SILICA RAMMING MASS
[EIRI/EDPR/1084] J.C.: 9728
INTRODUCTION
Acidic Ramming Mass, also known as Silica Ramming Mass or Mix, is used in Coreless Induction Furnaces, for melting of scrap. It is a dry lining refractory that can be used for all types of iron and steel and in both mini steel plants as well as foundries.
High performance Silica Ramming Mixes (also known as Acidic Ramming Mass in generic terms), designed to minimize erosion in induction melting. We are the first company in India to have a three-stage beneficiation, purification process plant and mixing plant. The highly controlled Silica and a particle size distribution has been kept at an optimum level, according to the furnace capacity and make, gives a high density, trouble free and consistent linings. We are the only company to have separate grade for different furnaces.
Application
It is widely used in the low cost melting of ductile and malleable iron, Stainless Steel, Mild Steels, Low Alloy Steels, all types of iron foundry operations, ranging from periodic melting to continuous holding applications. In addition to being suitable for many iron alloys, such as Ni-hard, Ni-resist and chrome irons, it may also be used for selected high temperature nonferrous applications and is suitable for coreless induction furnace of all sizes and types.
It can be installed employing any one of the several techniques utilizing vibrators, mechanical impacting tools or hand ramming.
Chemistry
Reactivity of the metal, sintering characteristics, reactivity temperature and strength of the lining has been kept in mind while formulating the Chemical composition. During service these grains transform to Tridymite and Cristobalite with a very large increase in volume. This places the partially constructed lining under high compression, forcing the particles very tightly together and making refractory lining: The low to high temperature modifications of Quartz, Tridymite and Cristobalite take place rapidly. Above 16500C, the volume of all forms of Silica remains relatively constant. This is why linings show outstanding resistance to thermal spalling and cracking above this temperature.
