introduction：1、Definition of carbon steel and five elements in steel carbonaceous2The following iron carbon alloy is called steel。The five elements in carbon steel refer to the main components of the chemical composition，namelyC、Si、Mn、S、P（carbon、silicon、manganese、sulfur、phosphorus）。The second is the inevitable mixing of gases in the steelmaking process，containingO、H、N（oxygen、hydrogen、nitrogen）。In addition，In aluminium—Silicon deoxidation sedation process，Must contain in the molten steelAl，whenAls（Acid soluble aluminum）≥0。020when，It also has the effect of refining grain。 2、How is steel made？ The main task of steelmaking is to press

introduction：The size of injection volume is related to the accuracy of measuring stroke。Too small，underinjection；Too big，Make the residual amount of the front of the barrel after each injection too large,Make the melt temperature uneven or overheated decomposition。The longitudinal temperature and radial temperature of the melt measured after premolding have temperature differences，Number of screw revolutions，Premolding back pressure and barrel temperature will have a great influence on melt temperature and temperature difference

introduction：In the mold selection is，The principle of economy must be taken into account，Keep manufacturing costs as low as possible。therefore，Under the premise of satisfying the performance，Choose the lower price first，If you can use carbon steel, you dont need alloy steel，You dont need imported materials if you can use domestic materials。In addition，The production and supply situation of the market should also be considered in the selection of materials，The steel grades selected should be as few and concentrated as possible，Easy to purchase。 (one)The mold meets the requirements of working conditions 1、Abrasion resistance When the blank is plastic denaturated in the mold cavity，It flows and slides along the surface of the cavity，Cause intense friction between the surface of the cavity and the billet，Resulting in the mold due to wear and tear failure。
