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 have sufficient strength, good rigidity, do not take shape, do not shift, do not leak pulp. Steel mold
Board to use mold removal, wood template to brush waterproof paint. Reuse of wood before cleaning and then use.
Third, the pouring material mixing stirring time should not be less than 5 minutes. Operation to use a forced mixer, stir
Mix the dry mix, then add 80% solvent stirring, and then depending on the degree of wet and dry construction and specific parts of the request, and then slowly add the remaining solvent until the appropriate working consistency until. In ensuring the construction performance of the premise, the amount of solvent should be less good.
Refractory castables should be used in the whole bag, stir well refractory castables  must be finished in 30 minutes. In the high temperature drying of the operating environment but also to shorten the time. Has been initial coagulation or agglomeration of refractory castables shall not be used, do not add solvent stirring and then use.

Important operation of energy saving in industrial kiln

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

Analysis of High Bauxite Clinker Quotes

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

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
