Fireclay and High Alumina Brick

Get Latest Price

We manufacture and export Fireclay and High Alumina Brick. Alumina is an excellent engineering ceramic, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness. It is also an electrically insulating material, with a high electrical resistivity, increasing with purity.

Acidic Ramming Mass

Get Latest Price

Introduction:

The role of Acidic Ramming Mass in steel melting through induction Furnace is very important. Due to its important property to with stand thermal shocks without developing any cracks due to interrupted power supply which is the case through out our country We have taken initiative to develop acidic ramming mass of high quality silica Quartz having heavy density.

Product:

Our ramming mass is a product of super snow white crystalline quartz having 99.90% Silicon dioxide (SiO2) and manufactured under strict quality control and calcined to eliminate the scaling tendency in stabilized form, where silica neither expands nor contracts It is suitable for with standing higher temperature up to 1720 °C

Specifications:

Sio - 99.90%
Al2O3 - 0.02%
Free from Iron contents
Softening Point: 1280 °C
Porosity: 50
Compression St: 350 Kg /CM2
Bulk Density: 2.00 to 2.2 Ton/M3
PCE Value ASTM No.: 31-32

Important Features:

For the first new lining the requirement of Acidic Ramming Mass is almost 50% of the Furnace capacity in weight.
Remove iron or steel contents by powerful magnet.
It is required to be preheated to 70-80 °C. So as to eliminate moisture during summer months In winter season or rainy season. the mass should be preheated at a temperature of 140 - 150 °C. then after cooling it down to 50 - 60 °C mix thoroughly 0.8 to 1.5 percent boric acid according to the size of the crucible.
Usually 12% of boric acid of medical grade is used for furnaces up to 3 tons Capacity
Store the Ramming mass in dry and dust free area.

Our Acidic Ramming Mass:

Has got three Categories as under:

Grade M1 Suitable up to 1.5 Ton furnace capacity.
Grade M2 Suitable for 2 to 3 Ton furnace capacity.
Grade M3 Suitable For 5 Ton furnace capacity .

In addition to all we guarantee more lining life with our material compared to any other. While sending your quarries and orders please do specify the capacity of furnace and type of steel you are manufacturing to enable us to give you the correct combination of Material and advise.

Application:

Our Acidic Ramming Mass is used by mixing boric acid 0.8% To 1.5% according to the type of metal Low for Steel and high for cast iron melting. Complete lining guidance can be furnished as required according to the size of furnace.

Packing:

Standard Packing available in 50 kg. HDPE bags & 1 or 1.25 MT Jumbo bags with liner inside, or as per customer requirements.

Bottom Pouring Sets

Get Latest Price

Bottom Pouring Sets are shapes made from different fractions of refractory grog, plastic fire clays and non-plastic clays. The different fractions of these raw materials are mixed and pugged for fully homogeneous mixing. The mixture obtained hence, is then pressed in high capacity presses to give the desired shape and size. These pressed shapes are fired in tunnel kiln at high temperatures of 1300?C. The bottom pouring shapes are generally made in two qualities; 30% alumina and 40% alumina. The bottom pouring sets can also be made in higher alumina grades if required.

Special Characteristics:

Perfect shape and sizing
Accurate fitting of male-female combinations
Highly resistant to thermal shocks
Eliminates carbon deposits
Prevents brick failure at high temperatures
Increases life of brick lining to great extent
