The application discloses a high-performance aluminum nitride ceramic rapid sintering method and belongs to the technical field of ceramic materials, and comprises the following steps: preparing ceramic raw materials according to a formula: uniformly mixing high-purity aluminum nitride powder, a sintering aid, a hydrolysis-resistant agent and a solvent, and drying under a nitrogen atmosphere; the ratio of the high-purity aluminum nitride powder, the sintering aid and the hydrolysis-resistant agent is 1:1%-3%:0.5%-1.5%; primary sintering of the ceramic: heat-press sintering the uniformly mixed aluminum nitride powder under a neutral or reducing atmosphere at 1650-1850 DEG C and a pressure of 20-30 MPa for 10-60 min, so that the density of the aluminum nitride powder reaches more than 99%; secondary sintering of the ceramic: sintering the primary-sintered aluminum nitride ceramic under a reducing atmosphere at 1850-2000 DEG C under normal pressure for 1-6 h. The prepared aluminum nitride ceramic not only has high heat conduction performance, but also has high sintering efficiency; meanwhile, the problem of waste gas generated in the degreasing process is avoided, and the environment is protected.

This invention belongs to the field of iron and steel smelting technology, specifically providing a sintering system, its control method, computer equipment, and a readable storage medium. The control method includes: determining the total carbon input of the sintering system based on the raw material mass at the feeding mechanism and the gas / fuel gas flow rate at the ignition mechanism; determining the total carbon emissions of the sintering system based on the gas flow rate, carbon dioxide content, and carbon monoxide content in the flue; obtaining the carbon consumption by subtracting the total carbon input from the total carbon emissions; determining whether the carbon consumption is less than a preset threshold for the total carbon input; if the carbon consumption is less than the preset threshold, determining that the combustion process is incomplete and generating a reminder message. This invention determines whether sintering is complete by calculating the overall carbon consumption of the sintering system and reminds the user to analyze the reasons for incomplete sintering, effectively improving the sintering efficiency of the sintering system and reducing sintering costs.
