What are the common misunderstandings of Neutral ramming mass

Neutral ramming mass has a wide range of applications, whether it is cast iron, cast steel, cast copper, ductile iron, ironworks, etc., Neutral ramming mass will be used.

There are many misunderstandings in the use of Neutral ramming mass. Some people think that white quartz sand should be used as the raw material when choosing quartz sand as the charge. These are formed by ignorance of Neutral ramming mass. Some people feel that the furnace age is good after using fine materials, so they always choose fine materials, rather than using relatively coarse materials. This is a misunderstanding. Now, the main demand for quartz sand raw materials is to examine several factors, one is the content of silicon and the content of silica. Silica must be above 99%, and the higher the refractoriness, the better. As for the proportion of quartz sand particles, the finer the better or the coarser the better. This should be analyzed on a case-by-case basis. No matter how good the information is, if the furnace is not good, the furnace age is not high enough.
Therefore, when you use it, in addition to buying Neutral ramming mass from a suitable manufacturer, you must strictly follow the instructions given by the manufacturer.
