Chemical combination tower cavity used for metal atomization powder process

[0024] refer to Figure 1~4 : A compounding tower chamber for metal atomization powder making, comprising a compounding tower shell 2 and a compounding reaction chamber 1 installed inside it; Made of carbon-carbon composite material, the top of the chemical reaction chamber 1 is provided with a connecting chamber 11 connected to the atomization spray plate, and the bottom is provided with a drain pipe 15; the side near the drain pipe 15 is also provided with an air inlet pipe 14 ; The connection between the connecting chamber 11 and the chemical reaction chamber 1 is provided with an exhaust nozzle 12, and the side wall of the chemical reaction chamber 1 is provided with a centralizing assembly 13.

[0025] The temperature resistance of the carbon-carbon composite material is ≥2000°C.

[0026] The high-temperature anti-oxidation coating is coated with a graphite high-temperature anti-oxidation coating that can be used at a temperature ≥ 1800° C., and its thickness is 3 mm. The

[0033] Compared with Example 1, there are the following differences in a compound tower chamber for metal atomization pulverization in this example:

[0034] The temperature resistance of the carbon-carbon composite material is ≥2500°C.

[0035] The high-temperature anti-oxidation coating is coated with graphite high-temperature anti-oxidation coating that can be used at a temperature ≥ 2000° C., and its thickness is 5 mm.

[0036] The working principle and method of use of a compound tower chamber for metal atomization pulverization of the present invention are as follows: the compound reaction chamber 1 is fixed in the compound tower shell 2 by the support member 16 at the bottom of the centralization assembly 13; Into the compound reaction chamber 1, the gasification reaction gas (such as O 2 , CO 2 or N 2 ), the gas gradually reacts with the metal powder falling from the top of the compound reaction chamber 1 from bottom to top, and oxidizes, carbonizes or nitrides the met
