Description

A kind of blast furnace iron notch anhydrous micro- titanium heap buildup and preparation method thereof
First, technical field：
The present invention relates to a kind of fireproof material for blast furnace iron outlet, and in particular to a kind of anhydrous micro- titanium heap of blast furnace iron notch Buildup and preparation method thereof.
2nd, background technology：
Micro- titanium heap buildup is the refractory material for blocking blast furnace iron notch, and can be divided into has the micro- titanium heap buildup of water and anhydrous micro- Two major class of titanium heap buildup.There is the micro- titanium heap buildup of water to be mostly used in the medium and small blast furnace that top pressure is relatively low, strengthening smelting degree is not high, it is anhydrous Micro- titanium heap buildup is mostly used on the large and medium-sized blast furnace that top pressure is higher, strengthening smelting degree is high.It is micro- in the blast furnace operation of steel plant Titanium heap buildup acts like that valve is the same, decide the envelope of blast furnace molten steel with it is stifled.So micro- titanium heap buildup answering in steel plant With very extensive and important.
With the continuous progress of ironmaking technology, large blast furnace is most using high wind pressure, high top pressure, Gao Yeqiang, Wind Volume, richness The new technologies such as the big injection of oxygen.Medium and small blast furnace is after strengthening smelting, day number of casts increase, and eliminates and put slag technique；Greatly Type blast furnace is also big because of its iron, and the requirement to the micro- titanium heap buildup quality of tapping hole is higher and higher.The micro- titanium heap of blast furnace iron notch When buildup blocks, go out in Tie Tong road to fill completely micro- titanium heap buildup, and mud drum is formed in cupola well, tapping hole is made to maintain enough Depth；Micro- titanium heap buildup is required to maintain stable aperture when tapping a blast furnace, is tapped a blast furnace uniformly；After having gone out iron, a large amount of coke are avoided as far as possible It is sprayed with the mucus of semi-molten.The tapping hole of daily blast furnace repeated multiple times will be opened and fill, red-hot molten iron and slag liquid To tapping hole micro- titanium heap buildup generation reason and chemical erosion.If micro- titanium heap buildup is of poor quality, when use, is just present with damp iron Mouth, shallow iron mouth, disconnected iron mouth, race are flowed greatly, depressurized, leaking informaton, burning out the series of technical such as casthouse equipment, influence normally to produce, Even cause personal injury accidents.It is therefore desirable to tapping hole has with the superperformance that micro- titanium heap buildup should have：A, plasticity and Caking property is good, easily gets into and fills up tapping hole passage；B, the porosity is suitable, convenient for discharging moisture and gas during drying；C, height Warm volume contraction is small, can avoid cracking；D, sintering character is good, and intensity is high, resistance to erosion and resistant to corrosion；E, the performance that is open is good Good, tapping machine drill mouth is easy；F, environmental pollution is small；G, there is high refractoriness.
At home, in recent years since Under Different Concentrate Supplementing Level improves, the quantity of slag is reduced, and along with the fragile slag tuyere of slag is put, is sent out It makes trouble therefore more, many iron-smelters have stopped putting slag operation, and all slag iron solution are all discharged from tapping hole, and are tapped a blast furnace day Number has different degrees of increase.Micro- titanium heap buildup early stage used in stifled iron notch is most of be with there is the micro- titanium heap buildup of water, be with Coke powder, clay, bauxite clinker, carborundum, sericite, house coal tar are primary raw material, and water stirring is added to roll.This micro- titanium There are general bulk density is small, sintering character is poor, sintering shrinkage is high, be also easy to produce crackle, resistance to slag iron aggressivity is poor, goes out for heap buildup The coke that iron mouth passage easily expands, period of tapping a blast furnace is red-hot easily sprays, goes out the defects of unnet iron, stifled incessantly iron mouth, so as to influence The normal production of blast furnace.In order to safeguard tapping hole, some takes increasing and beats mud amount, and certain depth baking is crept into before tapping a blast furnace, It the methods such as opens with small diameter drill bit brill, but all can not fundamentally find out the method solved the problems, such as, effect is undesirable.China it is big Type blast furnace generally only sets 1 accident cinder notch and 14 tapping holes, and there are many slag iron amount that tapping hole is discharged daily.Meet large-scale height Stove is to the quality requirement of the micro- titanium heap buildup of tapping hole, it is necessary to use anhydrous micro- titanium heap buildup.Anhydrous micro- titanium heap buildup is generally with firm Jade, carborundum combination silicon nitride, coke powder, high-quality bonding clay etc. are primary raw material, while with addition of different additives, use anthracene Oil, washing oil, tar are prepared as bonding agent.This micro- titanium heap buildup is as a result of high-quality high pure raw material, and with carbonaceous Raw material is bonding agent, and slag corrosion resistance can be good, can extend tapping hole tapping duration, reduce the number of casts；But because existing Its dispensing is stringent, beats that mud pressure is high, of high cost, tapping outlet is difficult, single beats mud amount (it is 50 that medium and small blast furnace beats mud amount every time greatly ~70kg, large blast furnace be 400~500kg), pollute environment a series of problems, such as, bring adverse effect to production and application.
