would u like to know the development trend of steel industry on Chinafirebrick?

ChangXing Refractory is a Chinese leading refractory and oil fracturing proppant manufacturer & supplier with a wide range industries in high temperature.The volume of refractories consumed is projected to rise in the USA, Western Europe, and Japan following an extended period of decline, as economic conditions strengthen in these areas and output of ferrous metals and other refractories-using products rebounds. Output gains in these areas are more likely to result in higher refractories demand because the manufacturing techniques used are already so efficient that it will be much difficult to reduce refractories consumption on a per unit output basis than in less developed countries. Due to their greater use of more costly, high-quality products, the US, Western Europe, and Japan will account for a larger share of the world refractories market in dollar terms in 2020 than they will in tonnage.

The world average consumption of refractories per tonne crude steel was 15 kg/t in 2014, while China‘s average was 20 kg/t. The growing demand for refractories in the Asia-Pacific region is the major driving factor of the market. Twenty years ago, glass consumed 11–13 kg/t of refractories, a figure that has dropped to 4,5–5,5 kg/t today. Steel, on the other hand, has reduced consumption from 30 kg/t in 1980 to 10 kg/t today. Strong growth in emerging markets is the main driving force for the refractories market. In addition, high demand from the glass industry is also expected.
Globally glass industry consumes 0,75–1 Mt/a of refractories, far less than steel. The demand for higher-performance refractories such as magnesia-zircon is increasing. Over 95 % of refractories used in the glass industry are shaped. Monolithics are used in combination with shapes. Environmental concerns prove to be the major restraint for the refractories market. Moreover, because of moderation in raw material costs and refractories prices, growth is restricted.
Lastly, the report is divided by geography – North America, Europe, Asia-Pacific (APAC), South America and Middle-East and Africa (MEA); where in the market share of each region is analyzed and estimates are provided for the next 6 years.Chinafirebrick provides refractory products, calcium silicate products, castable & mortar,fire brick, ladle & tundish nozzle, ceramic fiber with high quality for you.

Open Egyptian Refractory Market with Our Best Sell Product -- Silica Ramming Mass

As per invitation of Egyptian client, our sales manager and engineer went to Egypt on 4th December, 2015, and stay there for 2 weeks. Our client's steel plant is located in Giza city, about 1 hour far from Cairo. Out of space limit, our clients are using 3T induction furnaces now. They built the CCM in October and when our colleagues arrived there, the working condition was still very bad. Considering the heat consumption is very heavy when transporting melting steel from induction furnace to ladle and tundish, temperature of output melting steel should be as high as 1720-1740℃. Sometimes the CCM didn’t work well, keeping melting steel temperature more than 2 hours was very frequent.?

This client bought 24 tons of our silica ramming mass in November. This product is our best sell during the past year 2015, which is mainly designed for induction furnace. When we helped the client do lining for their induction furnace, we could only make the lining thickness as thin as 80/110/200mm. Under this hard condition, our silica ramming mass successfully reached 15 heats. Furthermore, this product is also widely used for building lining of tundish and ladle. If any interests, please don’t hesitate to contact us. Our professional team will give you more details.

Reasons of Why Furnace Built with Changxing Refractory Silica Ramming Mass can Get a Long Using Life

Based on our 30 years experience of medium frequency induction furnace ramming, we find that furnace lining materials quality plays an important role in prolonging furnace using life. It has the following aspects to be concerned.

Firstly, the lining materials should have good character.

1. High bulk density stability and high refractoriness under load, not easy to be melt or soften could make materials not easy to lose strength, appear crack and collapse.

2. Its high thermal shock resistance, good cold and high temperature crush strength could protect furnace wall from cracking and spalling well and could resist to steel liquid slag corrosion.

Secondly, the composition of the refractory material should be strictly controlled.

1. The materials impurities could form low melting point compound under high temperature, which will greatly reduces the materials’ refractoriness, meanwhile, the service life of crucible will greatly reduced. 2. For this lining materials, should have following standard: (SiO2):96.0% or higher; (Al2O3) 0.5% or less; (Fe2O3) 0.5% or less; (TiO2) 0.05% or less; (H2O) 0.5% or less. Thirdly, refractory material particle size ratio is the key element. 1. Reasonable ratio of particle size, can be easily formed high density refractory layer for the furnace, which will avoid in defects during using process.

2. Generally it has 3 types: Coarse, medium and fine. Ratio as bellow: 3.35 mm to 5 mm: 17%; 0.85 mm to 1.70 mm: 33%; 1.70 mm to 0.85 mm: 20%, 0.1 mm below: 33%.

How to Make Tundish Nozzle and Well Block Match with Tundish Lining

When choosing silica ramming mass as tundish lining, the expected service life could be 36-60 hours, but the service lives of tundish nozzle well block are not as long, in this case, how to ensure continuous casting? Here are two options:

1. Using normal sizing nozzle and well block. The service life for normal sizing nozzle and well block is only 8-10 hours, under this condition, we need to change the nozzle and well block every 8-10 hours, which is very time and energy consuming and affect continuous casting to a certain extent.

2. Using exchangeable nozzle and well block. The service life of upper exchangeable nozzle and well block is 24-30 hours, which gives longer continuous casting time, we only need to change the lower nozzle, of course every coin has two sides, under this condition, a set of exchanging mechanism is needed, the cost will be comparatively higher.

Users can choose either of those two options according to practical needs.
There are some essential differences between graphite carburant and coal quality carburant:
First: The raw material of those two carburant is different. Graphite carburant is made from filtered natural graphite, and coal quality carburant is produced from burning anthracite.
Second: They have different features. Graphite carburant has features of low sulfur, low nitrogen phosphorus, high temperature resistance and good electrical conductivity etc., which are not available for coal quality carburant.
Third: They have different absorptivities. Absorptivity of graphite carburant is more than 90%, and that’s why it can meet the using requirement even its fixed carbon is low (about 75%).
Forth: Graphite carburant and coal quality carburant have quite different prices. Even the price of graphite recarburant is a little higher than that of coal quality carburant, its comprehensive cost is much lower.

Changxing Refractory has all the refractory products mentioned above, if you need any of them, feel free to email us or call us!
