How to Protect Refractories and Improve Service Life of Lalde The MgO in slag is eroded usually by furnace lining while making steel. In the process of smelting, the slag and refractory materials will get touched; MgO concentration in slag should almost reach saturation. There is a close relationship between the content of saturated MgO and CaO/SiO2. For slag with low alkalinity (CaO/SiO2<2.0), the higher the proportion of FeO is, the lower proportion of saturated MgO. When FeO content is low and saturated MgO content is high, the slag will erode more refractories. While for slag with high alkalinity (CaO/SiO2 >2.0), the saturated MgO content will not be seriously affected by the FeO content, what's more the slag will not erode much more refractories. Therefore, improve slag alkalinity can strongly protect refractories.
The service life of ladle is directly influenced by refining time, so it is important to improve steelmaking technology so that to shorten smelting time.
The service life of refractory ladle will be reduced by 3-5 heats once shut down, so to achieve efficient production, the key is shortening smelting cycle. On the premise of using advanced technology to guarantee the best steel quality and the lowest total consumption, shorten the smelting cycle to the minimum, improve equipment and shorten shut down time.

A ladle (Lay-dil)
That is a ladle.
A ladle with a wooden handle protects your hand from the heat of the food you are serving.
"ladle" is "louche" in French.
A ladle is a lever.
the function of ladle is to hold a liquid food
That is the proper spelling of the word ladle(spoon).
1. The ladle fell down while transporting molten metal. 2.Use the ladle to mix .
if u pour liquid metal in a ladle from furnace then cast in a mould,its called ladle tapping
You're going to need a ladle for that!
The buffet had a large ladle in each container of soup. The cook bent over to ladle more beans from the cooking pot.
yes the first ladle has been proved to be an accident
