Intermediate frequency furnace ramming material

Intermediate frequency furnace ramming material has many kinds of way, sometimes called dry ramming material vibration of intermediate frequency furnace and medium frequency furnace lining castablematerials, also known as intermediate frequency furnace refractorymaterial, intermediate frequency furnace, it in fact many properties are the same. Ramming material according to their chemical properties can be divided into acidic ramming ramming, neutral, alkaline ramming of intermediate frequency furnace. Tianjin intermediate frequency furnace ramming material and chemical properties of different decision it contains raw materials of different. Ramming material is the main raw material with high purity quartz, fused silica based ramming acidic medium frequency furnace, sintering agent during the composite to composite additive as the main material; and for neutral knotting material is selected to alumina, high alumina material as the main rawcastablematerial, the neutral knotting material sintering agent in composite additive for sintering agent for alkaline; knotting materials and
their different uses high purity fused corundum, high purity fused magnesia, high purity spinel as main raw materials, with the composite additive for sintering agent. Tianjin intermediate frequency furnace ramming material whether choice even in acidic or alkaline, neutral, to varying degrees have been widely applied to intermediate frequency coreless furnace, core induction furnace. Tianjin intermediate frequency furnace ramming material used for melting of cast iron, ductile iron, forging cast iron, vermicular cast iron and cast iron alloy, carbon steel, alloy steel, the melting of high manganese steel, tool steel, heat-resistant steel, stainless steel, aluminum and its alloy melting, melting of copper, brass, copper nickel alloy and bronze copper alloy etc.. Ramming material refers to the use of ramming (human or machine) method of
construction, and hardened in the heating effect of higher than normal temperatures unshapedrefractory.

IF furnace ramming using errors

Xinmi Changxin Refractory help you interpret frequency furnace ramming material errors, IF furnace ramming many people use when there are errors. For instance, some customers think IF furnace ramming such as quartz sand fight the charge should be done with white quartz sandcastablelike material, there are considered to be more detailed the better, some say as long as the powder not others. These are the right frequency furnace ramming caused understand. Followed by some because of the fines that the furnace is good, it has been the use of fine material, but do not want to use a relatively coarse material. This is a misunderstanding.
Currently, the quartz sand in the end in what material is good? Changxin IF furnace ramming learned the most important need to look at several factors, one is the silicon content, which is the silica content, the higher the better refractoriness another, why are a lot of old customers are willing to adopt the red quartz sand it? Because red quartz sand high refractoriness, there is in addition to iron, at the time of entering into the mechanical quartzcastableiron easily processed, so the production of intermediate frequency furnace ramming sure when iron, or likely to cause wear oven phenomenon. As the ratio of quartz sand grains, the more detailed the better or the thicker the better. This should be a concrete analysis of specific issues. Also a ton of furnace, the thickness of the particle can be, as long as can be with a reasonable proportion. The main problem is a habit. As the saying goes: one-third of seven material use.
Whether even the best materials, if you hit a bad stove ovens, furnaces used in the same age is not high. Therefore, we use the time, Changxin IF furnace ramming what you suitable manufacturers, welcome to come to counseling. “http://www.yilongrefractory.com”
