Owing to the status that the price of thermal insulating agent for liquid metal has been raising constantly in recent years, the present work investigated the properties of carbonized corn straw using as thermal insulating agent of liquid metal. The results showed that the carbonized corn straw possessed higher content of fixed carbon, smaller repose angle (or better flowing property) and lower heat conductivity coefficient compared to carbonized rice husk. Both the laboratory test and practical application of using carbonized corn straw as thermal insulating agent of liquid metal showed that it had a better thermal insulating performance, whereas a bigger collapse ratio and agglomeration were found. Thus, a satisfied application performance of thermal insulating can be achieved by using a mixture of carbonized corn straw and carbonized rice husk. The application of carbonized corn straw as thermal insulating agent of liquid metal not only develops a new effective way to use corn straw, but also contributes to decrease the production cost of metallurgical industries. 相似文献

Monolithic materials with a strong thermal insulating effect are required by the foundry industry for further energy savings, meanwhile possible premature wear of refractory linings caused by over-insulation should be avoided. A monolithic insulating material containing lightweight aggregates possessed strong thermal insulation and was proposed to replace the traditional insulating material made of chamotte currently used in a channel induction furnace. To evaluate the new lining concept, creep of the working lining was considered in the finite element modelling and followed the classical von Mises creep model, which was defined with the Norton–Bailey strain hardening creep equation. The results showed that the lightweight design of the insulating lining reduces the heat loss from the steel shell and material consumption. Moreover, the thermomechanical loads in the refractory linings and steel shell remain within a reasonable range when compared with the currently in-use refractory lining concept. 相似文献

The effect of thickness of magnetic conductor and number of electrically insulating layers on the magnetic properties in an alternating field of a layered powder-metallurgy soft-magnetic material based on iron was investigated. It was determined that increasing the thickness of the magnetic conductor and frequency of the alternating current deteriorated the magnetic properties of the material. Creation of a layered structure in which ferromagnetic layers alternate with electrically insulating layers decreased specific magnetic losses. 相似文献
