Carbon-free and environmentally friendly dry refractory ramming mix/Magnesium ramming mix/no carbon gain in use
Product description:
The new carbon-free environmentally-friendly dry material is a high-quality dry material developed to solve the problem of releasing irritating harmful gases during construction and baking, and increasing carbon and hydrogen in the process of using steel.
Category of Refractory ramming mixes:
Features:
It uses environmentally friendly inorganic salt as binder and sintering agent, and does not contain organic binder. Therefore, it will not release flue gas during construction and baking, and it will not pollute the environment. Because it does not contain organic matter, the lining material does not contain residual carbon. It will not release hydrogen-containing volatiles, so it will not increase the lightness and carbonation of molten steel during use, and can meet the requirements of casting high-grade steel for lining materials. It is a high-quality, environmentally-friendly green refractory new product.
