Prospects for Processing of Ferrous Metallurgical Waste Based on Arcelormittal Temirtau Experience

The article deals with method of purifying the exhaust gases in an automobile muffler or other transport equipment using electrical pulses. Electrical pulses are formed between the two ring electrodes (anode and cathode) installed in series along the gas flow. The physical picture of the process is described. A mathematical model has been developed and studied. A deterministic relationship has been established between the engine volume, the number of the crankshaft revolutions, the electric field strength and the charge strength and dynamic viscosity of the gas. Experimental studies have been carried out. The goal of the experiment was to confirm the hypothesis of impact ionization of exhaust gases. The effectiveness of electrical pulse purification has been proven.

“…A whole area is dealing with the gas purification including exhaust electrostatic precipitators using an electric field and electrical breakdown of gas: a corona discharge [8].…”

“…At the same time, one of the most material-intensive, financial and energy-consuming operations in the road construction, is the production of building materials and its transportation to the place of road building. This fact determines the relevance of the development of new cheaper materials for road building [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

The article proposes a technological line for recycling the blast-furnace slag. This line makes it possible to obtain the crushed stone for road building, which has high water and frost resistance. The design of replaceable working equipment of a single-bucket excavator, with replaceable working tools for loosening frozen slag in dumps and preparing it for use in road building, is proposed. The results of testing the manufactured replacement working equipment are presented. The results of mathematical processing of experimental data using the approximation method are presented, as well.

“…If it is impossible to clean the tubes on one side, the second radiator tank is soldered and cleaned on the other side. The mechanical cleaning method is characterized by high labor intensity and the associated high costs of time and money for the cleaning process [14]. The radiator tubes are often damaged, and it comes into disrepair.…”

The article deals with the existing methods of cleaning vehicle radiators from sedimentary scale. A method of cleaning radiator tubes by ultrasonic radiation is proposed. An experimental bench has been developed for studying ultrasonic cleaning processes. Based on the results of the experiment, dependences have been obtained that determine the efficiency of the process depending on the mass of scale removed and the liquid outflow rate from the tubes. There are proposed the purification degree coefficients. The hypothesis about the possibility of cleaning radiators with ultrasonic vibrations has been confirmed.
