Abstract
The rolling mortar for cone crusher has optimized chemical composition of wear resistant steel comprising C, Mn, Si, Cr, Mo, Ti, S and P, and is produced through smelting, casting and proper precipitation strengthening and heat treatment. It has tensile strength up to 994.5 MPa, and impact toughness up to 260 J/sq cm. During the heat treatment, the casting is first heated to certain temperature inside a heat treatment furnace, maintained for certain time and water quenched for forming solid solution; and then heated to certain temperature, maintained for certain time and air cooled for dispersion strengthening. It has raised mechanical performance and wear resistance.
Description
Affiliated technical field:
The present invention relates to a kind of novel wear resisting steel chemical ingredients, melting technology and thermal treatment process, especially gyratory breaker mortar rolled chemical composition, melting technology and thermal treatment process of waiting.
Background technology:
Large-scale cone crusher is widely used in industries such as metallurgy, mine, electric power, coal.The material of its broken wall mainly adopts standard high mangaenese steel such as ZGMn13 series and ZGMn13Cr2 at present.But because foundry goods is thick big, the shrend ability of standard high mangaenese steel is not high, and the mechanical property of crusher is low after the shrend, and continuous work-ing life is short, causes crusher production efficiency low, and it is frequent that spare part is changed in the dressing-works.By research and tracking producer service condition to high-abrasive material, satisfy the needs of wear-resistant maximization, under heavily stressed, thump working condition, possess excellent abrasion resistance, high tenacity, high water malleableize ability, develop novel ultra-high manganese steel material, make producer obtain good operation effect and economic benefit in the use.Compare with standard high mangaenese steel, the mechanical property of novel cone crusher rolled mortar wall material is largely increased, and tensile strength reaches 994.5MPa, and impelling strength reaches 260J/cm
