How to prevent ladle refractory material sticky slag

With the following proper methods, we could prevents the ladle refractory material sticky slag from steel making.
It will guarantee the better quality of steel.
1. Increasing the hot turnover of ladle and decreasing the quantity and time of turnover of ladle.
2. Do better cleaning work of ladle, clean the ladle timely and fully, especially for the ladle month part.
3. Repair the damaged parts of the ladle lining timely, to prevent the molten steel and slag from entering into the lining.
4. Pour the slag out timely after work, shorten the time from pouring to turning over of the ladle.

6. Control the quantity of ladle, shorten the time of ladle keep for waiting, and do preheating before put the ladle into work.
7. On refractory material, better the masonry quality, use the suitale size of fire bricks and improve the capacity of thermal shock resistance.
8. With suitable ladel covering agent, the use of it will keep the ladle insulated and with less ladle slag.
9. Choose the same grade of mortar to refractories brick, such as with clay mortar for clay firebrick and magnesia mortar for magnesia firebricks.
