预制耐火产品用微硅
利用微硅材料提升零件完整性并减少预制耐火砖的磨损
耐火材料：使用不同材料和格式满足复杂需求
预制（或预制）耐火材料通常形状复杂，直接安装在炉子和窑炉的功能部件中——显著减少安装时间和维护停机时间。
模块化预制零件提供特定的热和机械特性，可在现场预先测试，确保在安装前满足客户需求。这使得制造商能够在燃烧单元外制造非常复杂的耐火衬里模板，使窑炉和炉子能够持续运转。这也使耐火材料制造商能够用更高等级的材料衬砌现有关键部件，提升耐火壳体的物理性能和耐化学性，包括：
- 保护关键部件免受高温影响，同时保持持续高温，减少热量流失，抵抗化学攻击，以及因极端高温或周期性冷热循环产生的机械应力。
- 防止锅壳、原料和耐火材料各部分最终产品之间产生不必要的反应，如磨损或化学反应。
微硅：实现多功能且复杂的预制件制造
Elkem作为全球微 硅 技术领导者，为预制件带来了多项优势，因为它能够制造更灵活、易于安装并完美嵌入现有结构的零件。Elkem MICROSILICA®预制零件产品是硅或 铁硅 制造的定制副产品，由超细、非晶态的二氧化硅（SiO2）球体组成。它们具有高纯度特性，能对高温下各种应用所需的特定特性产生显著影响。
典型的预制成型部件包括烧煤炉、入口室、鼻环、耳顶、窑罩和槽口覆盖、再热炉中的坝和堰、浇注头、龙头块、冷却入口喉和工作台、牛鼻炉、滚炉绝缘材料等。
它们也用于燃烧块、内底陶瓷空气和气体喷嘴，以及钢包衬里（铝业）。
以下是我们为制造预制零件提供的产品清单，其中许多产品同样适用于成型和非成型产品。Elkem 专家、技术人员和销售人员随时为您提供针对您具体应用的合适解决方案：

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.
