Изобретение касаетс способа травлени стали и может быть использовано при острешш концов прутков и штанг перед волочением и калибровкой.The invention relates to a method of pickling steel and can be used for extruding the ends of rods and rods before drawing and calibration.
Известен способ травлени стальных заготовок в расплаве металла, например железа.The known method of pickling steel billets in the molten metal, such as iron.
Предлагаемый способ отличаетс тем, что обработку производ т в расплаве алкн мини при. 85О- 9ОО С.The proposed method is characterized in that the treatment is performed in the melt of alkn mini at. 85O-9OO S.
При использовании расплава алюмини в качестве растворител железа повышаетс скорость растворени железа. Установ , лено, что при температуре жидкого алюмини пор дка BOO-GOO-C интенсивность растворени стальных заготовок составл- - ет 1,5 мм R течение 20 мин.When using molten aluminum as an iron solvent, the rate of dissolution of iron increases. It has been established that, at a liquid aluminum temperature of the order of BOO-GOO-C, the dissolution rate of the steel billet is 1.5 mm R for 20 minutes.
При взаимодействии расплавленного алюмини с металлом заготовки образуетс сплав железа с алюминием, имеющий больший удельный вес, чем алюминий, и осаждающийс на дно- ванны.When molten aluminum interacts with the billet metal, an iron-aluminum alloy is formed that has a larger specific gravity than aluminum and precipitates on the bottom.
Известные методы утилизации этого спла . BQf вл ющегос отличным сырьем дл алюминиевого производства, позвол ют избежать безвозвратных потерь алюмини .Known methods of disposal of this spla. BQf, an excellent raw material for aluminum production, avoids irretrievable loss of aluminum.
Предмет изобретени Subject invention
Способ травлени стали в расплаве металла , :отличающийс тем, что, с целью острени концов прутков и штанг перед волочением и калибровкой, обработку прювод т в расплаве алюмини при 850- 90О°С.The method of steel etching in the molten metal: characterized in that, in order to sharp the ends of the rods and rods before drawing and calibration, the processing is done in the molten aluminum at 850-90 ° C.
