Electric Curing Furnace for Heating Furnaces and Industrial Furnaces [Case Study Introduction]

Improved temperature distribution, increased production, and energy savings. This electric curing furnace achieves stable temperature distribution through the optimization of heater arrangement and effective utilization of exhaust heat.

【Example Introduction】 This is a curing furnace for resin-impregnated glass tubes used in storage batteries. ◆ Traditionally, the temperature distribution was not uniform in both the width and length directions, and production adjustments were made by varying the feed speed. ◇ By reviewing the arrangement of electric heaters and introducing hot air utilizing exhaust heat, the temperature distribution has improved, allowing for an increase in production volume. ~ In this case ~ The heat from the deodorized exhaust gas treated by the exhaust gas treatment system is recovered through a heat exchanger and reused in the furnace. This not only helps to equalize the temperature inside the furnace but also contributes to energy savings. The heat source can be electric, gas combustion, or hybrid, making it applicable to various works (heated objects). 【Specifications Example】 ● Application: Curing furnace ● Processed material: Glass tube ● Feed speed: 8–10 m/min ● Temperature: 230–300℃ (furnace atmosphere) ● Heat source: Seize heater ● Heater capacity: Total 80 kW ● Effective dimensions: W2040×L8500×H210 ● Exhaust gas treatment: Direct combustion deodorization device (LPG burner) ● Equipped with an exhaust gas treatment device (manufactured in-house) that deodorizes volatile components, achieving energy savings by introducing its exhaust heat into the furnace.

Inclined immersion type electric heater holding furnace [oxide reduction type]

Solving various issues of the aluminum holding furnace! "1. Reduction of oxides" "2. Improved maintainability" "3. Safety" "4. Energy conservation"

<Problems with Reflective Electric Heater Holding Furnaces> - The atmosphere temperature above the aluminum molten surface is high at 850°C, which promotes the generation of oxides. <Problems with Under-type Electric Heater Holding Furnaces> - Complete draining of the molten metal is necessary during heater tube replacement, which poses safety risks such as leaks. <Problems with Vertical Immersion Electric Heater Holding Furnaces> - The heater tubes are exposed above the molten surface, resulting in significant heat loss from the furnace body and a high occurrence of oxide generation around the tubes. ~These issues are resolved with the "Diagonal" Immersion Type!~ [What is a Diagonal Immersion Type Holding Furnace?] It is a holding furnace equipped with high-efficiency electric heaters installed diagonally downward towards the aluminum molten surface. 1. Reduction of Oxides - Similar to the under-immersion type, the immersion heater is completely submerged in the aluminum molten metal, which suppresses the generation of oxides. 2. Improved Maintainability - The immersion heater tube can be replaced by draining the molten metal down to the lower limit of the molten metal sensor. 3. Safety - Compared to the under-immersion type, there are fewer issues with aluminum molten metal leaks due to the heater's mounting position and structure. 4. Energy Saving - By adopting high-efficiency heaters, the heat loss from the furnace body in the ceiling area is reduced. Holding capacities range from 500kg to 2000kg.
