide is the powder of 200 mesh；Asphalt powder carbon yield 40%, softening point 110 DEG C；Glydoln2002 is a kind of modifying agent, can prevent Organic substance from volatilizing, and ion exchange can be made bigger reversibility occur, after breeching, make stemming can return to original performance faster；Nano-cellulose is a kind of Biodegradable material, can increase the breathability during stemming uses.
Preferred as the present invention, this bonding agent is by the modified bonding agent obtained with sodium peroxide Hybrid Heating by tar.As preferably, the benzopyrene content of described modified bonding agent is not more than 100ppm.
In sum, the present invention compared with prior art, has advantage highlighted below and a beneficial effect:
The present invention is compared with existing stemming product, owing to adding magnesium-ferrum-aluminum Pre-synthesized spinel powder and thickening agent, can in use repair ferrum mouth, and promote to have repaired the sintering of ferrum mouth, prevent the function of tapping hole reaming again.
This product is compared with existing stemming, and after adding Glydoln2002, the holding time is long, and after long-term storage, properties does not declines；The nano-cellulose added can ensure that the breathability of stemming, will not form the spray rocket phenomenon of molten iron during use.
This product is lower than cost with existing stemming, selects the material of the low cost such as soft coal spoil, blown-out shot mud, hence it is evident that reduce the cost of stemming, be entirely capable of again meeting the needs that blast furnace normally produces；Adding modified clay, improve plasticity and the activity of stemming, to repairing, tapping hole is more favourable.
After using the present invention, tapping hole is maintained, and blast fumance is normal, and stemming prices has all saved cost for enterprise and user, and before can thoroughly changing current State of Blast Furnace, ferrum mouth shoals, and stemming is seriously polluted, high in cost of production problem.
