Crucible Melting Furnace Casting Die Casting Waste Aluminum Burning Aluminum Melting Reflex Furnace

First of all, the melting point of the charge itself is the key factor of the temperature of the charge, the melting point of the charge of a certain composition is certain, so the temperature in the combustion process is the decisive factor.

1. When smelting refractory furnace charge, the temperature difference between furnace gas and furnace charge is small, the heat transfer from furnace gas to furnace charge is small, and the production efficiency of reflector is reduced. When melting the easy furnace material, the temperature difference between the furnace gas and the charge is large, the heat transfer from the furnace gas to the charge is large, which improves the production efficiency of the reflector.

Water is the first precipitate in the combustion process of coal. Increased moisture affects the calorific value, which lowers the furnace temperature, affects the fuel, increases heat loss from the exhaust gas, and increases the heating surface of the rear heating surface. Water also affects the speed of the flame. When the water content increases, the flame will travel slower.

3. Calorific value of charge and excess air coefficient during combustion. The higher the calorific value of fuel, the higher the combustion temperature of fuel, the higher the temperature of furnace gas, the more heat transferred to the charging pool, the faster the melting rate of charging.
