Description
Technical field
The present invention relates to a kind of caravan ventilator cowling, belong to technical field of metal material.
Background technology
With the rapid development of world economy, more and more Newly Sprouted Things are also comed one after another, the living standard of people
Gradually lifting, multinational trip, whole world trip etc. is becoming increasingly popular.And the appearance of caravan, the people instantly for hobby tourism bring good fortune
Sound.Onboard sleep, it is key factor to pay attention to ventilation, and the application of ventilator cowling is extremely important, and ventilator cowling is usually by materials such as steel, aluminium
Matter is made.
Steel alloy history more than 100 years existing.It is strong to the sixties, mainly development of high strength steel and superelevation after World War II
The epoch of steel are spent, due to the needs that aircraft industry and rocketry develop, it is new many high strength steels and unimach occur
Steel grade, such as precipitation hardenable high-strength stainless steel and various Hi-Stren steels are its representational steel grades.The sixties with
Afterwards, steel alloy starts to develop to the direction of high-purity, high accuracy and Ultra-low carbon, and Maraging steel, ultra pure iron element occurs
The new steel grades such as body stainless steel.
Steel alloy refers to based on iron, the conjunction for adding the elements such as a certain amount of copper, nickel, manganese and controlling carbon content and forming
Golden system.Steel alloy has high intensity, high rigidity and certain ductility, particularly suitable for making structural material, therefore extensively should

For Fe and impurity.
The present invention steel alloy raw material proportioning in, using manganese as deoxidier and desulfurizing agent, wherein manganese with aboundresources,
The characteristics of efficiency is various, while titanium and oxygen, sulphur, nitrogen have extremely strong affinity, its deoxygenation, sulphur removal, the ability denitrogenated are more excellent,
It can make steel alloy that there is higher intensity and croop property.Addition degasser lithium in the raw material of steel alloy of the present invention, and lithium
Chemism it is stronger, lithium is added in steel alloy, lithium and the elemental gas such as the hydrogen in alloy, oxygen, nitrogen react generate it is close
Small and low-melting compound is spent, not only removes these impurity elements, more so that metal becomes fine and close, moreover it is possible to eliminate in metal
Bubble and other defects, so as to improve the structure of alloy, improve the mechanical performance of alloy.Meanwhile the addition of raw material of the present invention
The more conventional formula of metal element content is all few, can be greatly cost-effective, expands benefit.
Preferably, in caravan ventilator cowling component, impurity includes N ＜ 0.05%, S ＜ 0.05%, O ＜ 0.03%, H ＜
0.03%.Elemental gas in alloy be easy to cause material internal hole, so that product is easy to crack, reasonable selection of the present invention
Material, makes full use of between element to the strong content for attracting, greatly reducing impurity element in alloy of impurity element.
The present invention additionally provides another technical solution while reasonable selection material mixture ratio：
A kind of preparation process of caravan ventilator cowling, the method include the following steps：
(1) melting：Component and its mass percent configuration raw material as described in claim 1, alloy is melt into by raw material
Liquid simultaneously pours into alloy-steel plate；
