Abstract
The invention relates to quick lime powder surface modified of needed modifying material to upgrade product grade in steel smelting and producing technology. There needs flock continuous dusting in process of steel secondary smelting in order to produce high quality steel, but powder without source modified processing is easy to moisture absorption, cementation, gathering, these results in that powder transmission, jet apparatus are blocked and influence producing seriously. The aim of the invention is researching a quick lime powder structure modified to resolve the problem effectively, it is mainly made up of hard acid acetone, silicon, hydrous carbinol, additive hard acid is put into reaction cauldron (1) and is dissolved with acetone, after it is liquefied it and the anhydrous carbinol are put into reaction cauldron (2) which has a high-speed blender and are mixed fully.
Description
Technical field: the present invention relates in the smelting iron and steel production technology, be the required material modified lime powder surface modifier of the grade of improving the quality of products.
Background technology: at present, molten steel in smelting iron and steel, in the secondary refining production process of molten iron, need a large amount of continual dusting, especially production high-quality steel, special steel material, during the continuous casting and rolling of special-purpose thin plate is produced, the quality of blowing process depends primarily on the surperficial physicochemical property of powder, and the powder of long time without surface modification, because very easily the moisture absorption causes the problem of the sticking associated holding of particle group, causes powder conveying, blowing device sun plug and stream of pulses, have a strong impact on enterprise's ordinary production and the quantity and the quality that influence product, current, the only West Europe ESM company simple monopoly supply of material of the whole world seriously restricts developing of China's Iron And Steel Industry.
Summary of the invention: purpose of the present invention is invented a kind of particle that do not make and is glued associated holding group for overcoming above-mentioned weak point, thereby improves the quality of products lime powder surface modifier with output.
The present invention is achieved in that compositions such as its employing stearic acid, acetone, anhydrous methanol, additive, silicone oil constitute.Its production technique is after pressing composition prescription metering, mixes, packs after the stirring, dissolution filter and form.
Embodiment;
It is as follows that lime powder surface modifier of the present invention is specifically implemented compound method:
A. fill a prescription: (precentagewise)
Prescription one: stearic acid 60%, anhydrous methanol 38%, dispersion agent 12%.
Prescription two: stearic acid 60%, acetone 30%, anhydrous methanol 10%, additive 10%.
Prescription three: stearic acid 60%, acetone 25%, silicone oil 20%, additive 5%.
B. technology: above-mentioned prescription precentagewise is assorted, stearic acid is injected reactor (1) again, use acetone solution, the back of waiting to liquefy inserts with compositions such as anhydrous methanol, additives that thorough mixing evenly gets final product in the band homogenizer reactor (2).
In sum, lime powder surface modifier of the present invention, technology maturation, production cost is low, and result of use is good.
Claims (1)
1, a kind of living stone flour surface modification agent, its feature specific implementation method is as follows;
A. fill a prescription: (precentagewise)
Prescription one: stearic acid 60% anhydrous methanol 38% dispersion agent 12%;
Prescription two: stearic acid 60% acetone 30% anhydrous methanol 10% additive 10%;
Prescription three: stearic acid 60% acetone 25% silicone oil 20% additive 5%;
B. technology: above-mentioned prescription precentagewise is assorted, stearic acid is injected reactor (1) again and use acetone solution, the back of waiting to liquefy inserts with compositions such as anhydrous methanol, additives that thorough mixing evenly gets final product in the band homogenizer reactor (2).
