Recyclable Low-rise Residential Building Light Steel Villa with Dry Construction Method Light steel construction technology is a production system where building elements are produced from galvanized steel with cold forming process. The building details whose structural design is realized are conveyed to the machine and formed on the specially designed Structure Robot lines. Human errors are minimized by means of prefabrications realized in factory environment and on robot lines.   Prefabricated house is more stable than the one that made of welding frame steel . Besides, it is cheaper, more economic. With long lifespan, which can last almost 70 years, all the materials of Prefabricated house is Q550. It is locked with bolts, which can be used repeatedly without any maintenance.   Prefabricated Houses are structures ready for construction and first degree earthquake resistant. Prefabricated houses are flexible and light buildings. They only shake and do not get torn down even in strong earthquakes. Mounting period of prefabricated houses are much shorter than concrete buildings. Besides these dwellings can be demounted and mounted time and again. The ready for construction houses we mentioned can be produced with heating and static calculations proper to all kinds of climate conditions. The houses do not corrode, deform and can be used securely for many years, because the whole load-bearing system is made from high density galvanized steel.   Specifications: Item name Recycled Low-rise Residential Building Light Steel Villa with Dry Construction Method Design standard US /NZ/AS/CE/ China GB, as per the custom request Building types Small steel framed buildings like steel garage sheds,agricultural buildings includes steel poultry sheds, simple storage house,etc. Large buildings includes high-rise&multi-storey office building,steel factory warehouse plant,large steel structure stadium buildings,etc Main frame Normal steel frames/Truss / Grid structure,etc based on actual project demands Materials Q235,Q345B,or other replaced materials equivalent to other standard Roof EPS /PU sandwich panel, rock wool, glass wool,lightweight foaming cement panel, single color sheets, or custom materials,etc Ceiling Gypsum or sandwich panel Exterior walls Optional Partitions Optional Doors Optional Windows PVC sliding window, aluminum alloy insulating windows with single/double glass ,etc Ground Beam C steel Post Double C steel Ring Beam C steel Floor Purlin C steel Roof truss C steel Roof Purlin L40 angle steel Stair Steel stair,or hot-dip galvanized ,etc Corridor Step Board checkered steel board,optional Floor Board plywood board, cement bricks, wooden tile, optional Water Pipes &Electrical We can design &produce it Based on standards in local place, or just reserve the hole in advance ,etc Color Blue/Red/White/Others colors as per customer's request     Performance & characteristics: 1.Environmentally friendly, no waste produced during assemble. 2.Flexibility when fixing doors, windows and interior partitions. 3.Beautiful appearance, different colors for the walls and roof. 4.Cost saving and convenient to transport. 5.Rust proof at least around 15 years service life. 6.Good ability to assemble and disassemble for several times. 7.Heatproof, sound proof and waterproof,etc   Advantages: 1.Galvanized steel or painted steel as the major part of structure which is firm and durable, it has quite good capacity to resist corruption. 2.Fast construction and easy installation. 3.The main material of the wall, roof is light and strong.

High Speed Steel Mill Rolls for Hot Rolled Metal Sheet And Billet Mill Usage High speed steel mill rolls, produced by horizontal Centrifugal casting process, are all compound rolls with high speed steel as the work layer and nodular iron as the core. The material of rolls contains plenty of alloyed elements such as Mo, V, W, Cr etc. The high hardened eutectic carbides & second carbides, such as MC, M2C, M6C evenly distributed in tempered martensitic matrix, make the wear and thermal cracking resistance very excellent. Besides, the resistance to surface roughing is also good. In condition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. FAMOUS rolls are mainly used as the work rolls in the hot strip mills and the finishing stands of bar mills; rings of the universal section mills and finishing stands of the high speed bar mills.   Usually, we make this type of roll by static cast and centrifugal cast. We recommend using centrifugal cast rolls for better performance when the groove in the roll body is not too deep. With more alloy added in, we can get a microstructure consisting of spheroidal graphite, pearlite and primary carbide type M3C up to 30%. Meanwhile, the core of the roll still keeps very strong with a great amount of spheroidal graphite in the matrix of ferrite. When the groove in the roll body is very deep, we recommend using rolls static cast with groove to achieve a low hardness drop between the body surface and bottom of the groove.   Specification:   Production Name: Forged Work Rollers  Certification: CE,BV,TUV,SGS,ISO9000 Technology: forging,open die forging,free forging,ring forging,stamping,hot,rolling Equipment: CNC Machining Centres Material: Carbon steel,Alloy steel,stainless steel Surface treatment: Heat Treatment,oxide coating,plating,finishing,painting,galvanized Model Number: Custom According to Drawings Application: Engineering Construction Machinery Chrome thickness: 25~30micron Length: 1001mm~10000mm Weight: 11kg-3200kg Tolerance: 0.01mm Roughness: Ra 0.20micron (max) Packing: Wood box for free fumigate or according to customers' requirements Shipment  Sea shipment or customized requirements,etc   Production process :   Characters:   1.

The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for re-rolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.   Application:   The spheroidal graphite pearlitic iron rolls are widely used in the roughing stands and intermediate stands of various rolling mills.
