Ladle Nozzle Filling Sand

Ladle Nozzle Filling Sand Introduction:

Ladle nozzle filling sand contains metal mixture whose weight is heavier and melting point is lower than molten steel. We put it into ladle nozzle before tapping, using it to protect the molten steel inside ladle nozzle from being solidified, to achieve the purpose of automatic casting.

Ladle filling compound is a kind of bulk refractory material filled in the ladle seat brick and the upper nozzle. It is divided into various series of products such as chromium, zirconium and silicon. According to the different conditions of each steel factory, select suitable products for production. It has good fluidity, chemical stability, moderate particle size, good compaction and high temperature performance, and its quality greatly restricts the automatic pouring rate of the ladle.

Ladle Nozzle Filling Sand Advantages:

Ladle nozzle filling sand is a kind of ideal ladle slid nozzle filler which is successfully developed by our company in recent years, automatic casting success rate of which can reach above 95 percent. There is no metallic inclusion in ingot surface. Ladle nozzle filling sand are used in steel tapping hole of large eccentric furnace bottom.  Ladle nozzle filling sand developed by our company is adapt to the need of increasing gradually in large-scale furnace in recent years.

1.Ladle filler sands  are used in steel tapping hole of large EAF bottom tap hole.

2.Ladle nozzle filling sand developed by our company is adapt to the need of increasing gradually in large-scale furnace in recent years.

3. It is  an ideal product to replace imported products.

4.The steel outflow from eccentric furnace, put electric fillers in at EBT platform, when the steel stuffing can outflow from steel pore while steel water flow into ladle. 

5. Automatic free-opening rate can reach over 95%.

Ladle Nozzle Filling Sand Function:
Ensure automatic ladle pouring, reduce molten steel open pouring time, prevent secondary oxidation of molten steel during pouring, improve billet quality, speed up pouring rhythm, increase and decrease the number of continuous casting furnaces, and reduce the labor of continuous casting machine ladle pouring Strength, put an end to accidents such as scalding ladle pouring due to non-self-burning oxygen.

Advantages of Ladle silicon filling compound:

1. It has the advantages of good fluidity, high specific gravity and fast speed.

2. Strong ability to resist molten steel corrosion.

3. High refractoriness, easy to produce mild sintering with molten steel, no clogging
