Abstract
The present invention provides a kind of powder material method for processing forming for the production of inorfil cotton.The method, with addition of a small amount of inorganic gel powder and water, by working processes such as quantitative ingredient, uniform mixing, hydrostatic profile and natural curings, is obtained the block feed stock for blast furnace that can be directly added into high temperature melting furnace with powdery industrial solid castoff as primary raw material.The present invention relates to the method for processing forming that powder material in inorfil cotton production technology enters stokehold, the preprocessing shaping that flyash class industrial solid castoff prepares inorfil cotton raw materials for production is particularly well-suited to.Block feed stock for blast furnace prepared by the present invention has intensity high, and heat resistanceheat resistant fragmentation ability is strong, and material composition is uniform, allocates coke powder fuel into, can save block coke, advantageously reduces production cost, the advantages of improve product quality, is suitable to industrialized production and application.
Description
Technical field
The present invention relates to the raw material preprocessing method in the production of inorfil cotton, and in particular to one kind is used for inorfil cotton
The powder material processing molding method of production.
Background technology
In the existing extensive production technology for preparing inorfil cotton, fired as original with various massive ores and block coke
Material is directly added into soaring smelting furnace, and to blasting air in furnace cupola, and the oxygen in air and coke react releasing heat, make
Ore is melted at high temperature, is made high temperature melting slurry.There is following defect in such traditional handicraft：1. raw material composition distribution
Inequality, causes product quality to fluctuate larger, and particularly lump material is caused between different ores, composition is poor between ore and coke
It is different larger, it is difficult to uniform mixing；2. block coke all is needed to use, causes fuel cost to increase；3. powder material cannot be straight
Connecing addition smelting furnace can just enter stove, it is necessary to be prepared into the lump material with good cold strength and calorific intensity performance.
The content of the invention
A kind of problem it is an object of the invention to be directed to traditional handicraft presence, there is provided powder for the production of inorfil cotton
The method of body Raw material processing shaping, the method can realize that vast scale, with addition of industrial powder solid waste, reduces raw materials for production cost, enter
Stove raw material composition is evenly distributed, and improves production stability and properties of product.
A kind of powder material method for processing forming for the production of inorfil cotton that the present invention is provided, including following step
Suddenly：As mass fraction, first by flyash 45-55, slag 30-40 mixing stirs；Then to adding water in mixed material
Mud 8-10, adding appropriate water moistens material, stirs；It is eventually adding coke powder 6-12, stirring mixing；Thing after mixing
Material is pressed, and briquetting pressure is 9-30 MPas, and the dwell time is 3-5 minutes；Type block is carried out into natural curing, maintenance temperature
It is normal temperature to spend, and maintenance humidity is more than 98%, and curing time is 28 days.
The product of present invention processing meets technical requirements (alundum (Al2O3) and the silica of inorfil cotton raw materials for production
Content sum is 1.2~2 than the ratio of upper calcium oxide and content of magnesia sum, and coordinate calcium oxide content in raw material be 25~
45%, alundum (Al2O3) content be 8~18%, dioxide-containing silica be 38~52%), be used directly for the block of high melt
Shape feed stock for blast furnace.
Compared with prior art, the present invention matches somebody with somebody with flyash, industrial pulverized coke and other powder industry solid wastes as primary raw material
Plus a small amount of inorganic gel agent, the lump material met into stove requirement is prepared into by cold pressing forming process.Raw material sources are extensive, valency
Lattice are cheap, advantageously reduce production cost (addition of coke powder can reduce the consumption of block coke during firing)；Process is cleaned
Environmental protection, process is simple, it is easy to industrial scale production application；Additionally, the powder material mixed-forming in proportion that the present invention is provided
Enter stove, be advantageously implemented the uniformity into stove material, so as to improve production stability and properties of product.
Specific embodiment
Embodiment 1:
A kind of method of the crude fuel processing and forming produced for inorfil cotton is provided according to the present invention, according to such as following table
Shown material rate formula：
Specific implementation process is：
First respectively with electronic balance according to 1#Number formula accurately weighs flyash 54g, steel-making slag powder 36g, cement 10g, water
18g；According to 2#Proportion speed weighs a certain amount of flyash 51.84g, steel-making slag powder 34.56g, cement 9.6g, coke powder 4g, water
18g；According to 3#Proportion speed weighs a certain amount of flyash 50.76g, steel-making slag powder 33.84g, cement 9.4g, coke powder 6g, water
18g；According to 4#Proportion speed weighs a certain amount of flyash 49.68g, steel-making slag powder 33.12g, cement 9.2g, coke powder 8g, water
18g；According to 5#Proportion speed weighs a certain amount of flyash 48.6g, steel-making slag powder 32.4g, cement 9g, coke powder 10g, water 18g；Press
According to 6#Proportion speed weighs a certain amount of flyash 47.52g, steel-making slag powder 31.68g, cement 8.8g, coke powder 12g, water 18g, completes
Material weighing.
Then respectively by above-mentioned 1#-6#Material in formula is added in the following order：First flyash, steel-making slag powder are placed in
3min is stirred in mortar mixer；Again to the Ni Heshui that added water in mixed material, continue to stir 10min, material is sufficiently mixed
It is even；Coke powder is added in most backward compound, and stirs 5min.Then take out mixed material, be put into steel die, static pressure into
Diameter 30mm, the cylindrical type block of height 12mm are pressed into type device.Hydrostatic profile device arrange parameter is：Pressure 700kgf
(about 9.7MPa), voltage stabling control 3min, temperature is room temperature, then compressing type block is put into plastic sealing bag, is supported naturally
Shield tests its cold conditions compression strength and hot compression strength after 28 days.
Cold conditions intensity test operating process is according to concrete test block intensity test standard, using universal test
Machine carries out intensity test；Calorific intensity test be that type block is directly placed into 800 DEG C of Muffle furnaces by room temperature, and according to 5 DEG C/
Furnace temperature is risen to 900 DEG C, 1000 DEG C, 1100 DEG C by min speed, and whether observation type block bursts respectively, then to the type block that does not burst again
Carry out intensity test.
Experimental result：
Raw material processing is molded according to step of the present invention, the cold conditions compression strength for measuring and hot compression strength value are such as
Shown in following table：
