Today is really awful.

Took a flight to downsouth, waited in a noisy and dusty enviroment for couple of hours, and executed carefully step by step, the third trial was failed totally. It meant that the last opportunity involving the self-flow refractory castables for the blast furnance constructing was gone. In my personal opinion(plus my colleage's), there are two major points causing the fail : one is the viscosity of mortar and another is the power of pumping mechine. At this moment, I don't want to waste time to give the details. I may discuss in my next essay, may I?! If we can not overcome or try to fulfill the power of pumping mechine, we may reduce the viscosity. In one word, we may not know well the key technique of self-flow refractory castable. Alas, fail is fail, a loser can not defend or debate for himself. I do not know that mey we get any chance again to modify this fail, but I am sure that there will be a strom in office tomorrow no doult. I have nothing to explain, do not want to give a word for controverting, get ready to prepare for the worst, and just tell the situation frankly. Anyway, the business is totally screwed out by the R&D ourself.
