Product Details

Oxygen lance is composed of three parts, a gun head, a gun body, the tail of the gun. The effect of the end of the gun is to fix the oxygen lance on the transmission mechanism, and through the cooling water and the oxygen. The gun is the transfer of cooling water and oxygen to the gun head, is also sent to the working position of the gun head parts. The function of the gun head is to supply oxygen to the metal in the converter. Converter oxygen lance is the main role is to oxygen pressure energy transformation for the high-speed kinetic energy, so as to achieve the purpose of blowing molten pool. In order to achieve this goal, need to have a hole to make the oxygen to form conforms to the requirements (generally above Mach 1 flow rate) and the shape of the velocity. This hole is a special shape, and Laval type gun head are the most widely used and the gun head can better oxygen flow rate and the shape of the liquid jet formation. Because oxygen lance of the ambient temperature is very high, core area can reach 3000 degrees Celsius, so gun head are with copper casting processing, which pass into the cooling water to ensure the gun head was not burned. It is almost like this principle, there is nothing to understand the question.
Right, a gun head of the oxygen lance can also called nozzle or copper head, used to have a hole oxygen lance, now because of single hole oxygen lance problems is very much out of no, now basically is above the hole, the principle is the same, several nozzle of oxygen flow shares will soon in space and the formation of a large stream also have single hole oxygen lance stream characteristics, but the area is larger, the oxygen utilization rate higher.
