• Hotwork is the pioneer of the convective heating process, which simplifies refractory dry-outs and heat-ups. The one-sided drying of monolithic refractories is an extremely complex transient heat and mass transfer phenomenon which includes chemical reactions throughout the dry out. Moisture trapped in a refractory lining after a furnace or vessel rebuild is especially detrimental to optimum refractory performance. Network's convective heating method utilizes rapid heat transfer at all temperature levels. Our patented burners produce high velocity combustion, which is accurately controlled from ambient to temperatures in excess of 2500°F (1370°C). This high discharge rate circulates the products of combustion evenly throughout the vessel, regardless of size and configuration, producing overall temperature uniformity. The process results in fast, even moisture removal across the entire refractory lining allowing rapid furnace startups.

  Hotwork has successfully completed dry-outs and heat-ups on:
  

  Rotary Kilns Fluidized Beds Raw Mills
  Alumina Calciners Coolers Mills
  Vertical Kilns Calciners Coal Finish Mills

  Hot work has been tremendously popular in the field of "REFRACTORY DRY OUT" and has numerous equipment to match its work endlessly. We have a special designed set of "HIGH VELOCITY BURNER" to completely remove moisture during the dry out process.

• Furnace Heat up
  Traditionally, small to medium-sized glass furnaces in the Asia Pacific region have been heated-up in 7 (or more) days. This has become widely accepted as the “norm”, and it is perceived that a faster heat-up will result in an abbreviation of the eventual furnace campaign life.
  
  This is a misconception. There is no technical reason why the refractories generally used in container and lighting glass furnace construction can not be heated up more rapidly. The only inhibiting factor is being able to adjust for, and control, furnace expansion.
  
  (Exceptions would be where Dense Chrome blocks and “M” (fused alumina) Crowns are present.) By using the High Velocity burner system, there is no need for such a cautious approach. Your furnace can be safely heated-up from ambient to 1100/1200oC over a 3 or (maximum) 4 day period. This provides a substantial saving to you in terms of furnace downtime.
  
  Over 100 furnaces have been heated-up in India & Abroad over the past 12 years, by (briefly) commencing combustion air reversals from the beginning of the heat-up, thereby pressurizing the furnace and optimizing temperature uniformity throughout, and using High Velocity burners to heat-up in 3 or 4 days (depending generally on the furnace size).
  
  The results show no measurable difference in subsequent furnace campaign life versus furnaces which have been heated up over a schedule twice as long. WHY HAVE YOUR FURNACE SITTING IDLE FOR 3-4 DAYS LONGER THAN NECESSARY ?

• Furnace Draining (Tapping) :

• Cullet Filling :

Hot work offers fast cullet filling systems capable of up to 60 tons per hour. We offer the original "dry" filling equipment where air is used as the medium for conveying the cullet out into the furnace for quick melting and elimination of thermal shock to the fill pockets plus systems to filter out fines or wetting equipment to eliminate the dusting of the superstructure.

• Sulfate Removal :

  Hot work uses special outlet nozzles in conjunction with our unique Hotwork burners to quickly and safely remove sulfates and borates from checker settings to allow the furnace to operate at or near original design parameters.
