Safety, No Backside Dead Middle:Twin braking protection with Mechanical and electrical , if servo motor lose voltage, the press will cease and brake instantly. Carbon paste electrodes are produced from mixtures of a carbon powder with an inert liquid (paraffin oil, silicone and so forth.) which is an electrical insulator and which is insoluble in the electrolytes used. They noticed that the era of a micro-crack network resulted from the formation of phases with completely different thermal growth coefficients and the formation and decomposition of the Al2TiO5 after the thermal shock exposure resulted in a higher thermal shock resistance 34 Ghasemi et al., studied the impact of the addition of zero, 2, four, 6, and 8 wt. % of Al2O3 micro and nanoparticles on MgO-C refractory ceramic composites sintered at 1650 °C 35 They discovered that 6 wt. % of alumina nanoparticles promoted the densification of the MgO-C refractory and higher values of cold crushing strength had been obtained with respect to the additions of microparticles as a result of majority presence of MgAl2O4, Al4C3, and AlN phases. In the case of the sample with three wt. % ZrO2 nanopowders, the typical thickness of the layer chemically attacked with out the phases of CaZrO3 and ZrO2 was 392 μm, after this point these phases blocked the advance of the slag, see Determine 7 (iii). They found that ZrO2 nanoparticles have been simpler than ZrO2 microparticles to increase the densification and hydration resistance of MgO-CaO refractories 19 In other work of the same authors, they reported that adding Fe2O3 nanoparticles to CaO refractories allowed to improve the sintering process, however they also observed that the resistance to hydration increased due to the formation of phases with low melting level (2CaO.Fe2O3, CaO.Fe2O3 and 3CaO.Al2O3) located in crystalline defects 20 These low melting point phases have much less tendency to soak up water than free CaO 20 In the same means, they studied the addition of ZrSiO4 nanoparticles in MgO-C refractories, and so they obtained phases with excessive oxidation resistance and a dense matrix with small amount of voids and porosity 21 Shahraki et al. 22 confirmed that the addition Al2O3 nano and microparticles on MgO-CaO refractories allowed to improve the physical, mechanical, and thermal properties of the refractory.
