Description of RHF process in China

Description of RHF process in China

2023-01-05

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

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?

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.

Method of determining the mixing end point of high viscosity materials

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.

For cold-consolidated pellets, molasses can be used alone as a binder, some of which may need to be diluted during use and a certain temperature is required. Molasses can also be used as a binder together with other materials. For some pellets that need special use, molasses may also be used as the main raw material to add other materials to prepare a binder with composite properties.

High viscosity self-cleaning mixing equipment is mainly used in the field of adhesive substances, cosmetic products, lubricants, pigments, resins, rubber and plastic auxiliary substances, emulsions, industrial dyes and other chemical products, in these areas it has played its strengths with its unique features, so that the prospects are very good. High viscosity mixer is a collection of dispersion, stirring and mixing as one of the multifunctional and efficient equipment, more and more enterprises, researchers love. So specifically how is the high viscosity mixer used in the paint industry?

The effect of quenching method on the hardness of the roller skin of the briquette machine

The effect of quenching method on the hardness of the roller skin of the briquette machine

2022-08-03

In this paper, the effect of double-quenching on the surface hardness and heat treatment deformation of the roller skins was investigated using 9Cr2Mo steel roller skins for briquette machine, and the parameters of the double-quenching process were determined. The results show that by using the double-quenching method, the outer surface of the roller skin forms a hardness gradient distribution with high hardness in the middle and low hardness at the edges, and the heat treatment deformation of the roller skin is reduced and the service life is significantly improved.

Technological elements of rubber production

Technological elements of rubber production

There are many kinds of rubber products, but the production process is basically the same. The basic process of rubber products with general solid rubber - raw rubber as raw material includes: plasticizing, compounding , calendering, pressing, forming, vulcanization six basic processes. Rubber processing process is mainly to solve the contradiction between plastic and elastic properties of the process. Through a variety of technological means, make the elastic rubber into plastic plastic, and then add a variety of coordination agent made of semi-finished products, and then through vulcanization make the semi-finished products with plastic and high elasticity, good physical and mechanical properties of rubber products. Below, this article focuses on the rubber plasticizing and mixing these two processes.
