Refractory Brick--Tradematt Refractory Manufacturer

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 . 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

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.

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

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

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

Energy and environmental problems to the iron and steel enterprises and the ceramic industry and other industries to bring the rapid development of restrictive effects, energy saving and reduce emissions is the enterprise technological progress and can be the energy and environmental pollution, energy and environmental pollution, The inevitable choice for sustainable development. Industrial furnace is the key equipment for industrial heating, widely used in the national economy of high temperature industry. Industrial kiln is also a large energy consumption, its energy consumption accounts for 25% of the total energy consumption, accounting for about 60% of total industrial energy consumption. In the energy saving process of industrial kilns, in addition to heat source transformation, sintering process transformation, combustion process transformation and furnace structure transformation, the furnace refractory and kiln refractory material performance is good or bad energy saving effe

Refractory brick masonry should be staggered brick joints, brick need to use refractory mud (dry puzzle with dry refractory powder) to fill, masonry process until put into production, to prevent masonry damp. In order to compensate for the volume expansion of the masonry after heating, the masonry needs to be designed according to the design and specification requirements. Refractory brick masonry wall, bottom, roof, pipe lining, brick lattice, combined brick masonry and expansion joints set aside. Masonry wall in accordance with its form is divided into two types of straight wall and curved wall. Straight wall before the masonry, the furnace floor should be the lowest level of the base surface leveling, on the basis of the furnace or steel structure according to the construction line. Measuring the vertical and horizontal center line and other reference line, in ensuring the size of the various parts of the furnace under the principle of accurately find the wall size line. Wall

High alumina bauxite clinker is calcined bauxite. Generally,before Alumina Bauxite in the production of high alumina refractory bricks are  the calcined, get clinker, that is, barren material. With this High alumina bauxite clinker as the aggregate in the ingredients, can guarantee the volume stability of the refractory bricks and the size of the accurate. China's bauxite is mostly D-K type, in the calcination process to be decomposed dehydration, secondary mullite and re-crystal sintering three stages. The calcined mineral composition forms corundum, mullite and glass phase according to the ratio of Al2O3 and SiO2 in the raw material. High bauxite clinker is gray, light yellow and dark gray. It is mainly used to produce high alumina refractory bricks, can also be used to make fused corundum. The two major causes of sintering of high alumina bauxite are secondary mullite and liquid phase effects. The former depends on the Al2O3 ratio, which hinders the sintering effect; the la
