Information
Neutral ramming mass manufacturers tell you that the choice of ramming material for the lining of the intermediate frequency furnace depends on the atmosphere in the furnace, because the lining atmosphere of the intermediate frequency furnace is divided into neutral, acidic, alkaline and composite, and there are core induction and coreless induction. Furnace division.
In general, the acid furnace lining material is made of high-purity microcrystalline quartz sand and powder, and the dry vibrating material mixed with high-temperature sintering agent and mineralizer is added. During the production process, the particle size should be strictly controlled, and the amount of sintering agent added should be controlled during construction. In order to ensure a dense furnace lining can be obtained by knotting. The manufacturer of Neutral ramming mass tells you that there are not too many furnaces with acid lining, the ramming material for acid lining is not used frequently, and the number of replacements is frequent, so the dosage is relatively large.
The neutral furnace lining material is a dry kneaded material mixed with corundum sand, powder, aluminum-magnesium spinel powder and sintering agent. The manufacturer of Neutral ramming mass tells you that this kind of ramming material has strong compactness, good thermal shock stability, and evenly knotted furnace lining.
Neutral ramming mass manufacturers tell you that if it is an alkaline furnace lining, it is necessary to choose magnesium dry ramming materials with good thermal shock stability, volume stability and high high temperature strength, because the backing should be kept loose during use. Floor. Generally, there are many types of coreless furnaces for furnace linings in alkaline atmosphere. The magnesium ramming material has a high bulk density, and the furnace lining has a uniform heating speed. There are also induction stoves with cores, but not many.
According to the situation of use, there are more alkaline furnace linings in recent years, and most of them are coreless induction furnaces. Neutral ramming mass manufacturers tell you that the magnesium dry ramming materials used in furnace linings have also changed to varying degrees. In recent years, more aluminum-magnesium ramming materials have been used, because the price of magnesia has skyrocketed as a factor, but the most important thing is The aluminum-magnesium ramming material has good thermal shock stability and is suitable for intermittent shutdown and temperature fluctuation. And another feature is that because the basic furnace lining is a steel shell furnace, the aluminum-magnesium ramming material heats up quickly and saves electricity.
Neutral ramming mass manufacturers tell you that the quality of the aluminum-magnesium ramming material is different according to the requirements of the heat used, and the price is relatively high if the heat is more than 100 times. , Of course, the quality of the aluminum-magnesium ramming material is determined according to the heat required by the user.
