1 FAST-Tunn Future Advanced Steel Technology for Tunnelling Chief scientist/professor Eivind Grøv, SINTEF/ NTNU Project manager FAST-Tunn
2 Background
3 Innovative idea The aim is to increase cutter life by 25% Develop cost effective and wear resistant cutter disks for tunnelling in hard rock Combined with anti abrasive measures Develop realistic numerical models for steel/rock interaction, used in design optimization Develop generic knowledge and understanding of interface steel and geological material Introduce Norwegian manufacturing companies to the TBM industry
4 Steering committe FAST-Tunn BMS Norwegian Research Council Project manager WP 7: Project management Frame work: Totally 30 mill NOK 35% Research Council 35% Industrial Partners, mainly Robbins Innovation project Unique value chain in the project Partners: - BASF - Babendererde Eng - BMS Steel - Norw. Railway Auth. - LNS - Robbins - Scana Stål Research partners: - NTNU - SINTEF WP 1: Basic models and charateization of steel and rock WP 2: Numerical modelling WP 3: Development of steel qualities WP 4: Empircal prognosis models WP 5: Fieldtesting WP 6: Introduction of anti abrasive foam WP 8: Data collection and processing Goal: 25% increased cutter life
5 What makes FAST-Tunn unique? FAST-Tunn includes the entire value chain in TBMtunnelling: Research and academia Steel suppliers and manufacturers Foam supplier TBM-supplier Monitoring developer Contractor Owner Small scale laboratories (drillability&tribology) theoretical and numerical approach scaled testing prognosis analysis full scale TBM-sites
6 Technology in brief An efficient cutter disk should have a hard surface (to reduce wear) and a ductile bulk (to reduce spalling) Starting point for alloy development was a work-hardening cast alloy, currently used in rock crushing machines, The surface of this alloy will harden during use, and continue to harden as cutter is worn Numerical simulations was employed in order to optimize the design of the cutter. Rock fracturing, steel wear, hardening, fatigue, and temperature were considered.
7 R&D Challenges Characterize and test steel/rock interaction Develop a cost-effective manufacturing process Highly complex numerical models are required to model steel degradation and rock fracturing. Establishing a link between numerical simulations and NTNU Prognosis Model. Match the findings with various laboratory testing at NTNU/SINTEF drillability laboratory
8 R&D Challenges Further develop the NTNU Prognosis Model and accompanying laboratory tests OUTPUT FROM PROGNOSIS MODEL Net penetration [m/h] Weekly performance [m/week] Utilization Cost [NOK/m] Lifetime cutter ring Lifetime cutter bearing and hub
9 WP 1, WP 2 and WP 3 Casted and tested 7 different alloys including the most common one in use to day Numerically model and understand the breaking mechanism in both steel and rock Developed new testing methods and even a prognosis model for cutter wear
10 WP 5, Field testing SBU Støren, 6,5 inches test cutters Full scale testing of best steel at AMR in India Linear cutter testing in Korea
11 WP 6, Anti Abrasive foam Important part of the project to test Anti Abrasive foam Initial tests were done at AMR in India Tests were done using Anti Abrasive foam in lab test
12 WP 8 Data collection and processing Early in the project it was found that field testing could only be performed successfully if a data collection and processing system to handle the comprehensive amount of data was employed. Consequently, TPC Tunnelsoft, a member of Babendererde Engineers GmbH joined FAST-Tunn
13 PhD-candidates
14 " Mechanical properties of geological material influencing abrasion of cutter steel for TBM-boring " Supervisor: Eivind Grøv Co-supevisor: Charlie Li Main goal Identify an economical and practial way to analyze the impact of the cutters to: Demonstrate how the rock breaking takes place underneath the cutters Identify the impact of cutter-related or operational changes produce
15 " Mechanical properties of geological material influencing abrasion of cutter steel for TBM-boring " Used samples from AMR in India and Røssåga in Norway Samples taken from different combinations of geology and operating modes of the TBM Great advantage to use samples from one TBM which is encountering different geology Comprehensive mapping is needed to have a baseline of local structures
16 "Numerical modeling of rock breaking in hard rock in TBM tunneling" Supervisor: Amund Bruland Main goal: To include rock breaking in a numerical model
17 "Estimation of TBM Performance and Tool Life" Supervisor: Amund Bruland Co-supervisor: Eivind Grøv Main goal: To update the NTNU Prognosis Modell.
18 What did we achieve? Developed a new numerical tool to estimate cutter wear Tested and compared characteristics of 7 alloys Developed new small scale laboratory testing apparatus PhD-candidates have achievements they will report themselves so that they can take credits of their work One steel alloy is unprecedented amongst the others Further testing is required for the casting method Anti abrasive foam has an impact, not able to quantify properly Did we fulfil our goal to obtain 25% increase? Difficult to say!
19 Thank you!
