Product details
Oxygen lance is composed of three parts, lance nozzle, oxygen lancing pipe body and the end of the lance. Role of the end of the lance is to fix the oxygen gun to the transmission device, and through the cooling water and oxygen.lancing pipe body sends the cooling water and oxygen to the spray gun head, also to the work location of oxygen lance nozzle.The role of oxygen lance nozzle for converter oxygen to metal.Oxygen lance of converter of high speed kinetic energy is the main purpose of oxygen pressure energy conversion, thus achieve the goal of blowing into the molten pool.In order to achieve this goal, needs to have a hole, to form oxygen requirements (flow rate is generally higher than Mach 1) and the speed of shape.The hole is in the form of a special, laval oxygen lance nozzle is the most widely used, can better control the shape of the oxygen flow rate and spray forming.Because the oxygen gun working environment temperature is very high, core can reach 3000 degrees Celsius, so gun head by copper casting processing, and cooling water is piped in, in order to make sure the gun head did not burn up.
Head of the oxygen lance can be called oxygen lance nozzle or copper head, there was once a oxygen gun hole, because now the problem is not solve the single-hole oxygen gun, now basically is more than one hole, its principle and shares the same oxygen flow, multiple nozzle quick space and the formation of a large number of flow also has the property of single-hole spray lance flow, but the area, the greater the oxygen utilization rate is higher.
