I am using advanced foreign equipment structure, combined with our raw materials, the research and development RC-WN products outside the hot air cupola suitable conditions. In the use of raw material conditions, the use of imported equipment to overcome the existing problems, with increased hot metal temperature, reduce carbon monoxide emissions and reduce coke consumption, reduce the burning, stable chemical composition of the molten iron, improve casting genuine rate, the production of high grade quality castings, reduce production costs and other properties. Reached the cupola furnace smelting international level, to meet the competition after the entry of a firm technical basis for our machinery, casting product quality.

Product Features:

1, the external heat supply air: the use of external heat (caused by gas flaring) preheated hot air structure, optimize the use of high-quality hot air technology, make full use of cupola furnace gas chemical and physical heat exchanger using advanced technology.
2, water cooling structure: The routine use of evaporative cooling or water-cooled furnace shell rain, using no lining or thin lining operation.
3, plug-in air: The copper plug outlet.

Main economic indicators:

Iron temperature:＞1500°C
Supply air temperature:400--600°C
Coke consumption ratio:1：8---1：10

Stable chemical composition of iron, carbon, silicon and increase desulfurization effect is remarkable, hot metal composition and stability, reduce Feo content within the slag and the general cupola ratio: casting genuine rate of 20-30% over 30 days of continuous production, productivity 5- 50t / h.
