Blackening furnace
Blackening furnace powered rotor, stator, silicon steel, high speed steel cutting tools, tooling fixtures, machinery parts, sintered iron-based powder metallurgy products for black surface oxidation treatment, blueing.
Furnace black black black works by chemical agents, under certain circumstances and the workpiece furnace black dense oxide film to form iron oxide (This process is commonly known in the industry as "black", "blue hair "," blue "). Prevent the workpiece played rust, corrosion and other effects in daily use environments.
Black furnace due to the use of chemical reagents to black so called chemical furnace black, black early chemical reagents is mainly sodium carbonate, sodium hydroxide, sodium phosphate, sodium silicate, sulfate, nitrate and other ingredients, causing environmental pollution, blackening agent companies have developed environmentally friendly recycling of blackening agent but higher costs. Black with a black stove all this.
Blackening furnace configuration features:
1 Furnace using 1Cr18Ni9Ti stainless steel.
2 insulation materials made ??of high quality aluminum silicate cotton.
3. Electric heating alloy using ribbon or filament, and easy maintenance.
4 unique hot air circulation system, so that indoor temperature distribution.
5 Use a water jacket cooling fan and lid.
6. Various protective atmosphere can manually adjust the flow according to process requirements.
7 black furnace temperature control using PID experts with no overshoot algorithm imported smart meters, triggered by zero-power module to control the heating power. Down 2 to 3 zone temperature control, the furnace temperature is more uniform.
8 with a power meter, power consumption can be measured.
9 offers over-temperature alarm system, when the furnace temperature exceeds the set range can audible alarm signal, and cut off the heating power.
10 Independent control cabinet can conveniently control, centralized control may also be in the control room.
11 As the black furnace temperature uniformity, there is a certain pressure steam in the furnace, the oxide film products, good compactness, uniform hardness.
