RAID Data Distribution Optimization Based on Stripe Unit Heat;

The research of detecting the operatiog states of mechanical. system based on heat flux density;

A numerical method,based on single temperature sensor,constant heat flux assumed and arbitrary number future time steps,was employed to determine the heat flux during rapid cooling on high temperature surface with multiply immersed impinging water jets.

The meshing requirement of finite element model being considered,the storing technique and the calculating method of heat flux are expatiated.

It has been applied to the quantitative analysis of the relationships between the heat flow strength and the thicknesses of hearth wall and slag skull.

It indicates that the former two make both cold and thermal strength decreasigng,while simple substance(C) improves the thermal property of coke for both simple and blending coal.

Through the test analysis carried out for quality of coke and coal of 6 m coke Oven,the influencing factor of thermal strength was discussed,the results show that the type of coke oven,the mode of coke extinguishing,time of coking and granularity of coal are the important factors influencing the thermal property of coke.

The contradiction between constantly pursuing higher coke thermal strength and shortage of coking coal resources has been aggravated, directly threatening the sustainable development and survival of blast furnace technology.
