Abstract
The present invention discloses a homogeneous slag blocking ball and a producing method thereof. The present invention is characterized in that the homogeneous slag blocking ball is composed of magnesia, iron ore, water glass adhesive and high-alumina cement. The producing method comprises the following steps: firstly, magnesia fire-resistance material and the iron ore of different specific weight are broken and crushed; then, the material is divided into various granularity by sieving; raw material of the magnesia, the iron ore and the high-alumina cement are put into a mixer, and the water glass adhesive is added to the mixer to be mixed with the raw material; after the raw material and the water glass adhesive are well mixed, the mixture is put into a mould of a slag blocking ball and is formed by vibration forming on a vibration table; after the mixture is formed, the mixture is put into a drying box to be dried by 5 h to 15 h, and natural cooling and mould releasing are carried out; finished products are put into a finished-product stock to be stored. The present invention has the characteristics of high production efficiency, low cost and good use effect. Compared with the existing production technique, the present invention has the advantages that the production efficiency is improved by more than 300 times; the product strength is improved by 50%; the cost is reduced by 40%.
Description
Technical field
The present invention relates to remove in the steelmaking process a kind of device and the material technology field that slag keeps molten steel purity, especially a kind of homogeneous skimming ball and preparation method thereof.
Background technology
At present, remove slag and keep in the operation of molten steel purity in steelmaking process, the slag retainer that includes iron core formula mechanical pressing is adopted in the production of this series products usually, and it need at first make the slag retainer head, make tail rod again, then slag retainer head and tail rod are assembled into slag retainer, this production method complexity of production has been wasted a large amount of steel again, intensity difference, yield poorly, the cost height does not fit into the requirement of STEELMAKING PRODUCTION.
Summary of the invention
The purpose of this invention is to provide a kind of output height, cost low, easily produce and vibratory compaction homogeneous skimming ball that pushing off the slag is effective and preparation method thereof.
Homogeneous skimming ball is characterized in that: it is made of by weight percentage following refractory materials:
Magnesia 70-80%;
Iron ore 10-17%;
Water glass caking agent 3-7%;
High-alumina cement 3-6%.
The production method of homogeneous skimming ball is characterized in that: at first the iron ore with magnesia refractory materials and different specific weight carries out fragmentation, pulverizing, sieves then material is divided into various different grain sizes; 70-80% magnesia, 10-17% iron ore, 3-6% high-alumina cement starting material are put into stirrer, and add the 3-7% water glass binder and mix mutually, binder dosage is the raw-material weight ratio, after mixing, mixture is put into the slag-blocking ball mould, the dry 5h-15h of loft drier is put in vibratory compaction on shaking table after the moulding, temperature is controlled at 180 ℃-250 ℃; After the drying, the naturally cooling demoulding, finished product is put into stockyard and is stored.
The present invention adopts aforementioned production method, has production efficiency height, cost is low, result of use is good characteristics, compares with existing production technology, enhances productivity more than 300 times, and product strength improves 50%, reduces cost about 40%.According to steel mill's production requirement, use the material of different specific weight, can regulate the proportion of slag-blocking ball, make it be applicable to different slag conditions, to reach ideal pushing off the slag effect.
Embodiment
Homogeneous skimming ball, it is made of by weight percentage following refractory materials:
Magnesia 70-80%;
Iron ore 10-17%;
Water glass caking agent 3-7%;
High-alumina cement 3-6%.
The step of manufacturing of homogeneous skimming ball is: at first the iron ore with magnesia refractory materials and different specific weight carries out fragmentation, pulverizing, sieve then material is divided into various different grain sizes, according to following proportioning:
Magnesia: 8-5mm accounts for 15% of weight of material per-cent
5-3mm accounts for 22% of weight of material per-cent
3-1mm accounts for 18% of weight of material per-cent
1-0mm accounts for 20% of weight of material per-cent
200 order granularities account for 20% of magnesia weight percent
Iron ore: 3-1mm accounts for 7% of weight of material per-cent
1-0mm accounts for 10% of weight of material per-cent
High-alumina cement: account for 4% of weight percent
200 orders account for 3% of high-alumina cement weight percent
Various starting material are put into stirrer and add the d=1.35 water glass binder and mix mutually, binder dosage is 4% of a raw-material weight ratio, after mixing, mixture is put into the slag-blocking ball particular manufacturing craft, vibratory compaction on shaking table, put into the dry 5h-15h of loft drier after the moulding, temperature is controlled at 180 ℃-250 ℃.After the drying, the naturally cooling demoulding, finished product is put into stockyard and is stored.Every piece of weight of homogeneous skimming ball is 40Kg.
Claims (2)
