Ceramic Coated Oxygen Lance Pipe

Minco Ceramic Coated Pipe (CCP), is used for oxygen injection into steel mill electric arc furnaces, AOD'S and ladles. Minco CCP applications include powder injections, tap hole cleaning and opening nozzles in ladles, tundishes and EBT's.
Minco CCP was developed to increase lance life beyond conventional calorized or black pipe. Due to MPI's innovative methods of refractory deposition for interior and exterior coatings, Minco CCP provides unequaled lance life at lower cost.
A special ceramic coating has been developed for copper smelter applications. Minco CCP is used to inject gas into the Submerged Electric Furnaces.  CCP provides a much longer life in the high temperature furnace environment than previously used stainless steel pipe. Using CCP to inject gas in the Submerged Electric Furnace reduces costs and down time for smelter production.

Various Uses of Minco CCP
Applications in addition to cutting scrap, raising bath temperatures and decarburizing include the following:
opening nozzles in tundishes and ladles
injecting carbon and other powders into the electric furnace and ladle
opening the iron notch of a blast furnace
removing slag adhering to the tapping notch of converters and various kinds of ladles
injecting argon into ladles
raising temperature when steel is treated with KR, DH, and RH methods
injecting argon and oxygen into the AOD
injecting flux for degassing in aluminum melting furnaces

Ceramic lined steel pipe

Introduction:

It is the ideal wearable and corrosion resistant engineering pipeline, with wear resistance 15 times higher than common steel pipe, smooth inner surface, and favorable liquor resistance. The lining clad layer consists mainly of molten alumina withing a hardness of 1500-1800 vickers throughout the intire material. It is mainly used in electric power, metallurgy, mining, coal, and chemical industry when conveying grindable granule and corrosives media, sucha as sandstone, coal fines, clinker, alumina liquid,etc.

Features:

• High abrasion resistant: Vickers hardness of the corundum lining is HV1100 to1500, as high as that of tungste-cobalthard alloys, and the abrasion resistance is 20 times as carbon steel pipes. Its rigidity is the highest among all oxides.
• Corrosion resistant: Corundum is a neutral material, and is ac-proof and foulingfree.
• Heat resistant: The pipe can work under circumstances of -50 to 800 degrees Celsius.
• Convenient installation: It is much lighter than any other types of composite pipes, and can be welded or connected through flanges.
• Cost effective: Ceramic -lined composite steel pipe can take the place of expensive stainless steel, titanium, nickel, cast stone or alloy pipes. Extended service life can also reduce maintenance cost.

Application:
The ceramic-lined steel pipes have numerous exceptional properties including good resistance to abrasion, heat, mechanical and thermal shocks. The pipes are easy to weld and fixing. They are very suitable for the transport of abrasive materials and thus can replace cast ceramic pipes, alloy pipes, and resin-lined steel pipes. They have a wide variety of application in mining, power plants, water conservation and metallurgical, coal, petroleum, and building material industries.

  

Abrasion Resistant Ash and Slurry Conveying Pipeline

Abrasion Resistant Ash and Slurry Conveying Pipeline

Recently, excellent abrasion resistance is required for the pipes used in the slurry transporting systems, for example, which transport the coal ash in pulverized coal firing boilers. We have developed abrasion resistant pipe for transportation of slurries and ash named ceramic lined steel pipes which provide significantly longer life .

1. The Manufacturing Process of Ceramic Lined Steel Pipe and Elbow:   

  

SHS（Self-propagating High-temperature Synthetic process）ceramic lined steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline.The composite steel pipe is composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500 degree. 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.

Abrasion Resistant Ceramic Lined Pipes have been uniformly produced by a thermite reaction induced under the influence of a centrifugal force (“Centrifugal Thermite Process”) without any high-temperature furnace facilities. The characteristic feature of the present process for forming uniform ceramic layers is in its reaction propagation as well as the reaction heat and centrifugal force. It is very important in improving the quality of the ceramic lined pipes to find the proper conditions of the reactant and centrifugal force; the former mainly determines the produced ceramic layer quality and the latter the achievement of layer separation and the mechanical properties of the pipes. Ceramic lined tube has great resistance against corrosion, abrasion and thermal shock.

2. Features and Advantages:

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 thousands hours. The general service life of 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 pipe 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 length, the weight of 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 pipe's, 1/2 of the cast stone straight pipe's.

5). Lower Cost :

Ceramic lined pipes can take place of expensive stainless steel, titanium, nickel, cast stone or alloy pipes. Extended service life can also reduce maintenance cost.

Ceramic tile lined steel pipe

Brief Introduction:
Ceramic tile lined steel pipe have very uniform coating of a specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. Ceramics with a very low friction factor at low impingement angles can decrease the abrasion of materials maximally. Besides, its low density can makes it an easy-going character to carry and install. Depends on different working environment, direct adherence or bolt fastening could be applied for construction.

Feature

• Strongest abrasion resistance.It has the excellent performance of 266 times than Manganese steel, it could be continuously used for more than 10 years.
• very good intensity and hardness but with light weight. Its hardness is HRA80-85, much better than normal stainless steel, its density is half and weight is only 1/3 of pure steel pipe, then it is easier for installation or replacing.
• With firmest sticking .The ceramic tiles could protect industrial components against abrasion and high temperature of above 1000°C, and as the ceramic is the inorganic material, not easy for oxidation, then it has good corrosion resistance.
•Very smooth inner surface for fluent material transfer.

Application
Its low density makes it easy to carry and install. Furthermore, its diamond-like hardness, fine grain structure and superior mechanical strength are the unique features that make it a wide range of demanding applications, such as coal preparation, power generation, iron and steelmaking, cement, asphalt, dredging, mining and mineral processing, oil and gas drilling etc.

Ceramic tile lined Chute

Alumina ceramic lined chute for material convey systerm equipments. which can deal with shock resistant and abrasion resistant as well as hight tempetature. In the cement or coal fire station, the out let of the mill chute suffer from heavy abrasion, we use the curved ceramic tile to lined into the chute with special adhesive. The service life time can be 7 to 8 years.
