Vacuum Degassers (VD-VOD)

Sarralle VD-VOD units from 6 to 300 tonnes can be engineered to operate with steam ejector or dry, mechanical vacuum pumps to achieve deep vacuum with lowest energy consumption in shortest pump down time.

Whereas steam ejector vacuum pumps offer non-complicated, non-destructible technology with very high suction capacity at limited investment cost, dry mechanical vacuum pumps are characterized by instantaneous “vacuum on demand” with extremely low operating costs and elimination of air and water pollution.

Special foaming-slag control enables minimization of ladle slag overflow and pump-down time.

Sarralle engineers and supplies:

  • Vacuum vessels
  • Oxygen lances
  • Sampling equipment
  • Vacuum batch hoppers
  • Vacuum cyclones/bag filters/gas coolers
  • Vacuum pumps
  • Water-cooling systems
  • Electrics & Automation (Level 1 & 2).

Vacuum Ingot Castings (VIC)

Vacuum Ingot Casting is applied to produce forging ingots of 100-800 tonnes weight. The larger the ingot, the lower the required hydrogen content.

Vacuum ingot casting enables sequence casting of several smaller heats into one very large ingot.

  • Liquid steel is degassed in a tank degasser prior to vacuum ingot casting
  • The ingot mould sits in a vacuum tank
  • A pony ladle with vacuum-tight connection to the vacuum tank acts as a tundish, allowing several ladles to be cast through the pony ladle into the ingot mould

Green Energy

SARTECH ENGINEERING S.L. offers a complete scope of engineering, construction, technical and consulting services, specialized in Energy and Waste Recovery projects for environment-friendly industries. We care for a greener world and in our conception, waste is no longer refuse, but an opportunity.

The worldwide demand for energy and resources increases every day and there is a huge need to develop new production technologies and systems. SARTECH considers waste an opportunity and not a problem. Producing and recovering from waste is an added value in an environment-friendly society.

  • Waste to Energy:the first step of the process is to assure that the recyclable material is separated from the waste, in order to recycle as much useful material as possible. Energy can be recovered from waste by different technologies:
    • Incineration: Urban Solid Waste (USW) is burned at 850 ºC in a combustion boiler where the released heat is captured. The heat from the combustion is used to fire a boiler, which in turn generates hot water or steam. The steam powers a turbine and a generator that produces electric energy.
    • Bio-gas Upgrading: the bio-gas produced in anaerobic digestion plants is treated and converted to bio-methane for the gas gird, using appropriate gas scrubbing and injection technologies.
    • Biomass: we supply energy production systems for many different types of biomass fuel regardless of which end-product the customer may need: heat and steam, electric energy or syn-gas. We have developed different feeding technologies suitable for various types of biomass available across the world.
  • Heat Exchange and Co-Generation projects: SARRALLE have developed solutions for different industries in order to recover the energy produced in the production activities. These solutions work in very different industries: steel-making, cement, DRI, glass a.s.o.
