Introduction

At steel slab casting facilities, Lechler is widely known for precision air mist and hydraulic spray nozzles used in the secondary cooling process. However, nozzle performance depends on more than the nozzle itself. The reliability of the full spray package also depends on the fabricated components that feed, support, and distribute the spray system throughout the caster.

In addition to nozzles, Lechler can manufacture spray headers, manifolds, distributor pipes, hoses, and spare segment assemblies at production scale. For mill designers and project teams, that means one supplier can support a broader portion of the package from engineered spray components to fabricated hardware, helping simplify procurement while maintaining alignment to specification.

Challenges and Opportunities

Greenfield steelmaking projects and caster expansions create substantial demand for both original equipment and startup spare inventory. The challenge is not simply finding fabricators. It is finding suppliers that can take on a large, technically specific scope and execute it reliably, without creating unnecessary delays, substitutions, or coordination burdens for the customer.

In this case, Lechler was initially discussing nozzle supply for a major new steelmaking facility capable of casting 3.1 million tons per year. During those conversations, Lechler shared that spare caster segment sets could also be supplied. The mill designer needed three sets of both fixed-side and loose-side spare segments for each of the caster's 15 segments and was concerned about finding a supplier with the capacity and discipline to handle the full scope. Splitting the work among multiple suppliers would have introduced added interfaces, more administrative complexity, and more execution risk.

Solution

In recent years, Lechler has expanded its global manufacturing and fabrication capabilities to execute projects like this with greater consistency and control. When customers provide drawings and bills of material, Lechler's purchasing managers and engineers review each item and material in detail, verifying fabrication requirements before building a proposal.

Because Lechler combines in-house manufacturing with a global sourcing network, products can be quoted precisely to customer specification, almost always without part or material substitution. That exact-spec approach helps streamline the process for the customer during both quoting and manufacturing, with minimal back and forth required. Once the proposal is approved, production moves directly into Lechler manufacturing and quality review. The process is straightforward: the customer supplies the drawings, and Lechler delivers the finished product.

Outcomes and Evaluation

Through continued investment in manufacturing capabilities and by adhering to both customer specifications and rigorous internal standards, Lechler is able to deliver large-scale solutions in a timely manner. For the mill designer, that meant sourcing a coordinated package from one trusted supplier instead of managing multiple fabrication sources for a tightly defined scope.

Feedback on the casting segment order, including nozzles, reflected both product quality and execution discipline. The mill designer noted that Lechler supplied a competitive product with exceptional quality and that the attention to detail was evident even in labeling and packaging. That positive experience led to repeat business, as Lechler has continued to supply spare caster segments to this customer and to others.

Lechler's capabilities extend well beyond the caster. The company delivers complete spray solutions across the steelmaking process, including blast furnaces, electric arc furnaces, hot and cold rolling mills, galvanizing lines, pickling lines, and more. For mill designers seeking fewer handoffs and more accountability, Lechler offers more than nozzles. It offers a broader fabricated spray solution backed by engineering, manufacturing, and execution at scale.
