Energy-saving and environment-friendly high-temperature electric melting furnace

Abstract

The invention discloses an energy-saving and environment-friendly high-temperature electric melting furnace. The energy-saving and environment-friendly high-temperature electric melting furnace comprises a control cabinet and a furnace body. The furnace body is composed of a hearth and a furnace lining. The hearth is composed of three insulating layers. A temperature measuring element is arranged on the back face of the furnace body. The hearth is of a semi-open type structure, and the hearth is filled with an aluminum oxide hollow ball plate. The high-frequency voltage transformation principle is adopted for saving electricity and energy, a plurality of silicon-molybdenum rods or silicon-carbide rods are used for heating, the temperature rise is fast, the effect is good, the high temperature of 1,600 DEG C can be generated, and the requirement for the temperature of pressure casting or crystal glass raw material smelting is highly met. A corundum plate, a silicon-carbide plate and a silicon oxide plate or a graphene plate are arranged in the hearth, crystal raw materials can be prevented from being attached into the hearth in the smelting process, and the cleanliness and transparency of crystal glass in the sintering process is guaranteed; meanwhile, the multiple insulating layers are arranged, dissipation of heat is effectively reduced, and resources are saved; and the external temperature of the furnace body is very low, and potential safety hazards of scalding are reduced. Noise is avoided during electric heating work, and the effects of safety, energy saving and environment friendliness are truly achieved.

Description

technical field [0001] The invention belongs to the field of crystal glass production equipment, in particular to an energy-saving and environment-friendly high-temperature electric melting furnace. Background technique [0002] In the die-casting process of the crystal glass industry, it is necessary to heat and soften the crystal glass raw materials. The existing technology utilizes the combustion of liquefied gas and industrial oxygen mixed gas to achieve the softening of crystal glass rods for die-casting. The furnace is made of ordinary refractory bricks, which has no heat preservation effect and the temperature in the furnace dissipates with the air, which consumes energy, has potential fire safety hazards, pollutes the environment, and lacks practicability. Another existing electric furnace uses silicon carbide rods directly connected to the 380v voltage, and the furnace insulation is also made of ordinary refractory bricks, which consumes a lot of power and has low ...

The furnace is made of ordinary refractory bricks, which has no heat preservation effect and the temperature in the furnace dissipates with the air, which consumes energy, has fire safety hazards, pollutes the environment, and lacks practicability

Another existing electric furnace uses silicon carbide rods directly connected to the 380v voltage, and the furnace insulation is also made of ordinary refractory bricks, which consumes a lot of power and has low efficiency. The bottom of the furnace is also paved with ordinary refractory bricks. Aluminum powder is sprinkled on the bottom of the furnace to prevent it from sticking to the furnace, and the production cost is high

And cannot produce high-quality transparent products
