ã€China Aluminum Industry Network】 1. Alloy Elements
6063 alloy is an alloy made of aluminum, magnesium and silicon as the main elements, each element has a certain amount of content, magnesium offer is high. Some manufacturers in order to cut costs, the amount of magnesium to the minimum allow the content. Some even worse, the content of magnesium is lower than the minimum required. Some factories add waste wires and waste pot aluminum waste pots to alloys, leaving no basis for 6063 alloys. As a result, the mechanical strength of aluminum profiles is very low, and it can be as low as twists and turns with two hands and one bend. Commonly known as "noodles" are the same soft. This is one of the reasons why aluminum can be cheap for several thousand yuan.
The standardized aluminum manufacturers have internal standards in the manufacture of alloy components, that is, within the scope of various elemental contents, each plant has its own smaller scale of change, and the aluminum, magnesium, and silicon share requirements are very strict. Each factory has its own data and keeps it confidential. There are qualified alloys formulated to ensure quality, otherwise how to process later, the quality will not go up.
2. Aluminum alloy melting furnace
How to melt with a good 6063 alloy, with a crucible furnace, which is also essential, and now the domestic selection of the furnace has the level of the 40's, but also the level of the 90's, the poorer manufacturers use the initial crucible boiler. There are coal-fired, oil-burned, gas-fired and electrically heated smelting furnaces. Some stoves have chimneys, and some have no chimneys. The most commonly used are square-shaped furnaces (rectangular furnaces). The leading ones are circular furnaces. Some circular furnaces can skew aluminum water. On the tonnage of one ton, two tons, five tons, ten tons, twenty-five tons and fifty tons of aluminum melting furnace. Contrast to the lead, in the following aluminum melting furnace and then add a static furnace, static furnace 6063 alloy used in the important manufacture, can remove the slag in this furnace degassing, standing, and then forging aluminum rod for kneading applications. The quality of the alloys produced in the initial coal-fired furnaces and in the modern circular furnaces is certainly not the same. In general, the furnace, regardless of the burning of thorium fuel, should have a chimney. Most of the waste gas generated during the burning of fuel can be discharged from the chimney. If the smokeless exhaust gas residue is completely melted in the aluminum water, the aluminum rod for kneading is cast, and there is a severe slag inclusion bubble inside. This is one of the reasons for the low quality of the aluminum material, which is also one of the reasons for the low price of aluminum. .
3. Alloy forging
The level of domestic forging equipment is very different. The older forging equipment in China has the level of iron forging in the 1940s, and the leading hydraulic forgings are forged. Iron die casting rods have very poor crystallographic arrangements and contain many slags and bubbles in the casting rods. The quality of the casting rods is very poor. Nowadays, the contrasts commonly used in factories are horizontal forging (also known as continuous forging) and semi-continuous forging. Most semi-continuously forged wire rope drives, better hydraulic transmission. Half-forged rods vary in length, usually 3 meters, 4 meters, up to 8 meters. Semi-continuous forging is a pit type, which reduces on one side while forging, and is cooled on all sides with cold water, because the water cooling is evenly distributed and the crystals of the cast rod are uniformly arranged. However, when the wire rope is driven downwards, it is not as smooth as the hydraulic transmission. The surface of the hydraulic forged cast rod is lubricated compared to the surface of the other cast rods. The surface lubrication of the cast rod is one of the prerequisites for kneading the profile. Casting the surface of the cast rod with other methods is relatively rough. In order to ensure the quality of the profile, sometimes the cast rod is first hit by a knife, and the car goes to cast the rough surface of the rod. Today's commonly used semi-continuous forging die is a leading, hot-top, horizontal forging die. The characteristics of this die can be cast several to several dozen at a time, casting quality together is good, with a high quality 6063 aluminum alloy cast rod There are talents who can produce good aluminum profiles. If the forging equipment with the initial staleness can not forge good casting rods, the base can not produce good aluminum profiles. There are many aluminum factories in China, and there are no equipments for producing aluminum rods. Instead, 6063 alloy rods are purchased from electric aluminum plants or other factories. Such aluminum plants and aluminum materials are in the hands of the cast rod factory. Aluminum is difficult to reach the quality and stability. Compared with leading forging equipment with backward equipment, the first is low investment and low production costs, which is one of the reasons why the difference in the sale price of aluminum.
4. Profile kneading
China's profile kneading machine has a wide variety of products, and has a wide range of unevenness. It is also a world comparison. There are factory-owned simple kneading machines that can be transformed with plastic extruders. There are a few domestic ones, followed by Taiwanese, devils, the United States and Germany, with hydraulic and hydraulic pressure. In total, hundreds of kneading machines in China are all kinds. It is better to think that devils, the United States, and Germany have better kneading machines, followed by Taiwan. Good and poor kneading machines, with the same cast rods, the quality of extruded profiles is never the same. We often see the use of 6063T5 for the construction of aluminum doors and windows, which is a universal US trademark.
Our trademark is LD31RCS. Both T5 and RCS indicate conditions that indicate artificial aging conditions in air-cooled and quenched. The quenching of metals is quenched by high temperatures and quenched by low temperatures. For example, steel blades must be hardened and sharpened in water. The quenching of aluminum is also water-cooled and quenched. Construction with 6063 profiles that use air-cooled quenching, the quenched aluminum material in the aging furnace aging time, aluminum crystals rearranged, the mechanical strength increased significantly. In all metal alloys, as long as the aluminum alloy is in a state of limitation.
Picking the right shower tray can be difficult given the huge array of options that are now available. The first thing to consider is the space available as this can quickly narrow your options down making the decision easier however if a large showering area is desired then there are almost endless possibilities. Apart from the obvious size considerations, expect to have to choose which material, shape and colour you require.
