Product Description:

Ladle upper nozzle & collecter nozzle
With the characteristics of high strength, good thermal shock resistance, oxidation resistance, scouring resistance, erosion resistance, small reaming and long service life, etc.

Long nozzle
They have excellent properties of thermal shock resistance, abrasion and corrosion resistance, bake free and long life.
Breathable ring is composited inside nozzle bowl, achieves argon-blowing protection of nozzle end, and prevents secondary oxidation which satisfying requirements of high pure steel.

Submerged nozzle
They have excellent properties of abrasion resistance and oxidation to molten steel, thermal shock resistance, corrosion resistance to slag.
The nozzle outlets are special handled by materials with good abrasion resistance in order to guarantee stable outlet angle of molten steel, and satisfy requirements of molten steel flow field design of crystallizer and production, which ensure stable liquid level.

Q:What is refractory brick? What is refractory clay? ?
Fire clay refers to the light pouring material, raw materials adopt light porous clinker, bauxite, cenosphere, silicon dioxide ultrafine powder and alumina micropowder. Use calcium aluminate cement CA-80 as binder. Refractory brick is burned from stone powder and clay put in 1300 degrees' kiln
Q:What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
Exterior wall uses red brick, preheating zone uses lightweight high aluminum bricks, burning zone uses mullite, cooling zone uses ordinary refractory bricks
Q:What is the refractory brick of the electric furnace?
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:What material is good of refractory bricks?
It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials
Q:What material are used to burn firebrick?
Alkaline series of refractory bricks /, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick /
Q:how to test the high alumina refractory brick mixed alumina?
The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:Scheme of cement kiln replacing 40 meter refractory brick kiln
If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).
Q:Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
The burner block is heavy, its using temperature is high, while thermal insulation brick is light and its using temperature is lower than heavy brick.
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
Yes, but the cost is high, refractory material should be the most affordable at present.
