To clarify the utilization of flue gas desulphurization (FGD) gypsum as the retarder of cementbased materials,the effect of the properties of the slag cement with different tempemtuIe treatment of FGD gypsum was studied. The results reveal that in the case of adding the same amount, the setting time of cement shortened with the increasing of heat treatment temperature of FGD gypsum. The influence of different heat treatment processes on the strength of cements was not obvious and the strength development was good. The water consumption of normal consistency for cements changed slightly. Stability was qualified.

The actual lethal effect is traditionally determined by calculating the sum of the lethality rates, given in the reference literature. However, to calculate the heat treatment process F-effect for development new sterilization and pasteurization regimes of canned foods, it becomes necessary to vary the parameters of the base temperature and heat resistance characteristic value of the microorganism test culture. To automate the process of computing, the authors developed the software «Heat treatment process lethality calculation» which calculates the lethality rates, the heating lethal effect and the actual lethal effect (F-effect) values of the canned food heat treatment process. In the paper, the software mathematical calculation formula, graphical user interface and functionality are described. The example of pasteurization conditions selection for canned food «Trout in olive oil with the addition of pickled pineapple» in the tin can No. 2, based on the obtained results from the developed software for calculating the actual lethality of the canned food heat treatment processes, is shown.

Generally, metals are easy to wear, so material modification is needed to increase hardness to increase the material's resistance to wear and tear. One way is to do a hard chrome plating process using the electroplating method and then continue the heat treatment process. This research was conducted to observe changes in the mechanical properties and microstructure of S45C steel that underwent hard chrome and heat treatment processes. This research was conducted by inserting S45C steel as a cathode into hard chrome liquid and using lead (Pb) as the anode. A positive (+) current powers the anode, the cathode has a negative current (-), the voltage used is 12 V with a duration of 60 minutes. After the cathode was coated with hard chrome, a hardness test was carried out, then continued with the heat treatment process using a temperature of 850°C for 30 minutes. The hardness test results show an increase in the hardness of S45C steel that has been coated with hard chrome, with a hardness value of S45C steel 202.70 VHN, S45C hard chrome steel 998.63 VHN. The highest hardness value is S45C steel coated with hard chrome 998.63 VHN, increasing 392.7%. Then the heat treatment process experienced a decrease in the hardness value, 528.90 VHN, with a percentage of 88.81%. The results of the microstructure observation showed that the hard chrome layer that had been heated treated showed even cracks in the hard chrome layer.

Different types of electrolytic plasma treatment have been discussed to show the capabilities of the process for improving surface properties of different metals. It is found that the treatment is less time consuming, economical, eco-friendly, and dynamic as compared to the existing heat treatment processes. Its dynamic ability makes it possible to perform carburizing, nitriding, coating, cleaning, polishing, and hardening operations in the same experimental setup with little modification.

Simulation Results

Tons of numerical simulation results are obtained by numerical simulation of casting and heat treatment process. However, these results are not utilized sufficiently, most are wasted. The aim, to predict defects of castings, such as shrinkage, hot tearing, deformation and etc, need further processing of the simulated results. Therefore, the criteria should be established on the processing of the directly simulated results. What kind of more results can be acquired from these calculated data? This is an interesting question. In this paper, schematic analysis is carried out for further processing of results, result mining (RM) is proposed and its meaning is explained. Meanwhile, some case studies are presented.
