Steel rolling equipment
We have been committed to the technical development and research of complete sets of rolling equipment for a long time, and have formed independent research and development technology and production capacity in the fields of long products, plates, and plate and strip finishing production line equipment. There are various types of production line equipment for rebar, round steel, wire rod, H steel, profiles, etc., and the products cover the whole line of process equipment of the production line
The foil rolling mill rolls the strip into the coils of cold-rolled metal of various characteristics with the required thickness and surface roughness in several rolling passes at normal temperature.
The rolling mill is able to roll any metal, especially very hard ones:
Carbon steel - automotive sheet, raw material for making tinplate;
Low carbon steel - advanced processing and special products of advanced processing;
Stainless steel - austenitic, martensitic and ferritic;
Silicon steel - non-oriented and oriented;
High carbon steel - used to make blades, saws, etc.;

AEROGEL BLANKET
Aerogel is the lightest solid material. It exhibits unique properties in mechanics, acoustics, thermics, optics, etc., and is used in many fields such as aerospace, military, medicine, building materials, electronics, metallurgy.
Aerogel is the best thermal insulation material with extremely low density, "endless" hollow walls can minimize thermal radiation. Aerogel can achieve a thermal insulation effect that other materials cannot match. The thermal conductivity coefficient of aerogel is lower than that of air (at normal atmospheric pressure): below 0.018 w/mk. For comparison: kt air = 0.025 w/mk.
Composition
when ethyl silicate is used as a source of silicon obtained by the sol-gel method, small particles of silicic acid sol are formed into a polymer spatial network structure, which turns into a nanoporous structure as a result of aging and can be completely hydrophobic (waterproof) after chemical modification. Then supercritical drying with carbon dioxide is used to replace the liquid in the spatial structure with gas. This air-containing porous structure is an inorganic silica aerogel. The thermal conductivity of aerogel insulation materials at room temperature is below 0.018 w/(mk), and they have excellent insulating characteristics at high temperatures.
R– SI- OH -> R- SI – CH3
Aerogel
• substance with the lowest thermal conductivity in a solid;
• air flow is difficult, convective heat flow is difficult;
• addition of an opalescent agent to limit heat radiation
Disadvantages of traditional materials:
• short service life due to low moisture resistance;
• high maintenance costs;
• formation of condensation between the pipe and the insulating layer;
• severe corrosion under the insulating layer;
• the larger the pipe diameter, the more material layer is needed;
• loose structure.
3 years 3-6 years 6-10 years
Advantages of using aerogel in thermal insulation
• completely hydrophobic material;
• low thermal conductivity;
• high refractoriness;
• high degree of elasticity;
• very low material density;
• long service life;
• inorganic, fire-resistant material is safer and better than traditional ones;
• ability to reuse;
• thinner thermal insulation layer;
• less labor costs;
• increases the available area for use and reduces the space during transportation;
• excellent resistance to ultra-low temperatures;
• convenient in assembly and disassembly;
• ecologicaly clean;
• combines fire resistance and hydrophobicity at the same time.
