The electroslag remelting of the die steel belongs to the secondary die steel refining method. The consumable electrode is its raw material, and the consumable electrode can be obtained by other die steel smelting methods, such as electric arc furnace, induction furnace, vacuum induction furnace and vacuum consumable furnace. And other preparations.
The purpose of the electroslag remelting of the die steel is to further refine the steel and alloy and improve the crystal structure of the steel ingot on the basis of the preliminary refining, thereby obtaining high quality metal products. So what are the characteristics of die steel electroslag remelting?
1 The melting, casting and solidification of metals are achieved in a purer environment, reducing the contamination of molten steel.
2 has a good metallurgical reaction thermodynamic and dynamic conditions, die steel electroslag remelting process in the slag pool temperature is usually above 1750 °C, the electrode from the bottom of the electrode to the molten metal in the center of the molten pool temperature up to about 1900 °C, liquid steel The superheat can reach about 450°C, and the high temperature molten pool promotes the metallurgical physics chemical reaction. Zhongshan Fahrenheit Special Steel Co., Ltd. expressed that good dynamic conditions are reflected in the steel slag can awaken full contact during the electroslag remelting process of the mold steel. At the same time, due to the stirring effect of the electromagnetic force, the contact surface of the steel slag is constantly updated, the metallurgical reaction is strengthened, and the Removal of harmful impurities and non-metallic inclusions.
3 The top-down sequential solidification conditions ensure that the crystal structure of the remelted metal ingot is even and dense.
4 The thin and uniform slag shell formed between the water-cooled crystallizer and the steel ingot ensures the smooth surface of the remelted steel ingot of the mold steel.
The above is the introduction of the features of the electroslag remelting of die steel in Zhongshan Fushun Special Steel Co., Ltd. If there is any doubt, please call for advice.
