The process of aluminum extrusion as well as the technical control point for temperature three

Extrusion speed, tractor speed, extrusion rod speed, quenching speed, and annealing speed are the primary control points used in aluminum extrusion production technology. These primary control points are China die casting manufacturer broken down into three temperatures. In order to improve the efficiency of aluminum extrusion processes, it is absolutely necessary to make a financial investment in machinery of a high quality. This is especially true of the extrusion machine, the aluminum rod heating furnace, and the mold heating furnace, as these are the three components that are the most vital to the process.

The temperature of the aluminum rod, the temperature of the outlet, the optimal temperature for extrusion, the speed of the tractor, the speed of the extrusion rod, the temperature of the mold, the temperature of the material barrel, the quenching temperature, the type of alloy, the aging process, the optimal metal physical properties, yield, and production efficiency, and a heat analysis of aluminum tape and aluminum rod during extrusion are all factors that will be considered. It is necessary to preheat the aluminum material before pressing it in order to ensure that the magnesium contained in the aluminum rod will melt and flow uniformly throughout the material. This makes it possible to bring the temperature up to a level that is relatively close to the solvus. According to the graph, there is not a significant shift in temperature that occurs when the rod of aluminum is put into the extruder. On the graph, this is represented as a straight line across the middle. If there is a significant enough increase in temperature, the zinc alloy die casting supplier aluminum will melt, and the profile will not be formed. The solidus line denotes the point at which a further increase in temperature is considered to be hazardous. The Temperature at Which Aluminum Rods Are PreservedIt is recommended that the temperature of the aluminum rod be kept between 420 and 440 degrees Celsius, with a preference for temperatures in the 420 to 440 degree Celsius range.

 

When the temperature is too low, the extrusion process will be slowed down (due to the fact that the aluminum material needs to be pliable), while when the temperature is too high, it will cause tearing. The vast majority of the frictional force that is produced during extrusion will be converted into heat, which will lead to an increase in temperature. This will be the case because the frictional force will cause the temperature to rise. The temperature of the aluminum rod, the temperature of the mold, and the temperature of the extrusion cylinder are the three temperatures that are discussed the most frequently. In addition to this, it is of the utmost importance to precisely control the speed at which the extrusion is occurring. In the event that this does not take place, the magnesium and magnesium that are present in the aluminum alloy will not be able to be melted, and the performance of the metal will not be impacted in any way. Nevertheless, it must not be higher than the line that indicates the point at which solids will begin to melt. In order to achieve the best possible temperature during the extrusion process, it is necessary to make adjustments to both the speed of the process and the temperature of the aluminum rod. This will result in the desired temperature difference during the extrusion process. neither lower than the temperature of the solvus nor higher than the temperature of the solidus, which is 620 degrees Celsius. Neither lower than the temperature of the solvus nor higher than the temperature of the solidus. The temperatures at which an alloy reaches its solvus point are not consistent from one alloy to the next.

 

The efficiency of the production can be significantly gleaned from the speed at which the tractor travels.There is no way to generalize this information.In today's modern western world, extrusion profile factories are capable of reaching tractor speeds of up to 80 meters per minute.
The rate at which rods are extruded.An additional significant indicator of productivity is the rate at which extrusion rods are produced.This is expressed as a rate in millimeters per minute, which is more commonly referred to simply as "per minute.".

 

Temperature of the mold in the DieOven. The temperature of the mold is an extremely important factor to consider when attempting to determine the overall quality of the extruded profile. If this does not take place, it will almost certainly lead to a blockage, and it may even cause damage to the mold. temperature of the cylinders that are being storedAt all times, the temperature of the storage cylinder must be kept at approximately 426 degrees Celsius. This temperature must be kept constant. a temperature that is capable of putting an end to somethingThe purpose of the quenching process is to bring about the solidification of alloying elements, more specifically magnesium and atoms. To keep the profile's strength intact, this helps to prevent magnesium and other atoms that are prone to instability from precipitating and stabilizes those atoms that are already present.

There are primarily three different kinds of quenching methods, and die casting mould they are air cooling, water mist cooling, and water tank cooling. The speed of the extrusion, the thickness of the profile, and the required physical properties, most importantly the strength requirements, all play a role in determining the type of quenching method that is applied.

 

O annealed state, suitable for processed products obtained by annealing to obtain the lowest strength and cast products obtained by annealing to improve ductility and dimensional stability, O can be followed by an Arabic numeral other than zero. O is suitable for processed products obtained by annealing to obtain the lowest strength and cast products obtained by annealing to improve ductility and dimensional stability. O is appropriate for processed products obtained by annealing to obtain the lowest strength and cast products obtained by annealing to improve ductility and dimensional stability. Both of these applications are suitable for O. H work hardening state, appropriate for products whose strength can be increased through work hardening, and H is always followed by two or more Arabic numerals; H is a work hardening state. H state of work-hardening workW solution heat treatment state, which is only appropriate for alloys that are naturally aged at room temperature after solution heat treatment, and only for alloys that are naturally aged at room temperature after solution heat treatment. It is possible to specify the amount of time that an alloy has been allowed to age naturally by using this unique code, such as W1/2 hour. Products that are manufactured in a stable state after being subjected to T heat treatment are compatible for zinc die casting manufacturer use with other products that are manufactured in a stable state after being subjected to T heat treatment. The effects of getting older are primarily comprised of the following:In order to increase the overall strength of the profile, it is necessary to reorganize the alloying elements in such a way that they can be distributed uniformly throughout the entire profile. Only then can the profile achieve its full potential.

 

When the nominal length of an aluminum profile is between 3 and 6 meters, the allowable deviation of the length is 15 millimeters. When the nominal length is longer than 6 meters, the allowable deviation is 25 millimeters. Temperature and the passage of time are two indicators that demonstrate the necessity of artificial aging being subject to stringent control, and these indicators demonstrate that artificial aging must be subject to such control. In the artificial aging furnace, it is absolutely necessary for all of the individual components to keep the same temperature throughout the entire process. In order to achieve the best possible metal physical properties, it is necessary to select the appropriate aluminum alloy as well as its best shape, select the appropriate quenching (cooling) method, apply the appropriate aging temperature, and control the aging time. All of these steps must be performed in order. It is necessary to choose the appropriate aluminum alloy in order to attain the best possible results when it comes to the physical properties of the metal. The yield rate is an additional essential measure that helps to determine how productive a production system is. The yield was one hundred percent.

 

It is physically impossible to achieve this objective due to the scratches that were caused by the tractor and the stretching machine. Doing so would inevitably lead to the extrusion of the cutting head (Butts) and the cutting off of the material. During the process of extrusion, a yield of approximately 85 percent is considered to be the maximum that can be achieved. The average yield rate that can be achieved by domestic extrusion factories in China is somewhere between 70 and 75 percent.
