2580 cubic blast furnace hearth pouring and repair   The integral pouring of the blast furnace hearth is a new technology that uses amorphous refractory materials to repair the hearth lining. Compared with the traditional hearth carbon brick and ceramic cup brick masonry process, it has the advantages of short construction period and saving maintenance costs. The seventh generation of the No....

Is it better to use hanging bricks or castables for the lining of the waste heat furnace of waste incineration?   The classification of domestic waste is one of the core measures of the country to promote the construction of ecological civilization. With the gradual advancement of domestic waste classification, the calorific value of waste has increased significantly. This is because after cl...

What is ramming mass? Refractory ramming mass are made of a high proportion of granular and powdery materials and a low proportion of binders and other components, or even all of them are composed of granular and powdery materials. They are bulk materials that need to be constructed by strong ramming. The refractory materials for induction furnace linings should meet certain conditions to cope wit...

What is the difference between castables and ramming materials?   What is the difference between castables and ramming materials? Both products belong to amorphous refractory materials. Ramming materials are constructed by ramming and hardened by heating. Castable materials are constructed by pouring and can be hardened without heating. So what is the difference between ramming materials and ...

(1) Blast furnace volume (2) Air volume (3) Top pressure (4) Oxygen enrichment (5) Number of iron holes (6) Opening system (7) Required iron hole depth (8) Iron hole angle (9) Average furnace grade. (10) Designed daily output. (11...

Tap hole clay composition The quality of the raw materials of the taphole mud has a great impact on the quality of the taphole clay. Now large blast furnaces basically use high-purity raw materials to improve the quality of the taphole mud, which is generally composed of the following materials: Silicon carbide SiC has the characteristics of corrosion resistance, high temperature resistance, high ...

Taphole clay has been subjected to higher demands due to the development of blast-furnace smelting technologies. Taphole clay is no longer a consumable refractory but a functional one. It is not only responsible for sealing the taphole but also protecting the bottom side walls of furnaces and maintaining the stability of tapholes [1,2,3,4]. During operation, molten iron-slag constan...

ASC castables for iron troughs are generally low-cement or ultra low cement castables, which are mainly composed of Al2O3 aggregate, SiC, carbon, cement and various additives.     (1) Al2O3 aggregate Al2O3 aggregate is the main component of the castable and is the particle skeleton of the castable. Al2O3 aggregate mainly includes fused white corundum, brown corundum, sub-white corundum, ...
