by Norma PrietoThere are two types of heat treating: cold and hot. Cold heat treating, also known as gas welding is a quick method to apply metal parts or components to a workable state. The process heats the metal up to approximately 1700 degrees Fahrenheit within a fraction of a second and it is usually done with boron or other appropriate catalyst. The hot method on the other hand is considered the traditional way to do things because of its ability to treat larger pieces of metal faster and more effectively.
For every type of metal or alloy there is a corresponding alloy preparation process. In order for the metal to achieve the melting point (or austenitizing) necessary for the casting process you need to take the proper steps in the casting process as well as after the heat treating has been done. It is important to know the differences between these processes and what they are meant to accomplish. Once you understand the differences between the two, you will be able to cast metal with ease and efficiency.
Cold processing refers to casting metal using an electric arc and a variable speed electric furnace. Many times a custom manufacturer will utilize the high pressure steam turbines found in water plants for this purpose. These turbines operate at higher temperatures than most standard foundries and they produce castings with higher melting points. When you have a higher melting point alloy you can create castings that are stiffer and stronger than cold steel. In the world of custom manufacturer it is important to have the right tools and supplies available.
The world of steel foundry is a fairly simple world compared to what it really is when you go down to machining steel. When we talk about a cold steel foundry we are talking about a variety of different things. This includes both electrical and hydraulic machinery and a variety of robotic equipment. The process involves heavy pressure being placed on a piece of steel while it is being pulled or pushed. When you are looking at a traditional CNC or PC machine, the machine will send signals to a CNC or PC operator who will then place the pressure on the metal being pulled.
With steel foundry the operator places the pressure on the metal and the robotic arm grabs onto it and pulls it through the machine. For this type of work to occur in an office environment you have to have a variety of different forms of coverage. You have to find commercial insurance agents that will insure the machines you are using. You also have to find commercial insurance agents that will insure the individuals that will be working in the foundry as well.
When you are working in a professional foundry, you will have to have a variety of insurance coverage to cover all of the individuals that are participating in the foundry as well as the material that is being used. The other type of coverage that needs to be considered for a foundry is that which covers any damages to property during the process of the casting or machining as well as any indirect damages done to the property during the process. Indirect damages can include things such as water damage to buildings and homes. Professional liability insurance is required when you are doing professional work in a potentially risky situation.
There are various different types of steel that are used in foundry processes. The different alloys that are used are alloyed steel, high carbon steel, cold rolled steel, mild steel, soft steel and cold rolled alloy steel. In order to determine what alloys you are using you need to have a qualified structural engineer to inspect the site and the foundry for you. These engineers will also help you to determine the melt curve, yield point and fatigue life of the different metals that are being used in the foundry process.
There are also several different types of processes that can be used in metal foundries including strip casting, gas tungsten casting, direct casting and water jet casting. If you are involved in the manufacture of any type of metal where the properties of the metals are vastly different then you may need to have the equipment necessary to differentiate between the various types of metals that are being used in the fabrication. There are so many different processes that are used in metal foundries and there are so many different types of metals that are used that it is impossible to list them all in this short article.
