| titleOfInvention | A kind of pan steel smelting technique |
| abstract | The present invention relates to a kind of pan steel smelting technique, the technical process includes high-quality iron ore and Rare Earth Mine and reducing agent 1) are ground into the powder that particle diameter is less than or equal to 300 mesh respectively, then proportionally mix, add water the cooled agglomerated pellet in the environment of temperature is 0 30 DEG C；2) again by pelletizing and smokeless coal cinder of the lumpiness for 30 80 ㎜, layering is alternately added in the refining equipment with multiple rows of air outlet, refining equipment is blown into hot blast by hot-air mouth, and hot blast temperature is controlled more than 1100 DEG C, and by solid direct-reduction and gas indirect reduction, smelting process obtains molten iron simultaneously；3) molten iron is molded into ingot；4) electric furnace refining is traditionally carried out, pan steel molten steel is obtained.The refining process of the present invention carries out more than 500 experiments, process stabilizing.The pan of refining with heavy metal elements such as " chromium, nickel, cadmium, lead, arsenic " is not both contained in steel, again have with stainless steel identical decay resistance, while having the steel grade of white metal gloss. |
