-Slot Plug(slit plug)

Slot plug is the most common structure in purging plug.
The gas channel could be designed and customized according to actual on-site using conditions, including refining steel grade,
refining workmanship, ladle capacity, temperature, hydrostatic pressure of liquid steel etc.
This can achieve the best blowing effect for purging plugs, ensure the longest service life, safety, stability and best air
permeability.

-Porous plug
Porous plug has better porosity and permeability.
Production technology is adding carbon-containing compound into mixture, since carbon-containing compound can burn out without
residue at low temperature, so we adopt low temperature burning out intermediate materials to get the initial porosity.
In porous type plug, inside distributes interpenetrating gas channels in different sizes.
When blowing stop, the steel and slag from ladle will infiltrate into the deep areas of the plug, to form a secure layer on working surface.

-Overall breathable brick:

This product adopts high purity raw materials, through vibration casting and low temperature heating process workmanship.
Function is blowing argon gas via purge plug to ladle.
With the feature of high strength, good thermal stability, erosion resistance and abrasion resistance.
Widely used in steel plants LF, LF-VD, CAS-OB refining ladle

FAQ:
Below are some FAQ 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: 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.
