The structural strength of unshaped refractory materials by combining the control, unshaped refractory materials are generally aggregate by combined continuous phase and a discontinuous phase composition of unshaped refractory material, binder, according to their binding mode can be divided into the following several: hydration, chemical bonding, with ceramic bonding, adhesive bonding and the union, unshaped refractory materials for the mechanical construction are castable and gunning down, so always be able to get the stable development is pouring material and gunning material.
Unshaped refractory has the advantages of simple process, short production cycle, saving energy, the overall use of good, strong adaptability, convenient mechanized construction, unshaped refractory materials production is close to firing refractory products in production, unshaped refractory materials industry contributed to the huge change, this also shows that the rapid development of unshaped refractories unshaped refractory materials, the history goes back to ancient times of the original, was pottery age and the Bronze Age pottery, baking for use at the time of kiln and furnace smelting bronze (or crucible) is the use of refractory clay plasticity shaping or rammed into, it can be said that the amorphous refractory material is the original.
