Short steelmaking process system （EAF - refining - continuous casting - continuous casting production model）will be the new production process of 21st century , steel production, the advantage of compact layout process, short production cycle, good quality single variety and high production efficiency .
Steelmaking generally use large, high power or ultra-high power electric furnace, eccentric bottom tapping, or high impedance DC power supply, while intensive smelting. Therefore, the refractory material put forward higher requirements, but also promoted the development of refractories. This class generally use water-cooled electric furnace wall and the lid, the lid triangle is high-purity corundum castable refractory, and furnace bottom slope that is melting tank with a dry vibration material and ramming material, also used when damaged repair of such material.

In the non-ferrous casting and industrial use frequency induction melting furnace and other parts of the ditch, dry vibration material can be made of aluminum lining, also made good use of effects.
Dry vibration material and ramming material a new varieties of monolithic refractories in recent 10 years. The key technology is self reaction in high temperature, self-sintered product must be high-temperature phase material, and particle size distribution and binding agent is very important. The material begins with the introduction of an electric furnace brought soon to localization. Factory 150t UHP EAF with Ogilvy & Mather, dry vibration material, the average life expectancy of 260 times, 305 times the highest level. When domestic wet vibration ramming mixes, the average life expectancy of 282 times, up to 332 times.
