Parts stable on the hearth
Define the loaded centre of gravity, supports and envelope, including clearance through the chamber opening.
ELEVATOR HEARTH FURNACE
For parts, baskets and fixtures that can rest stably on a hearth. Confirm the load envelope, total supported weight and building clearance before defining lift travel, opening seals and heating conditions.
Configuration and acceptance conditions are agreed for each project.
Match the workpiece, loading method and production rhythm before choosing the furnace arrangement.
Define the loaded centre of gravity, supports and envelope, including clearance through the chamber opening.
Include baskets and fixtures in the supported weight and assess access and hot stability.
Compare building clearance and transfer routes first. Rapid quenching requires separate assessment of structure and equipment.
This page covers a lift-bottom arrangement. Parts, baskets and fixtures must be stable on the hearth and fit its clearance, total load and handling limits. Rapid quenching requires a separate assessment of structure and transfer route.
These are design inputs. Select and verify the final arrangement against the actual process.
This design has a fixed upper chamber and a moving bottom hearth. A lifting chamber has different moving parts and interfaces.
Assess parts, baskets, fixtures and moving support components separately; part weight alone does not size the lift.
Allow for lift travel, opening clearance, lifting access, maintenance and reliable support in addition to the load envelope.
Atmosphere duty needs specified seals, purging, monitoring and acceptance; appearance or hearth closure does not prove gas-tightness.
Elevating furnaces have multiple configurations. This page describes a lift-bottom arrangement. Load, stroke, sealing and safety interlocks require project assessment.
Confirm clear building height, lift travel, loading area, foundation or pit requirements, maintenance access and lifting arrangements. Specify the unloading temperature condition and any cooling or transfer method.
Use the illustration to discuss equipment interfaces. Final details follow the agreed design.
Check parts, baskets, fixtures and required clearances together.
Include parts, fixtures and moving support components, with uneven loading defined.
Allow separately for loading, lift travel, lifting access and maintenance.
Confirm temperature, cycle, atmosphere and hearth closure conditions.
Specify operational guarding, the power-loss state and maintenance support separately.
Columns support the fixed upper chamber; the lower hearth raises the load into the heated space.
The section shows hot face and backing; check thermal cycling and structural clearances for the process.
Elements surround the working zone and stay clear of the load and hearth movement.
The upper chamber is open below; the loaded hearth rises into it and closes the opening. The front is sectioned to expose the entry path.
Check lift travel, guides and position sensing against total load, centre of gravity and uneven loading.
Include fixtures in the envelope and total load; parts must remain stable when hot and during lifting.
Lower the hearth to load, verify chamber clearance, then raise and seal it for heating. Complete the specified cooling or transfer preparation before lowering it to unload.
Elevating furnaces have different arrangements. This page shows a moving bottom hearth entering a fixed upper chamber; establish that distinction before specification.
Include baskets, fixtures and moving support components, with centre of gravity, uneven loading and hot conditions defined in the specification.
Assess the material, permitted transfer time, hearth movement and cooling-equipment position separately. A bottom-loading design alone does not establish rapid-quench capability.
Measure building height, hearth loading area, lifting route and foundations, then account for travel, maintenance and support space.
