Ladle Submerged Entry Nozzle

Submerged entry nozzle was development in 1960s. At first time, it was produced from quartz. With the development of continuous casting, it can not meet the requirement of high level continuous casting and special steel casting.

With the improvement of the level of casting, especially special steel casting, quartz submerged entry nozzle can not meet requirement of casting life and steel quality. Therefore, aluminum carbon and aluminum carbon-zirconium carbon combined submerged entry nozzles came out. Compared to quartz submerged entry nozzle, this nozzle is of much longer service life. In order to adapt to low carbon steel casting, the inner layer of the ladle nozzle uses special refractory materials like aluminum magnesium, ceramics, etc. For casting aluminum killed steel, nozzle would easy to get block out of caking. Against this condition, both blowing argon in the way of ventilation and using non-carbon-containing and calcium zirconate material have achieved a good result. To solve some emergency working conditions, non-baking submerged entry nozzle was developed. By the methods of designing the trapezoidal submerged nozzle, and mounting impeller in the nozzles, we can make slag floating, in which way blocking can be well prevented.

Changxing refractory provides refractory products, calcium silicate products, castable & mortar, china refractory brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you. Such as high alumina refractory bricks, magnesia carbon brick, clay refractory bricks and other refractory products.

The Belt and Road,Mutually beneficial Win-win with the world

The Belt And Road, refers to economic Belt "silk Road" and "Marine silk Road" of the 21st century. On September 7th, 2013, chairman Xi Jinping delivered an important speech at the university of Kazakhstan Nursultan Nazarbayev, the first time to put forward strengthen policy communication, road unicom, trade flow, currency, hearts are interlinked, work together for economic belt "silk road" of the strategic initiative; On October 3rd, 2013, the chairman Xi Jinping putted forward when delivered an important speech in Indonesia congress explicitly, China is committed to strengthening the construction of connectivity with ASEAN countries, and is willing to work with ASEAN countries develop Marine partnership, mutual construction "Marine silk road" of the 21st century. There have many kinds of refractory products in our factory. Such as fire brick for sale, refractory nozzle,refractory raw material, Magnesia Carbon Brick and other refractory.

The continuous development of Refractory material in China

ChangXing refractory is a Chinese leading refractory and oil fracturing proppant manufacturer & supplier with a wide range industries in high temperature field . From a refractory bricks manufacturing factory, Changxing has become a professional manufacture with various refractory materials and oil fracturing proppant both?in domestic and international market during 30+ years, whose customers covering North America, Middle East, South Asia, Africa, etc.
Many refractory products, in final shape, resemble a typical construction brick. However, there are many different shapes and forms. Some refractory parts are small and may possess a complex and delicate geometry; others are massive and may weigh several tons in the form of precast or fusion cast blocks.
What Are Refractories Made Of?
Refractories are produced from natural and synthetic materials, usually nonmetallic, or combinations of compounds and minerals such as alumina, fireclays, bauxite, chromite, dolomite, magnesite, silicon carbide, zirconia, and others.
What Are Refractories Used For?
In general, refractories are used to build structures subjected to high temperatures, ranging from the simple to sophisticated, e.g. fireplace brick linings to reentry heat shields for the space shuttle. In industry, they are used to line boilers and furnaces of all types--reactors, ladles, stills, kilns--and so forth.
Depending upon the application, refractories must resist chemical attack, withstand molten metal and slag erosion, thermal shock, physical impact, catalytic heat and similar adverse conditions. Since the various ingredients of refractories impart a variety of performance characteristics and properties, many refractories have been developed for specific purposes. It is a tribute to the refractory engineers, scientists and technicians, and plant personnel that more than 5000 brand name products are listed in the latest Product Directory of the Refractories Industry in the United States.
ChangXing has a production line, which is base on oil & gas applied ceramic proppant, and also with 3 factories focusing on all kinds of refractory materials used for iron & steel casting, cement, glass petrochemical and ceramics industries. With abundant sources and professional techniques, we would like to build a reliable and efficient platform for customers all over the world.

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.
