For optimum gunning and refractory performance the gunning material is essentially the same as the original refractory (plus binder material), but with a size distribution of 4mm maximum. The applied thickness is typically in the range 10–30mm and a vessel can normally be used again after 3–5 minutes.

Many of these early contractors used equipment designed for the concrete industry to "field mix" the various refractory components of a castable in the field. One of the most common refractory castables used in fired heaters and in some FU equipment was the "LHV 1:2:4" castable.
Coke Oven Refractory Repairs. Coke oven battery is a refractory structure, contained within a steel and / or concrete exoskeleton. This exoskeleton is held together in the lateral direction by a series of tie rods between steel buckstays. The buckstays are vertical steel beams located on the ends of the heating walls between the ovens.

Thermal Energy Equipment: Furnaces and Refractories. Porosity: The apparent porosity is the volume of the open pores, into which a liquid can penetrate, as a percentage of the total volume of the refractory. This property is important when the refractory is in contact with molten charge and slag.
The absolute refractory period is responsible for setting the upper limit on the maximum number of action potentials that can be generated during any given time period. In other words, the absolute refractory period determines the maximum frequency of action potentials that can be generated at any point along the axon plasma membrane.
