Rear-Push Hydraulic Scrap Shear with Adjustable Cutting Length for Furnace Feed Preparation

SEO Title: Rear-Push Hydraulic Scrap Shear with Adjustable Cutting Length
Meta Description: The Q91Y-630W hydraulic scrap shear uses a 135-ton rear pusher, 7000mm stroke, and adjustable length control to prepare steel scrap for furnace charging.

Controlled Scrap Feeding Instead of Repeated Manual Positioning

The Q91Y-630W rear-push hydraulic scrap shear is designed for recycling facilities that need to cut long steel scrap into more manageable sections. Its main feature is a hydraulic pushing system that moves material through the feed box and toward the cutting chamber.

The rear pusher uses a YG220/160-7000 hydraulic cylinder with a 7000mm stroke. Its maximum thrust is 1350kN, equivalent to approximately 135 tons, while the documented pushing speed is 300mm per second.

This arrangement is particularly useful when long steel sections must be cut repeatedly. Instead of repositioning every piece manually after each cycle, the hydraulic cylinder advances the remaining material according to the selected feeding distance.

Adjustable Cutting Length for Different Requirements

The machine includes a material-length control system. Operators can adjust the feeding distance according to the required output size.

Shorter cut sections may be preferred when scrap is prepared for:

• Electric arc furnace charging
• Induction furnace feeding
• Foundry material preparation
• Container loading
• Internal plant transportation
• Compact yard storage

Longer sections may be acceptable when the main purpose is reducing the original scrap length before transport.

The final cut length can be influenced by material shape, loading position, surface condition, and the accuracy of the feeding setup. The system provides adjustable control, but it should not be described as a precision metal-cutting system for finished parts.

Suitable Long Scrap Materials

The rear-push design can be applied to various heavy ferrous materials, including:

• Long steel plate offcuts
• Structural steel remnants
• Round-bar production ends
• Square steel scrap
• Fabrication workshop waste
• Demolition steel sections
• Steel mill production rejects

The internal feed box measures 7000 × 1600 × 900mm, allowing longer materials to be loaded before being gradually advanced toward the blade.

Hydraulic Holding Before Each Cut

Once the material reaches the cutting position, two holding cylinders press it before shearing.

Each holding cylinder provides approximately 80 tons of force, producing a combined holding force of about 160 tons. This helps stabilize stacked, bent, or irregular steel scrap before the blade enters the material.

Main Parameters

Why Use a Rear-Push Scrap Shear?

A rear-push hydraulic shear is suitable when scrap arrives in long and inconsistent sizes. It helps organize material movement through the machine and reduces repeated crane repositioning during multi-cut processing.

For accurate machine selection, customers should provide the maximum incoming material length, cross-section, steel grade, required final cut length, and expected hourly capacity.
