STUDY solidification and mechanical properties of refractory concrete MIKROKREMNEZEMISTOY GEL BASED ON DIFFERENT conjunction with cement

Cementless refractory concretes based mikrokremnezemistoy gel ligaments have attractive properties, in particular good flow at very small amount of water and the ability to withstand extremely high temperatures after drying. Although their strength in a wet state is less than the low-cement concrete, it can be used without cracking. After drying at 110 ° C, the strength of such concrete increases significantly. The article presents the results of research samorastekaemosti refractory concrete based on white fused alumina, as well as their strength in cold and hot state at temperatures up to 1500 ° C. Porosity measurement showed that it corresponds to the volume of water used in the manufacture of concrete.

The technology and equipment flow control subsystem metal casting ladle - tundish for long continuous casting machines (CCM). Designs of elements of the device to protect the metal stream in the casting on the CCM. The design of the device to protect the metal stream during pouring for continuous casting machine precludes the passage of air into the jet of metal in the casting and provides a rational parameters feeding argon into the annular recess refractory tube, which improves the quality of the cast metal. All this allows us to ensure the stability of the casting process and improve the quality of the cast metals. Key words: continuous casting machine, the intermediate ladle refractories, manipulator, argon.
