Customized Metal Strips Cold Rolling Mill Lines
Metal strips in pieces or coils come from hot rolling mills and then cold rolling mills, annealing often joins in to soften the metal strips when the strips become too hard, the finished metal sheet product requires a complete process of rolling and annealing, the technology comes from metal material properties and actual production experiences.
Our company is in industrial cluster of metallurgical machinery, easy to outsource required parts, therefore we can supply good metal strip cold rolling mills at competitive prices. Our engineers work in the metal strip rolling industry for tens of years, can provide consultation of installation, commissioning and maintenance technology. Welcome you to inquire us!
Our metal strip cold rolling mills are specially designed as per customer requirements,
1. metal sheet materials: plain carbon steel, stainless steel, high quality steel, aluminium, copper, brass, nickel, titanium alloy, etc..
2. The incoming metal sheet specification: strip width, strip thickness, strip coil weight
3. The finished metal sheet specification: finished thickness, thickness tolerance, flatness tolerance
4. Capacity of the cold mill: yearly production (how many tons per year for average thickness)
5. Configuration of the cold mill: automatic gauge control or not?
The most popular cold mills we supply is 4 hi, 6hi, for the reasons:
1/ 4 high, 6high cold rolling mills are suitable for most applications of metal strips product, can reach the required product precision
2/ operation and maintenance of 4 high, 6 high cold mills is not so complicated, operator can handle after training of certain time.
3. Rollers changing are not so much as more complicated mills.
4. 4hi 6hi cold rolling mills are durable.
5. 4high 6high mills can provide various thicknesses of cold rolled strips.
We supply different models of 4hi 6hi cold mills to customers, look forward to cooperate with you.
