Sand Reclamation & Automation Implications & Applications for Foundry 4.0

Presented by Manish Kothari - Rhino Machines, Anand, Gujarat

Foundry 4.0 = SMART Foundry

The first thing to understand about Industry 4.0 is it is not one technology but a combination of modern technologies combined to create a ‘SMART factory’.

by Mark Lewis at the World Foundry Congress in Nagoya, Japan in May 2016.

Before we make the Foundry SMART…we must understand what goes into making a Casting – the business of the foundry itself, and then see how we can move to a SMART Foundry

SMART Foundry – How?

The key elements required to make the Foundry SMART Process automation – most challenging Machine automation – most common, needs process integration Machine learning – very critical for foundry 4.0 Systems automation – Change to Demand based systems Upskilling Human Resources – key to success of Foundry 4.0 12-Mar-18

Green Sand Process – Variables at Macro Level Sand Preparation

Moulding Machine

• Control and Consistency in Instantaneous properties • Logging of all inputs to the sand preparation e.g. return sand, new sand, bentonite, coal dust, water, temperature..etc

• Control of Mould Quality & Consistency • Recording of process parameters for each mould and casting • Monitoring and control of mould and casting rejection in realtime • Production capacity and availability

Return Sand System • Management of System sand properties • Control of Sand Temperature • Control of Silica Content, AFS, Clay, VM, LOI in sand, Grain Shape • Relation of Defect with Sand properties

12-Mar-18

Waste Sand • Controlling Waste at Knock out, Shot Blast, Dust Collector, Screen, etc • Excess Sand disposal validation • Sand reclamation & recovery integration Copyright - Rhino Machines Pvt Ltd

Casting Data • Relation of Rejection with Mould • Validation and control of cooling time • Establishing relationship between sand, mould and casting rejection in realtime 6

Data Acquisition & Data Analytics being done – User Interface under preparation • Moulding production data – hour, shift, day, week and any period • Energy consumption per mould, per kg casting • Casting moulding and production analysis • Mould rejection analysis • Asset maintenance – alarms, preventive maintenance, predictive maintenance analytics 9

IIOT in Green Sand Process – deliverables in Foundry 4.0

Green Sand Plant – Sand Preparation • With intelligence of software, and remote access of data in realtime, the supervisor does not have to go to the wired connection to check the information • Data is PUSHED, and has not to be pulled…saves time for finding the faults and deviations • Data is interfaced with Resource planning softwares – allows consumption monitoring in realtime instead of manual process • Production Shops comparative is created – sand produced v/s mould produced v/s casting poured brings out the efficiencies and losses at different shop interfaces – no more a blame game….purely data based systems 12-Mar-18

Rhino Sand Reclamation Project – Foundry 4.0 Relevance

Core Making

S1

• Control on Core Quality, Resin Consumption • Known processing cost, reduced variables in predicting costs

S2

S3

Moulding Sand Preparation

• No availability issues, reduced variances in process • Predictable process control in sand preparation process

Logistics & Work in Process

• Reduction in 60 to 80% of procurement with integrated sand reclamation plant • Reduced Storage, inventory management = better logistics and space management

Core Sand Reclamation

Plant summary

Copyright - Rhino Machines Pvt Ltd

• • • •

Area Occupied – 540 m2 : Storage – in Silos Floor losses & handling – nil Waste disposal – 60%-70% reduced • Processing 50 MT/day 12 • Process Cost – Rs 2.25/kg

IIOT in Sand Reclamation – deliverables in Foundry 4.0

Sand Reclamation • With PUSH Data systems – critical control of system w.r.t. temperature, consumptions of gas or energy, alarms does not need 24 x 7 vigilance or person.

• Realtime production data possible, no manual checking of weights…combination of machine data acquisition, cloud and analytics make time available for productive work • Post production analysis helps evaluate the process from anywhere, provides process expert support at any time from anywhere…an advantage which can be leveraged with IIoT in creating stable & sustainable systems.
