Abstract
The invention provides a device and a method for adjusting sintering atmospheres. When only one of an oxidizing atmosphere, a neutral atmosphere and a reducing atmosphere is needed in the whole sintering process of a product, the ratio of air to a fuel gas is accurately adjusted by use of a proportional valve, after the fuel gas goes into a kiln, the fuel gas is combusted sufficient to establish the desired atmosphere for sintering the product, and in the sintering process, due to the stability of the proportional valve, unstable introduction proportion of the air or the fuel gas can be avoided so that the sintering of the product cannot be affected; when two or three of the oxidizing atmosphere, the neutral atmosphere and the reducing atmosphere are needed or the three atmospheres need to be alternated in the sintering process of the product, firstly, the ratio of the air to the fuel gas is accurately adjusted by use of the proportional valve, the mixed gas is introduced into the kiln and then sufficiently combusted to reach the oxidizing atmosphere, and then the throughput of the fuel gas is adjusted by use of the proportional valve so that the air and the fuel gas go into the kiln in a desired ratio to achieve the sintering atmosphere needed by the product until the sintering of the product is completed. The device and the method for adjusting the sintering atmospheres has the advantages of simple structure and convenient operations.
