Abstract
The utility model provides an oxygen lance nozzle of a converter with a water plate. The oxygen lance nozzle comprises a total oxygen channel, a plurality of spray orifice channels, a water inlet channel, a water outlet channel, a water plate of the water outlet channel and an end plate, wherein the plurality of the spray orifice channels are communicated with and penetrates through the total oxygen channel, the water inlet is enclosed outside nozzles, the water outlet channel is located below the water inlet channel, the water plate is used for separating the water inlet channel from the water outlet channel, and the end plate is located below the water plate; and the water plate is a separating type element. The oxygen lance nozzle of the converter with the water plate can effectively reduce the temperature of an end plane of the oxygen lance nozzle of the converter, improve the production efficiency of the converter and reduce equipment and personal potential safety hazards, and has simple structure, great economic benefit and application value.
Description
Technical field
The utility model relates to a kind of Oxygen Lance Nozzle for Converter with pocket water plate.
Background technology
Along with the continuous enhancing of china's overall national strength, the national economy stable development, Infrastructure is constantly perfect, and China has become the country of World Steel output first, also is simultaneously iron and steel consumption big country.Converter steelmaking is the important component part of Iron and Steel Production, and the oxygen rifle is one of key equipment of oxygen converter steelmaking.The life-span of shower nozzle is directly determining the life-span of oxygen rifle, and guarantees that it is one of emphasis of oxygen rifle design that shower nozzle is effectively cooled off.And in traditional making processes, realize cooling by pocket water plate, but this pocket water plate is formed by monoblock casting, because the singularity of structure, the pocket water plate of casting is often because molding and sand removal is very difficult and moulding is very poor, so when shower nozzle is worked, greatly reduced the reasonable layout of current, affected the performance of shower nozzle.
Summary of the invention
The utility model purpose provides a kind of Oxygen Lance Nozzle for Converter with pocket water plate.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Oxygen Lance Nozzle for Converter with pocket water plate, it comprises: total oxygen path, be connected with total oxygen path and run through its body several spray orifice passages, be centered around the spray orifice outside inlet channel, be positioned at the inlet channel below water outlet, be used for separating into and out of the pocket water plate of water channel and the end plate that is positioned at pocket water plate below, wherein pocket water plate is the separate type element.
Preferably, the center of described pocket water plate has a limbers.
Preferably, described pocket water plate is the assembly element of some five equilibriums.
Preferably, the diameter of described limbers is 80 millimeters.
Because the utilization of technique scheme the utlity model has following advantages:
Can effectively reduce the end face temperature of Oxygen Lance Nozzle for Converter, simple in structure, improve converter production efficiency, the potential safety hazard of minimizing equipment and the person has very large economic benefit and use value.
Description of drawings
Fig. 1 is cross-sectional schematic of the present utility model;
Embodiment
Embodiment: as shown in Figure 1, a kind of specific embodiment with Oxygen Lance Nozzle for Converter of pocket water plate for the utility model provides, comprise total oxygen path 10 on its head body, be connected with total oxygen path 10 and run through its body several spray orifice passages 12, be centered around the outside of spray orifice 12 inlet channel 20, be positioned at inlet channel 20 belows water outlet 30, be used for to separate into and out of water channel 20,30 pocket water plate 40 and the end plate 50 that is positioned at pocket water plate 40 belows.Wherein pocket water plate 40 is the separate type element, and is namely non-one-body molded with head body, and end plate 50 is one-body molded with head body.The centre of pocket water plate 40 forms the limbers 42 of diameter 80 millimeter, and this limbers 42 is between spray orifice passage 12.Pocket water plate 40 is divided into the quartern in the present embodiment, adopt the way of assembling to be assembled into the corresponding position, avoided casting flaw fully, not only made the current reasonable layout, the more important thing is to have solved that pocket water plate can't moulding or the bad difficult problem of moulding in the present oxygen lance blow head making processes.
The utility model can be so that Oxygen Lance Nozzle for Converter end face ensemble average temperature drop reaches about 10 ℃, and more than nose probe (central zone) drop in temperature of Oxygen Lance Nozzle for Converter thermal load maximum reached about 30 ℃, this can prolong the work-ing life of shower nozzle greatly.And ring end face in the Oxygen Lance Nozzle for Converter, advance in the end face of shower nozzle end to have produced stronger rotational flow with water coolant, these have the formation of the rotational flow of strong turbulence characteristic, greatly reduced the dead zone area of flow of cooling water, so that water coolant is with the larger speed Oxygen Lance Nozzle for Converter end face of flowing through, taken away more heat, final so that Oxygen Lance Nozzle for Converter end face bulk temperature is obvious downtrending.In addition, formed regular clockwise direction rotational flow at the middle portion water coolant, the turbulent flow performance of Oxygen Lance Nozzle for Converter end water coolant has been strengthened in the formation of these eddy flows greatly, has reduced dead zone area.
Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
