Item # 3352/C209     Cast Link Belt Line

This is a complete cast link belt line rated at 7000 lbs / HR.

LOADER: Loader is 84” wide x 48” deep x 42” high. This has a mechanical clamp down for the bins.
Bins can be placed in dumper. Bin is locked in Dumper 180º to dump the product in a hopper. Hopper
is plastic lined so as not to damage the fine threads on bolts.

Weight control to the furnace is by Metro weight control system. From hopper product is put on a vibratory
feeder, weighed and goes to another vibratory feeder, weighed again, and then it trickles down to washer.
On the loading system number of lbs required for loading is punched in and computer updates the files every
20 sec. to give an accurate load to the furnace.

WASHER: Wash tank is 132” long x 46” wide x 51” high. It has a steel belt conveyor 39” wide.

GAP MISER: Parts from washer fall on a gap miser conveyor which feeds parts to the furnace. This is a
mesh belt 226” long. This transfers the part to the cast link belt. With this system parts fall gently on the
cast link belt and gap time is reduced. Parts do not roll off like in conventional cast link belts. Belt is 52”
wide and 226” long. 96” of this belt goes inside the furnace. Parts get pre-heated in this area and belt
discharged on to cast link belt. Height of discharge is minimal.

of controls with Zone 1 9 Burners Zone 2 6 Burners Zone 3 6 Burners Zone 4 6 Burners Tubes are U
tube cast with heat recuperators. Controls of carbon potentials and temperature control is via Honeywell
controllers. SCADA system is by Metro weigh scale. Load can be monitored through the furnace for
temperature belt speeds carbon potential feed rate live with software in the computer. Burners are Unirad
Maxon burners. Belt is supported on 29 rollers on top and there are 17 return rollers in the bottom.
Bearings on the rollers except the drive rollers are carbon bearing.

TEMPER: Temper has 3 zones of control each with separate safety control. 3 fans with 20 HP motor. Temper
 belt is 84” wide mesh belt. Mesh belt rides on steel rod conveyor with side links 3” high. Temper has a heat
zone 39’ long.

SOLUBLE OIL CONVEYOR: This sits ate the end of Temper. This is a metal hinged Mayfram belt 30” wide.
This is set 90º to the furnace.

Total length of furnace if put in one line except soluble oil conveyor is 17.5’. Burners tubes and rollers all can
be removed from one side. Furnace can be installed in a U configuration also.

Item # 3365/C103     Electric Furnace Co. Roller Hearth Normalizing Line:

This line, which was purchased new approximately 10 years ago was only used for a very brief period of time and is in immaculate condition! Originally sold for $2 million US it is complete and currently in indoor storage. All electric with heavy duty rolls on 9" centers it has an atmosphere cool and a temper. Uses 36" X 36" trays. 40" wide work zone, 20" high, 3-4,000 pounds/hr. Brick lined with an operating temperature of 1650F. Vendor is asking $450,000US. Complete drawings are available on request. If you are looking for a large normalizing line and are considering new I would suggest that this is a good way to save $1.5 million. By the way the company that disassembled the furnace took video tape for reassembly purposes. 

Uses a 36" x 36" tray with a 20" high door opening. A typical roller hearth cycles at a preset time and advances the load, one tray at a time, through the furnace. Based on the dimensions, the normalizing furnace should hold 13 trays at a time and the tempering furnace should hold 16 trays. If you advance the normalizing furnace every 18 minutes, you will move a tray through the furnace in about 4 hours. If you advance the tempering furnace every 15 minutes, you will move a tray through the furnace in about 4 hours.

Both the high heat and the temper have atmosphere. The high heat max temperature rating is at least 1650°F.  New Information & Pictures
