Изложен наименее изученный раздел в металлургии, касающийся механики движения шихты, на основе результатов которого разработаны расчеты высоты и очертаний профиля доменных печей применительно к условиям плавки титаномагнетитов и АСУ потоком материалов. Впервые разработано устройство для непрерывной регистрации давления потока столба шихты в зависимости от сил трения в верхней половине шахты доменной печи и алгоритм подсчета составляющих баланса сил, обеспечивающих движение материалов.
Для повышения интенсивности доменной ванадиевой плавки усовершенствовали профили типовых доменных печей полезным объемом 1242–1719 м , а на Качканарском ГОКе испытали технологии обжига нескольких видов офлюсованных и неофлюсованных окатышей. Начиная с июня 1993 г. перешли на плавку малоразрушающихся неофлюсованных окатышей и агломерата повышенной основности. Внедрение комплекса мероприятий в 1983–1988 гг. позволило в сравнении с 1982 г. увеличить выплавку ванадиевого чугуна на 25,1%, уменьшить удельный расход кокса на 4,4% и снизить содержание серы в чугуне с 0,028 до 0,022%.
Впервые в РФ после передачи металлургии частному капиталу за короткий срок 2004–2008 гг. на ОАО «НТМК» построен комплекс, состоящий из 2 доменных печей нового поколения. Достигнуты технологические показатели плавки хорошо подготовленных титаномагнетитовых агломерата и окатышей Качканарского ГОКа на уровне передовых предприятий за рубежом при использовании магнетитового сырья. Основной причиной снижения кампании доменных печей до 4–5,5 лет следует считать работу на пониженных дутьевых параметрах, при которых в зону потока материалов вошли холодильники заплечиков. Для повышения стойкости холодильников и образования защитного слоя гарнисажа необходимо вести доменный процесс с высокой степенью уравновешивания шихты газовым потоком, обеспечивая значение критерия активного веса потока материалов в диапазоне 0,500–0,600. Для достижения этой цели предложено подключить к основной турбовоздуходувке дополнительный компрессор высокого давления и изменить конструкцию заплечиков при подготовке к следующей кампании.
Разработана и внедрена технология доменной плавки передельного чугуна с использованием до 30% неофлюсованных окатышей на металлургических комбинатах Урала и Сибири, что служит основанием для дальнейшего развития Качканарского ГОКа и разработки других месторождений титаномагнетитов.
Предназначено для научных работников горно-металлургической промышленности, специалистов-технологов и проектных институтов; будет полезно преподавателям, студентам и аспирантам металлургических специальностей.

–Books and Movie Reviews, Roberto Mattos (regarding Rise of the Dragons)

A bundle of the first two books in Morgan Rice’s new #1 Bestselling epic fantasy series OF CROWNS AND GLORY (SLAVE, WARRIOR, QUEEN and ROGUE, PRISONER, PRINCESS). Here are two bestselling novels, all in one convenient file, which offer a great introduction to the OF CROWNS AND GLORY series.

In SLAVE, WARRIOR, QUEEN,17 year old Ceres, a beautiful, poor girl in the Empire city of Delos, lives the harsh and unforgiving life of a commoner. By day she delivers her father’s forged weapons to the palace training grounds, and by night she secretly trains with them, yearning to be a warrior in a land where girls are forbidden to fight. With her pending sale to slavehood, she is desperate. 18 year old Prince Thanos despises everything his royal family stands for. He abhors their harsh treatment of the masses, especially the brutal competition—The Killings—that lies at the heart of the city. He yearns to break free from the restraints of his upbringing, yet he, a fine warrior, sees no way out.

In ROGUE, PRISONER, PRINCESS . 17 year old Ceres, finds herself forced, by royal decree, to fight in the Stade, the brutal arena where warriors from all corners of the world come to kill each other. Pitted against ferocious opponents, her chances of survival are slim. Her only chance lies in drawing on her innermost powers, and making the transition, once and for all, from slave to warrior. 18 year old Prince Thanos wakes on the isle of Haylon to discover he has been stabbed in the back by his own people, left for dead on the blood-soaked beach. Captured by the rebels, he must crawl his way back to life, find who tried to assassinate him, and seek his revenge. Ceres and Thanos, a world apart, have not lost their love for each other; yet the Empire court teems with lies, betrayal and duplicity, and as jealous royals weave intricate lies, they each, in a tragic misunderstanding, are led to believe the other is dead. The choices they make will determine each other’s fate.

And in the backseat of Caroline's car are two children who were orphaned in a single chilling moment–five-year-old Addie and six-year-old Flick. She's now their legal guardian—a role she’s not sure she’s ready for. But Oysterville has changed. Her siblings have their own complicated lives and her aging parents are hoping to pass on their thriving restaurant to the next generation. And there's Will Jensen, a decorated Navy SEAL who's also returned home after being wounded overseas. Caroline is drawn back to her favorite place: the sewing shop owned by Mrs. Lindy Bloom, the woman who inspired her and taught her to sew. There she discovers that even in an idyllic beach town, there are women living with the darkest of secrets – and one of those women is her. Thus begins the Oysterville Sewing Circle, where Caroline finds the courage to stand and fight for everything—and everyone—she loves.
