Performance of ladle refractory castables and ramming materials

The ladle is one of the important thermal equipment in steelworking. Modern industry, in order to save energy, most companies choose unshaped refractory materials and not burning brick as a ladle refractory lining. Ladders are mainly used in the early selection of siliceous and high-alumina amorphous refractory as its lining. In recent years, more choice of ramming lining and refractory castable and vibrating lining. Its primary raw materials are zircon stone, semi-zirconium, waxy stone, aluminum chrome and so on. 1, refractory ramming material Ladle with refractory ramming raw materials are: wax stone, zircon stone, semi-zircon stone, high aluminum and aluminum chrome, aluminum and magnesium and so on. With a refractory ramming material ramming Sheng Gang bucket wall, the lining thickness and brick masonry when the same. According to the damage of the barrel lining, the various parts of the fire resistance ramming material is not the same. Russia, a factory 80 ~ 360t ladle, through

The banding technology of granular refractory fiber castable

The banding technology of granular refractory fiber castable . Granular refractory fiber castable high strength, excellent thermal shock resistance, good insulation properties. As the columnar aggregate formed by the small stress, and will not damage the coherence of the product, and its own cross-network structure, can resist external force, so that the material has a strong mechanical properties. In the conventional refractory fiber castable , as the aggregate of refractory fiber cotton without oil into one, in the mixing process, the mud continued to penetrate into the pores of the fiber, the destruction of the fiber insulation effect, and granular refractory fiber casting The material still retains the fiber porosity, and the dispersion is more uniform, the bulk density is also larger than the ordinary refractory fiber products, which determine the granular refractory fiber casting material with better insulation effect. Comparison of Heat Loss Between Water - tube Casting and C

The development and production of refractory materials

Refractory industry , as the national industrial production and production and operation will not be one of the basic materials, one of the high temperature industry has not played an important role, is the transformation of the entire industry restructuring of the industrial base. "13th Five-Year" period of China's refractory industry also ushered in the domestic traditional refractory industrial transformation and strategic new industry fast and powerful new opportunities. 2017 China's refractory industry is to enter a face of transition challenges, the use of new energy, new technologies, new equipment, a high-speed development period. The face of 2025 Chinese production and the Internet + strategic layout, refractory companies how to master this round of opportunities to carry out, in-depth implementation of innovation strategy, leading career development, occupy the forefront of professional shopping malls? From the refractory network, Shanghai Shenshi Exhibition

What is aerogel insulation blankets and how to use ?

图片
JODA offers high performance aerogel insulation blankets for both hot and cold service applications. Aerogel blanket insulation products have been widely used in industrial and building insulation markets for over a decade. The unique patented process integrates aerogel into a fiber-batting reinforcement to create flexible, resilient and durable aerogel blankets with superior insulating properties. The aerogel part of high performance insulation blankets is comprised of synth etic amorphous silica (SAS). The other major ingredient in this products is a non-woven, needled batting comprised of either E-glass fibers or a blend of polyester (PET) fibers and E-glass fibers. Synthetic amorphous silica has been produced for more than 100 years for a variety of uses (adsorbents, fillers, anti-caking agents) and consumer products (toothpaste, cosmetics, food, animal feed). The US EPA recently listed synthetic amorphous silica as a chemical on the Safer Chemical Ingredient List, part of the

Construction of refractory castables

First, the pre-construction inspection Before the construction inspection should be strictly carried out, including the following 1. Clear the structure of the castable material and clean it 2. Art hole set aside 3. The construction equipment of the intact, vibrating tools must have a good use of pieces 4. Anchor type, size, layout and welding quality, metal anchors must be done for expansion compensation 5. around the refractory brick insulation layer to do a good job of cast water loss (glue) preventive measures 6. The packaging and date of the refractory castables  and the pre-test to check for failure 7. Construction water quality must meet the quality of drinking water 8. Implementation of the construction process recipe 9. Pouring procedures above check the failure should be handled before passing the construction, expired failure of the material shall not be used. Second, the construction template can be made of steel or hardwood (bamboo) made. Template to h
