Based on the uncertainty of vertical burning speed and the abnormal sintering states in lead-zinc imperial sintering process, an intelligent integrated predictive model for burning through point (BTP) is proposed. First, a fuzzy T-S predictive model based on the character of piecewise linearity is established to deal with the uncertainty of vertical burning speed. Then, considering the ...

In addition, field assisted techniques can reduce sintering times while selective laser sintering (basically, 3D for metals) is slower and the traditional oven process is slower still. The addition of a liquid phase will also speed up sintering times. However, faster sintering times can lead to reduced density and residual porosity.

The role of liquid phase in sintering process can be summarized as follows: (1) The unmelted solid ore particles in the sintering process are bonded to each other into blocks and wet their surface. After cooling, the ore particles will be tensioned under the action of surface tension, reducing the gap between solid particles.
