Impermeable and breathable brick for ladle

The product is made of high-purity raw materials and fired at high temperature. It has the advantages of thermal shock resistance, corrosion resistance, and impermeable steel. Composed of permeable gas components, safety alarms, seals, etc., argon is mainly supplied through anti-permeable gas components. It is used for bottom argon blowing in steelmaking LF, LF-VD, CAS-OB refining ladle and continuous casting ordinary ladle The process can be cleaned with less or even no cleaning, high blow-through rate, long life, and good safety. Compared with slit-type air-permeable bricks, this product is safer, energy-saving and emission-reducing, and can effectively reduce costs and increase efficiency for customers.

Toetoetra:

Impermeable parts

The anti-seepage components with patented and unique formula can completely avoid cleaning or intermittent cleaning when in use, which greatly increases the service life.

2.Unique number

Ny biriky sy ny biriky ny biriky isaky ny biriky misy rivotra dia samy manana ny isany, mba hahafahantsika manara-maso ny famokarana sy ny fampiasana ny toe-javatra ary manome fiarovana azo antoka kokoa noho ny rafitra fitantanana kalitao henjana sy henjana kokoa.

3.Block design

Ny famolavolana patanty sy tokana ao amin’ny sakana dia afaka misoroka tsara ny sakana tsy ho vaky, ary ny fiarovana dia avo kokoa mandritra ny fanadiovana!

Overall program

The longer service life of the brick core provides the possibility of splitting and reforming the whole, and solves the dilemma of many customers between safety and output. The unique patented embedded design greatly improves safety and prevents problems before they happen!

5.Safety warning

On the right is the real shot during normal use, and on the left is the company’s newly designed and patented safety warning device, which is easier to observe and judge during use, making you more at ease in operation.
