  After the fine powder is introduced into the medium induction furnace, many small voids are filled, which reduces the air permeability of the induction furnace charge and causes bursting. Reason for crack of induction furnace lining material : Calcium aluminosilicate hydrates or gels, which are similar to zeolite type in the traditional medium frequency charge, are seldom formed by the decomposition of hydrates and become exhaust channels before 300 degrees. After 300 degree dehydration, a large amount of water vapor is released and burst. Easy solution to crack of induction furnace lining material : 1. Adopt reasonable drying and heating system to control the maximum vapor pressure inside the medium frequency charge; 2. Explosion proof agent and other anti explosion substances are added to the induction furnace charge to increase the air permeability of the hardened body and reduce the internal vapor pressure of the castable. Wanhao is a manufac...

Refractory materials   generally refers to the degree of fire in the 1580 C or more inorganic non-metallic materials, including natural ore ( refractory raw materials ) and according to a certain purpose and requirements, according to a certain process to produce a variety of products (fire resistance), with a certain degree of high temperature mechanical properties and good volume stability. Refractory materials are steel, nonferrous metals, petrochemical, building materials, machinery, electric power, environmental protection and even national defense and other important basic materials, but also a variety of high temperature industrial furnaces and equipment indispensable support materials. Technological progress of refractory materials plays an important role in the development of high temperature industry. Enterprise organizational structure adjustment, namely to "group" principle, the formation of a number of famous and special products, have complete independent devel...
