alumium casting

Material: Alumium Process: Alumium Foundry Dimension: BSP1"*BSP1/4" thread,BSP1/2"*1/8" The metal plates require preheating in the early stages of the firing. This can be achieved with gas burners, or even a wood fire. Once the firebox has got hot the radiant heat will keep the plates hot and the burner becomes more efficient the hotter these plates become. Working principle

There is a definite ratio between the burner port area and the venturi throat. Typically, depending on the kiln or furnace back pressure, gas pressure and burner head design, the venturi throat area should be approx. 40-50% of the total burner port area. Mismatching may result in a decrease in mixture velocity producing inadequate burning or at worst "flash back". Low rates can be achieved by using a preheat pilot.
