The Advantages of Large-scale Continuous Mechanical Enamel Furnace are:
(1) Wide range of product types and sizes. Small products can be fired in baskets, divided into 4-7 layers, while larger products can be used for bathtubs or water heater liners, etc.
(2) High production efficiency. For producing the same daily necessities, the output of a large furnace can reach that of more than two ordinary mechanical furnaces.
(3) Low fuel consumption. For producing large and heavy products, the furnace's thermal energy utilization rate is over 80%.
(4) Low outer wall temperature, close to room temperature, improving workshop production conditions.
(5) Large product volume entering the furnace, and a very slow firing conveyor chain speed of 0.5-3 m/min, achieving low-temperature long firing, resulting in a higher grade of product appearance and more stable quality.
Using this type of furnace requires adherence to certain process standards; otherwise, problems may arise. When producing daily necessities using multi-layer firing, it is necessary to prevent iron filings from the upper layers and frames from falling off, otherwise the quality of the lower layers will be affected. Since the frame material for holding the products is made of high-grade heat-resistant steel, material selection is particularly important. The furnace temperature should be controlled between 780 and 820°C. On the other hand, due to the thicker enamel layer in domestic porcelain, the design of the drying chamber must be given sufficient attention; otherwise, the drying speed will not keep up with the kiln's production speed. For large-scale mechanical enamel firing furnaces, our domestic technicians, after years of research and exploration, are now able to design and manufacture them independently and have considerable practical experience. Fuels include electricity, coal gas, natural gas, liquefied petroleum gas, and light diesel oil; there is also practice with heavy oil. The large furnaces manufactured are not only used domestically but also exported to many countries. Domestically manufactured furnaces are superior to imported furnaces in terms of technical performance and price. The price of domestically manufactured kilns is only 1/2 to 1/3 of that of imported furnaces of the same specifications, while the main technical performance parameters are basically the same, such as furnace outer wall temperature, furnace internal temperature uniformity, heating time, temperature control and adjustment, fuel consumption per unit area, and component lifespan. Fuel consumption per unit area and component lifespan must be combined with the operating temperature of the kiln; the lifespan also depends on whether it is single-shift or continuous three-shift production. Foreign production is mostly single-shift.
