Silicon carbide based refractory materials

Silicon carbide (SiC) is an artificial mineral, refractory raw materials for the silica and coke, 2000 ℃ above the high temperature electric furnace synthesis, silicon carbide refractory is divided into three categories: (1) plus clay and other oxide-bound products; (2 ) Nitride-bonded products; (3) the use of silicon carbide recrystallization, pressure molding self-bonding products. One of the most common application of clay bonding products, China is currently the production and use of this one.

Carbide as a binder of silicon carbide grade products containing SiC87%, refractoriness up to 1800 ℃, load softening point 1620 ℃. The silicon carbide products have some special properties that make it suitable for certain applications such as (1) its thermal conductivity is about 10 times higher than that of conventional refractory materials and is suitable for use as heat-conducting devices such as heat treatment furnaces Cover. Because of its good thermal conductivity, 1200 ℃ below a strong antioxidant, so the life than the metal cover long. According to the same reason, can also be used as heat exchanger components. (2) mechanical strength, good wear resistance, resistance to rapid cooling hot or good, so some of the roller furnace with it for easy to wear roller sets, the cost is lower than the heat-resistant steel. (3) larger than the resistance, can be used as electric resistance of the furnace.

We are mainly producing high alumina brick, high alumina refractory fire bricks, alkali resistant brick, castable, clay brick, insulation brick, light high alumina brick, low creep high alumina brick, high aluminum wear Brick, high aluminum lightweight insulation brick, clay insulation brick, if you have any need contact us anytime.

Global refractory market will reach 42.5 million tons in 2022

Emerging market infrastructure drives the recovery of the steel and cement industry and then drives the?refractory?industry slow growth. It is expected that by 2022, the global refractory market will reach 42.5 million tons. Despite China's economic slowdown, but China as a refractory power consumption, still occupies a pivotal position. Developed countries, such as the United States, Japan and Europe are very different, they use more efficient advanced production technology.

Although the current steel industry is still the main application areas of refractory industry. But the next few years, non-ferrous metals and minerals and minerals will become the mainstay of the refractory industry. Unstable castables and preforms will receive increasing attention due to their high performance and flexibility. Zirconium / zirconia, silicon carbide, ultra-high alumina and other special?refractory materials?will become increasingly popular because of their high performance applications in special fields.

The properties and applications of silicon carbide

On the domestic 34 black silicon carbide production enterprises to investigate statistics, in March China's black silicon carbide business average operating rate of 49%, compared with February increased by 6.58%. Changxing refractory offers many kinds of refractory products for you. Such as fire brick for sale, refractory nozzle ,refractory raw materila and other refractory products. March, Gansu Province, environmental protection efforts to reduce the number of enterprises have been normal production, coupled with the output of Ningxia region has also been restored, so in March China's black silicon carbide production continued to rise. Ningxia area operating rate from 51.89% to 62.81%; Gansu region operating rate from 29.86% to 36.49%.

China's black silicon carbide inventories rose in March, slightly lower downstream purchases, but after entering in April, the downstream inventory is insufficient, coupled with the export market exports will increase, taking into account some of the green silicon carbide production enterprises have Converting black silicon carbide in the plan, it is expected in April China's black silicon carbide production will continue to rise.

Changxing always offer best products and top servic for you all the time. Such as magnesia carbon brick, fire brick, refravtory raw material and other refractory products. Welcome to view our factory anytime.
