Title Steel Coil Production Process
Description The production process of a cold-rolled steel coil is generally as follows: pickling, rolling, process lubrication, annealing, leveling, shearing, packaging. High quality cold rolled steel coil china process: pickling -- rolling -- annealing -- rolling size synchronous lubrication -- anti-rust oil -- flat size -- polishing -- packaging. Heating furnace of hot rolled steel coil craft: - phosphorus removal machine, roughing mill, phosphorus removal machine, finishing mill, surface quality inspection instrument - a layer of the cold - reel, baling machine, injection machine - volume base slab. Hot-rolled coil production process: first of all within the furnace temperature up to the required rolling temperature, and is entered into the roughing roller on the slab of phosphorus removal machine of iron oxide, and then into the roughing rolling unit for the width and thickness of the steel roll for rolling, again by the roller conveyor to finishing phosphorus removal machine for steel coil surface tin oxide produced by processing, after entering the finishing rolling unit thickness and width of steel roll more precision rolling, steel coil by roller through a layer of cold surface temperature before coiling, after strict control into the reel be coil last baling, spray into the packaging volume of inventory.
