Your Speciallist for processing of semi-finished product

Development of Evertz grinding

Before semi-finished steel-made material by rolling or forging can be treated with further processing, certain parts and defects might have to be sparked out. Sometimes a subsequent grinding of the complete surface of slabs and billets is necessary, too. Even in other areas of steel treatment, grinding is often preferred over other surface-treatment procedures.

Our specialization includes the job grinding of slabs, blooms, billets, sheet bars, ingots, etc., achieving the correct quality of surface finish for specifications using axial, radial and cup grinding wheels. Depth of roughness ranging from 160µ to 30µ ispossible, as well as hot grinding, 45° grinding angle and special ground-surface patterns.

It's not a coincidence that we've been able to combine quality and affordability. Evertz integrates the know-how of a grinding-machine producer with the experience of a grinding service. We grind for you - anywhere and anytime!

High pressure Grinding

Before further processing of semi-finished steel products by rolling or forging, it is necessary to grind out defects in some places, but in some cases also to grind the entire surface. In other work on steel products, too, grinding is often given preference over other surface treatment methods.

Our competence: Contract grinding of slabs, blooms, billets, blanks, round material, ... the right surface quality for every surface.

Quality combined with low costs is no accident. EVERTZ combines the know-how of a machine tool manufacturer with the long experience of a grinding service provider.

We grind for you - anywhere, any place.

High pressure Grinding
High pressure Grinding

  • All types of steel including carbon, stainless alloys and other metals such as nickel and titanium.
  • Any steel product - geometries (slabs, blocks, billets, blooms, round products ...)
  • At any angle (usually 45 ° or 90 °)
  • Grinding specifications according to cutomer requirements and the degree of defects to be eliminated (test, point, partial or complete grinding)
  • Surface quality according to customer requirements (usually from 135μ to 30μ)
  • Hot grinding of steel products up to 800 ° C
  • Selective grinding to minimize material loss
  • Advantages compared to scarfing:
    • no gas and oxygen consumption
    • no Co2 emissions
    • no water consumption
    • no introduction of temperatures into temperature-sensitive steel grades
    • significantly lower investment costs and thus lower fixed costs per t for the customer

Grinding at the customer's site

Evertz installs the necessary systems and machines and carries out the grinding work within the customer's factory.

In this case, only the customer's products are processed.

No external transport of the products required.

Volume is needed to justify the capital investment required.

The chips are provided to be returned to the production process.

External grinding centers

Evertz grinding centers: we operate grinding machines at several locations in our own factories

In this case, different customers deliver their products to us for processing

Products must be transported and, as soon as they have been processed, sent back to the customer

A cost-effective solution for smaller volumes

Savings are returned sorted by type.

Quality

With regard to the constant improvement of the slab surface, the following is part of the EVERTZ service:

  • Daily production planning in cooperation with the customer.
  • QA inspection of the slabs before grinding.
  • Grinding of the slabs according to customer specifications with advice from EVERTZ.
  • QA inspection after grinding.
  • If necessary: regrinding to remove remaining defects
  • Labeling of the ground slabs and passing on the information to the customer

Stainless Steel

Example of a Grinding shop

  • Today we grind around 18,000 tons of slabs per month in this grinding shop
  • Ground grades include ferritic, austenitic and martensitic, stainless steel, which are subject to complex grinding programs.
  • Evertz is 100% responsible for all rectification of defects, QA inspections, machine-readable slab labeling and shipping.
  • More than 98.5% of surface defects are removed after the first sanding (the remaining 1.5% are removed after being detected during the inspection)
  • In 2009 we reached the milestone of 1,000,000 tons of ground stainless steel slabs. These 1,000,000 tons “just in time” were achieved WITHOUT any complaint
  • Since EVERTZ took over the grinding work: Reduction of the ´Lamination - Rate´ from over 12% to less than 1%!

Advantages

Your advantages:

  • Fixed costs per t or m2 of steel.
  • No high investment costs for a new grinding system.
  • No expenses for repair and maintenance costs.
  • Determination of the optimal grinding program for maximum surface quality with minimum material loss by EVERTZ employees.
  • Return of the grinding chips (sorted by type on request) into the production process.
  • Compared to scarfing, no approval procedures are required
  • EVERTZ manufactures the required, hot-pressed high-pressure grinding wheels itself and can thus optimally adapt the grinding wheels to the material and the requirements of the customer.

For information:
  • Today Evertz operates over 40 grinding systems worldwide, most of which are in use 24 hours a day, 7 days a week. (24/7)
