What is Silica Ramming Mass?

Acidic Ramming Mass, also known as Silica Ramming Mass or Mix, is used in Coreless Induction Furnaces, for melting of scrap. High performance Silica Ramming Mixes (also known as Acidic Ramming Mass in generic terms), designed to minimize erosion in induction melting.

The raw material of silica ramming mass is high quality quartz, mixed with high quality boric acid. Silica content of its raw material is more than 99%. Generally we will add 1 % to 1.5 % to premix with quartz, but it can be changed as per customers’ requirements. According to customers’ feedback, this product can be used for 20 heats to 40 heats on furnace capacity from 10MT to 40MT. Our monthly production capacity is 10,000MT/month.

Silica Ramming Mass Advantages:

High erosion resistance.

High bonding strength.

Short lead time.

Free engineering services to guarantee service life.

Here’s the following list of the benefits of silica ramming mass, which makes it the most commonly used refractory lining material for induction furnaces.

Meticulous and organized lining ability

Consistent performance

Long shelf life

Optimal bulk density

Wear resistant

Free from sintering agent

Induction furnaces are used for melting cast iron, mild steel and various alloy steels in foundries and making of steel in mini steel plants using sponge iron. Lining is the important part of induction furnace. Furnace performance is directly related to the performance of its lining. Well laid and stabilized lining results in smooth working of furnace, optimum output, and good control of the metallurgical reactions. The lining practice best suited to a particular furnace depends upon the capacity and design of the furnace, operation practice adopted during making of a heat, and furnace output.

For successful and consistent performance of the lining, the important aspects are :

(1) use of proper grade and quality of the lining material, 

(2) careful and systematic lining practice

(3) consistency in working conditions.  

The selection of refractory for the furnace lining is based on the type of slag generated during melting. There are three types of ramming masses namely (1) acidic, (2) basic, and (3) neutral. If the slag contains high amount of acidic components then a silica (SiO2) lining is used. For slags with a high basicity index, magnesite (MgO) linings are the choice. Neutral refractory has become the new trend for lining in induction furnace. The ramming refractory mass used for neutral lining in the induction furnace consists of a mixture of alumina (Al2O3) and sintered MgO blended according to a certain granulometry. Such blends are tested prior to their use for estimating their corrosion resistance and mechanical behaviour. The most commonly used lining material for induction furnace is acidic lining. It normally consists of high purity silica ramming mass.
