1 and the ordinary electric arc furnace smelting joint, speeding up the production cycle, improve the recovery rate of alloys.
2 with the ladle refining furnace technology, harmful elements in the steel liquid and harmful gas is reduced to a lower level, so that the steel is not easy to form the non-metallic inclusions have serious damage to the casting material, thereby increasing the casting temperature performance and casting on the use of environmental adaptability.
Effect of argon stirring 3 to accelerate the chemical reaction between the steel / slag, desulphurization, deoxidation of liquid steel is beneficial to promote the, metal debris floating and removal of the liquid steel, improving the uniformity of liquid steel temperature and composition.
4 simple equipment, low investment.
Use ladle still need to solve the problem of refining furnace
1 molten steel temperature drop. Because the furnace and electric arc furnace connected operation ladle refining, in the ordinary electric arc furnace steel liquid oxidation is completed to refining furnace tapping, liquid steel temperature decreased, the smaller, the more the temperature drops. This refining furnace for heating operation, will slightly increase power consumption.
The 2 mode will increase the gas content of liquid steel, steel liquid refining outside the furnace, the content of all kinds of gas in the liquid steel can reduce. But in the liquid steel rental process, easy to make steel liquid suction, resulting in steel liquid gas content slightly increased, existing solutions. |
