Carbolite GLO Annealing Furnace

1、 Product Introduction:

The characteristic of GLO furnace is a vacuum sealed furnace tank and symmetrically distributed heating wires around it. The heating wire is embedded in ceramic fiber insulation material. The iron chromium aluminum alloy heating wire is Kanthal APM.

GLO furnaces are often equipped with vacuum pump systems that can extract oxygen from the furnace before heat treatment. To ensure the lowest possible oxygen content, nitrogen will be used to flush after vacuuming. This process will cycle several times to create a pure atmosphere inside the furnace. The establishment of vacuum takes priority over nitrogen atmosphere. Vacuum assisted equipment will quickly create a clean atmosphere environment, consuming only a small amount of nitrogen. After reducing the oxygen content as much as possible, inert gas is introduced to a slightly positive pressure, and the heat treatment process is initiated.

Under ambient conditions, the maximum temperature of GLO annealing furnace can reach 1100 ° C. If necessary, the furnace door can serve as an independent heating zone. Gas is introduced into the GLO furnace tank, preheated by the radiation layer of the furnace door, and diffuses from front to back. There is a waste gas discharge outlet on the back wall of the GLO furnace, which is used to discharge the waste gas released during the heat treatment process of the sample.

GLO furnace can be manually controlled or automatically controlled. The stove can be selected in sizes 5L, 10L, 40L, 75L, 120L, 260L, 400L, 550L, 600L, 850, 950, and 1300L. The furnace can is made of high-temperature resistant steel alloy (1.4841), and other materials can also be used according to customer needs.

When equipped with appropriate safety devices, the furnace can operate in a reactive atmosphere (such as hydrogen). If the furnace requires hydrogen gas supply, an automatic operating system and all safety devices must be selected. The hydrogen safety device includes a nitrogen flushing tank for emergency situations. All devices comply with SIL2 standards.

The furnace adopts a compact and space saving design. Optional adhesive dispensing process package for dispensing or pyrolysis. The exhaust combustion device is used to treat exhaust gas. Due to the exhaust gas being heated, condensation will not occur.

GLO furnace can be equipped with a rapid cooling system. The furnace can be cooled by external air or by introducing inert gas directly into the furnace for cooling.
