Description

Nodular cast iron type oxygen rifle saliva set

Technical field

The utility model belongs to metallurgical casting industry, more particularly to a kind of nodular cast iron type oxygen rifle saliva set.

Background technology

Oxygen rifle is the key equipment of pneumatic steelmaking, it is desirable to which oxygen blown penetration power is strong, quick heating, there is sufficiently high stir to molten bath Mix ability.The operating condition of oxygen rifle saliva set is severe, and converter burner hearth is high temperature heterogeneous system, and flame zone temperature is up to 2500 DEG C.

Traditional oxygen rifle saliva set uses steel structural form, and under high-temperature work environment, yielding cracking, causes steel construction Leak so that the service life of oxygen rifle saliva set is very short, while is brought to the operation and maintenance that operator covers oxygen rifle saliva Greatly difficult, the operating temperature of operator is also very high, and influences the continuous production at scene, reduces production efficiency.

In view of this, field technology personnel are directed to researching and developing a kind of improved oxygen rifle saliva set, to solve traditional oxygen rifle Technical problem caused by saliva set.

The content of the invention

The task of the utility model is to provide a kind of nodular cast iron type oxygen rifle saliva set, utilizes the high-temperature and durable of spheroidal graphite cast-iron The characteristics of intensity and high temperature fatigue strength excellent performance, suitable Heat-resistant Ductile Iron Containing is selected, design rational casting knot Structure, while two cooling water pipes are set in the casting body of spheroidal graphite cast-iron, thus solve caused by the above-mentioned prior art Problem.

The technical solution of the utility model is as follows：

A kind of nodular cast iron type oxygen rifle saliva set, the water jacket are heat-proof nodular cast iron, and cooling water pipe is housed in water jacket, cold But water pipe is disposed with U section and straight section, and the quantity that cooling water pipe is set in spheroidal graphite cast-iron water jacket is two, forms four disengaging Mouthful.

A kind of nodular cast iron type oxygen rifle saliva set of the utility model utilizes the creep rupture strength and high temperature of spheroidal graphite cast-iron The characteristics of fatigue strength excellent performance, select suitable Heat-resistant Ductile Iron Containing, designs rational casting structure, while in ball Two cooling water pipes are set in the casting body of black cast iron, by the calculating of rational tube type design and intensity of cooling, are rationally arranged Cloth cooling water pipe moves towards, using circulating water, to reach optimal cooling effect.

The nodular cast iron type oxygen rifle saliva set of the utility model has the characteristics that and technical advantage：

1st, it is unlikely to deform, it is water-tight.

2nd, wall thickness is thin, and cooling effect is good.

3rd, service life is grown, and not slagging is non-maintaining.

Brief description of the drawings

Fig. 1 is a kind of structure diagram of nodular cast iron type oxygen rifle saliva set of the utility model.

Fig. 2 is the top view of oxygen rifle saliva set as shown in Figure 1.

Fig. 3 is the A direction views in Fig. 1.

Reference numeral：

1 is cooling water pipe.

Embodiment

Elaborate with reference to the accompanying drawings and examples to the utility model.

Referring to Fig. 1 to Fig. 3, the utility model provides a kind of nodular cast iron type oxygen rifle saliva set, and water jacket is cast for heat-resisting spheroidal graphite Iron, is equipped with cooling water pipe 1 in water jacket, cooling water pipe 1 is disposed with U section and straight section.Cooling water pipe 1 is set in spheroidal graphite cast-iron water jacket The quantity put is two, forms four inlet and outlet.

The nodular cast iron type oxygen rifle saliva set of the utility model utilizes the creep rupture strength and fatigue at high temperature of spheroidal graphite cast-iron The characteristics of strength character is excellent, selects suitable Heat-resistant Ductile Iron Containing, designs rational casting structure, while cast in spheroidal graphite Two cooling water pipes are set in the casting body of iron, by the calculating of rational tube type design and intensity of cooling, are rationally arranged cold But water pipe moves towards, using circulating water, to reach optimal cooling effect.

The advantages of nodular cast iron type oxygen rifle saliva set of the utility model is to be unlikely to deform, water-tight；Wall thickness is thin, cooling effect Fruit is good；Service life is grown, and not slagging is non-maintaining.

Certainly, the those skilled in the art of the art are it should be appreciated that above-described embodiment is intended merely to illustrate this practicality It is new, and the restriction to the utility model is not used as, as long as in the spirit of the utility model, to above-mentioned implementation Change, the modification etc. of example will all fall in the range of the utility model claims.

Claims

A kind of 1. nodular cast iron type oxygen rifle saliva set, it is characterised in that：The water jacket is heat-proof nodular cast iron, is equipped with water jacket cold But water pipe, cooling water pipe are disposed with U section and straight section, and the quantity that cooling water pipe is set in spheroidal graphite cast-iron water jacket is two, shape Into four inlet and outlet.
