| Message: | Oil quenching - tempering steel wire ProductsAbstract: This paper briefly introduces the characteristics of oil quenching-tempering steel wire, the current product standard, product development direction; and the production process and process control points, which provides useful information for the users to choose the steel wire grade and order quality products.Key words: oil quenching - tempering treatment, pre-hardening treatment, multiple tempering, on-line flaw detection.Special part of the steel products in the final need to quenching - tempering state, the traditional approach is to provide cold-drawn metal products factory annealing or state of the wire, the downstream enterprises will be made of steel wire parts or components, and then quenching + back Fire treatment, toughness to meet the scheduled requirements after delivery. Because the size of parts or components, shape ever-changing, bring the final heat treatment furnace vary widely, will inevitably lead to increased production costs, heat treatment performance fluctuations. Now gradually evolved into: the shape is not complex, easy processing of parts or components with wire quenching and tempering treatment transferred to the fabricated metal products factory, which formed a new species - quenching - tempering steel wire.1. OverviewOil quenching - tempering: a wire that is drawn to the finished size and quenched and tempered in a continuous furnace. The unwound wire is first heated to full austenitizing temperature in a continuous furnace and then quenched by oil bath Martensite, and then through the continuous furnace tempering, to obtain the expected strength and toughness. Oil quenching - tempering steel wire straightness is good, the uniformity of mechanical properties, made of components or components only after low temperature stress treatment that can be used directly.Oil quenching and tempering heat treatment furnace is composed of tension releasing device, heating furnace, oil quenching tank, tempe......url:http://www.cnfuruide.com |
