Aluminium bale out furnace

Crucible type electrical / LPG / Natural Gas / Oil fired, Melting and holding furnace for pressure die casting, die casting, low pressure die casting. These furnaces are now fitted with recuperator for recovery of heat.

Aluminium Flash Annealing

Flash annealing of aluminium rolled / formed products is an important operation for utensils, pressure cooker, collapsible products. Aluminium products are heated and suddenly cooled to acquire required properties. The designs changes from case to case basis.

Batch Flash Annealing Oven

Circles, Plates loaded on trolley inserted in a box Oven, heated by electrical LPG or diesel. Twin trolleys with two door Oven is most popular design with strong recirculation.

Continuous Mesh Conveyor Oven

Mesh belt conveyor Ovens provide good results with heavy section, if cooling to be incorporated the length increases.

Continuous Roller Conveyor Oven

Small slugs related products are loaded in to baskets and passed through an Oven continuously and cooled outside.

Continuous vertical flash annealing Oven

1. In this latest technology the plates and Circle remain in vertical condition, length wise. Only top and bottom edges touch the conveying system resulting into scar less annealing.
2. The use of these furnaces dimensions' shrink to minimum, width wise, height wise material can be loaded quickly and easily.
3. This enables induct excellent uniformity so the properties.
4. Higher production capacity.
5. For flats curricle, plates, cassette type loading unloading take place.
6. Cooling within the Oven is also incorporated.
7. Electrical Gas fired versions are available.
8. PLC/SCADA Control temp. And movement mechanism management synchronized for the process.

We offers heat treatment furnaces, rapid quench furnaces. Annealing normalising hardening solution treatment heating forge heating tempering aluminum solutionising stress relieving ductile iron full annealing.

Solar Powercan be directly (DC supply) used forHeating Furnacesduring daytime. These furnaces are also fitted with Automatic gas burners. As solar energy reduces, gas heating starts. Solar retakes over next day morning. This combination ofSOLAR+GASreduces operating cost up to60%compared with Government Power supply tariff. The Cost of Investment is recovered in less than a year or even less if100%depreciation is availed.

Scheme:

• 100 kW Heat Treatment Furnace needs 624 sqmt panels to be mounted on the roof/open space facing south.
• No Inverter. No Battery required.
• Approx. 800-1000 kWh (Units) are generated which will directly heat your furnace.
• If solar power goes short than required for process, gas burners will automatically start and makeup the heat.

Most Recommended for:

• Heat Treatment Furnaces.
• Aluminium melting, holding, Annealing Furnaces
• Powder Coating, Paint-Baking Ovens
• Core, Mould Batch or Continuous Ovens.

Automated batch ovens for core
