Cold crushing strength and high temperature crushing strength of refractory brick

图片
Cold crushing strength Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature. The cold crushing strength of pressure-resistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is better. The high crushing strength indicates that the processed quality is good, structure is uniform, and well sintered. High temperature crushing strength High-temperature crushing strength is the refractory products under the specified high temperature conditions, the unit area can withstand without damage. The high temperature crushing strength of refractory products determines the use scope, which is an important basis for the use of refractory materials . High temperature crushing strength indexes are also meaningful to unshaped refractories, especially refractory castables and fire-resistant plast...

Property and application of refractory ramming mass

The refractory and the erosion resistance of the refractory can be obtained by selecting the high quality refractory material and having the proper proportion and strong tamping, Compared with refractory castable and plastic, it has high stability and corrosion resistance at high temperature. However, the service life depends largely on the pre sintering of the used or the amount of sintering used for the first time. If the heating surface is sintered as a whole and cracked and not separated from the bottom, the service life can be improved. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc. Article Source: Property and application of refractory ramming mass Company name: Wanhao Refractory Email:sales100@wanhaorefractory.com Website: http://www.wanhaorefractory.com/           ...

The Characteristics of Refractory Industry

First, refractory production continued to decline. The refractory production in 2016 continued the downward trend in 2015, a decrease of 8.56%. The main reason for the decline in refractory production is the rapid and drastic reduction in the market demand for refractory materials for infrastructure projects.  From the output of different refractory products, silicon brick production decreased the most, as high as 37.59%; high alumina products and clay products were down more than 10%. Second, the export trade situation is grim. In 2016, the total export volume of refractory raw materials and products fell to its lowest level in the past five years, only 2.565 billion USD, down 11.62%, and a decrease of 765 million USD from the 3.33 billion USD, the highest point in 2014, down 22.97%. Third, the imports of refractory raw materials have increased. In 2016, the total imports amount of refractory raw materials and products is 324,900 tons, an incre...
