Process Flow

Continuous Cast copper Rods Plant – CC Rod Technology – Southwire , USA Installed Capacity : 80, 000 TPA • • • Refined Copper Cathode is transformed into Continuous Cast Copper Rod in the CC Rod plant for higher value addition. Continuous cast copper rods of 8, 11, 12. 5, 16 and 19 mm diameters are produced to cater to the needs of a wide customer range. The rods hence produced undergo on-line defectomat scanning to International Quality Standard (ASTM B/49/92

PROJECT DETAILS START DATE : - 30. 07. 2004 FINISH DATE : - 30. 11. 2004 NO. OF MEETINGS : 16 MEETING DURATION : 30 MIN (EVERY MONDAY) IMPACT OF THE IMPROVEMENT ØIMPROVED CAST BAR STRUCTURE. ØREDUCTION IN LUMP FORMATION. ØREDUCED REJECTION AND RECYCLE.

REASONS FOR PROJECT SELECTION OF THE PROJECT REJECTION ON THE GROUND OF SPOUT CLEANING SOLIDIFIED LUMPS NEAR SPOUT HEAVY SPLASHING

WHY SELECTION ü PRODUCTIVITY LOSS. üDETERIORATION OF QUALITY üVALUE LOSS. üCUSTOMER COMPLAINT

SPLASHING EFFECTS ON THE PROCESS : Lump formation near spout because of metal splashing. Lump cleaning leads to rejection of coil. Metal splashing leads to oxide inclusions in cast bar.

METHODOLOGY FOLLOWED ROOT CAUSE IDENTIFICATION & TOOLS AND TECHNIQUES USED (01) WHY-WHY ANALYSIS was carried out simultaneously to arrive at specific conclusion for high risk factors. (02) ACTION PLAN was drawn on the basis of Analysis and Improvement Plan & IMPLEMENTED subsequently. (03) Sustenance of IMPROVED PRACTICES

DATA SOURCE (1) Shift Engineers’ Log Book. (2) Coil wise / Parameter wise Inspection Report. (3) Casting operators logbook. v Meetings were held once on weekly basis among the team members to find a solution. v Brainstorming + creative thinking were undertaken along with Gemba investigation in order to solve the problem.

WHY-WHY ANALYSIS Metal Splashing Why ? Off centered metal flow from pouring spout Why ? Improper centering of Tundish on casting Machine Why ? Visual judgment error Why ? No tool for precision centering CONCLUSION (01) Some tool has to be designed to eliminate human error in centering

ACTIONS TAKEN No. ACTIONS TAKEN – AT A GLANCE 1 Study of location of pool position 2 An in-house template designed 3 Trial taken. 4 Operators trained to do centering with help of template

RESULTS AFTER USE OF TEMPLATE NO LUMP EVEN AFTER 48 Hrs of Operation

COST OF PROJECT TOTAL PROJECT COST (MATERIAL COST + MANPOWER COST) Rs. 200

COST DUE TO SPOUT CLEANING Estimated Cost Element Cost / MT 1. PROPANE Rs. 870 / MT 2. POWER Rs. 225 / MT 3. IPA Rs. 60 / MT 4. CONSUMBLES Rs. 320 / MT 5. OTHERS Rs. 175 / MT Recycle Cost for rejected material Rs. 1650 / MT

ADVANTAGES LOW SPLASHING IN METAL POOL NO LUMP FORMATION NEAR SPOUT NO REJECTION DUE TO SPOUTCLEANING REDUCED RECYCLE LOAD HIGHER PRODUCTIVITY

RESULTS

BENEFITS TANGIBLE BENEFITS : SAVING : Average Reduction in recycle load from 9 Kg. /MT to 3 Kg/MT i. e. 6. 0 Kg/MT. Actual SAVINGS : Considering Annual CCR production during 2003 -04 : 91, 848 MT It turns out to be 551 MT per Annum 551 * 1650 Rs. /MT = Rs. 9, 09, 150/Potential SAVINGS : Considering Annual CCR production capacity of 1, 20, 000 MT It turns out to be 720 MT per Annum 551 * 1650 Rs. /MT = Rs. 11, 88, 000/-

BENEFITS INTANGIBLE BENEFITS: § Improved casting control. § Better product quality and consistency. § Eliminating unsafe working condition. § Increased team bonding and motivation levels.
