What requirements should refractories meet?

Refractory materials used in a variety of high temperature equipment, which is subject to physical and chemical erosion and mechanical damage under high temperature conditions, the performance of refractory materials should meet the following requirements: 1, high refractoriness Modern metallurgy furnace and other industrial furnace heating temperature are generally between 1000 ~ 1800 ℃. Refractory materials should have a low melting temperature at high temperatures. 2, high temperature structural strength should be large.... [Lire la suite]

Focus on the refractory industry and optimize the structure

Since 2000, China's refractory industry has entered the fastest-growing stage and is now the world's largest producer and exporter of refractory materials. European Refractories Manufacturers Association survey of the global refractory production in 2011 showed that the global refractory output in 2011 was 42,750,000 tons, of which, China's refractory output was 29,500,000 tons, accounting for 69% of the global output. With the relative trend of the company's shares Pu-resistant shares, Beijing Lill major innovation...

Refractory production process introduction, glass technology

According to the degree of compactness and shape of different products, there are sintering, casting and melt casting method. Sintering method is to pre-burn the department of raw materials into clinker, crushing and screening, and then press a certain ratio and raw materials mixed by forming, drying and firing. Casting method is the raw materials through mixing ingredients and fine grinding and other processes, melting at high temperatures, direct casting, cooling and crystallization, annealing products. Their compact...

Refractories enterprises facing difficulties and countermeasures

At present, the production environment of refractory materials is not optimistic. The main reason is that the products produced by high-temperature industries such as steel, nonferrous metals, glass and cement are in surplus. The market for refractory materials is reduced. The competition among similar enterprises in the industry is harsh. At the same time, Concerned that the financing difficulties, coupled with the difficulty of funds back to the production of enterprises has brought great difficulty, if we encounter... [Lire la suite]
