After pouring, the temperatures of the outer and inner wall of the mold materials is recorded until the temperature reach the steady state condition.
The mechanical properties of the casting materials are investigated by observing the microstructure and performed Vickers Hardness Test on the casting specimens.
In the findings, the thermal conductivity k, of the mold materials is almost the same.

Study on the Function of Steel Tube Concrete in the Fire Prevention DESHENG Zhu1,a, LEI Shi2,b 1Fire prevention division of Qingdao fire department, Qingdao, 266071, China 2School of Materials Science and Engineering, Shandong Jianzhu University, Fengming Road,  Jinan 250101,China aliukg163@163.com, deshzhu126@126.com, bslcqj@sdjzu.edu.cn Keywords: steel tube concrete; fire prevention; mechanical property Abstract: Using circumferential constraint action of steel tube to concrete, steel tube concrete makes concrete be in the condition of three-dimensional pressure, to increase the strength of concrete and enhance the plastic performance.
Due to the existence of the concrete could prevent or delay the steel tube from crippling, it makes steel tube material performance can be fulfilled.
Steel tube concrete can not only make up two materials their shortcomings, but also give full play to the advantages of both.
Second, due to the characteristics of mutual contribution, coordination and complementary, between steel tube and concrete which consist of steel tube concrete, when the temperature goes up, two kinds of materials work together, and take changes of load distribution caused by the temperature going up, which can play their excellent properties of two materials.
