Tubular furnace electric furnace is a standard energy saving type of cycle operating furnace, super energy saving structure, using advanced composite furnace lining structure, electricity saving 30%-40%, suitable for precision casting industry and mold shell heating, high efficiency, much lower than fuel oil, coal cost. The thermal materials of the tubular furnace are made of high quality energy-saving light foam bricks and thermal insulation products. Tube furnace temperature regulation is convenient and safe, as long as the adjustment function button, the temperature control can be realized, so as to avoid the trouble of oil nozzle regulation in the fuel furnace. It has the advantages of stable temperature control, superior performance, low energy consumption and clean furnace. Completely solve your environmental pressure.
Good thermal insulation performance with good refractory; The heating element is made of high resistance alloy wire and placed on the shelf brick around the furnace. Or the tubular furnace with silicon and carbon rod heating material, which can be recycled by two cars, has high thermal efficiency and high productivity, saving about 20% energy compared with the electric furnace of ordinary cars. Using silicon carbon rod or high temperature furnace wire as heating element, long service time, fast heating speed, good roasting effect, less waste, high rate of finished products after pouring. The whole body of electric roaster 41 has uniform heating, long service life, safety and reliability. The special silicon carbon rod for stainless steel precision casting mould shell furnace is the ideal energy-saving product to replace electric furnace wire and coal carbon furnace.
The opening and closing of the furnace door and the entry and exit of the trolley are mechanically driven and equipped with an electrical interlock. The trolley can only move when the furnace door is raised or closed to a certain position. The bottom of the furnace is made of heat-resistant steel castings. The working temperature of the furnace can be automatically controlled by using the electric oven with the control cabinet. The unique flue technology completely solves the problem of high water content and temperature rise of industrial water glass mold shell. Under the same heating condition, the temperature of tube furnace can be raised from 1200 ° C to 1270 ° C in only 10 minutes in a fibre-lined furnace, while that of heavy traditional furnace can be raised from 70 ° C in only 70 ° C, which can save 60 minutes in heating time.
It can be seen that the lining resistant materials of tubular furnaces are different in energy saving and operating cost. Refractory fiber is a new type of energy - saving refractory. In neutral and oxidizing atmosphere, it can maintain good tensile strength, toughness and fiber structure, with good thermal stability, chemical stability, low bulk density, low thermal conductivity, low thermal capacity, high thermal sensitivity, set fire resistance, heat insulation, light energy saving in one.
