Our factory supplies ASTM A297 Grade HK40 grate nozzle manufactured by precision investment casting (lost wax casting) technology.

As professional metal casting manufacturer, we produce high-performance HK40 grate nozzle for high-temperature furnace, boiler and thermal processing equipment.

Air Nozzles, also called air cap, air button, bubbling cap, are used on air distribution plate of Circulating Fluidized Bed boiler or Bubbling Fluidized boiler. The boiler air nozzles are designed to direct airflow in the boiler to improve fluidization, eliminate dead zones and push debris away from the boiler. The boiler bed air nozzles produced by Baoding Guokun are very durable and are highly acknowledged among our customer due to their abrasion resistant nature. Based on 25 years casting experience, Baoding Guokun can use the suitable advanced metal casting techniques to produce the customized boiler nozzle. And we assure to deliver a defect free range of our metal casting products in a stipulated time frame.

The boiler bed air nozzles are made from many metals, including cast iron, cast steel, alloy steel, stainless steel and heat-resistant steel. They can be customized to suit the different fuels used in the boiler.

Investment casting techniques for cast steel boiler air nozzle, stainless steel furnace air nozzle, cast steel boiler air cap.

Investment casting: Investment casting is an industrial metal casting process based on lost-wax precision casting, generally used for producing complex-shaped metal components that require tighter tolerances, thinner walls and better surface finish than other sand cast parts. Baoding Guokun can produce various investment casting parts in low-carbon steel, mild steel, alloy steel, stainless steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.

ASTM A297 HK40 is a widely used heat-resistant alloy casting material, featuring excellent high temperature oxidation resistance, creep resistance and long service life under continuous high temperature operating conditions. The lost wax casting process enables precise dimensional tolerance, smooth casting surface, and flexible complex structure fabrication for all kinds of casting grate nozzle.
