Answer: hydraulic casting material by wet curing for 24 hours and 24 hours to the conservation of natural water for large amount of special traditional cement hard castable for hot curing 48 hours hard castable maintenance process shall not be wet, the relative humidity should be below 85% for the conservation of natural water can be hard castable, specific implementation according to the product specification.
9, Q: how castable oven?
Answer: castable general baking system in strict accordance with product instructions, to prevent the adverse consequences caused by the incorrect oven.
10, Q: in the actual working conditions, how to choose the refractory material?
Answer: A, select the appropriate materials, do not choose the material can be considered comprehensive performance price ratio
B, the choice of pouring material or ramming material according to the use of parts and specific construction requirements to choose.
11, Q: refractory refractory classification?
A: A, in accordance with the construction method of pouring material, ramming material, plastic, self material, spray coating
B, in accordance with the hardening method is divided into water, gas, hot
C, according to the classification of binding water cement combination, phosphate binding, water glass combination, ultrafine powder (completely no cement)
D, divided according to the material of high aluminum, silicon carbide, corundum, mullite, clay, magnesium etc.
E, according to the performance of wear resistance, acid and alkali resistance
12, Q: refractory refractory factory inspection routine items?
A: the detection of the performance indicators of bulk density, the rate of change in line, compressive and flexural strength, chemical composition (aluminum, iron, silicon) wear, thermal conductivity, etc..
13, Q: ramming material apply to what part?
Answer: can be used for complex structure for formwork vibrating parts can be used to pick or mechanical ramming material or less important parts, can use manual ramming.
Refractory castable is developed on the basis of low cement refractory castable, which is a kind of refractory castable in recent years. The varieties have high technology, high performance and high purity refractory castable, chromium, carbon and micro expansion refractory castable, mainly used for thermal equipment of steel smelting furnace, ladle, tundish and fluidized bed boiler and regenerative heating furnace, improves the service life, obtain good economic effect.
Using high purity refractory castable or synthetic refractory raw materials and additives, ultra fine powder technology, excellent binder and high efficient additives in refractory materials under the guidance of the basic theory, according to various types of thermal equipment use and operation conditions, scientific material formula, the precise allocation of grain size composition, reasonable selection of binders and additives, preparation a good performance and longevity of the new technology of refractory castable. In the case of high - tech refractory castable for ladle, it is characterized by sub - combination, self - sintering and self - expansion under high temperature. The "three self" principle in the new technology of refractory castable, also have different levels of expression, so its excellent performance, service life significantly improved.
High quality high purity or synthetic refractory raw material is the basis for the preparation of new technology of refractory castables, and also the basis for the production of highly efficient unshaped refractory materials. Such as plate-like corundum, dense corundum, white corundum, corundum mullite, spinel, high purity magnesia and spherical alumina clinker etc.. In addition, using high quality bauxite as raw material, through the process of sintering ingredients or fused, made of Zong Gangyu
