Longmen Grottoes

Longmen Grottoes

2023-03-09

Longmen Grottoes, located in Luoyang, Henan Province, is a treasure house of stone carving art with the largest number of statues in the world. It is rated as "the highest peak of Chinese stone carving art" by UNESCO. It is now a world cultural heritage, a national key cultural relic protection unit, and a national 5A-level tourist attraction.

The self-tensioning motor base can avoid these problems perfectly. The design ensures that the belt maintains proper tension throughout the life cycle of the belt, avoiding excessive stretching of the belt and preventing belt relaxation. There is no need to periodically relax or tighten the belt, which guarantees the extension of the belt life and improves the efficiency of the entire transmission system. The self-tensioning motor base reduces downtime, belts are easily installed and removed, and no special training is required to operate the self-tensioning motor base.

The HBI imported in the current season is all used in converter production, and the main charge for the Basic Oxygen Furnace (BOF) is molten pig iron from the blast furnace, commonly referred to as "hot metal" (HM). In addition to iron, blast furnace hot metal contains a certain amount of oxidizable elements, such as carbon, silicon, manganese, and phosphorus.

The common raw material of EAF (electric arc furnace) is scrap steel because scrap steel is cheap and relatively easy to obtain, but social scrap steel often contains unwanted impurity elements. In order to reduce the harmful impurities in the scrap steel, a certain amount of pig iron or sponge iron must be added to dilute the residual metal elements of the scrap steel, which can help keep the content of residual elements in the final molten iron or molten steel at an acceptable level. The advantages of low-sulphur sponge iron are particularly evident in EAF smelting since desulphurisation is not necessary for the furnace , which can save a lot of time.

Supply and demand of DRI in our country

Limited by resources, technology and other factors, the production of DRI (direct reduced iron) in China started late and developed slowly. The production enterprises of DRI in China are small in scale, mainly produced by tunnel kilns, scattered in origin and unstable in production organization, which lead to the difficulties in production statistics. The products are mostly used in powder metallurgy raw materials.

Luoyang

2023-01-12

Luoyang (ancient name——Zhen xun, Xi Bo, Luo Yi, Luo Jing, Jing Luo, Shen Du, Luo Cheng) is also called Yi Luo because of the two rivers of Yi and Luo in its territory. Luoyang, in central China's Henan Province, was named in honor of its situation north of the Luohe River–a tributary of the Yellow River. In ancient China, such a location, or one at the southern foot of a mountain, was deemed to be yang (meaning the sunny side as opposed to yin). Luoyang was thus named. It is one of the first national historical and cultural cities announced by the State Council, one of the four ancient capitals of China, and a world cultural city.

Non-blast furnace iron making technology has grown significantly in recent years, driven by increasing environmental requirements, the need for high-quality steel materials, and especially the Chinese government's commitment to "carbon neutrality" to the world. Non-blast furnace iron-making technology is dominated by the gas-based shaft furnace process, because the gas-based shaft furnace can use hydrogen reduction technology, which greatly reduces carbon emissions, In addition to the gas - based shaft furnace process, rotary kiln, tunnel kiln, RHF and other technologies are also used.

Talking about the role of a mixer in glass production

Talking about the role of a mixer in glass production

2022-09-29

In the production of float glass, the mixing process is a very important link in the production of the mixture, and the mixer is also a very important key piece of equipment. The correct selection and use of the mixer is the basis for improving the quality of the mixture and ensuring the stable quality of the glass.

What are the types of material mixing?

2022-09-22

Material mixing refers to the homogenization of one or more materials to reduce or eliminate the uneven distribution of particle size, density, temperature and plasticity. It is a common material processing method. The following will introduce the classification of materials from the aspects of materials and mixers.

The mixing of high viscosity materials is often encountered in industrial production, and the mixing efficiency and mixing effect directly affect the quality and yield of finished products. The judgment of the mixing endpoint in the mixing time determination is the key, and different researchers have different methods to judge the mixing endpoint, and its accuracy varies.
