REVOLUTION IN DEVELOPMENT OF CHROME-FREE MAGNESIA - AND LOW CHROME HERCYNITE BRICKS
无铬镁砖和低铬铁尖晶石砖发展的革命
In the past， Magnesia-Alumina-Spinel bricks were considered as state of the art for chrome-free kiln linings in the cement industry.
过去，在水泥行业中，镁铝尖晶石砖被认为是最先进的无铬衬砌方案。
Available standard MA-spinel bricks differ mainly in the type of magnesia and in the amount and type of their alumina carrier (sintered and fused MA-spinel， calc. alumina， white fused alumina， etc.)
目前各种标准的镁铝尖晶石砖主要在氧化镁的数量、种类和它们铝载体的种类(烧结和电熔镁尖晶石、钙，氧化铝，白电熔等)方面有很大的不同。
Under severe conditions of modern cement kilns， the high amount of alumina in MA-spinel bricks， required for flexibility， has to be considered as a disadvantage.
在现代水泥窑的恶劣窑况下，用于保证镁铝尖晶石砖的弹性需要的较高铝含量己被认为是一个缺点。
Due to the formation of low melting calcium-aluminates the corrosion resistance and hot erosion strength are reduced.
由于低熔点的铝酸钙的形成，火砖的抗腐蚀能力和抗热蚀强度降低了。
Because of this fact RHI's research work has been focused on reducing the alumina content to a minimum with a simultaneous improvement of the fracture mechanical behaviour.
由于这个原因RHl奥镁公司的研发队伍已经努力于将镁铝尖晶石砖中氧化铝的含量减少到最小量，同时改善了火砖的断裂机械特性。

100% INSPECTION OF EACH BRICK 每一块火砖，100％的检查
In addition to the ISO quality control system， we have our ANKRAL TEST SECTION to monitor the quality of each brick. After a visual check the brick enters ANKRAL TEST SECTION where it passes on ultrasonic test， laser beam measuring and x-ray test； from this the modulus of elasticity， bulk density and cold crushing strength is calculated. In conclusion， RHI bricks offer a double safety for the customers， they are produced according to an ISO 9001 quality assurance certify and are tested by a non destructive method brick by brick. A unique safety offered only by RHI.
除ISO质量保证体系保证产品质量外，奥镁公司还拥有ANKRALTEST SECTION (ANKRAL产品质量检测装置)来监测每一块火砖的质量，产品外观目视检查后，火砖进入ANI(RALTESTSECTION，在该装置上，火砖要进行超声波检测，激光测量，X-光检测，从而计算出火砖的抗压强度和体积密度。总之，奥镁的耐火砖为用户提供双重保险，他们根据IS09001质量标准进行生产并采用非破坏性检测。这种独到的产品质量安全只有奥镁公司能够提供给用户。
From all possible members of the spinel groups， hercynite and galaxite， were found to be the most efficient. Due to the very low amount of alumina required， the sensitivity to corrosion by clinker melt and alkali salts is significantly reduced. A further property is the low permeability that reduces the tendency to infiltration.
在所有可能的尖晶石矿族成员中，铁铝尖晶石和锰铝尖晶石被发现是最有效的(添加剂)。由于需要氧化铝的含量很低，熟料液相和碱盐的侵蚀敏感性得以大幅度降低；从而，低透气性减少了渗透侵蚀的趋势。
Despite the reduced alumina content， the tensile strength of magnesia-hercynite and magnesia-galaxite bricks is kept at a much higher level compared to conventional top grade MA-spinel bricks even at high temperatures (1100℃).
尽管减少了氧化铝的含量，但即使是在1100度的高温下，镁铁尖晶石砖和镁锰尖晶石砖的抗拉强度仍然比常规的顶级镁铝尖晶石砖高很多。
Wedge splitting test： The specific feature of this testing method is the determination of fracture mechanical parameters at high temperatures (1100℃ to 1250℃).
楔劈实验：这种测试方式用于在高温时(1100到1250℃)确定火砖的断裂机械参数。
