Abstract
The invention relates to a manufacturing process for electrically-fused aluminium chromium zirconium. The manufacturing process comprises the following steps: 1), preparing 30-40 parts of industrial aluminium oxide, 34-45 parts of chromium oxide green and 20-30 parts of zircon sand in parts by weight; 2), sufficiently mixing the mixed materials obtained in the step 1, pressing the mixed materials to be balls to prepare for smelting; 3), electrifying a three-phase electric arc furnace, and adding the materials to the furnace by uniformly dividing the input per hour in the step 2 into three times; 4), blowing down the furnace and cooling to form fused rolls after the furnace is filled with materials and the materials are fused; 5), crushing the fused rolls, removing iron ingredients by a magnetic separator, and finally packaging and storing the fused rolls. Through the manufacturing process, the refractory material is more suitable for severe conditions of a garbage incinerator, and service life of lining materials can be prolonged.
Description
Technical field
The present invention relates to a kind of manufacture craft of electric smelting aluminium chromium zirconium, be mainly used in the special refractories of incinerator, liner and chemical industry.
Background technology
Incinerator, liner and chemical industry high-temperature refractory, mostly taking high alumina refractories as main, this material property is more stable, is comparison purposes series product widely in refractories industry.This material is generally applied in fields such as metallurgy, building materials, chemical industry, the shortcoming of this series material mainly contain several aspect, because the general void content of this material is larger, generally in 3-5% scope, therefore erosion resistance is poor, this toughness of material is poor simultaneously, easily peels off, so be all generally same other materials fit applications during with this material in pyroprocess, make aluminium carbon goods as being combined with carbon, be combined into aluminium zirconium product etc. with zirconium.The gas that Refuse Incineration Process produces, liquid, strong to the aggressiveness of furnace lining material, general aluminum fire resistant materials is difficult to adapt to its mal-condition in application, and the inner lining material life-span is short.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of manufacture craft of electric smelting aluminium chromium zirconium, and this manufacture craft makes refractory materials be more suitable for incinerator mal-condition, can make inner lining material increase the service life.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of manufacture craft of electric smelting aluminium chromium zirconium, comprises the following steps:
1) according to ratio of weight and number, commercial alumina 30-40 part, chromoxide green 35-45 part, zircon sand 20-30 part are prepared burden;
2), after the compound of step 1 is fully mixed, compacting balling-up prepares to smelt;
3) after three-phawse arc furnace energising, the input amount per hour of the raw material in step 2 is evenly divided in three input stoves in per hour;
4) drop into after full stove, after material melting, the molten stone roller of the cooling rear formation of blowing out;
5) will melt after stone roller fragmentation, get rid of with irony composition through magnetic separator, last packaging final prod warehouse-in.
The manufacture craft of this electric smelting aluminium chromium zirconium adopts above-mentioned steps, above-mentioned starting material proportionally can be carried out to melting, thereby produce electric smelting aluminium chromium zirconium xln, this xln uses in refractory materials, be more suitable for incinerator mal-condition, can make inner lining material increase the service life.
Embodiment
Embodiment mono-
