Brick manufacturers analyze the factors that lead to the erosion of glass furnace refractory bricks: Glass melting furnaces are constructed from a variety of refractory materials. Different refractory materials used in different parts. Such as: direct contact with the liquid glass parts, the upper space and regenerative parts of the site. Production, due to erosion of these parts of different conditions, refractory erosion are also different. Firebrick erosion directly affects the life of the melting furnace, affecting the glass production, quality and energy consumption. Melting workers to understand the erosion of refractory bricks, no doubt on the production of great significance.
First, the melting furnace refractory bricks under erosion conditions
Furnace refractory bricks under erosion conditions, in general, should be from the temperature conditions, chemical erosion conditions, physical erosion conditions and time conditions to consider. These four conditions in the erosion of refractory bricks can not exist alone, must be a combination of several conditions. Such as brick heating or cooling process, which is the temperature and time of the two conditions, including both the rate of heating or cooling, but also the maximum temperature and the holding time, chemical etching conditions to remove the type and number of etchants, the temperature level, sustained The length of time and the number of times have a great impact; physical erosion conditions as well. Often physical erosion and chemical erosion often coexist. So in the glass melting furnace, the result of these four conditions together determine the rate of firebrick erosion.
The conditions under which the refractory bricks are eroded are the same for different parts of a furnace. The other three conditions are very different, each with its own special law.
