a primary blowing is performed so as to satisfy the following expression (1) where 蔚 (kW/t) represents the stirring power density by a bottom-blowing stirring gas of molten iron contained in a converter type container, Q (MJ/(min t)) is the product of the low order heat value (MJ/...
Step 1: Determine the size of the metal detector A non-metallic throughput pipe is required to transport the pumped product through the Pipeline metal detection system aperture. The aperture size/diameter of the pipe will be determined by the product throughput rate. ...
Lasers:Lasers work well for cutting sheet steel up to 1/2-inch (1.27-centimeter) thick and aluminum up to 1/3-inch (0.9-centimeter) thick. Lasers are most effective on materials free of impurities and inconsistencies. Lower-quality materials can result in ragged cuts or molten metal splashing...
When you are selecting a metal to use in fabrication, to perform a mechanical repair, or even to determine if the metal is weldable, you must be able to identify its underlying type. Some field metal identification tests can be used to identify a piece of metal. It is necessary to ...
The rarity of a metal is best expressed as its ‘mass fraction’, or how many kg can be expected to be found per billion kg of crust material. Of course, they are not evenly distributed or mining would be impossible, but the number is still useful. ...
Many garages would even allow their customers to take them home and it is also worthy of note that they are made of an alloy of exceptional quality. Nevertheless, many come with connecting rods attached and the rods must be extracted out of the molten metal (combined with ferrous components ...
In laser cutting, more power density creates more heat energy, and how much energy depends on how well a metal, including aluminum, absorbs the energy from the laser beam. But this is just part of the equation. Molten metal needs to be evacuated. A short focal length of the focusing opti...
PURPOSE:To facilitate exchange of a gas blow-in nozzle of a molten metal furnace such as an electric furnace and ensure construction in a short time. CONSTITUTION:A gas blow-in nozzle 2 is mounted on a furnace bottom of a molten metal furnace, and a sleeve brick 4 is mounted on an out...
The lower right side of the bearing casting shows the asbestos shims that are used to prevent the molten metal to be poured in the cap from fusing with the lower half. Photo by Bud Motry Main babbitt bearings may be poured in much the same manner as connecting rod bearings. However, ...
Always wear a welding helmet with a properly shaded lens to protect your eyes from the intense light. Use flame-resistant clothing, welding gloves, and apron to protect your skin from sparks and molten metal. Welding produces harmful fumes and gasses, so you should work in a well-...
