Rourkela Steel Plant (RSP), the first integrated steel plant in the public sector in India, was set up with German collaboration with an installed capacity of 1 million tonnes. Its 1st Blast Furnace 'Parvati' was lighted up by Dr. Rajendra Prasad, the then President of India on 3rd February 1959. Subsequently, its capacity was enhanced to 2 ...
The ladle sliding nozzle is an important system to control the flow of molten steel in the ladle. If the system has a steel-piercing accident during use, it will lead to vicious production accidents such as the breakage of the casting machine and the burning of the continuous casting machine equipment, which restricts the stable and smooth …
Where Q m is a flow rate, kg/s. D is the diameter of a nozzle, 0.075 m for the casting.ρ l is the density of liquid steel, 7000 kg/m 3 for this case. α is a constant, 1 for the turbulent flow studied.g is the acceleration of gravity.h …
2458. The ladle was primarily used as a transfer vessel to transport liquid steel from the converter steelmaking area to the caster. But in present times due to stringent quality demands it serves more as a process vessel where functions like temperature control, deoxidation, carburizing, ferroalloys addition and inclusion floatation …
Continuous casting (CC) is a process of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine. It is the predominant process route in a modern …
The steel plant is comprised of every section from raw material processing, arc furnace, ladle furnace, casting machine and more. ... The ladle containing qualified liquid steel is hoisted to a ladle rotator of continuous casting machine and then it taps from the base of the receiving ladle to tundish, after that, it drops down into ...
The operation of the hot metal ladle in a steel plant using the one-ladle technology on the ironmaking and steelmaking interface is mainly employed at the stage of hot metal pre-treatment and converter process. Fig. 1 shows the operation process of the hot metal ladle in the steel plant. After the heavy ladle enters the steel plant, it is ...
The use of online ladles can be reduced by one in the "four furnaces to three machines" production mode, and by two in the "four furnaces to four machines" production mode, thus making a significant contribution to the reduction of the number of online ladles in the steel plant. 4.2.2 Analysis of ladle temperature drop
