Description

Technical field

[0001] The invention relates to the technical field of preparation of pre-melted slag for electroslag remelting, in particular to a method for preparing low-silicon pre-melted slag for electroslag remelting. Background technique

[0002] Pre-melted slag is an important guarantee for electroslag remelting to produce high-quality special steel and high-end alloy materials. Compared with ordinary mixed slag materials for electroslag remelting, pre-melted slag has obvious characteristics such as uniform composition, low moisture absorption, and low melting point. Therefore, it can greatly reduce the difficulty of arcing slag and shorten slagging during use. Time, avoid the occurrence of slag collapse and other phenomena, thereby ensuring the safety and efficiency of the electroslag remelting process. At the same time, pre-melted slag can also effectively improve the quality of the bottom, surface and interior of the electroslag ingot, can effectively reduce the hydro...
