Abstract
The utility model relates to a fire cutting device for continuous casting process with strong cooling and injection-suction combination, comprising a cutting torch and a cutting nozzle. The back end of the cutting torch is provided with a cooling water cavity, the front end is provided with a fixing hole of the cutting nozzle, and the middle part is provided with a primary gas mixing chamber. An annular cooling water chamber is arranged on the periphery wall of the fixing hole of the cutting nozzle, an oxygen pipe and a gas pipe pass through the cooling water cavity and are connected in the cooling water chamber, and then the oxygen pipe and the gas pipe are connected with the primary gas mixing chamber. The utility model has the advantages that the cooling chamber is increased about two times than original equal pressure type cutting torches, the cooling effect is strengthened, the injection-suction type cutting torch has low requirement to gas pressure, and the cutting nozzle can be used for ignition with high safety and no tempering.
Description
The utility model relates to the local heat cutting, relates in particular to strong cooling and penetrates suction combined type continuous casting flame cutter tool.
Traditional continuous casting cutting torch is an equal pressure, and its combustion gas, pre-hot gas and hyperbaric oxygen enter cutting torch by independent pipeline respectively.Mix in cutting torch then, i.e. preheat oxygen and combustion gas is to begin to mix in cutting torch, for producing preheat flame.The combustion gas circulation is the pressure that relies on itself, therefore must adopt the medium-pressure or high pressure gaseous-pressure.The result that pressure is high causes poor stability and amount of consumed gas to increase.
Traditional continuous casting cutting nozzle (flame cutting) is a monoblock type, and the life-span is short, difficult processing, and material requires high, the cost height, slot is wide, and is easily overheated, shortcomings such as easy obstruction.
The purpose of this utility model provides a kind of strong cooling and penetrates suction combined type continuous casting flame cutter tool.
The utility model is taked following measures in order to achieve the above object: it comprises cutting torch and cutting torch, the cutting torch rear end is provided with cooling water cavity, outlet pipe, front end is provided with the cutting torch fixing hole, the middle part is provided with gas mixer chamber one time, cutting torch fixing hole perisporium is provided with the annular cooling water chamber, cooling water inlet pipe links to each other with the annular cooling water chamber through cooling water cavity, between annular cooling water chamber and the cooling water cavity by linking to each other cooling water communicating pipe, oxygen hose and Gas Pipe are through cooling water cavity, and after in cooling water cavity, joining, link to each other with a gas mixer chamber again, the cutting torch center is provided with cutting torch cutting oxygen pipe.Cutting torch has cutting torch body, cutting nozzle core, be provided with the secondary air mixing chamber between cutting torch body and the cutting nozzle core, cutting nozzle core head outer wall is provided with rectangular channel, and link to each other with the secondary air mixing chamber, the cutting nozzle core afterbody is provided with mist communicating pipe, mist communicating pipe one, end linked to each other with a gas mixer chamber escape pipe, and the other end links to each other with the secondary air mixing chamber, and the cutting nozzle core center is provided with cutting oxygen Guan Bingyu cutting torch cutting oxygen pipe and links to each other.
Advantage of the present utility model: about cooling chamber doubles than former equal pressure cutting torch, strengthen cooling effect, increase the cutting torch life-span, reduce to the requirement of cutting torch material.Employing is penetrated to inhale and is used for regulating combustion gas and oxygen flow, and guarantees that mist has certain composition, makes preheat flame smooth combustion.The flow of combustion gas is the suction effect of penetrating by oxygen, so injector cutting torch is less demanding to gaseous-pressure.Can adopt low-pressure fuel gas, also available in compression ignite gas, therefore safe and reliable, the combined type mouth is reasonable in design, can be used for automatic igniting, and is safe, energy-conservation, be difficult for tempering.
Elaborate below in conjunction with accompanying drawing.
Accompanying drawing is that strong cooling is penetrated and inhaled the combined type continuous casting flame cutter structure schematic diagram of signing an undertaking.
