The effects of heat treatment on the properties of multi-element wear-resistant low-alloy steel (MLAWS) which is used to make the liner of rolling mill torus were researched. The results show that when quenching temperature is lower than 900 °C, the hardness increases with the increase of temperature, and when quenching temperature is higher than 9...

The understanding of oxidation behaviors on H13 steel was helpful to improve the service life and performance of hot work moulds and dies. Thermal-Calc Software was performed to calculate the oxidation phases on H13 steel along with different partial oxygen pressures in the interesting temperature range of 500–700 °C. In this range H13 steel sample...

A new technology for treating waste plastics (WP) by traditional coking process was introduced. With a thermo-balance and a 10 g atmospheric fixed bed reactor, the thermo-gravimetric behavior and product were studied during co-coking of WP with blended coal. And then, using a coke-oven with capacity of 200 kg, the characteristics of products were a...

Twin-roll strip casting is regarded as a prospective technology of near net shape continuous casting. The fluid flow field and level fluctuation in the pool have a strong influence not only on composition and temperature homogeneity of pool, but also on the strip quality. A 1 : 1 water model of a twin-roll strip caster was set up based on the crite...

ZrB2 in MgO-C composite materials obtained by both microwave sintering synthesis and in-situ reaction at lower temperature was investigated. The test result shows that 66. 67% of reactant changed into ZrB2, and the other form Al203, which could optimize the properties of carbon-containing materials. Therefore, the method of in-situ synthesizing ZrB...
