Description
Technical field
The utility model relates to a kind of high line steel rolling process, more specifically, relates to a kind of high-speed rod production process equipment.
Background technology
Current high-speed rod production mainly contains following two kinds of technology patterns:
1, heating furnace-roughing unit-middle milling train group-pre-finishing mill group-mm finishing mill unit-Laying head-finishing;
2, heating furnace-roughing unit-middle milling train group-pre-finishing mill group-mm finishing mill unit-reducing sizing mill group-Laying head-finishing;
The main difference of these two kinds of patterns is in the finish rolling zone, and traditional mm finishing mill unit is 10 frames, and product specification is φ 5.5mm ~ φ 16mm, dimensional accuracy ± 0.2mm; Increase the production line of reducing sizing mill group, its mm finishing mill unit is 8 frames, and the reducing sizing mill group comprises reducing mill and sizing mill, product specification is φ 5.0mm ~ φ 25mm, and dimensional accuracy ± 0.1mm can realize controlled rolling and control cooling, same groove rolling, technological abilities such as free sizing.
At present steel reinforced is mainly contained two kinds of methods: alloy strengthening and refined crystalline strengthening.Alloy strengthening is to add alloy (as Si, Mn, V, Ti etc.).Refined crystalline strengthening adopts controlled rolling and control cooling technology exactly, refinement steel crystal grain, reach the purpose that improves intensity and toughness, tradition rolled steel grain size is generally at 7 ~ 8 grades, the about 35um of crystallite dimension, adopt the steel grain size of " controlled rolling and control cooling " explained hereafter can reach 12 ~ 13 grades, crystallite dimension 5 ~ 6um.
Test research factually, belong to 35 steel and the controlled rolling of 45 steel process of (Q235+C) type composition design category, even slow cooling also can obtain tiny ferrite+pearlitic structrure.Wherein, ferrite grain size can refine to 2～4 μ m, and quantity obviously surpasses equilibrium quantity.Can just produce high-level (500MPa and above rank) hot rolled ribbed steel bar by this result.
During high-speed rod is produced at present, use the production line of reducing sizing mill group to have tangible advantage:
1, realizes controlled rolling and control cooling (abbreviation controlled rolling and controlled cooling), its main feature has: (1) reduces billet heating temperature, energy-conservation and can also reduce decarburization, the control crystallite dimension can increase the rigidity that rolled piece passes the water-cooled section, reduce accident rate, improve operating rate of rolling mill, and for the rolling condition of having created of low-temperature precise, to produce higher-quality product; (2) obtain having the wire rod of best deformation characteristic; (3) obtain having the wire rod of uniform tissue and stability; (4) iron scale of wire surface generation is thin, is easy to pickling, to reduce the pickling cost; (5) owing to head, tail and the poker variations in temperature minimum of wire rod, performance is even, has reduced crop, the number of turns of back-end crop; (6) for thread wire, deformed bar under the situation that increases trace alloying element, does not improve its reinforced steel bar strength rank by temperature-controlled rolling and control process for cooling; (7) technology advanced person, the production reliability is big, and very high utilization rate is arranged; (8) various production technology economic indicator advanced persons, energy consumption is low.
