Low-Temperature pit Electric Furnace

RJ3 series Low-temperature pit Furnace is a new typeof standarded energy-saving cycle operating well furnace, mainly for metal materials, metal parts for tempering, annealing and other heat treatment. and steel annealing, aluminum alloy, light alloy quenching, solid fusion processing, aging treatment.

Structure description:
In order to make workpiece beheated uniformly, the lids are installed with heat-resistant stainless steel shaft and the blower hot air circulating fan. the heating process of the workpiece, hot air in the Al-alloy Ageing Furnace cycles up and down in a high speed to ensure workpiece to be heated uniformly. To ensure safe operation limit switch is fitted near the vicinity of lifting bodies, the switch is linked with the power control cabinet of the furnace. Iid close when connects to power. When the lid is opened, the limit switch cut off power supply immediately, thus heating elements are cut off at the same time so as to ensure safe operation. Hypothermia well furnace factory supports automatic temperature control cabinet and thermocouple.
