Metallurgical engineering and equipment supplier within the Dalian Dashan manufacturing group, focused on continuous-casting systems, copper mould components and caster upgrades. The published range connects replacement mould tubes and plates with assemblies, withdrawal equipment, dummy bars and project engineering.
What the published manufacturing scope means for a buyer.
DDMET identifies Dalian Dashan Metallurgical Engineering Technology Co., Ltd. as the group's research and design center established in 2007. The company history separately dates the crystallizer manufacturing business to 1992 and describes later coating, heavy-machinery and copper-processing businesses. This distinction matters: a buyer should identify the contracting company and the responsible manufacturing site for each package, rather than assume the engineering office performs every process. Its strongest documented focus is continuous casting, where existing machine geometry, cooling arrangements, material and coating choices connect the component order to the operating caster. [1] [3]
The catalogue spans tubes and plates, mould assemblies, oscillators, withdrawal/straightening units and dummy-bar systems. This creates a useful engineering conversation when replacement components must fit an existing caster, or when a change affects several connected assemblies. [6]
The factory page describes pressing, machining, electroplating and fabrication equipment, with captioned hydraulic-press and machining photographs. The group history also separates coating and copper-processing operations, providing a basis for discussing how material preparation, final geometry and coating are allocated across an order. [2]
A 2016 copper-tube entry gives a 180 × 180 mm section, 1,000 mm overall length and 8,000 mm radius for a Pakistan application. Other entries identify a 2019 Indonesia slab-mould/oscillator project and a 2013 Thailand caster revamp. These supplier-published records illustrate the type of work; they are not current stock or independent customer endorsements. [4]
CNFX synthesis of the company’s published information.
The core distinction is between a drawing-controlled replacement part, a complete assembly and an engineering modification to the caster.
Square, round and other section families appear in the catalogue. The 180 × 180 mm example records length, caster radius and a DHP-Cr material/coating notation. An enquiry should preserve the drawing's taper, corner radii, mounting details and cooling interfaces rather than specify only the nominal billet section. [4]
The plate page lists conventional, CSP, fTSC and beam-blank formats, with CuAg and CuCrZr materials and several coating descriptions. Its dated example is a 2,266 × 900 × 45 mm wide plate. Treat material, coating system, water-channel geometry and repair requirements as an agreed configuration, not interchangeable catalogue options. [5]
Published examples include billet assemblies and a slab-mould assembly with hydraulic oscillator. Define the mechanical envelope, mounting interfaces, water connections and required oscillation functions at assembly level; a matching copper insert alone does not establish a complete interchangeable assembly. [6]
The water-cooled withdrawal/straightening page identifies drive, reducer, coupling, rolls, bearings and press-down components. The flexible dummy-bar entry shows a separate chain-type starting system. Both need the caster geometry, section range and interfaces specified before replacement or modification can be evaluated. [8]
DDMET offers complete continuous-casting equipment and upgrades as well as components. Its Thailand revamp entry describes design staff monitoring fabrication. A project enquiry should distinguish design, supplied equipment, control integration, site work and commissioning responsibilities in the scope of supply. [10]
Published processes, organized by production stage.
Provide drawings, cast section, radius, steel grades, speed range and operating problem. Identify whether the order is a like-for-like replacement or a change to the casting process. [4]
Set the copper grade, dimensional tolerances, coating system, cooling passages and inspection plan. For an assembly, include mating components and connection drawings. [5]
Identify the responsible group company or production site for pressing, machining, surface treatment and assembly. Confirm which documents, inspections and fabrication reviews are included in the proposal. [2]
For upgrades, agree interface checks, installation responsibilities, commissioning conditions and acceptance records. Historical project descriptions should lead to a project-specific scope, not an assumed turnkey commitment. [10]
Material identity, finished geometry, coating and assembly interfaces are central to the procurement package. The published website gives manufacturing context, while order-level inspection and current certificates remain documents to request.
The plate range names copper alloys and coating options. Ask for material identification, agreed coating thickness and process, dimensional results and inspection records that identify the supplied part or batch. [5]
Mould assemblies, withdrawal equipment and dummy bars connect to existing mechanical, hydraulic and cooling systems. Agree the relevant fit-up, movement and functional checks with the supplier, using the installation drawings and operating conditions as the acceptance reference. [8]
The company page displays historical ISO 9001:2008-era and QA International certificate images. Obtain a readable current certificate with the applicable holder, production address, scope and validity before treating certification as a purchase qualification. [1]
These are dated entries published by DDMET. They describe the equipment and destination, without establishing present operating results or buyer endorsement.
The August 2016 entry specifies 12 copper mould tubes at 180 × 180 mm, 1,000 mm overall length and R8,000 mm. Its procurement value is the combination of section, length, curvature and material/coating notation rather than the quantity alone. [4]
The July 2019 entry groups the mould assembly with its oscillator. It illustrates an assembly-level supply enquiry where mechanical and hydraulic interfaces should be reviewed together. [7]
The May 2013 record describes a revamp and design personnel monitoring fabrication. It supports discussion of engineering-led modification, but does not publish quantified operating improvements or the full site-service scope. [10]
CNFX procurement assessment.
DDMET is relevant to steel producers and equipment integrators sourcing caster mould components, replacement assemblies or an engineered upgrade. The supplier's group structure and component-to-project range make scope allocation particularly important: define the drawings, material/coating system, manufacturing responsibility and site interfaces before comparing price. The published office and registration addresses should not be substituted for the selected manufacturing site's address.
