Description

Technical Field

[0001] The utility model belongs to the technical field of sintering and smelting for steel processing, and more specifically, particularly relates to a sintering and smelting device for steel processing. Background Art

[0002] Steel is an alloy composed of iron, carbon, silicon, manganese, phosphorus, sulfur, and a small amount of other elements. Steel is produced from iron ore. In order to improve the performance of steel, iron elements are combined with various trace elements to form a special form, so that the metal has higher technical parameters. It is the most important, main, and most used metal material in engineering technology. Sintering refers to the transformation of powdery materials into dense bodies, which is a traditional technological process. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. Generally speaking, after powder is formed, the dense body obtained through sintering is a polycrystalline material, and its microstructure is composed of crystals, glass bodies, and pores. The sintering process directly affects the grain size, pore size, and the shape and distribution of grain boundaries in the microstructure, and thus affects the properties of the material. Sintered steel is an important type of iron-based part material with the largest output and the widest application in the powder metallurgy industry, and the annual demand has exceeded hundreds of thousands of tons. Sintering is a process in which a powder aggregate undergoes particle coalescence through diffusion under high-temperature heating; the sintering trolley is the main operating component of the steel processing sintering device. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine, receive sintering mixed materials in the upper horizontal section, and after preheating ignition, sintering, cooling, and turning over the materials, return to the head wheel on the return journey to form a transmission cycle to achieve the purpose of sintering the materials.

[0003] Based on the above, the inventor found the following problems: The current sintering and smelting of steel processing generally occur on the sintering trolley. The existing sintering trolley needs to bear the weight of the mixture of iron ore and combustion materials. During long-term use, there is a risk of the sintering trolley breaking and derailing. Moreover, the sealing degree between the existing steel sintering trolley and the air extraction device at its lower end is not high, and the combustion effect of iron ore cannot be maximally improved.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sintering and smelting device for steel processing is provided, in order to achieve the purpose of having more practical value. Summary of the Utility Model

[0005] The purpose and efficacy of a sintering and smelting device for steel processing of the utility model are achieved by the following specific technical means:

The clamping member penetrates through the chamber and extends out of the chamber to be clamped in the limiting groove.

[0009] Further, an arc-shaped groove is opened on one side of the sealing plate facing the running track. One end of the connecting plate far away from the running track is an arc surface. The connecting plate is matched with the arc-shaped groove.

[0010] Further, the I-shaped column and the support column are connected by bolts.

[0011] Further, lubricating oil guiding grooves are provided on the I-shaped column, the sealing plate and the connecting plate.
