WhatsApp: +86 18838072829Tube mills are welded roll form systems that have been finetuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product. Progressive male and roller dies (or rolls) shape the incoming strip for welding a specific diameter.
WhatsApp: +86 18838072829Tworoller mills Tworoller mills are the simplest variety, in which the material is crushed between two rollers before it continues on to its final destination. The spacing between these two rollers can be adjusted by the operator. Thinner spacing usually leads to that material being crushed into smaller pieces.

WhatsApp: +86 18838072829I think the first roller crushes at about .70 and the second at .39 or whatever. It's basically like a double pass thru the mill at once. I have heard that it negates the benefits of conditioning, too. Nope, conditioning still makes a big difference for a 3 roller mill. I actually still double crush mine with a 3 roller mill.

WhatsApp: +86 18838072829Because of the current demands on mills to process much lighter exit gauges from increased incoming hot strip thickness, much larger reductions are necessary on individual mill stands, such high reductions at a nominal width result in a larger area of contact with corresponding higher rolling force, friction and heat generation (see Fig 1
WhatsApp: +86 18838072829Some rolling processes use two rollers, whereas others use four or more rollers. Regardless, as the steel passes through the rollers, it develops a uniform thickness and consistency. To perform rolling, though, steelmaking companies often rely on a rolling mill. ... Rolling mills work by using multiple rollers to manipulate the physical ...
WhatsApp: +86 18838072829If one roller is rotating with N speed and the other is rotating with N1 speed, then we will get incomplete compression of the roller. Therefore, it is recommended to use the same speed for both the rollers. Types of Rolling Mills: Metal Rolling is classified into 5 types and they are as follows. Two High Rolling Mills; Three High Rolling Mills

WhatsApp: +86 18838072829In four high rolling mills, there are four rollers rolls in the opposite direction. Two rollers, each are placed on both sides of the metal sheet. Unlike three high roller mills, the metal sheet will pass through only once. If you want to further reduce the sheet thickness, you need to take out the sheet from the machine and feed it again.

WhatsApp: +86 18838072829It consists of three rollers, with one roller moving above and between the other two. The rollers are made of cast iron, corrugated or grooved in various patterns. A feed filling mechanism provides the necessary force to allow the feed to pass through the first pair of rollers, either by the use of a small mill opening or a high rate of feed.
WhatsApp: +86 18838072829Rolling is the most important metal forming process. More than 95% of ferrous and nonferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. and Fig.
WhatsApp: +86 18838072829Normally there are two or three furnaces. Each furnace is equipped with a charging and discharging device. A mathematical model is used to control the burners to achieve the optimum reheating curve for each steel grade.
