Silicon Metal Description Silicon metal is also called crystalline silicon or industrial silicon. The deoxidation efficiency of silicon metal is very high, and it is often used as the raw material of ferrosilicon alloy. In steelmaking production, silicon metal can increase furnace temperature, increase molten iron fluidity, and improve the toughness and cutting ability of castings. Silicon metal 441 has a higher silicon content. So it can be used as an iron alloy additive in the steelmaking industry. The price of silicon metal 441 is higher than metal silicon metal 553, but the quality is better. Silicon metal grade 441 Application: 1. The main use of silicon metal is as an additive for non-ferrous alloys. 2. Alloying agent for demanding silicon steel. 3. Silicon metal is a good component in aluminum alloys, and most cast aluminum alloys contain silicon.

Material Introduction MACOR® can be considered unique as its composition comprises 55% fluorophlogopite mica and 45% borosilicate glass. Corning’s unique production process results in Macor’s microstructure that is a key to its versatile properties. MACOR® offers a unique combination of properties, unlike any other technical material.It is a white, nonwetting, odorless and non outgassing material that exhibits zero porosity.Extremely machinable, MACOR® offers tight tolerances capabilities,allowing complicated shape design (optimal performances up to +/- 0.013 mm for dimensions, < 0.5 μm for finished surface and up to 0.013 μm for polished surface). MACOR® remains continuously stable at 800 °C, with a maximum peak at 1000 °C under no load, and unlike ductile materials, doesn’t creep or deform. Its coefficient of thermal expansion readily matches most metals and sealing glasses. As an electric insulator, particularly at high temperatures, it is excellent at high voltages and a broad spectrum of frequencies.

welded gabion mesh introduction: Welded Gabion is made of welded wire mesh panel, it is assembled with a spiral- shaped wire to assemble the front and rear panels, the bottom plate and the partition after welding, and is packed together with the mesh cover. All the caged products that are folded and tied are an independent individual. Welded gabion mesh install: Field installation is quick and easy. With diaphrams and stiffeners installed, the gabion may be filled with standard loading equipment. After filling the gabion, a lid is placed on top and secured with spiral binders, lacing wire or "C" rings. Welded Wire Gabions hold their shape better - they don't bulge out when filled. They are easy to handle, which means more work, less labor and higher productivity on the job. welded gabion mesh applications: 1. Retaining wall structures 2.

The corrosion resistance of stainless steel wafer mainly depends on its alloy composition and internal structure, the main role is chromium element. Chromium has high chemical stability, forming a passivation film on the surface of the steel, isolating the metal from the outside world, protecting the steel from oxidation and increasing the corrosion resistance of the steel.

Aluminium Coil Coating Line - Litong Why is it necessary to coated aluminium coil or plastics with an aluminium coating? To prevent corrosion of items as well as aesthetics. The first continuous coil painting line, invented by Joseph Hunter, laid the groundwork for the subsequent development of industrial automation. Smalls says it was a very cost effective way of painting metal. So what are the main equipment and process of aluminum coil coating line? I. Main coating equipment 1. Terminal equipment and aluminum coil coaters. 2. Metal treatment. 3. Primer/topcoat applicator. 4. Air cooling and water quenching; air cooling is used to reduce the strip PMT (peak metal temperature) to about 150-170 degrees Celsius. 5. Process control. 6. Tension straightener; this is where a high degree of control is required and aluminum color coated coils can be as light as 0.18mm (equivalent to 0.06mm steel). 7. Chemical coating machine. 8. Main/finish drying box. 9. Hot/cold laminators; can increase the advantages of material stiffness 10. Installation service. II. Coil coating process flow 1. Production management of pre-treatment stage of coating line. Aluminum coils must be surface treated to remove oil and rust before powder coating. There are more chemicals used in this stage, mainly rust remover, degreasing agent, table conditioning agent, phosphating agent, etc. 2. Powder coating Ensure that the sprayed aluminum rolls are evenly powdered and of uniform thickness to prevent defects such as thin spraying, leakage spraying, rubbing off, etc. Before entering curing, the powder attached to it should be blown off as far as possible to facilitate uniform powdering of aluminum rolls. 3. Heating curing Baking in strict accordance with the process and temperature and time control, pay practical attention to prevent color difference, over-baking or too short a time caused by insufficient curing. 4.Final installation and transportation Characteristics of LITONG aluminum coil coating line 1. Adopt high precision roll coating machine, excellent coating quality. 2. Suitable for acrylic, polyester, and polyvinylidene fluoride (PVDF) coatings. 3. Specifically designed to fit the area of the customer's plant. 4. Fine coating in accordance with international standards. 5. Easy to operate controls, online operator training available. In short aluminum color coating provides a versatile product for the construction industry. Incorrect line design can lead to high scrap rates or inability to handle the full range of products, resulting in far lower production yields and incalculable losses, choosing the right coating line plant and aluminum coil coating machinery is critical for your painted aluminium coils.
