Uses: This series resistance cycle mode of operation for the laboratory, industrial and mining enterprises, scientific research units for elemental analysis and small size steel hardening, annealing, tempering heat treatment, heating, high temperature furnace can be made of metal, ceramic high temperature sintering, dissolution, analysis, heating. Features: 1, this series resistance furnace shell is made of high quality cold-rolled steel production, surface coating process, using the side door open structure, open and close flexible. 2, the temperature in the box using the enclosed chamber, with electric heating element alloy wire is coiled into a spiral after the furnace walls among the heat when the temperature uniformity, extended service life. 3, high-temperature tube furnace using high temperature combustion tube resistance, silicon carbide as the heating element is installed in the furnace jacket. 4, the high-temperature box resistance furnace with silicon carbide in the furnace is installed as a direct heating element, high thermal efficiency. 5, the series resistance furnace insulation materials used 0.4-0.6 lightweight foam insulation bricks and ceramic fiber cotton to reduce the amount of stored heat and thermal conductivity, resulting in the furnace heat storage capacity, shorter heating time, the surface temperature is low power consumption amount is greatly reduced.
