Abstract
The utility model belongs to the technical field of steel making equipments, in particular to a new expanding-contracting joint coated oxygen lance, which comprises an inner layer of steel pipe and an outer layer of refractory coating. The utility model is characterized in that the two jointing ends of the oxygen lance have no layer of refractory coating; that the internal diameter of one end is expanding in the shape of a cone, and the outer diameter of the other end is contracting in the shape of a cone, the expanding diameter and the contracting diameter being matched with each other; that the thickness of the refractory coating varies from 2 to 10mm, being divided into two ranges of 3-5mm and 5-10mm, and the refractory coating of different thickness can be selected to satisfy different requirements in use; and that the assembly can be done by simply inserting the contracting end into the expanding end. The utility model has the advantages that the utility model can increase the work rates and can reduce the work strength of the operating staff; that the joint part has sound tightness without gas leakage, removing potential safety hazard; and that the oxygen lance can satisfy the various requirements of the customers, helping steelworks reducing the steel making costs.
Description
Technical field
The utility model belongs to steel-making and uses equipment field, particularly a kind of novel scalable formula joint coating oxygen blowpipe.
Background technology
STEELMAKING PRODUCTION, particularly Electric furnace steel making production for quickening fusion process, all adopts oxygen blast to flux, and used oxygen lance develops into aluminizing pipe from common steel tube, develops into coated pipe again, and developing into from individual tubes can interconnective pipe fitting.Present oxygen lance mode of connection all adopts and is threaded.The shortcoming of thread connecting mode is outside positive thread is exposed to fully, be easy to wounded, scratch, cause connecting difficulty, even do not connect, promptly enable to connect, also will leak gas because of poorly sealed, reduced the oxygen blast effect, even may cause taking place security incident.
Summary of the invention
The purpose of this utility model provides a kind of novel scalable formula joint coating oxygen blowpipe.
The purpose of this utility model realizes by following technical proposals.
Novel scalable formula joint coating oxygen blowpipe of the present utility model, comprise inner layer steel pipe and outer refractory coating, it is characterized in that joint, oxygen lance two do not have refractory coating, the tapered hole enlargement of internal diameter, the tapered undergauge of other end external diameter, hole enlargement and undergauge tapering mate mutually.
Described refractory coating thickness is 2-10mm.
Described refractory coating thickness is 3-5mm.
Described refractory coating thickness is 5-10mm.
The advantage of this oxygen lance is: connect very convenient, as long as first inserting toward hole enlargement with undergauge, just can finish connection work, alleviated labor intensity of operating personnel, and since hole enlargement tapering and undergauge tapering be complementary, good seal performance after pegging graft, air tight, eliminated potential safety hazard.Refractory coating thickness can change according to customer requirements, can adapt to the requirement of different user.Owing to adopted the socket connection mode, oxygen lance is fully used, do not waste the one-inch oxygen lance, can save substantial contribution, reduce steel-making cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
As shown in Figure 1, novel scalable formula joint coating oxygen blowpipe of the present utility model, comprise inner layer steel pipe 2 and outer refractory coating 3, it is characterized in that joint, oxygen lance two do not have refractory coating, the tapered hole enlargement 4 of internal diameter, the tapered undergauge 1 of other end external diameter, hole enlargement 4 and undergauge 1 tapering mate mutually.
According to different service requirementss, can select different refractory coating thickness, generally in the 2-10mm scope, can be divided into two class of 3-5mm and 5-10mm.
