Refractory material segment plug used in ladle for gas blowing
Product Description
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.
In steel making today, gas blowing in a ladle is indispensable for improvement of steel quality and for continuous casting.
In this field, we dominate the market with our Porous Plugs and Slot(Slit) Plugs.
Our purging plug is characterized by their high strength, good erosion resistance and corrosion resistance, high blowing rate and good safety. They are widely used for continuous casting ladles and refining ladles.
As the ladle tends to develop in larger scale, the melting temperature and time have been improved significantly, which makes the using environment for refractory materials more and more strict. Therefore, it is necessary to further improve the performance of purging plugs and blocks to meet the increasing demands in current steel making technology.
Xiazhimu manufactures various types of gas purging plugs for ladle satisfying each metallurgical and application requirement of customers.
The major goal of the Purging Plugs and Systems is to stir steel in ladle, aiming at:
1)Desulfurization
2)Reduction of non-metallic inclusions
3) Uniform distribution of temperature and alloy additives
4)Steel cleanliness
Segment Plug Type
The segment plug is composed of a central blowing unit realized by hydraulic pressed alumina plates, then sintered at high temperature. This unit is contained in a refractory body casted in alumina spinel.
Main characteristics of this type of plug are: easy cleaning and inspection ; resistance to action of the oxygen lance.
Slot plug type
The slot plug is composed of a monolithic body realized in alumina spinel in which a wide range of gas blowing slots are placed.
The peculiar characteristic of this kind of plug is the possibility to vary, also a lot, its flow rate thanks to different blowing surfaces.
Porous plug Type
The porous plug is made of a monolithic body realized in alumina zirconia, pervious to gases but impermeable to the molten metal.
Main features of this type of plug : creation and homogeneous diffusion of very small bubbles for the moving of molten metal bath.
Hybird Plug Type
Based on Alumina spinel castable, with pressed fired porous plate as blowing pack, and additional slots all around.
This plug guarantees, the blowing in the most severe working conditions through its combined porosity, an insignificant maintenance, an easy adjustable gas flow (high / low gas flow) and a perfect stirring performance at low gas pressure.
Preassembled sets( purging plug and well block)
Preassembled sets consisting of purging plug and block are equipped with a transport hook as a standard and provide the following advantages:
1)Easy hading
2)Precise motar joint
3)Optimized lifetime of the installed purging plug
