1.Self-flowing refractory castables are suitable for difficult-to-construction parts, relatively narrow corners, and cannot be constructed with refractory bricks or vibration. The refractory self-flowing castable itself has good fluidity and can be automatically filled with compaction without vibration.
2.Self-flow refractory castable is a principle that can flow on its own, and it flows with water to a lower point. The self-flowing castable refractory is a new type of unshaped refractory material developed by using low-cement formula and being upgraded for difficult construction.
3.Refractory self flowing castables strictly control the particle grade, add silicon micropowder, and use surfactant, which has automatic air discharge, automatic compaction, easy mixing, good fluidity, low water consumption, fast drying speed and low creep rate. Etc.
4.Self-flowing refractory castables are classified into clay, high alumina, mullite, corundum self-flowing castables and self-flowing refractory products according to the refractory materials used and temperature. Zhengzhou Rongsheng kiln refractory manufacturer provides customized and free samples.
5.The application of the heating furnace, the water cooling pipe of the heating furnace is wrapped with mullite self-flowing refractory castable, good results are obtained. The use of self-flowing refractory castables to make burner bricks and repair the roof of the furnace and the damaged parts of the furnace wall also has good performance. The use of self flowing refractory castables to build furnace linings facilitates construction, but the cost of building materials is increased by about 50%, which is sometimes difficult for users to bear. To this end, the overall cost of self-flowing refractory castables should be reduced to facilitate their promotion.
6.The refractory aggregate for self-flowing refractory products for heating furnaces uses tertiary alumina clinker, sometimes adding first-grade bauxite clinker and mullite aggregate. For the refractory powder, special grade clinker clinker powder, corundum powder and mullite powder are used. At the same time, a-Al2O3 and SiO2 ultrafine powder and expansion agent are added, and alumina refractory cement is used as a binder and a phosphate water reducing agent is added.
7.The water consumption of the self-flowing refractory castable is slightly higher than that of the vibrating product of the same refractory material, but the strength of the self-flowing refractory product is high, and the change of the line after burning is small. Because the refractory material can self-leveling and venting well, it is reasonable in granule size classification, which can achieve the tightest packing density. The choice of binder and ultrafine powder and water reducing agent is reasonable and the dosage is the best, so it can be used for customer service water consumption. The defects that come, improve their performance.
8. The application of ladle, the new non-silicon ash alumina magnesia self flowing castable has obvious effect when repairing ladle permeable bricks. The refractory product has less water addition and self-flowing non-silicon ash-aluminum-magnesium self-flowing casting without vibration.This refractory product improves the overall corrosion resistance, replaces the inadequacies of amorphous refractories, and achieves results for the steel smelting industry.
