The heating temperature, heating time and the atmosphere in the furnace affect the degree of burning loss of gas in the gas forging furnace. Today, the small series introduces the method of reducing the burning loss of gas.
1. Burner of heating furnace
Blacksmithing heaters generally come in pairs, with one combustion-supporting agent and one fuel injector. The nozzles near the material are usually fuel injectors, which also reduce oxidation.
2. Oxygen-enriched combustion
In the study of oxygen-enriched combustion technology, it was found that when oxygen was enriched 28% to 30%, oxidation was not increased but decreased.
3. The air-fuel ratio
The air-fuel ratio is generally controlled between 0.95 and 1.05 to eliminate the oxidizing atmosphere.
4. The furnace temperature
Furnace temperature is not a good or bad determinant, high temperature, fast oxidation rate, low temperature, heating time will increase, a variety of materials and conditions have specific indicators.
5. Furnace temperature distribution
A uniform and reasonable furnace temperature distribution can reduce the amount of oxidation to a certain extent.
