Drainage sand recipe, drainage sand prices, Tianjian Brilliance

With the development of continuous casting technology, the original ceramic stopper rod sliding gate has been replaced + drainage sand. As people of steel quality requirements continue to increase, the need for automatic start of casting ladle. If you can not automatically open water, through the lance a boil, assisted drainage, which will lead to a significant number of open pouring molten steel, causing secondary oxidation, affecting steel quality and increase the casting cost, threatening the safety equipment and operating personnel. I plant the production of chromite sand drainage material is South Africa's imports of high-quality chromite based materials, by adding an appropriate amount of lubricants, sintering aids, such as reducing agent from a system, as the bottom of the ladle nozzle filling material, on the one hand requirements can be sintered at a lower temperature, in addition, since the ratio of the major chrome sand, can effectively avoid joining steel drainage sand float accident; on the other hand meet the requirements of the steel surface at a high temperature and long sintering refining state can not be too thick, Otherwise, automatic open casting rate response, thus affecting the normal smelting operation.
