COPPER MOULD ALLOYS

The copper alloys chosen for the moulds must maintain their physical properties at the operating temperatures of the continuous casting process.

The temperature gradation from the inner wall of the mould to the outside face of the mould can cause serious distortion problems, and Metallurgical Copper Mould Tube is imperative that the correct alloy is chosen for the various operating conditions.

Phosphorus de-oxidised copper

This alloy has been proven to be excellent for the manufacture of moulds in the continuous casting of billets. The main composition of this alloy are Cu +Ag 99.90min, P0.0015 / 0.040.

Copper -Silver alloy

The addition of a small amount of silver, whilst not increasing the melting point of copper, does increase the recrystallisation temperature by almost 100℃, and also helps to give better thermal conductivity at the operating temperatures.

This alloy is normally used in moulds for the continuous casting of blooms and slabs .In this case, the moulds are much thicker than in the billet moulds, and the moulds temperature can be higher. The main composition of this alloy are Cu+Ag99.90 min. Ag 0.08 / 0.12 O 0.004 / 0.012.

Copper Mould Tube supplier

The continuous casting of molten steel into billets, blooms and slab products, has been highly refined over the years into an extremely sophisticated system. The continuous casting process is expected to produce metallurgically sound products at the lower possible cost, and this is being achieved in many steelworks throughout the world.

Copper moulds have played an important role in the development of the continuous casting process. Their funcition is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification.

The mould must exhibit excellent thermal conductivity, be resistant for thermal erosion ,and be resistant to distortion from thermal stress. So far only copper and a few copper alloys meet the above conditions, both economically and technically.

Mould cooling jacket supplier SOLIDIFICATION

The rate of solidification in the continuous casting process dictates the speed of production. The molten steel, which is in contact with the inner faces of the copper mould, starts to sllidify as rapidly as the heat is extracted, forming a shell. The shell increases in thickness as more heat is extracted, and eventually total solidfication is achieved. the process is similar to the solidification of ingots in ingot moulds. In continuous casting, the whole process is speeded up, with the aim to produce and homogeneous shell growth. Consequently, the mould is an important part of the continuous casting process, and the manufactured quality of the mould plays and important role in their length of life.

INNER SURFACE COATINGS

Over the years, Metallurgists and Engineers have been working together to develop better continuous casting moulds. The steel companies require a more economical mould which will give a longer service life. Surface coating of the inner walls of the mould has given the best results to date. Coatings available are Chromium and Nickel plating. Also, a combination of the two give good results on slab casting.

Ceramic lined pipe is made through the self-propagating high-temperature synthesis (SHS) technique.

Self-propagating High-temperature Synthetic process

Self-propagating high-temperature synthesis (SHS) is used to describe a process in which the initial reagents (usual powders), when ignited, spontaneously transforms into products due to the exothermic heat of reaction.

The combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features like abrasion resistant, heat resistant, and corrosion-resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry, etc. It has many advantages over steel pipes, cast stone pipes, and steel-plastic compound pipes.

Usage of Ceramic Lined pipe

The ceramic-lined pipe transportation has been widely used in the industries of electric power, metallurgy, coal, petroleum, chemical engineering, building materials, mechanism, and so on.

The ceramic lined elbow throughout the power, metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries, and high-speed development. When lining the wear-resistant ceramic elbow to deliver high grinding material (such as ash, coal, ore powder, etc.), there is a lining of wear-resistant ceramic elbow wear fast, especially the elbow Wear faster. When lining a ceramic-lined elbow to deliver a highly corrosive gas, liquid or solid, there is a problem that the lined wear-resistant ceramic elbow is corroded and is quickly damaged.

There is a problem that it is expensive to use a heat-resistant steel pipe when the material having a higher temperature is conveyed in the lining of the wear-resistant ceramic elbow. After lining the wear-resistant ceramic elbow, these problems are solved.

The ceramic lined elbow is widely used in wear and tear of mine filling material, ore powder and tailings transportation, coal-fired power plant powder, smelting, ash and other things lined with wear-resistant ceramic elbow are also very appropriate.

The ceramic lined pipe, Elbows, Reducer, Tees, and others manufactured in our factory have been used in over 200 thermal power plants, more than 50 mines, and the industries of coal, building materials, mechanism, petroleum, and so on.

Hoop strength is the resistance against radial pressure. The strength of the ceramic-lined steel composite pipe is 300 to 500MPa.

Features and Advantages of ceramic lined pipe

Ceramic Liner pipe is a high technology production technology-self-fuel high-temperature clutch synthesis method.

1). High Abrasion Resistant:

Vickers hardness of the corundum lining is HV1100 to1500, as high as that of tungsten-cobalt hard alloys, and the abrasion resistance is 20 times as carbon steel pipes. The composite ceramic-lined steel elbow was used in a mining plant for about fifty thousand hours. The general service life of a common steel elbow is about 700 hours.

2). Corrosion Resistant:

Corundum is a neutral material and is acid-proof and fouling-free.

3). Heat Resistant:

Ceramic lined composite steel pipes can work under circumstances of -50 to 800 Celsius degree.

4). Lower Weight and Convenient Installation:

The ceramic-lined steel pipes are lighter than alloy pipes, cast iron pipes, and cast stone pipes and can be welded or connected through flanges, which reduces the expense of transportation and makes the pipes easier to install.

For the pipes with the same sizes, types, and lengths, the weight of the ceramic pipe is about 1/2 of the wearable cast alloy steel pipe’s, while the cost has reduced 10%~20% per meter.

The weight of ceramic-lined steel pipe is about 1/3 of the cast stone bent pipes, 1/2 of the cast stone straight pipes.

Ceramic (Corundum: a-Al2O3) lined abrasion resistant straight pipe and fittings are lined with highly abrasion-resistant ceramic by SHS ——-Self-propagating High-temperature Synthetic process.

• The ceramic-lined steel composite pipe can be joined by welding the steel pipe layer.
• Ceramic-lined pipes can take place of expensive stainless steel, titanium, nickel, cast stone, or alloy pipes.
• Extended service life can also reduce maintenance costs.

Self-Propagating Ceramic Pipe

Self-propagating ceramic steel pipes create a new generation of abrasion and corrosion-resistant engineering pipelines.

The self-propagating ceramic steel pipe has very good wear resistance, Excellent corrosion resistance, and Excellent thermal resistance performance.

SHS-self-propagating ceramic steel pipe and elbow create a new generation of abrasion and corrosion-resistant engineering pipeline. The composite pipe is composed of three layers: ceramic, intermediate, and steel layers.

The ceramic layer is formed by molten alumina at a temperature above 2500 degrees. The molten alumina produced from the reaction Fe2O3+2Al=2Fe+Al2O3 spreads on the inside wall of the steel pipe under the influence of a centrifugal force, then solidifies, so the ceramic layer has high density and smooth surface and bonds to the steel pipe.

Applicable Industries:

1. The pipe needs excellent wear resistance property: Power plant, Mining, Sea Port, Coal Plant, And pipe for transporting the powder, slurry, sand, etc.
2. Coal washing plant, pipe for transporting coal and other material.
3. Pipe for transporting the melted aluminum.
