Dam Rings

Overview

Contact our sales partner

The IMCO Dam rings are made with completely replaceable segments. Previous solutions of welding worn out areas is time consuming and not cost effective at all. Our solution enables replacing worn out sections of the dam ring within two hours. This helps reduce downtime, increase efficiency and save money.

Result of Support/Dam Ring:

Power Consumption- 1.5 kwh/ton
Return of Investment- Less than 6 Months
Optimization still in process

Features :

Extremely high abrasion and erosion wear resistance offered by Zuper Metal matrix composite carbides block segmental design.
Consistent Hardness & Micro-structure across thickness results in consistent & unmatched wear rates
Process ensures extremely low residual stresses
Packed & Uniform Distribution of superior Hexagonal primary carbides improving wear resistance
Gap between support ring and grinding rolls can be maintained by providing higher thickness of Zuper metal matrix composite carbides layer.
Highly cost effective solution.
Hardness : 58-62 Hrc
Reduces downtime losses.

Saving Head	Existing Solutions	IMCO solution	Remarks
Replacement time per mill	5-6 days	1 day (Max)	Shut down time reduced by 80% Productivity increased Mill uptime increased
Resources required	Crane required	Only simple tools required	Imco Zuper block segments held by nuts and bolt arrangements. Only simple tools required to change segments.
Hardfacing required	IN 3-4 weeks	No hardfacing	Imco solutions does not require any hard facing having an excellent Zuper metal matrix composite carbide metallurgy to withstand very high abrasion and erosion wear.
Man power	2-3 person or more	1 person (max)	Imco replaceable segments have easy assembly and disassembly mechanisms. Only one person can remove or replace the worn out segments
Mill efficiency	Lower (Faster wear rate)	Higher (Uniform properties throughout)	Faster wear rates result in frequent hardfacing which causes higher stresses induced in base material and frequent shutdown periods. In case of IMCO solution, having a lower rate of wear which indirectly increases efficiency and lowers the power consumption considerably.
