耐磨不是单一指标。高温工况下的失效大多来自烧损、变形、脱落与结构提前终止，所以我们把材料、结构、工艺三件事捆在一起设计。 Wear resistance is not a single metric. Most high-temperature failures come from burn-through, deformation, detachment and premature structural failure — so we design materials, structure and process as one.
同一个溜槽上，鹅头区、落料点、出口段的温度和磨损机理都不一样。我们为不同区间开发了各自的材料，再用激光熔覆、堆焊等工艺让它们和基体冶金结合。 Within a single chute the gooseneck, impact zone and outlet see different temperatures and wear mechanisms. We developed separate materials for each and bond them metallurgically to the substrate by laser cladding and overlay welding.
针对高炉炉顶温度超高、打水急冷等工况研制，具有良好的高温强度、抗腐蚀与抗裂纹延展性能。800℃ 时应力 21MPa，而溜槽最大工作应力仅 4~5MPa。 Developed for extreme furnace-top temperatures and water-quench shock, offering high-temperature strength plus resistance to corrosion and crack propagation. It carries 21 MPa at 800 ℃ against a maximum working stress of only 4–5 MPa.
高温强度余量 4 倍以上Over 4× strength margin在 700~900℃ 温度下硬度不降反升，900~1000℃ 仍保持较高硬度，具备高温耐磨性。经德国法奥迪公司实验数据验证。与钢基体冶金结合后在高温下不易脱落。 Its hardness rises rather than falls between 700 and 900 ℃ and stays high at 900–1000 ℃, delivering genuine high-temperature wear resistance — verified by test data from Fauldi, Germany. Metallurgically bonded to the steel substrate, it resists detachment under heat.
900~1000℃ 硬度不降反升Hardness rises at 900–1000 ℃在 400~600℃ 下具有高硬度，与 DSYH900 配合使用，保证溜槽在不同温度区间都有对应的耐磨能力，而不是只顾最高温区。 High hardness at 400–600 ℃, used alongside DSYH900 so every temperature band has matched wear protection rather than optimizing only for the hottest zone.
与 DSYH900 分区配合Zoned with DSYH900用于高压辊柱钉。在晶粒细化、钴与钨结合优化基础上匹配硬度、强度及韧性；在独家开发的疲劳磨损试验机上检测，失重比德国领军企业柱钉少三分之二。 For HPGR studs. Grain refinement and optimized cobalt–tungsten bonding balance hardness, strength and toughness; on our own fatigue-wear rig it loses two-thirds less mass than the leading German supplier's studs.
失重比德企少 2/32/3 less mass loss配合中低合金钢辊面基体，可在现场对局部进行耐磨补强，甚至进行补块，不必整套下线更换。这是"中低合金基体 + 网面防磨"技术路线成立的前提。 Paired with a low-to-medium alloy roll body, it allows local wear reinforcement or even patching on site instead of replacing the whole assembly — the precondition that makes the "medium-alloy body plus mesh protection" route viable.
支持现场局部修复Enables local on-site repair采用德国定制技术生产，具有优异的高温耐磨性。用于烧结单辊系统时，在 800℃ 高温下硬度保持 HRC60 以上。 Manufactured under customized German technology with excellent high-temperature wear resistance. In the sintering single-roller system it retains HRC60+ at 800 ℃.
800℃ 保持 HRC60 以上HRC60+ at 800 ℃用于高炉风口小套。2000℃ 超高温防烧、1400-1600℃ 长期稳定运行，并与紫铜基体高强度结合。同时降低热输入，减少冷却水带走的热量。 For blast furnace tuyeres: burn resistance to 2,000 ℃, stable long-term service at 1,400–1,600 ℃, and high-strength bonding to the copper substrate — while cutting heat input and the energy the cooling water carries away.
耐温 2000℃ / 稳定 1400-1600℃2,000 ℃ peak / 1,400–1,600 ℃ stable晶粒细化 + 钴钨结合优化，匹配硬度 / 强度 / 韧性；配合高耐磨高韧性侧板防止边部坍塌。中低合金辊面基体保留现场堆焊修复能力。 Grain refinement with optimized cobalt–tungsten bonding balances hardness, strength and toughness, paired with tough side plates that prevent edge collapse. The medium-alloy roll body keeps on-site overlay repair possible.
疲劳失重较德企少 2/32/3 less fatigue mass loss专有热应力定向释放技术防止变形影响布料矩阵；无受力联接焊缝设计防止热裂纹危害；长鹅头设计避开接口在高温区的烧损。详见发明专利 ZL 202110795994、ZL 202111294692.1、ZL 202222163128.2。 Proprietary directional thermal-stress release stops distortion from disturbing the charging matrix; load-free weld joints prevent thermal cracking; the extended gooseneck keeps interfaces out of the hottest zone. See invention patents ZL 202110795994, ZL 202111294692.1 and ZL 202222163128.2
多重防翘起、防翻板、防脱落设计，以及外壳烧穿时的防漏料技术。包钢曾发生衬板翻起被迫休风 5 小时的事故，这类失效必须在结构上排除，而不是靠材料硬度。 Multiple designs against lifting, flipping and detachment, plus leak protection should the shell burn through. A liner lift-up once forced a 5-hour blow-down at Baotou Steel; failures of this kind must be eliminated structurally, not by hardness alone.
多耐磨材料复合运用与耐磨结构组合设计，适应各类高温、冲刷、腐蚀等工况。耐磨钉结构让耐磨层深入基体，溜槽可耐磨厚度达 120~150mm。 Composite use of several wear materials combined with wear-resistant structures suits high temperature, erosion and corrosion alike. Wear-stud structures drive the protective layer into the substrate, giving chutes 120–150 mm of usable thickness.
整流扁平出口有效控制料流厚度与方向，所形成的料环带宽度不发散、厚度均匀。详见发明专利 ZL 202111315930.2 与日本授权 特許第7745935号。 A rectified flat outlet controls stream thickness and direction so the burden ring neither spreads nor varies in depth. See invention patent ZL 202111315930.2 and Japanese grant 特許第7745935号.
使用精准布料溜槽提高布料均匀性后，可进一步优化布料矩阵、拓宽冶炼平台，实现均降焦比约 3%。详见发明专利 ZL 202310750921.9。 With distribution uniformity improved, the charging matrix can be optimized further and the smelting window widened, cutting coke rate by about 3%. See invention patent ZL 202310750921.9
降低物料撞击能耗、提高溜槽中后段物料通过速度，减少物料破碎、降低物料水平速度、提高布料精度。详见发明专利 ZL 202111300814.3。 Reduces impact energy loss and speeds material through the mid and rear sections, limiting degradation, lowering horizontal velocity and improving placement accuracy. See invention patent ZL 202111300814.3
耐磨材料与钢基基体冶金结合后，在高温下具备不易脱落的特性。同时保留可修复性：中低合金基体可用 DSYH-2000 现场堆焊补强，不必整套下线。高温防变形防烧技术保证耐磨寿命不因结构失效而提前终止——这是我们和"只比硬度"的产品最大的分歧点。 Once metallurgically bonded to the steel substrate, the wear material resists detachment at high temperature — while repairability is preserved: a medium-alloy body accepts on-site DSYH-2000 overlay reinforcement without full removal. Anti-deformation and anti-burn technology ensures wear life is not cut short by structural failure. This is where we differ most from products that compete on hardness alone.
