Reorder: Electrotherm to install and commission the second 4.5 meter rotary hearth furnace to
a major manufacturer of turbine blades forgings


Electrotherm was awarded with a reorder for an electrical heated 4500mm rotary hearth furnace equipped with SiC u-shape heating elements for forging and heat treatment within temperature range of 1650°F to 2250°F (900°C to 1230°C). The furnace is a gas tight furnace. The atmosphere gas system is fully equipped for endothermic and nitrogen gas. The installation and commissioning is schedule for this autumn. For more information about these types of furnaces, e-mail info@electrotherm.co.il.

Two 1000 mm rotary hearth furnaces are delivered to a French manufacturer of aeronautical construction for precision forging

Electrotherm was contracted to manufacture and supply two 1000mm rotary hearth furnaces by a French manufacturer of aeronautical constructions. The furnaces implement a "one in-one out" philosophy. They are designed with a rotary speed of 2 r.p.m and include station indexes. Electrotherm responsiveness to the customer specifications and ability to supply within a tight delivery schedule was key in winning the order.

NEW PRODUCT RELEASE :    CS/ELRH
Integrated Cooling System For Rotary Hearth Furnace Total Mobility

Water flow indica-
tor and water
temperature gauge

Cooling the oil is essential when sealing the furnace with an oil-seal ring. The CS/ELRH, Air-to-Water cooling system ensures total rotary hearth furnace mobility on the production floor. Two 1000 mm rotary hearth furnaces are delivered to a French manufacturer of aeronautical construction for precision forging

How It Works

The system utilizes an Air-to-Water heat exchanger with a cooling capacity of 1.5KW. It is installed on the roof of the furnace and has an independent control system. A water pipe runs from the cooling system to the oil sealing ring underneath the furnace. Within the oil sealing ring there is an inner water pipe cooling the sealing oil.

In the event of a water circulation pump or an air fan overload, a warning signal is automatically sent to the rotary furnace control panel.

Technical Data

Cooling capacity 1.5 KW
Water thermometer range 0°C º 80°C
Dimensions* 600W x 500H x 500D (mm)
Flow Switch 1
Axial air fan 1
Water circulation pump 1
Pressure gauge range 0º30 psi
Compatible to furnace model no. ELRH10, other sizes available

Benefits

• Complete furnace mobility
• Cooling system eliminates the need for long cooling pipes from the water tower to the furnace
• Unnecessary heat loss and energy is saved by elimination of cooling pipes
• Reduction of labor- Elimination of pipe line changes
• Easy maintenance – easily accessible and removable dust filter


NEW PRODUCT RELEASE :
HOT OIL CONTAINER FOR THE MELTING AND REMOVING OF UREA

Electric
hoist to
raise the
basket

A melting container, constructed as a rectangular pot filled with oil for melting Urea containing embedded blocks with blades. The parts to be melted are placed in a basket, which is immersed in the oil. The oil is heated to a temperature of 170° C and melts the Urea. The melted Urea pushes the oil upward and the Urea settles at the bottom for easy recovery by opening the heated valve located at the bottom of the pot to a small container.

Features

• Electrical lifting device
• Closed side chamber with exhaust
  fan for oil vapor emissions
• Heated valve for Urea recovery
• Safety clasp to secure lid when
  opened
• Removable rack in pot for placement
  of basket

Technical Data
