Heating Elements 15 Kva For Annealing With Water Sprinkles To Form In Various Shapes And Coils.

Salient Features

• All Operational Controls - Air, Water And Solid State Electronic - Are Machine Mounted, For Easy Access, Safe And Simple Maintenance.
• Weld Sequence Controller, Sophisticated Quartz Timer With Squeeze, Weld, Hold And Off Timings With Single/repeat Cycle Facility, Weld Timing Being Controlled By Thyristor Circuit, Heat Controllable From 5% To 95%.
• Electrode Cushion Control Adjusts The Descent Of The Upper Electrode To Any Desired Speed And Completely Eliminates 'hammer Blow'.
• Sturdy Ram Assembly Permits High Speed Operation.

SPECIAL FEATURES

• Thyristor controlled electronic timer with electronic heat control, to give heavy duty high speed operation, providing smooth, stepless and accurate adjustment of the welding current.
• High quality roller bearings carrying the roller shafts, guaranteed longer-life of the roller heads.
• Leak proof joints at much lower costs than conventional welding.

Advantages

By employing Metal gathering many of the well known technical limitations and disadvantages of mechnical upsetting can be overcomed.

• Simultaneous heating and forming in one machine.
• Almost unlimited gather in one operation. The mechanical upsetting limitation of about 3 x dia. no longer applies. The modern engine valve has an upset length of up to 20 x dia. and lengths of upto 40 x dia. are commonly electro-upset.
• No longitudinal flash is formed such as is unavoidable in a split-die mechanical upsettler.
• No waste of heating energy or material. Outside of the upset volume can be precisely controlled to allow subsequent, "flashless" forging in closed dies.
• Always ready for instant use, no warm up period.
• Energy efficient, about 0.35 - 0.40 kwh / kg.
• Minimal scaling because of simultaneous heating and gathering. Improved die life in subsequent forging operations.
• No environmental pollution by emission of heat, fume or exhaust gas.
• Free upsets can be finished forged without re-heating and so save time and energy.
• Consistant heating temperature through the use of thyristor control.
• Optimal grainflow and fault free surface. The unheated bar length remains unchanged.a

Anti Roller Bars

Heating with 3 phase Dc upto 300 Kva upto 1000C and lifting and dropping on conveyor chain for quenching in oil tank for heat treatment. Can also be used for heating & bending.

ADVANTAGES

• Lower energy consumption.
• Immediate start of heating operation.
• Low scale formation.
• No decarburization of the skin.
• Good soaking of the bars.
• Compact design, smaller outer dimensions.
• No foundations required.
• Shorter heating times with high temperature precision.
• No Pollution
