In the present work,on the basis of calculation of liquid flux channel pressure in meniscus for slab continuous casting mold,a new mechanism of the liquid flux consumption was proposed by analyzing the deformation behavior of initial solidifying shell during the mold oscillation cycle as high casting speed 2.

The thesis analyses the defeclts of the slagging material in converter blowing and introduces the components of monocalcium ferrite ball as well as its producing technology,especially the feasibility of using monocalcium ferrite instead of lime,fluorite and iron scale in converter blowing.

Experiences in decreasing the raw material consumption in the production of chloroacetic acid;

Several aspects of this two processes were compared respectively, such as the material consumption, cost estimation, process properties, economic benefits and social effects, etc.

This article analyzes the present conditions of fuel consumption of local vehicles in the view of existing problems,and put forward some measures for economizing fuel with practical experience.

Fuel consumption for a series of lunar probe engines with different thrust weight ratios and specific impulses is simulated based on above two techniques.
