用于成形耐火产品的微硅
用微硅定制成型耐火砖的性能
耐火材料：应对各种材料和形式
成型耐火材料作为各种尺寸和形状的预烧“积木”，并采用标准砌体技术进行安装。
成型产品或耐火砖的优点在于可以根据温度轮廓和热变化定制尺寸和材料成分，防止腐蚀和炉渣，排斥接触耐火衬里的熔化材料，并能适应壳体的几何参数。
成型产品还允许在安装工艺上有广泛的选择，考虑材料成本、所需设备、人工成本、劳动法规及合同或监管要求，以及时间限制和安装技能和当地服务提供商的可用性。
成型产品的性能可以通过微 硅 进行定制，以满足特定的加工和终端产品特征，并为耐火材料制造商提供额外优势，即在安装前可进行现场预测试，确保满足客户需求。
这使得制造商能够精确选择耐火壳体的尺寸、格式、物理性能和化学耐受性等各类形式，确保关键部件在高温和可变冷热循环下的完整性，抵抗化学腐蚀和机械应力。成型零件制造商还可以添加剂以改善干粉流动、促进密度，并在高温下获得粟米石/鋏石的形成。
ELKEM MICROSILICA：®高性能成型产品的质量基准
Elkem作为全球微硅技术领导者，提供多种ELKEM MICROSILICA®产品，适用于成型零件。这些定制的硅或铁硅制造副产物由超细、非晶态的二氧化硅球（SiO2）组成，具有高纯度特性，对各种高温应用的具体性能要求有显著影响。
以下是我们用于制造成型产品的非详尽清单，其中许多产品也适用于铸造品（未成型产品）和预制件：
耐火材料用硅基材料
Elkem Microsilica® 971
The ELKEM MICROSILICA® 971 product, a high quality, purpose-made, low-impurity grade, for versatile applications in refractories, available in densified (D) or undensified (U) form, to be used in advanced refractory products such as self-flowing, low, ultra-low and no-cement castables.
Product data sheet
Elkem Microsilica® HQ
The Elkem Microsilica® HQ product is a cost-effective alternative for low cement castables, with controlled and stable chemical composition, based on low alkalis and higher reactivity.
Elkem Microsilica® 968
The ELKEM MICROSILICA® 968 product, a cost-effective alternative for low cement castables, featuring a controlled and stable chemical composition.
Product data sheet
Elkem Microsilica® 955
The Elkem Microsilica® 955 product, a medium-quality grade silica fume with tight specification limits based on in-process control, resulting in higher silica content and reduced impurities.
Product data sheet
SioxX®
Designed for microsilica-containing LCC and ULCC, based on Al2O3 - SiO2 system with quick wet-out and low water demand.
SioxX®-Quick
Designed to act as an accelerator in undispersed aluminosilicate systems like dry gunning LCC and ULCC mixes without clay.
SioxX®-Zero
Designed for microsilica-gel bonded systems (NCC) to control the working and demoulding time and to develop high green-strength at room temperature.
SioxX®-Flow
Designed to work as a multi-functional microsilica dispersant, for aluminosilicate LCC, ULCC and NCC, giving customers freedom to fine-tune their products with other additives (accelerators, retarders, etc.). It enhances the rheological properties, reduces the water demand and increases the flow. Suitable also for shotcreting.
By combining both SioxX®-Flow and SioxX®-Set products, setting can be controlled. SioxX®-Flow product will also work in combination with Silica-Sol (colloidal silica) in NCC to control flow, working and setting time.When used in silica-sol systems a separate gelling agent needs to be added.
SioxX®-Set
Designed for undispersed systems mainly for NC gunning mixes. Can also be used for LC and ULC gunning. In castables and shotcrete (dispersed systems) SioxX®-Set can be used as accelerating agent.
SioxX®-Ten / SioxX®-Ten PLUS
SioxX®- Ten and SioxX®- Ten PLUS are primarily designed for ultra low cement alumina-based or microsilica-gel bonded no-cement castables.
SioxX®- Ten mainly works at the range of 800-1100ºC, while SioxX®- Ten PLUS is recommended to work at the range of 600-900ºC.
Both of them enhance the rheological properties, reduce the water demand, increase the flow, control the working and de-moulding time, help develop high green strength as well as high strength at the indicated working range of temperature.
SioxX® Mag
Designed for basic (MgO-based) refractory castables, to help avoid inherent problems of crack formation and poor workability. For advice how to best use our Specialties, contact our competent technical staff.
