Refractory Installation System (RIS)

Induction Furnace Heating Equipment

The Refractory Installation System (RIS) performs two functions: it simultaneously dispenses dry refractory between the furnace wall and form and automatically deaerates the material.


INSTACENTR® Form Centering Tool

for Furnace Lining Installation & Replacement

A set of three InstaCentr® spacing tools are used to quickly and accurately center the form(er) within the furnace, for the entire length of the form(er) in about 10 minutes. For furnaces 12 tons or larger, four tools are required.


Refractory Vibration System

The Refractory Vibration System is comprised of two components

The electric bottom or floor vibrator plate and an electric sidewall vibrator unit

Both units are operated from the furnace deck by a control stand.
