Design of the Atmosphere Protective Hot Dip Refining Workshop of Iron and Steel Alloys
1 Introduction
Iron and steel alloys are a composite metal material formed by combining iron and other alloying elements. At present, it has become a kind of widely used industrial materials, playing an irreplaceable important role in many industries.Due to its wide application, the refining requirements of iron and steel alloys processing are higher, and the atmosphere protection hot dip refining process is one of the commonly used processes. This paper mainly introduces the design of the atmosphere protection hot dip refining workshop.
2 The Process of Atmosphere Protection Hot Dip Refining
The process of atmosphere protection hot dip refining mainly uses the principle of thermal metallurgy. The raw material is first heated in a high-temperature electric furnace or gas furnace and then dipped in a molten metal pool to perform a series of solid-controlled deoxidation-reduction-refinement processes.The resulting alloy contains components such as C, Si, Mn, P, S and other related alloys, and can generally obtain the required performance.
3 The Design of Workshop
3.1 Location
The atmosphere protection hot dip refining workshop shall be set up in a safe and cheerful place, which should not be close to the fire source, flammable and explosive materials.In addition, the layout of the workshop should be spacious enough, taking into account the convenience of production and transportation.
3.2 Structure
The atmosphere refining workshop is composed of electric furnace, refining ladle, charging tank, molding box and other parts.The electric furnace adopts medium frequency or resistance furnace, according to the specific size of stainless steel refining furnace.Refining ladle is equipped with electric stirring device and air exhaust device to ensure the atomization of molten metal.Charging tank is made of stainless steel and other materials.
3.3 Safeguards Measures
The protective measures of hot dip refining atmosphere must be paid attention to in the atmosphere protection hot dip refining workshop.Firstly, it is necessary to select the enterprise grade anhydrous calcium chloride and other drying materials, install an interval heating device, and ensure its good effect.Secondly, it is necessary to install a local exhaust device to absorb the moisture in the atmosphere.Thirdly, it is necessary to pay attention to the environmental protection requirements, for example, set a reasonable ratio of fluorine to chlorine, and strictly control the leakage of fluorine and other toxic gases.
4 Conclusion
The design of atmosphere protective hot dip refining workshop of iron and steel alloys requires not only to meet the requirements of the specific product, but also to strive to make it more reasonable and reasonable, while ensuring the stable and efficient operation of the plant.The design of the atmosphere protection hot dip refining workshop should pay attention to the selection and reasonable layout of electric furnace and relevant equipment, so as to ensure that the refining process can be carried out smoothly and effectively. At the same time, it is necessary to pay attention to the safety measures, so as to better protect the safety of personnel and equipment.
