SNREF Refractory Brick Magnesium Carbon Taphole Brick for Eaf
Product Description
Magnesia Carbon Bricks for the end of EAF tap hole are made from crystal,fused magnesia and high-purity graphite as raw materials;
Good oxidation resistance, high strength, good corrosion resistance, good integrity, easy to replace and long life.
I. Main Usage Instructions
It is used at the tapping hole of an electric furnace and serves as a crucial component of the molten steel outflow channel.
The details are as follows:
1. Guiding the Flow of Molten Steel - It provides a dedicated channel for molten steel to flow from the inside of the electric furnace to the ladle, ensuring that the molten steel can flow out of the electric furnace along a predetermined route and angle. Its precise shape and position design can effectively control the flow direction of the molten steel, ensuring a smooth and orderly tapping process, preventing the molten steel from splashing, and enabling the molten steel to be accurately poured into the ladle.
2. High - temperature Resistance and Protection- It can withstand the high - temperature environment during the tapping of the electric furnace. Its main components have the characteristic of high refractoriness (for example, it contains refractory materials such as magnesia - carbon, chrome - corundum, etc.). Under the scouring and erosion of high - temperature molten steel, it effectively protects the furnace body structure around the tapping hole of the electric furnace, preventing the furnace body from being damaged due to long - term exposure to high - temperature molten steel, thus extending the service life of the electric furnace.
3. Assisting in Slag - Steel Separation- During the tapping process, it plays a role in slag - steel separation to a certain extent. It can reduce the situation where slag flows into the ladle along with the molten steel. Since slag contains more impurities and oxides, excessive slag mixed into the molten steel will affect the quality of the molten steel and subsequent refining processes. Through a reasonable structural design and guiding effect during the tapping process, the tapping hole sleeve brick helps to reduce the slag mixed into the molten steel and optimize the quality of the molten steel.
4. Stabilizing the Tapping Process- It helps to stabilize the outflow speed of the molten steel. By factors such as its specific inner diameter, length, and internal structure, it controls the outflow speed of the molten steel, enabling the molten steel to flow out of the electric furnace at an appropriate flow rate. This is not only conducive to improving the tapping efficiency but also ensures that subsequent casting and other process steps can proceed smoothly, avoiding adverse effects on the entire steel - making process due to improper molten steel outflow speed.

FAQ
Below are some RFQ and answers about ladle and tundish flow control refractories:
Q: What are the requirements for refractories for ladle?
A: The requirements of refractories for ladle mainly include:
* high temperature resistance
* thermal shock resistance
* resistance to the erosion of the slag
* high temperature with sufficient mechanical strength
* the lining has a certain degree of expansion
Q:What are the reasons for the destruction of refractories for ladle?
A: The main causes of damage are as follows:
When the ladle transports high-temperature molten steel, the high-temperature molten steel and slag at about 1680ºC scour and erode it, especially in the slag line part, the scouring and erosion is more serious, and it is an important factor to decide the service life of the ladle.
LF and other extra-oven refining treatment on the unburnt brick damage is serious.
Q:What steel grades are different materials of slide plate bricks suitable for respectively?
A: Different materials of slide plate bricks are applicable to different steel grades. For example,
Al2O3-ZrO2-C slide gate plate can be used as ladle sliding gate plate due to its excellent erosion resistance and thermal shock stability, which can adapt to the casting of various steel grades, and ther are the following materilas based on customer's steel making condition: the MgO-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, and so on.
