Abstract
The invention relates to a large-scale blast furnace stemming used bond and the blast furnace stemming thereof, and the components of the bond (the weight proportion) is: coal tar: 10 to 60, phenolic resin: 5 to 20 and asphalt: 20 to 80. The asphalt is high temperature powder asphalt or high polymerization asphalt, and the softening point is no less than 100 DEG C; the bond is made by stirring under 50 DEG C to 70 DEG C. The blast furnace stemming with the bond is the large-scale blast furnace stemming of the invention. The large-scale blast furnace stemming used bond has the advantages that: (1) the bond which is fast in sintering speed can adjust structure defects and improve the rate of residual carbon at the same time, and the stemming slag resistance, the sintering strength and the opening performance can be improved obviously; (2) when in use, the bond is superior to tar in the aspect of environmental and healthy, and the product stemming is environment-friendly and has less odor; (3) the stemming prepared by the bond is lower than resin-bond stemming in price; (4) the plasticity of the stemming prepared by the bond is better than that of the resin-bond stemming and is equivalent to that of tar-bond stemming.
Description
Technical field
The present invention relates to a kind of large blast furnace stemming wedding agent and large blast furnace stemming thereof.
Background technology
Blast furnace mud has water, tar, resin and multiple wedding agent to unite the wedding agent of use with wedding agent.The water system blast furnace mud can only be used for small blast furnace, most tar and the resinoid bonds of adopting of large blast furnace stemming, and tar is widely adopted in conjunction with the stemming excellent property, but the shortcoming of following several respects is arranged: the harmful fugitive constituent of part is arranged in (1) production and the use; (2) the volatile gases evaporation rate is slow, causes tar articulated system sintering velocity slow.It is suitable that existing resin-bonded stemming and this wedding agent combine the stemming performance, but have following shortcoming: (1) poor plasticity, and it is poor to reach workability; (2) shortcoming on the high side.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing large blast furnace stemming with wedding agent, the invention provides a kind of blast furnace mud wedding agent, the stemming sintering velocity that adds this wedding agent is fast, and plasticity-is better than the resin-bonded stemming; Provide a kind of sintering velocity fast simultaneously, plasticity-is better than the blast furnace mud of resin-bonded stemming.
The performance of composition decision wedding agent, this large blast furnace stemming with the composition (weight proportion) of wedding agent is:
Coal tar 10-60;
Resol 5-20;
Pitch 20-80
Pitch is that high temperature powdered asphalt or high polymerization shape are gone through green grass or young crops, and softening temperature is not less than 100 ℃, and general softening temperature is 125 ℃-140 ℃.
Stir the wedding agent that modulation forms at 50 ℃-70 ℃.
The optimal components of this wedding agent (weight proportion) is:
Coal tar 35 resol 12.5 pitches 50.
The composition (weight proportion) that contains the large blast furnace stemming of this wedding agent is:
Fused corundom 40～60 silicon carbide 15～20 clays 5～10
Coke powder 5～8 sericites 5～10 wedding agent 10-18.
This large blast furnace stemming has following advantage with wedding agent: (1) adopts the stemming sintering velocity of this wedding agent fast, simultaneously can regulate tissue defects, improve the carbon residue rate, stemming slag resistance, sintering strength, opening performance all are significantly increased, be embodied in: tapped a blast furnace time lengthening 30-60 minute when adopting the stemming of this wedding agent to use on blast furnace, opening time shortens 5-8 minute; (2) with the stemming of this wedding agent preparation environmental protection and healthy aspect be better than tar, be in particular in that finished product stemming environmental protection smell is little; (3) stemming with this wedding agent is lower than resin-bonded stemming price; (4) plasticity-with the stemming of this wedding agent is better than the resin-bonded stemming, and to combine stemming suitable with tar.
