Refractory Stop, For Use with HRG Drill Guide

The Delta Controls Model HRS Refractory Stop prevents refractory castable or mortar from entering the thermocouple nozzle during backup lining of the reactor. After the refractory has cured, the HRS is removed and the refractory is drilled using the Model HRG drilling system.

The castable surface must be flat, smooth, and even with the vessel shell’s interior surface for the HRW refractory well to be positioned and supported correctly. The HRS is fitted with an adjustable seal plate that is positioned to be flush with the nozzle bottom when even with the inside surface of the vessel shell.

Alternative methods used to prevent the entry of the castable materials, such as taping, troweling or placing objects in the nozzle do not provide a suitable result.

Refractory systems using insulating brick in place of insulating castable do not require the HRS.