At abroad, each main production iron country all attaches great importance to blast furnace iron notch with the quality of micro- titanium heap buildup, have special Research institution, such as Kawasaki of Japan, Nippon Steel, the refractory material research institute of Ukraine, the company of Bethlehem in the U.S. is equipped with The micro- titanium heap buildup technology group of stifled iron notch.At present, they are mainly based on anhydrous micro- titanium heap buildup, anhydrous micro- titanium heap originally Buildup is all to make bonding agent with tar, but tar can generate smog in use, and aggravating working environment influences worker's body and mind and is good for Health.The states such as Japan, US and European, it is the anhydrous tapping hole of bonding agent with micro- titanium heap buildup to have developed using resin, this micro- Titanium heap buildup not only eliminates the environmental pollution made bonding agent with tar and generated, and energy quick-hardening, micro- titanium accumulation material list consumption Reduce (such as Chiba, Japan 4500m3The micro- titanium heap buildup consumption of blast furnace ton iron only has 0.25kg/t), substantially increase anhydrous micro- titanium heap The performance of buildup.In addition to being improved in terms of to bonding agent, nippon also developed the micro- titanium heap of alkaline anhydrous tapping hole Buildup.This tapping hole with the apparent porosity of micro- titanium heap buildup be 25~32%, 1450 DEG C of high temperature break resistant intensities be 3.2~ 4.5MPa reaches the 3800m of 0.15MPa in top pressure3It is tried out on blast furnace and obtains good using effect.Britain also successively develops SiO2Micro- titanium heap buildup, siliceous material content have reached 64~68%, and anthracite 12.8%, tar 16.6% is heated to 1250 DEG C, compressive resistance reaches 4.08MPa after 2h.In order to solve the problems, such as that anhydrous micro- titanium heap buildup tapping outlet is difficult, Japan in Plunger method tapping outlet is had developed within 1985, is had a better effect.
Blast furnace is mainly made of with micro- titanium heap buildup aggregate, powder and bonding agent, and wherein bonding agent plays vital Effect.At present, domestic and international blast furnace is mainly tar, carbolineum or phenolic resin with the bonding agent of micro- titanium heap buildup, and containing has The carcinogen such as harmful benzene, benzoin, coal tar and coal tar pitch amount to addition and account for 20% or so in micro- titanium heap buildup, this Containing a large amount of strong carcinogen-benzoins in bonding agent, volatilized with heating using the tobacco of process, seriously affect operating personnel Health.179 DEG C of benzoin fusing point, 475 DEG C of boiling point, it means that micro- titanium heap buildup is used in sintering process, except mud drum It is outer to locate sub-fraction burn-up, it is most to be come out by fraction, since in-furnace temperature and pressure are much larger than outside stove, so benzoin is just It has been discharged to from blast furnace iron notch outside stove in air, the aerosol of harmfulness bigger is combined to form with the corpuscle in air, and Due to its own quite high temperature, make it more active in air, to the extent of injury bigger of environment.1st, 2- types benzoin It is strictly to control the chemical products used, research shows：Benzene in air and pyrene content often increase by 1%, caused by lung cancer mortality Increase by 5%.Therefore, the use of developed country strictly controls benzoin content high pitch, carbolineum, tar combination product；And For micro- titanium heap buildup that phenolic resin combines, due to the presence of benzene and formaldehyde, also there are certain pollution, and resin to environment With reference to micro- titanium heap buildup setting rate it is too fast, cause that the application operability of micro- titanium heap buildup is poor, generates disconnected iron mouth using process The problems such as.
In conclusion exploitation novel high-performance, pollution-free environmentally friendly blast furnace iron notch are had become with anhydrous micro- titanium heap buildup as state The Development Trend of inside and outside technical field of refractory materials.
