The electric furnace structure is mainly composed of a furnace body, a crucible, a combustion system and a temperature control system.
The furnace shell is welded by section steel and steel plate, and the interior is made of heavy high aluminum brick to form the furnace lining. The insulation layer adopts aluminum silicate refractory fiber and diatomite (or vermiculite powder) bulk material structure to improve the furnace body's thermal insulation performance. A solution discharge port is left at the bottom to prevent the crucible from rupturing, and the solution in the leaking furnace can be discharged.
The aluminum melting furnace adopts a fully automatic temperature-controlled burner imported from Italy, diesel fuel, and the furnace flame combustion is fully rotated and burned according to the design angle, and then the secondary waste heat is used through the flue to save energy.
The crucible is a Tianfu graphite crucible, the operating temperature is about 800 ℃. The crucible rested in the center of the furnace. The molten metal is tilted in the crucible for insulation.
There is a leak hole at the lower end of the front of the furnace body. In the case of a leaky solution formed by cracks in the crucible due to corrosion and oxidation, the solution in the furnace can flow out of the furnace through this hole, so as to prevent the heating element and the furnace lining from being damaged more. The leakage hole usually uses several layers of paper, etc. Flammable materials are blocked to prevent cold air outside the furnace from entering the furnace.
Temperature display uses a digital display and a thermocouple to measure temperature.
The flue is a movable type, which is made of steel sheet into an outer shell, and a high-temperature castable material or fiber cotton is used to form an insulation layer.
The company can design and manufacture oil-fired melting furnaces according to customer requirements.
