B. Structure and performance of the furnace body
Furnace by the induction coil, aluminium furnace frame, reduction box and other components
a. Unduction coil
Induction coil is in the heart of the entire induction furnace, induction coil from the intermediate frequency power supply, generates a powerful magnetic field under the influence of medium-frequency voltage, current, the magnetic metal inside the furnace and eddy current heating coil is the key power conversion of thermal energy. Coil design so it is important for the gifted, the furnace coil is a combination of domestic and foreign intermediate frequency furnace actual use, according to the electromagnetic theory, the preferred option through accurate analysis and calculation determined.
Induction coil with copper pipe. In order to guarantee the reliability of the induction coil, induction coil used brand for T2 (purity electrolytic copper 99.5%), 1 ton furnace wall thickness using 4 extrusion rectangular copper pipe on the special die winding and become, it not only ensures the coil rigid and has the most conductive section. The density of copper pipe, pipe wall thickness. Induction coil when the design considering the influence of the inherent and length of copper pipe, the copper pipe welds and electricity, water diversion area, make each group of induction coil inside without welds..
According to ISO431-1981 standard coil material, uses thick-walled high quality copper From Shangyu Company, copper with minimum line loss, improve the efficiency of coil conversion (provide material list). Induction coil adopts high temperature resistant, high voltage insulation varnish, overall dip coating and vacuum drying, achieve class H insulation class. Induction coil before delivery after 12 kg/cm3 hydrostatic pressure test
Induction coil of the exterior insulation adopts the double forms, the inner coating by electrostatic spraying process with a high-strength insulating resin. Then use the class H class insulation paint leaching paint dry.
Induction coil by welding outer circumference series bolts and insulation stay fixed. After the coil is fixed, its turn spacing error is not more than 2 mm. All the countersunk head bolts, in order to improve the dielectric strength
Induction coil welding are made of silver electrode, does not affect the current liquidity.
b, Furnace frame:composed of primary aluminum and magnesium alloy casting
Furnace frame by two pieces of aluminum semicircle casting furnace and the surface of the upper two pieces of aluminium casting furnace with middle asbestos board, insulation board, and the self contained stainless copper wire rod, asbestos plate with heat and blocking current generating circuit to make aluminum furnace heating effect, insulation board with insulation and tighten sensors column does not move, make whole aluminum shell furnace is strong and durable.
Furnace frame part reserved when the design safety coefficient. Ensure furnace frame has sufficient strength, carrying the maximum charge run smoothly. Angle is greater than 95 degrees.
c, Reducer tilting furnace system:
Using RZS type reducer. RZS type reducer for special dedicated reducer, it is mainly used for medium frequency electric furnace, high temperature furnace automatically dumping operations, mechanization in advance, to ensure the quality of casting to reduce labor intensity and improve productivity play an important role, also can be used for automatic welding, automatic, automatic assembly line workpiece transposition etc. Turn the operation requirements.
RZS reducer is the key product electric furnace overloading, this product is a secondary drive worm gear and worm reducer, RZS431, input power respectively 2.5 kw, this product has small volume, large speed ratio, transmission self locking, low noise advantages. RZS431 are equipped with manual and electric control device, electric control with tilting furnace control box contactor three phase electric conversion control motor and reversing a tilting furnace oven, with extension and handle button control. Manual operation, pull a hand wheel and worm gear off the first grade, and movement to secondary worm reducer directly by the handwheel to by the second worm gear drives the output shaft. This product is convenient for installation and debugging,
There are two main ways RZS reducer assembly, left to the output shaft and output shaft to the right. This series reducer is a NPC deputy cylindrical worm gear drive, worm grinding, can improve the machining accuracy, convex concave tooth profile meshing, the Angle in the direction of circumferential velocity increase, to produce the best lubricating oil film, improve mesh, can improve the tooth surface fatigue strength, prolong service life. Convex-concave tooth smaller curvature (curvature radius is larger), reduced the contact ability, improve the bearing capacity; Output shaft bearing spacing is bigger, to improve the output stiffness, increased transmission stability, without other supporting bearing, simplified structure, reduced volume, improve the ability of long axis stirring; Type output shaft is a hollow structure with an inner cone, cone agitator shaft passes through the cavity to locate the shaft head nut to lock, the assembly is very convenient, easy maintenance; then motor through a pulley connected to the deceleration gear, not only increasing the ratio range, underway buffer.
