The apparatus includes an inductor that is connected to a high frequency power source with a power controller to cause the power source to direct a given power to the inductor at given rotational heating positions of the crankshaft. A master controller creates output signals to control the power controller. The apparatus and method includes a first multi-surface hardening station with inductors for all of the main bearing surfaces, a second multi-surface hardening station with inductors for some of the orbital pins and a third multi-surface hardening station with inductors for the remaining orbital pins. Total indicator run out (TIR) is measured after the first station to adjust the heating process in the third station to produce a straight crankshaft.
Systems and methods are presented for automated induction hardening of crankshaft bearings while controlling the crankshaft TIR, in which one or more first bearings are hardened by induction heating and quenching, followed by measurement of the crankshaft TIR. The measured TIR is then evaluated and one or more second bearings are hardened using a second induction heating power profile and a second quench flow profile, at least one of which is selectively adjusted according to the measured crankshaft TIR. In this manner, the hardening of the second bearing(s) can counteract any bending or warpage caused by the first hardening process to control the resulting final TIR of the crankshaft.
A device for the simultaneous induction heating of elements with complex shapes e.g. camshafts to provide a localized surface hardening of the elements to a constant depth all over the periphery of the element. This is accomplished by causing that the outside profile of the element to be heated and the inside profile of the inductor are geometrically similar and the clearance is minimum thus providing a tight coupling. The device consists of a construction (5) including inductors (1), (2), (3), (4) and hydraulic pistons (7) that move the mobile portion (10) of each inductor, thus allowing the loop to be opened and the element to be positioned. The hydraulic pistons can be replaced by pneumatic pistons or electromechanical actuators. The inductors consist of two portions: portion (10) is moved by pistons (7) and portion (11) is integral with the construction. Once the surfaces (12) of the two portions are brought into contact with each other, they form a closed loop having the inside profile geometrically similar to profile (8) of the element to be heated.

The groove receives therein a guide rail which is disposed intermediate a pair of slide rails upon which the plate slides. The shape of the groove allows the plate a small amount of lateral rotation to minimize jamming during travel. Adjacent plates pivot upon contact with each other to automatically adjust their orientation during travel through the furnace. The leading and trailing faces of the plates thus contact one another over a larger surface area to reduce damage to the plates by reducing the pressure therebetween.

A removal assembly includes a first removal mechanism which removes the load supports from the furnace section and a second removal mechanism which removes the loads from the first removal mechanism to facilitate the continuous downstream movement. The first removal mechanism preferably includes a parallelogram-type four-bar linkage for lifting the load supports and lowering them onto the second removal mechanism. Entry and exit plenums are connected to respective ends of the furnace section to provide a controlled atmosphere within the furnace section. The pusher and removal assemblies are timed with opening and closing of various gates of the plenums to maintain the controlled atmosphere.
A pusher furnace includes furnace sections having respective susceptors, a slide rail extending through the furnace sections for sliding pusher plates thereon and an alignment assembly for aligning the susceptors and slide rails of adjacent furnace sections. A support structure spaces the susceptors from insulation therebelow to protect the insulation from degradation from contact with the susceptors. The susceptors are slidably mounted on the support structure to accommodate thermal expansion and shrinkage of the susceptor. The upstream end of the slide rails have beveled upper edges to help prevent the pusher plates from catching thereon. The upstream ends are also laterally tapered to reduce the degree of force encountered should a pusher plate catch thereon. Adjacent insulation members have expansion joints filled with a refractory felt. The susceptors slidably and sealingly engage exhaust ports to allow for thermal expansion and shrinkage of the susceptor without damaging the exhaust port.

INDUCTION COIL HAVING INTERNAL AND EXTERNAL FARADIC RINGS
An induction furnace includes a pair of induction coils with a pair of faraday rings disposed between the induction coils to substantially prevent mutual inductance between the first and second induction coils. The induction coils preferably have a different size circumference and may be coplanar. The prevention of mutual inductance provided by the faraday rings is particularly useful for a pusher furnace in which adjacent furnace sections are heated to different and rather specific temperatures.
A compression system for an inductively heated pusher furnace controls movement of susceptors during thermal contraction thereof. The system includes a plurality of furnace sections each having a susceptor wherein each susceptor abuts an adjacent susceptor and wherein the susceptors include first and last susceptors. A compression plate abuts the first susceptor to apply force thereon toward the last susceptor to keep the susceptors in abutment with each other during contraction of the susceptors during cooling thereof. An actuator for moving the compression plate is preferably automatically controlled by a computerized control system. The susceptors together form a tunnel through which pusher plates travel and have overlapping joints which seal against the escape of gasses and allow for a degree of susceptor contraction without forming a gap therebetween even in the absence of compression of the susceptors.

Guidance system for pusher plate for use in pusher furnaces
A pusher plate for use in a pusher furnace includes a shaped guidance groove in its lower surface which preferably has a bow-tie shape with a narrower central section and wider ends proximate the leading and trailing faces of the plate. The groove receives therein a guide rail which is disposed intermediate a pair of slide rails upon which the plate slides. The shape of the groove allows the plate a small amount of lateral rotation to minimize jamming during travel. Adjacent plates pivot upon contact with each other to automatically adjust their orientation during travel through the furnace. The leading and trailing faces of the plates thus contact one another over a larger surface area to reduce damage to the plates by reducing the pressure therebetween.

A casting system includes a filtration assembly including a filter vessel housing spaced filters pre-heated to a temperature approximating a pouring temperature of molten material to be filtered to prevent breakage of the filter due to thermal shock from contact with the molten material. Preferably, an induction coil is used to inductively heat a susceptor adjacent the filter vessel or inductively heat filters which themselves serve as susceptors. Typically, the filter vessel is disposed below a pouring vessel and above a mold, pour cup and any sprue system used and is heated independently from the same. The filters are heated during pouring to facilitate flow of the molten material therethrough whereby very fine filters may be used. Spacing of the filters enhances flow control and allows a head of molten material to form whereby dross floats to the top of the head to prevent its entry into the mold.
A continuous- or intermittent-melt induction furnace useful for heating and/or melting semi-conductor or other materials includes an induction coil, a susceptor switchable between open and closed electric circuit modes, and a crucible. The susceptor is inductively or resistively heated in the closed circuit mode and transfers heat to material in the melting cavity to make it susceptible to inductive heating. The susceptor is then switched to the open circuit mode and the susceptible material is directly inductively heated to melt remaining solid material. A cone-shaped flow guide in the melting cavity improves molten material flow to improve the ability to draw small-particle material into the melt and increase crucible life due to improved heat uniformity. A trap passage communicating with the melting cavity and an exit opening in the crucible allows the flow of material through the exit opening to be controlled by pressure differentials on either side of the trap passage.

An induction heat treating process with a remote sensor for monitoring the duration of energization of an induction heating coil each time the induction heating coil is consecutively cycled. An identifying tag is preferably attached to, embedded within the induction heating, coil or within, the surrounding area of the induction coil and transmits a signal to a remote counting sensor that .is preferably triggered by and responds to the change in voltage generated as the coil is energized. Alternative means of measuring a cycle may be implemented. The output data from the sensor provides useful information for determining the lifespan of an induction heating coil. Predicting the lifespan of a coil optimizes production by anticipating failure and. replacement of a coil during a predetermined down time, limiting on-site inventory, and revolutionizing, the billing cycle based on a per cycle cost while decreasing overall production costs and improving inductor coil quality.
