Life

Grum-Grschimailo's father, Jefim Grigorjewitsch Grum-Grschimailo, was an economist and expert in beet sugar and tobacco production . The mother Margarita Mikhailovna born Kornilovich was the daughter of the historian Mikhail Ossipowitsch Bes-Kornilowitsch and niece of the Decembrist Alexander Ossipowitsch Kornilowitsch . Grum-Grschimailo attended the 3rd St. Petersburg Military High School from 1873-1880 and then studied at the St. Petersburg Mining Institute with a degree in 1885. He then worked in metallurgical plants in Alapayevsk , Nizhny Tagil , Nizhnyaya Salda with Konstantin Pavlovich Polenow and Verkhnyaya Salda .

In 1907 Grum-Grschimailo became adjunct and in 1911 full professor at the St. Petersburg Polytechnic Institute . He demonstrated the economic viability of a Russian Bessemer procedure and developed the theoretical basis. Using the laws of physical chemistry , he explained the processes in the Bessemer process and also in the Siemens-Martin furnace . He developed a furnace theory, describing the movement of furnace gases using the laws of fluid mechanics . He examined the material properties of refractory materials with at least 93% silicon dioxide . Another focus of work was calibration during rolling . One project was dedicated to the furnaces for heating ingots for forging and slabs for rolling.

After the October Revolution and the civil war that followed , Grum-Grschimailo lived with his family in the Urals . In 1919 he was a professor at the Tomsk Polytechnic Institute . In 1920 he became a professor at the Ural University in Yekaterinburg and headed the chair for steel and heat treatment furnaces . In 1924 he defended the geologist Modest Onissimowitsch Kler , who was accused of espionage for France . Because of the incipient agitation, Grum-Grschimailo had to leave Yekaterinburg and went to Moscow . He now taught at the Moscow Mining Academy and founded an office for metallurgy and heat engineering constructions , which in 1930 became the State Steel Project Institute.

Grum-Grschimailos brother was the geographer Grigori Eefimowitsch Grum-Grschimailo .
