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/...
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...
but also to prevent wear and tear. The most common usage is applying zinc to a steel or iron object. Industrially, the method mostly commonly used is hot dip galvanization, which involves dipping the object in molten zinc. However, do-it-yourself galvanizationuses electroplating, which is ...
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 ...
No tool is quite as cool or as fun to watch as a gas blowtorch. The showers of illuminated sparks that shoot from a blowtorch at work are mesmerizing. But don't let the pyrotechnics draw you too close -- these sparks actually are small pieces of moltenmetalthat spit off during cutting ...
A neutralizing reagent is added to a solution of chloroplatinic acid containing impurities to adjust the pH value of the solution to 5.5-7.0, the insoluble impurity compounds that precipitated in this first neutralization step is filtrated off, a neutralizing reagent is added to the first filtrate...
How to Make the Mini Metal Foundry : How to make a simple backyard foundry for less than $20, for melting pop cans, and casting aluminum.
The metal cold-casting process is faster and much less expensive compared with foundry casting of molten metal.
Molten steel, razor sharp blades, lots of time to himself... what could possibly go wrong? Stoick: What am I going to do with him, Gobber? Gobber: Put him in training with the others. Stoick: No, I'm serious. Gobber: So am I. Stoick: He'd be killed before you let the...
For years we have been dealing mostly with the opposite trying to get backward compatibility, getting lead-free parts into a tin-lead assembly. But the traditional things on leads and components and so forth is strip off the solder through a molten immersion dilution process, such as you have...
