Furnace Curtains Are Installed Before The Opening of Furnaces

Furnace curtains are installed before the opening of furnaces. This curtain keep the heat contained within a furnace and ensure a consistent temperature when dealing with a variety of manufacturing processes. They are hung at the openings and at the discharge of furnaces that keep the heat contained or inside the furnace to separate heat zones by stopping radiating the heat losses to some extent and make surrounding environment comfortable enough to work. The curtains are made from Glass roving, PTFE (Polytetrafluoroethylene) coated glass or stainless steel, High Silica or Ceramic fabrics. Occasionally they are also insulated by inserting wool between two layers of fabrics. All of which are best for keeping the heat/atmosphere from escaping the furnace, while its suppleness allows unhampered movements of materials. They can also be covered with S.S. Wire netting to take care of abrasion.

The tight mesh construction minimizes air flow and provides a highly reflective surface Furnace curtains that have a high strength, corrosion resistant steel wire which can withstand heat up to 2300.F (1260C). Installing furnace curtains is one of the simplest and most effective ways to conserve energy and save money. They are most commonly used by steel mills, coal burning power plants, tubing manufacturers, aluminum extruders and car radiator manufacturers. They are also designed to serve as energy saving curtain walls in high temperature, continuous furnace operations.

Furnace Curtains can be manufactured in 330 Series Stainless Steel or higher or lower grade alloys if required. The curtain consists of panels that are equipped with a simple hanging device, which bolts the curtains into specified position. For easy hanging, options like hangars or loops are hanged at the top of the curtains which does not overlap the panels and as work leaves the furnace, the curtain panels swing back to a vertical position. Flexible curtains of tightly woven stainless steel mesh high temperature alloys are available to fit openings of virtually any height or width.

Benefits in using Furnace Curtains

-They are economical, efficient replacements.

-Individual curtains can be purchased and replaced easily with low maintenance.

-Improves fuel consumption and conserves energy

-Flexibility allowing the product to enter and exit the heat chamber with ease.

-Immediate closure of furnace opening after product passes through door.

-Reduction in glare and temperature in the work area.

-Maintains a more constant furnace temperature.

-Maintenance free; no mechanical or electrical devices to monitor.

-Manufactured to fit any size opening.

-Improves uniform heating of slabs, billets, and blooms
