Experiments for Hot Mold Shell with Isolated Hot spot by Local Water Quenching in Investment Casting;

Compound water quenching techniques based on computer simulation applied to the heat-treatment of large plastic mould steel block instead of traditional water-oil quenching process were presented,corresponding production equipment and controlling process were developed and applied in industrial practices successfully.

Effects of water quenching on properties of pyrrhotite in calcines of Huangjingdong concentrates are examined using TG-DTA techniques.

Draining glass melt by water quench has become a key technology to cold repair .

The new technology removing the converter residue by water quench has shown distinctive and remarkble advantages of safety, high-speed,economy,application,environment protection and energy saving.

Effect of water quench process on tensile properties of microalloyed dual phase(DP) steel was investigated.

The experimental results showed that under the conditions with the ratio of the water-quenched slag and rectorite of 1∶1,the amount of the additive(IS) of 10%,the amount of 50% water,and the roasting temperature of 400 ℃,the spallation loss ratio of granulated composite material prepared was 0.

Factors affecting flotation of water-quenched slag from a copper smelting plant in Hubei province,such as grinding fineness,pulp density,pH value and the reagent system,were studied.

The optimum conditions for flotation of the water-quenched slag are as follows: natural pH,Na2S 800 g/t,mixed collecting agent 240 g/t,flotation time 6 min,percent of 74 μm particles 95% and solid content 30%.
