Manufacture and use of the car plate, will involve a number of related terms. The following table lists the more common terms: aging - changes in the physical and mechanical properties of low carbon steel after a storage period of time after the generated. Temperatures can accelerate the aging process. Annealing - rolling cold rolling the substrate after high temperature heating and cooling, in order to reduce the hardness, and soften or become more forming process. Camber - strip-side edge deviation from a straight line, the measurement has been taken the concave side. Carbon steel - mainly refers to the mechanical properties depend on the carbon content of the steel, and generally do not add a lot of steel alloying elements, sometimes referred to as carbon steel or carbon steel. Chemical treatment - the coating surface coating products, such as chromate or phosphate waterproof anti-corrosion chemical processes. Tensile strain marks - surface defects after press forming, a series of parallel lines with the rolling direction at 45 ° folds appearing on the plate or irregular polyline, orange peel, etc., will generally extend to the steel sheet or strip full width. It is caused due to aging steel. Cold rolled product - rolling at room temperature and to achieve the desired final thickness required size commercial grade steel flat rolled products (CS) - mass of the kind of sheet can be used for simple or slightly bent shape. At room temperature, it can bend in any direction and bonded to itself. Casting - Continuous pulled through the bottom of the mold and solidified to form a continuous strand process. Corrosion - chemical or electrochemical at atmospheric moisture or other media erosion, metal gradual erosion phenomenon. The key surface - or paint used to expose the surface defects on the surface should be avoided painting. Crown - from plate edge to the center position, increasing the thickness of the contour line. Cutting edge - the edge shape is obtained after a user-specified width of the cut edge of the strip is formed. Cut Length - equal or unequal length requirements. Deep Drawing - Use the punch die, the processing of metal blank into a cup shaped like a process. Stamping - forced by plastic flow of metal, in the blank forming die to process concave part. Punching Steel (DS) - compared with the commodity steel, this steel has a higher quality level of ductility and performance uniformity. Manufacture and use of the car plate, will involve a number of related terms. The following table lists the more common term: deep drawing steel (DDS) - time when demanding stamping steel ductility can not meet the time of the manufacture of parts, or require the steel sheet not appear aging phenomenon, deep-drawing steel should be used . Its performance is achieved by a special manufacturing process of smelting and obtained. Bake-hardening steels - This steel has both strength but also has a high formability. To obtain the strength of the final part of the process by work hardening during the paint and aging phenomena. Ultra-deep drawing steel - this steel has excellent formability and excellent performance uniformity, is a very low carbon content, and joined the stable alloy seamless steel elements. It is a phenomenon does not occur aging steel. DS Type B steel - used for stamping and forming more stringent requirements. Ductility - before fracture permissible deformation. For flat rolled products, usually in hardness or tensile test to measure the mechanical properties of ductility. Elongation - fracture in a tensile test before elongation percentage specified length section. Flatness - Flatness is consistent with the horizontal plate degree measure. Usually measured roughness index, which is the maximum deviation from the horizontal plane of the surface and the distance of the steel sheet. Flatness steepness or I may also be expressed in units. Hardness - metal surface into compression capacity. High-strength low-alloy (HSLA) - by adding a small amount of alloying elements to achieve the desired level of intensity of a particular type of steel. The most common alloying element known as niobium, vanadium, titanium and the like. Hot rolled steel sheet - a high temperature on the hot-rolled rolling device and processed into a final thickness of the plate. Hot-rolled pickled products - hot rolled pickled products, oiled, smooth and cropping and processes to meet the requirements of the size and dimensions. Inclusions - after casting, the presence of foreign substances in the steel (such as oxides, sulfides, or silicates). Inclusion shape control - the use of rare earth metal or calcium alloy inclusions form control provides improved mechanical properties for specific applications. Killed steel - steel before the solidification of silicon or aluminum deoxidation, the oxygen content of the molten steel to a minimum. Compared with other types of steel, killed steel properties and chemical composition of more uniform. Straightening - by reducing or eliminating deformation of the sheet after rolling become straight. Mechanical properties - apply force to the material exhibits flexibility and performance of non-elastic properties of the material used to indicate the suitability of the material for mechanical applications. Oiled - or temper rolling after pickling oiled steel coil reduces abrasion between the circle and circle, improve lubrication and anti-rust performance has a certain degree, to provide customers with certain products for processing Help. Manufacture and use of the car plate, will involve a number of related terms. The following table lists the more common terms: oiled board - the final product after processing step plate coated with the oil. The purpose is usually oiled during transport and storage in order to prevent rusting. These oils are called anti-rust oil. Oil coating can also assist the subsequent processing, but this is usually not the main purpose. For improving the formability of the oil is commonly referred to as "pre-lubricant." Pickling - by a chemical reaction to remove the metal oxide surface. Pre Lubricant - an oily coating for improved formability (deep drawability) and applied on the steel plate. When users want to avoid using this lubricant in his unit in the coating forming lubricant. Quality - the term used to describe the degree of perfection plate. Usually refers to the surface quality of the steel sheet, without scratches and cracks. Quality may also refer to other properties, such as no internal defects, and control precision dimensions and the like. Roll forming - after a series of continuous metal sheet rolls, to achieve a continuous deformation, to obtain a predetermined processing shape. Slitting - in the width direction of the steel cut into two or more processes. Spangle - usually refers to the hot galvanized plate is pulled out from the zinc pot, along with the appearance of the zinc layer is cooled and solidified after the formation of grains performance. Spangle size, brightness, and surface morphology depends on a number of factors, but mainly with the zinc layer composition and cooling methods. Structural steel - steel refers to meet specific strength and formability levels. Can be formed after the tensile elongation at break, said the test. Structural steel usually used for carrying purposes, the strength of steel in these applications is an important design criteria. T- Bend - Lumber sample can be determined according to the sheet thickness of the inner bend radius, bonded to their mechanical operation. For example, 2T represents the apex radius equal to two times the plate thickness test. Stretch straightening - the coil straightening device by stretching stretch beyond product yield point, causing permanent deformation approach. Stretch straightening can obtain good flatness. Temper rolling - slight thinning of cold steel plate depressed. The purpose is to improve the formation flatness, eliminate discontinuous plastic deformation and obtain uniform surface. Tensile strength - Tensile test material can withstand maximum stress. It is the ratio of the maximum load of the original cross-sectional area. Tolerance - allows a deviation amount of terminology size. For example, the sheet thickness, width, flatness and camber tolerance there. Yield point - do not continue to increase even if the load applied, the deformation of steel continue to occur corresponding to the load or stress value is known as the yield point. Yield point is one characteristic of the low-carbon steel after annealing. Yield strength - refers to materials from the linear portion of the load and elongation curve deviation reaches a predetermined value corresponding to the stress. In the tensile test, the yield strength of the material generally refers to 0.2% offset strain curve corresponding to the load from the linear segments.
