在极端环境下运行

烧结矿破碎机
CIMG1521

在钢铁厂中,在高温下处理烧结矿的设备会遭受严重的磨损。尤其需要确保对高吞吐量的烧结破碎机提供磨损保护,以避免昂贵的维护费用和频繁的工厂停工。维护负责人普遍认为市场上所提供的标准解决方案不足以满足他们的需求。转子和断路器条必须定期换新。
标准解决方案所提供的耐磨性不足的原因主要有三点:

• 烧结矿的高温降低了耐磨堆焊性能;
• 烧结矿较为粗糙,将磨损部件;
• 高冲击力将对脆性耐磨堆焊造成破坏。

MADE BY LASER CLADDING

Sieves manufactured in our workshops
20160905_122630

We offer a comprehensive range of wear-resistant sieves with round, square or oval apertures manufactured from 3 mm thick or higher, perforated sheets. We also manufacture tailor-made solutions according to specific customer requests. Our production technology uses a state-of-the-art, high power laser cladding installation. This system ensures highest quality wearfacing coatings of tungsten carbides dispersed in a nickel-based matrix to protect standard perforated steel sheets with variable mesh sizes.

Much better than standard steel

Tailor-made for your needs

The ultra hard tungsten carbide phases which are homogeneously distributed within a self-fluxing, tough nickel-based alloy matrix, provide:

  • Extreme wear resistance performance against abrasion and erosion up to 10 times higher than standard, monolithic heat-treated steel alternatives.
  • Withstands operating service temperatures up to 400°C. For even higher service temperature requirements, a diverse range of special alloy systems may be proposed to meet specific customer needs.

Modern Castolin Eutectic LaserClad technology uses a focused laser beam to ensure low heat input welding conditions, which translates into extremely effective, wear protective coatings on industrial parts.

Feeding Roller
05 4666 TM_2

After mixing the raw materials in the sinter plants (fine iron ores, additives such as limestone and olivine, recycled iron-bearing materials  from downstream operations, and coke breeze) we find a roller just underneath the charging system to constantly feed the sinter belt which is affected by abrasion. The lifetime of this feeding roller can be increased by our turnkey solutions.

Sinter Cooler
Picture 1

In most cases after the sinter discharge, crushing and hot screening, the sintered material proceeds to a separate cooler. This is typically a rotating structure, divided into circular sectors with tipping devices, in which the sinter is placed in a layer more than 1 m thick and cooled by fresh air.

When the sinter has completed the cooling cycle, each sector is emptied via the tipping device. The cooled sinter is transferred to screens that separate the pieces to be used in the blast furnace.

Both the charge and discharge of the cooler deteriorate the surfaces whose lifetime can be increased with our CDP® wearplates.

Cooling the steel is a critical factor

Air Suction System

Along the whole sinter process, several metallurgical and chemical reactions take place which produce dust and gaseous emissions apart from the sinter itself. These gases contain particles such as heavy metals that will weaken the inner surface of air suction systems.

A complete high resistance conduction system including valves and transitions circular to square section can be manufactured with our CDP® wearplates.
