Description
Способ повышени газопроницаемости агломерационной шихты из тонкоизмельченных материалов путем добавки извести известен. Известны опыты по агломерации железованадиевого материала, при которых в состав шихты, кроме извести, вводили железную руДУ- Дл создани в зоне спекани л идких фазA method for increasing the gas permeability of an agglomeration mixture of finely divided materials by adding lime is known. Experiments on the agglomeration of iron-and-vanadium material are known, in which, in addition to lime, iron ore was introduced into the composition of the charge. To create in the sintering zone
однокальциевого феррита предлагаетс в шихту вводить порошковую смесь извести и железосодержащего материала, вз тых в стехиометрическом соотношении, отвечающем формуле однокальциевого феррита. Порошковую смесь ввод т в количестве Юо/о веса шихты.moncalcium ferrite is proposed in the mixture to introduce a powder mixture of lime and iron-containing material, taken in a stoichiometric ratio, corresponding to the formula of monocalcium ferrite. The powder mixture is introduced in an amount of 10 O / o weight of the charge.
Дл упрочнени агломерата и повышени скорости его спекани приготавливают смесь, состо щую из тонкоизмельченной извести и порошковатого железосодержашего материала . Эти компоненты берут в стехиометрическом соотношении, отвечающем формуле однокальциевого феррита (СаО-РеаОз).To strengthen the agglomerate and increase its sintering speed, a mixture consisting of finely divided lime and powdered iron-containing material is prepared. These components are taken in a stoichiometric ratio corresponding to the formula of single-calcium ferrite (CaO-ReaOz).
Тшательно перемешанна смесь равномерно распредел етс по всему объему шихты и способствует образованию в зоне спекани жидкой фазы однокальциевого феррита, обладающей после кристаллизации высокой прочностью.The thoroughly mixed mixture is evenly distributed throughout the entire volume of the mixture and contributes to the formation in the sintering zone of the liquid phase of single-calcium ferrite, which after crystallization has high strength.
Жидка фаза однокальциевого феррита хорошо смачивает и пропитывает агломерационную шихту, в результате чего образуетс прочный агломерат.The liquid phase of monocalcium ferrite well wets and impregnates the sinter blend, resulting in a strong agglomerate.
Предмет изобретени Subject invention
Способ упрочнени агломерата и повышени скорости его спекани , отличающийс тем, что, с целью создани в зоне спекани й идких фаз однокальциевого феррита, в шихту , например, в количестве Юо/о от веса, ввод т порошковатую смесь извести и железосодержащего материала, вз тых в стехиометрическом соотношении, отвечающем формуле однокальцпевого феррита.The method of strengthening the agglomerate and increasing its sintering speed, characterized in that, in order to create in the sintering zone of the icy phases of monocalcium ferrite, a powder mixture of lime and iron-containing material, taken in the stoichiometric ratio, corresponding to the formula of single-calcium ferrite.
