Description for Castable

Castable materials should be match mixed with one or multiple liquid uniformly when use. Castable refractory material has stronger liquidity and plasticity.

This refractory material castable has numerous in varieties, of which main products include low cement, ultra low cement and non-cement castable. Combine resource condition and choose and use high quality raw materials and special filler to improve the basic composition, adopt fiber to strengthen castables and self-liquid refractory and use all kinds of addition agent to improve refractory material castable properties. Besides, develop specific castable used for iron tap channel and molten steel ladle lining and special function castable with fuction of wear resistance, acid resistant, alkali-resisting, high-strength heat insulation and high-strength thermal conductivity.

Application of Castable Refractory

Castable material is mainly used in Metallurgical industry kiln, Petroleum, chemical industry, building materials, electrical and mechanical industrial kiln and Thermal equipment.

This refractory materials are wildly used and produced to build all kinds of heating furnace lings.

Some high quality variety also can be used for steel-melting furnace. Such as aluminate cement refractory material castable can be widely used for thermal equipments of heating furnace and other furnaces without slag and acid and alkali erosion.

Use castables that made of high quality granula and powdery which combined low calcium and purity high alumina cement with high alumina content and well sintered for the position of pouring lining, molten steel ladle, furnace stack and iron runner which is bearing the erosion of high temperature, molten iron, molten steel and slag.

Phosphate refractory castable is not only used widely in heating furnace and soaking pit, but also can be used in coke oven and cement kiln. Use high quality phosphate castable to repair the position which directly touched by slag and molten metal in the metallurgical furnace. It can also to protect the position that works in the common temperature but bears strong friction erosion.

Castable Refractory Recipe

Rongsheng Refractory Factory has been manufacturing unshaped refractory material for more than 20 years. We have many experiences to make the BEST refractory mortar castable according to our own castable refractory recipe. By volume, it is 3:3:4 for cement:perlite:silica sand, which is mixed together thoroughly, then combined with 4 parts fireclay. The dry ingredients are then moistened to the texture of “stiff cookie dough,” packed into a form, and allowed to dry thoroughly before bake-out. High castable refractory density make the good thermal shock resistacne for furnace lining application.
