Features: Environmental friendly non-hydrous gun mud uses the mixed liquid formed by resin binder and special materials of the company as composite binder.It has moderate sintering speed,no damp mud,excellent high temperature erosion resistance and erosion resistance.It produces less smoke and less irritating smell in the process of use,which reduces the physical injury to workers and is environmentally friendly and pollution-free, which is conducive to improving the working environment in front of the furnace.
In order to maintain the taphole well,according to the working conditions,it is generally required that the taphole should have the following properties:
① It has good workability,can be easily pushed out from mud gun,and has high filling density;
② The opening performance is good,and the drill bit of the opening machine is easy to drill in;
③The erosion and erosion of high temperature resistant iron;
④The volume stability is good,that is,the volume changes little at high temperature;
⑤ High fire resistance,>1580 ℃;
6. It has a certain plasticity at room temperature
