Main factors affecting the service life of the refractory bricks

According to the long-term use of refractory bricks and refractory brick life mainly includes the influence of the specific use of the environment, the operating temperature of refractory brick
kiln, the use of the number of fly ash erosion. The principle of damage of refractory brick includes three aspects, the solubility, permeability, cinder of refractory brick erosion, friction. These three processes and ultimately affect the service life of the refractory brick, firebrick damage caused by.

Slag brick permeability leads to uneven texture, when encountered high temperature refractory bricks, due to uneven texture, resulting in heat coefficient is not the same, cracking caused by refractory brick. According to the summary of practical application, start and stop times increase the erosion of furnace firebrick, so the reasonable control of furnace of the open stop times can prolong the service life of refractory bricks.

Effect of fly ash on properties of  refractory brick is relatively large, very permeable brick composition of fly ash is silica, a relatively high calcium oxide, if these two components in coal ash, so the erosion of refractory brick is very large, a reasonable construction of the two components can reduce the erosion of refractory bricks to improve refractory brick service life.

Room temperature compressive strength of refractory materials

Compressive strength refers to the maximum pressure unit of material under normal temperature area can bear, N/mm2 MPa (MPa) said. Room temperature compressive strengthof refractory materials is an important technical property of materials. Although in general the thermo technical equipment Institute of refractories under static load is small, generally not more than 0.1~0.2 N/mm2, top brick is not more than 0.4~0.5 N/mm2, large blast furnace, hot air furnace, open hearth brick regenerator checker brick layer, the maximum load is less than 1 N/mm2. In addition to the improper transport and masonry, make the material by the impact and extrusion and may be damaged, rarely for room temperature compressive strength is low and the destruction of materials. In the current standards are specified compressive strength of refractory products at room temperature not lower than that of 10~15 N/mm2, for advanced refractory product requirements in the 25~30 above N/mm2, is mainly because the cold crushing strength ofrefractory products are the parameters of its organizational structure, especially the sensitive parameters of microstructure. While the material micro structure formation is restricted by material preparation process of various factors, such as raw material characteristics and mixture ratio, particle size and gradation, inter particle binding, molding process and sintering condition, have important effects on Micro structure of materials. Therefore, compressive strength at room temperature is a reliable method for testing the current process status. In addition, through the room temperature compressive strength of materials can be evaluated indirectly the merits of other mechanical properties, such as 2~3 times the normal temperature compressive strength generally refractories is about bending strength is 5~10 times; tensile strength; good wear resistance and impact resistance of all has high tensile strength at room temperature corresponding. Moreover, method for determination of compressive strength at room temperature is simple. Therefore, compressive strength is the routine test and judge the quality of products.

The production principle of the castable

With our current for various material and construction industry in the use of situation,specializing in the production of casting material manufacturers staff told us that, the production of casting material mixer is used mostly for under actuated setting scheme work, in the motor of the mixing drum is used to supply the most positioned below the stirrer used in power supply, the use of the transmission mechanism is connected with the motor of the cycloid reducer to secure direct drive system for electric drive system of fibrillation, the power transmission is the leading domestic advanced level strong.

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 materials, 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 rawmaterial, 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 sandlike 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 quartziron 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”
