Hydraulic Scrap Shearing Machine for Steel Mill Furnace Charge Preparation

Meta Description

Hydraulic scrap shearing machine for steel mill furnace charge preparation. Designed to cut oversized scrap steel into manageable sizes with 700 ton shearing capacity and hydraulic pusher feeding.

Product Overview

In steel mills and EAF steelmaking plants, scrap size control is important before furnace charging. Oversized or irregular scrap steel can affect feeding, handling and furnace loading workflow.

The Q91Y-700W hydraulic scrap shearing machine is designed to cut heavy scrap steel into shorter sections for furnace charge preparation. With a 700 ton shearing capacity, twin 3500KN shearing cylinders and a 7500 mm feeding box, it can process steel plates, round steel, square steel and other ferrous scrap within the specified material range.

This machine is suitable for steel plants, scrap processing centers and recycling companies supplying prepared scrap to steel mills.

Key Features

Scrap Size Reduction Before Furnace Charging

The machine helps reduce oversized steel scrap into shorter sections, making it easier to handle, transport and prepare for furnace charging.

1600 mm Blade Length

The 1600 mm blade length supports cutting of wider scrap sections, including steel plate scrap and structural steel pieces within the stated cutting range.

Hydraulic Pusher Feeding

The machine uses a YG220/160 push cylinder with 7500 mm stroke and 1000KN full thrust.

This supports step-by-step feeding from the box toward the cutting area.

Cover Pressing and Clamping

The Q91Y-700W combines three cover cylinders and two clamping cylinders to help control bulky scrap before shearing.

Technical Specifications

Cutting Range for Furnace Charge Preparation

The Q91Y-700W is suitable for materials with Δb≤450 MPa.

These values help steel mill buyers evaluate whether the machine matches their common incoming scrap types.

Suitable Steel Mill Applications

This machine can be used for:

• EAF scrap preparation
• Furnace charge size reduction
• Heavy scrap steel cutting
• Steel plate offcut processing
• Prepared scrap production
• Recycling plant to steel mill supply chain

Buyer Selection Notes

Before purchasing a scrap shearing machine for steel mill preparation, buyers should confirm:

• Common scrap material type
• Required charging size
• Maximum scrap thickness
• Material strength
• Feeding method at site
• Cooling water availability
• Power supply conditions
• Installation space and foundation layout

FAQ About Scrap Shearing Machine for Steel Mill

Q1: Why do steel mills need scrap shearing before furnace charging?

Steel mills often need scrap with manageable size for easier loading and furnace charging. Oversized, long or irregular scrap may require cutting before entering the melting process.

Q2: Is the Q91Y-700W suitable for EAF steelmaking scrap preparation?

Yes, it can be used for EAF scrap preparation if the scrap material is within the specified range. The machine is designed with 700 tons shearing capacity, 1600 mm blade length, and a 7500×1600×800 mm feeding box.

Q3: What cutting range is useful for steel mill buyers?

For steel mill scrap preparation, the key cutting data includes round steel up to φ140 mm, square steel up to 110×110 mm, and steel plate up to 70×500 mm, under the material condition of Δb≤450 MPa.

Q4: How does this machine support furnace charge size reduction?

The machine receives scrap in the feeding box, presses or clamps the material, pushes it toward the shear opening, and cuts it into shorter sections. This process helps prepare oversized scrap for handling, transportation and furnace charging.

Q5: What should a steel mill confirm before ordering?

A steel mill should confirm maximum scrap size, steel grade, material strength, desired final scrap length, feeding method, site layout, power supply and cooling water availability.
