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.

Description

A kind of device and method adjusting firing atmosphere
Technical field
The present invention relates to a kind of adjusting means is and in particular to a kind of device and method of regulation firing atmosphere.
Background technology
Nowadays, firing firing of product is ceramic body to be positioned in kiln fire, and kiln generally comprises kiln body, combustion Burning system, control system etc., and in combustion system, air and gas proportion input passing ratio valve to control, combustion system is selected Proportioning valve can ensure that air is effectively adjusted according to set proportion with combustion gas, and it not only can ensure the automatic control of temperature System, and also ensure that stable the automatically controlling of kiln atmosphere.Under normal circumstances, air-fuel ratio (i.e. air and the fuel of proportioning valve Input ratio) determine after, be difficult to air-fuel ratio is adjusted change.
In actual production process, fire product and adopt which kind of firing atmosphere in sintering procedure, basis can burn till product In the composition of raw material and sintering procedure in formula, the physical reaction situation in each stage is determining.If firing product in sintering procedure When only needing a kind of firing atmosphere, kiln combustion system adoption rate valve fully achieves requirement.If but firing product and exist If needing in sintering procedure firing atmosphere is made a change, being difficult to adjust and change it is impossible to burning till because of proportioning valve air-fuel ratio Atmosphere is adjusted changing, and this will bring a lot of inconvenience to sintering procedure, affects firing of product.
Content of the invention
Present invention is primarily targeted at solution the problems referred to above, provide one kind can adjust change in sintering procedure and burn till gas The method of atmosphere.
