A new unburned brick was prepared from the Ti-bearing blast furnace slag as an aggregate and PVA modified by epikote as cementitious materials.
Therefore, epikote-modified PVA [9-10] is used as cementitious materials to prepare slag brick with the virtues of high quality and low price.
Experimental Materials. polyvinyl alcohol (1750 ± 50) , epikote, auxiliaries are all purchased from Sinopharm Chemical Reagent (Shenyang) co., Ltd.
Fig. 1 The relationship between the compressive strength of slag brick and addition amounts of raw materials Summarizing the study, the optimized mass fraction of raw materials for the preparation of slag brick should be 6% of epikote-modified PVA, 6% of auxiliary 1, and 10% of auxiliary 2.

Some reports show that Acheson graphitization furnace with SiC synthesis materials as insulation material can produce not only graphite but also SiC.
So the finite element method is selected to analyze Co-production furnace that graphitization process apply LWG method and the insulation material is SiC synthesis materials [8].
According to the technology analysis, the temperature field is unsteady and the synthesis materials' properties are nonlinear.
