Use the work piece swinging type isothermal quench craft manufacture the energy conservation durable industry electric furance. The fusing liquid medium heating work piece, like the nitre salt class, the alkalis, the oil class and the low melting point metal and the alloy and so on, the nitrate furance heating work piece, the rate of heating is quick, the oxidized decarbonization is light, is advantageous for the point hardening, the isothermal quench and many kinds of thermochemical treatments. Especially is suitable for the railroad locomotive, the ball mill backing, the steel ball, the breaker hammer head Austria - shell body anti-friction material isothermal quench.
Structure description:
Mading up by the furnace body, the stainless steel crucible, electrically operated toward the multiple swinging material frame, stainless steel fast cold box, the heating unit and control the warm cabinet to be composed automatically, may use the different resolver, carries on components quenching, the tempering heating, the isothermal quench to cool, the liquid thermochemical treatment and other kinds of crafts, the furnace body are welded by the section and steel plate, the furance surface are made by δ=14mm board, the nitrate furnace lining uses the ultra light quality high strength 0.6g/cm3 micro bead refractory brick, clamps the stratification aluminum silicate textile fiber, the furnace lining and the furnace shell fills the heat preservation inflation heat preservation powder, the entire structure for the standard energy conservation furnace lining, the nitre salt furance's heating element uses the thick diameter 0Cr25Al5 high temperature resistance wire to circle spiral-shaped according to the average temperature cloth silk law, Places in the furnace lining puts on the silk brick, puts the silk brick to use the front part to go up 20° against falls the silk brick, the resistance wire is not easy to drop out. Uses the heat-resisting stainless steel plate to weld densely crucible makes, and after this factory X light crack detection. Uses as the isothermal quench salt furance when arranges fast cold package four which in crucible the heat-resisting stainless steel makes, and the installment has the electrically operated reciprocation swinging type material frame on the furnace body, the work piece places in material, in the nitre salt fluid the reciprocal motion, achieves the average temperature, the isothermal quench effect. In addition provides the compressed air stainless steel air feeder, in crucible the base composition porous jet pipeline, causes the nitre salt fluid fast circulation tuck dive, achieves in the nitre salt fluid any temperature even consistent, controls the warm electricity cabinet's coordinate use automatically through the nitre salt furance, may cause the quenching work piece in the very short time needs the rapid chilling in any craft temperature which to the isothermal quench the automatic constant temperature.
