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.

Specializing in the production of casting material manufacturers staff told us that, when the device enters into the normal working state, this time again will produce castable  refractory materials and need to be mixed objects added to the mixing plate special equipment of the mixer, at this moment together, add water by adding water pump, water is injected into the mixed plate of a certain amount of time water, water and materials are common mixing, evenly stirring, pouring material formation.

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”

The selection of castable should focus on products cost-effective

Now with some heating furnace and increase the number of metallurgical equipment, peopleneed to use in the production process to Tianjin castable such products, which mainly showed granular or powder, widely used in these devices, its mobility is very good. With the improvement of the production technology, superior in quality is more and more secure. In this case, the use of materials with refractory properties in this continuously under a wide range of conditions, how to improve the product purchase need to pay attention to the price is a lot of problems in the process of industrial production, to improve our use of demand.

First of all, the better quality products, must be able to fully guarantee the products we need quality, has good fireproof effect, make our product has very good practical value. We choose
this kind of Tianjin casting material production enterprises need to be very careful, because of the particularity of this kind of  refractories in the composition and use, need to use of the technology is still relatively high, a little mistake may cause problems on the use, especially this kind of product in the production, storage, if not able to pay great attention to the process of transportation and use, it may cause some security hidden danger, the development of the entire production process is negative. So the quality should be put in the first.

Second, product price is very reasonable. At present has the ability to produce this kind of Tianjin casting material manufacturers are also a part of, according to the manufacturers and some of its usage, we can measure how well each manufacturer’s product price and we need to pay the prices in this process, also includes transportation costs, by contrast, choose to create a higher performance price ratio.
