Mandrel Mill Process. In the Mandrel Mill pipe manufacturing process, the steel billet is heated to high temperature in the rotary furnace. A cylindrical hollow, which is also known as mother hollow, is produced with the help of a rotary piercer and set of roller arrangement that keeps the piercer at the center of the billet.

MO-RE® 1 is a good option for use in severe high temperature furnace roll and radiant tube applications. MO-RE® 2 : 0.20: 33: 50: W 17+Al: Exceptional strength and oxidation resistance to 2400° F (1315° C).

These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils.

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

Nov 05, 2010· Alter exiting the furnace, the skelp edges are heated to welding temperature, generally with an oxy-acetylene burner. The skelp is then passed through welding rolls which form the tube and squeeze the hot edges together to make a solid weld. Sizing rolls correct pipe diameter before saws cut it to length.

on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H.

Apr 01, 2015· The rolls of F#5 stand of the Thin Slab Caster Rolling (TSCR) mill failed during operation. Visual observation of the failed component is shown in Fig. 2a–c which indicates that the fracture line had initiated from the outside and spread over the whole cross section starting from the filet area. The closer view of the fracture surface showed ratchet marks on the periphery of neck portion.

Dry rolls minimize heat loss in the furnace, reducing energy consumption. Duraloy's proprietary MO-RE 2150® alloy has allowed furnace operators to retrofit entire furnaces with dry rolls. Water Cooled Tunnel Furnace Roll Assemblies. Water cooled rolls are found in CSP tunnel furnaces …
