RJF square pit Furnace
RJF square pit electric resistance furnace called the square resistance furnace, also known as a straight feed furnace, pit furnace, annealing furnace square, rectangular pit furnace, pit furnace, tunnel furnace, heat treatment furnace pit. Because between box-type furnace and pit furnace square pit furnace between, there are manufacturers classified in a box furnace. Square pit furnace is mainly applied to all kinds of steel castings, metal materials, especially the long straight material tempering, annealing purposes, with easy loading, good sealing performance and low labor intensity. The furnaces and electric control cabinet supporting the use of automatic temperature control.
Square pit furnace with high efficiency, easy to operate; low maintenance costs; long life; with chain protection device prevents faults and accidents arising due to misuse.
Square resistance furnace by the partial furnace, lid, heating control system, etc., the square resistance furnace steel furnace by having channels, angles, welded steel plate processing, solid and reliable. Furnace ceramic fiber blanket insulation materials used as furnace insulation materials, light weight, small thermal storage losses, small heat loss, energy-saving effect, long life, good body sealing performance, easy maintenance and other advantages. High temperature resistance heating (0Cr25AL5) through a special alumina ceramic nail fixed to the furnace suspended four weeks so that it can maintain strong when lifting, shaking occurred not because of loosening. Furnace sealing: To make a good sealing performance electric furnace, the furnace body around the ad hoc seal groove, the bottom lid is provided with sand sealing blade, when the lid is on the furnace cover the sand right on the sand seal sealing knife tank, so as to achieve the sealing effect. Square resistance furnace heating for the two-zone heating, each has a separate temperature measurement and control system, temperature control system uses intelligent temperature to achieve temperature inside the furnace and temperature control, easy to operate, supporting control system also a tape recording and sound and light over-temperature alarm.
