Base on the plentiful experience of producing and marketing of impact crusher, Birnith R&D institution designed the PFW series impact crusher. It is the newest style impact crusher and has been widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
By absorbing the advanced technology from the world, we researched and designed PF series impact crusher. It can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa. Thus, it is widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
PEW series Jaw crusher features big crushing ratio, reliable operation, easy maintenance and low operating cost. It is the new generation product designed and produced by Birnith, basing on our 30 year’s crusher production experience and the latest design conception. It does be one high efficiency and low cost crushing machine.
PE series jaw crusher is usually used as primary crusher in quarry production lines, mineral ore crushing plants and powder making plants. It can be described as obbligato machine in mining, building construction, construction wastes crushing, Hydropower and Water Resource, railway and highway construction and some other industries.
MTM Medium Speed Trapezium grinder is a kind of leading-world-level industrial milling machinery.

The No. 3 Cold Strip - East Mill at Inland Steel cold rolls steel for use in auto bodies, refrigerators, and other familiar products. The cold-reduced steel is made by cold rolling previously hot-rolled steel which is in long, thin sheets wrapped into a coil. The coils of steel are
Cold Mill. Application Overview. Overheating steel as it is rolled affects the mechanical and dimensional properties of the steel and causes surface blemishes. Pyrometers are used to make sure the steel does not get too hot. Williamson Wavelength Advantage.

The hot working of P- containing silicon steel is not difficult, but because P can make the silicon steel with cold brittleness, its content should ≯ 0.15% (such as in cold rolled electrical silicon steel, the P content is 0.07 ~ 0.10%). Phosphorus is the most powerful element of ferrite.
pellet mill. A pellet mill is not designed to pellet these materials, let alone the animal stomach to digest them. The pelleting process starts with a bin (Figure 1, Item 1) in which the mixture of mash is stored. From there, the mash will flow by gravity into the pellet mill (Figure 1, Item 2). This machine is
temperature. Cold rolling increases the yield strength and hardness of a metal by introducing defects into the metal''s crystal structure. Hot Rolled Steel is heated up red-hot and pushed through rollers that squeeze the metal, literally squishing it into a par-ticular profile, depending on the shape of the rollers.
C1020 is an AISI designation. AISI typically specifies the chemistry, but not the mechanical properties. Differences in rolling temperature, degree the cross section is reduced, etc. will alter the mechanical properties. Most codes do not permit the use of AISI materials unless they are intended for minor attachments, brackets, etc.

ArcelorMittal Dofasco produces Cold Rolled sheet in a variety of sizes, grades and surface finishes to meet specific end-use requirements. Cold Rolled Sheet is manufactured from hot rolled coils by pickling to remove the surface oxide produced during the hot rolling stage, and cold reducing through a Cold Mill to the desired thickness.

and processed through a set of sizing/shaping rolls which cold-form it into a round (9), square (10) or rectangular (11) section. Form-Square Weld-Square (ERW) Process In the weld mill, driven forming dies progressively shape the ﬂat strip (1) by forming the top two corners (2) of the square or rectangular tube in the initial forming station.
Process. This begins with quality slabs, produced by continuous casting, creating a uniform chemistry for hot rolled steel. The hot strip mill is designed to produce consistent surface quality, uniform mechanical properties, and consistent thickness and crown. Walking .
of cold-rolled steel sheet, generally requires appropriate welding con-ditions in the region of high heat input. This is because zinc is a soft metal that easily conforms to the partner metal and because zinc''s low melting point causes it to melt and spread out during the initial welding stage, thereby resulting in lower current density.
Unannealed hot rolled microstructure Hot rolled products can be come off the mill fully recrystallized, partially recrystallized or unrecrystallized, depending on the alloy, the reduction schedules and the rolling temperature. When recrystallization occurs the elongated, strained hot rolled grains are replaced by a new set of low aspect ratio,

The Braner CTL provides customers with material that is flatter and therefore provides greater productivity. The high-speed line from Braner USA features a 17-roll flattener with a backer assembly and is capable of processing 72″ cold rolled coils up to 30,000 lb x 30″ wide in gauges up from .025 to .220.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
