Embodiment 1

[0041] Embodiment one: as figure 1 As shown, the present invention provides a continuous casting-direct rolling device and method for producing rods, wires and profiles, including a continuous casting machine 1, a slab cutting device and a roller table 2 after cutting, a rapid heat preservation roller table 3, Billet off-line device 4 and steel rolling production line 5, the continuous casting machine 1 is a 5-machine 5-strand continuous casting machine, each stream is independently controlled, the casting speed is 1.5-3.5m / min, and the cross-sectional size of the continuous casting billet is 150mm×150mm The slab cutting device and the post-cutting roller table 2 adopt flame cutting device or hydraulic shearing device, with a fixed length of 12m, the post-cutting roller table is driven by a frequency conversion motor, the surface speed of the roller is 0.025-2m / s, and a heat preservation device is installed; The fast thermal insulation roller table 3 is a climbing roller table...

Embodiment 2

[0042] Embodiment 2: as figure 2 As shown, the present invention provides a continuous casting-direct rolling device and method for producing rods, wires and profiles, including a continuous casting machine 1, a slab cutting device and a roller table 2 after cutting, a rapid heat preservation roller table 3, Billet off-line device 4 and steel rolling production line 5. The difference from Example 1 is that the billet off-line device 4 is set at the slab cutting device and the cut roller table 2, before the fast heat preservation roller table 3, when the rolling line changes rolls and slots, accidents occur, and production is stopped for maintenance, Or when the hourly output of continuous casting is greater than the hourly output of steel rolling, the redundant billets are cooled off in rows through the billet off-line device 4 .

Embodiment 3

[0043] Embodiment 3: as image 3 As shown, the present invention provides a continuous casting-direct rolling device and method for producing rods, wires and profiles, including a continuous casting machine 1, a slab cutting device and a roller table 2 after cutting, a rapid heat preservation roller table 3, Billet off-line device 4 and steel rolling production line 5. The difference from Example 1 is that the device uses a multi-machine multi-stream continuous casting machine 1 corresponding to two steel rolling production lines 5 to match the output balance between continuous casting and steel rolling. The two steel rolling production lines can be used to produce rods and wires of the same product , profile production line, or bar, wire, and profile production line for the production of different products. The continuous casting machine adopts a ladder-shaped billet discharge method. After the billets are cut successively, according to the output matching situation, a singl...

Abstract

The invention relates to a continuous casting-direct rolling device for producing a rod wire and a section bar. The device comprises a continuous casting machine, a casting blank cutting device, a after-cutting roller way, a quick heat-insulating roller way and a steel rolling production line, wherein the continuous casting machine is arranged as a one-machine one-flow or multi-machine multi-flow continuous casting machine; the roller way width of the quick heat-insulating roller way is gradually reduced along the direction from the continuous casting machine to the steel rolling production line till a single casting blank can pass; a plurality of hot metal detectors, a pyrometer and a heat-insulating device are arranged on the quick heat-insulating roller way; the device further comprises a casting blank unloading device; the casting blank unloading device can be selectively arranged in front of the quick heat-insulating roller way or the steel rolling production line. The invention further provides a continuous casting-direct rolling method for producing the rod wire and the section bar. According to the invention, a traditional heating furnace is cancelled and the metallurgy thermal energy of a continuous casting blank is fully utilized, so that the energy consumption and the discharging in the production of the rod wire and the section bar are greatly reduced; the technological process is simplified, the equipment investment of a heating furnace area is reduced, and the cost is lowered; the oxidation burning loss of the billet is reduced and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of continuous casting and rolling of rods, wires and profiles, in particular to a continuous casting-direct rolling device and method for producing rods, wires and profiles. Background technique [0002] At present, there are generally two production processes for rods, wires and profiles, one is continuous casting → billet off-line cooling → cold billet feeding → heating furnace heating → rolling, and the other is continuous casting → hot delivery and hot charging → heating Furnace heating → rolling. Due to the long cooling time and low temperature after the continuous casting slab is cut, these two production processes cannot meet the rolling temperature requirements of the rolling mill. The continuous casting slab must be reheated by a heating furnace before rolling. There are four main problems in heating with a heating furnace: first, the energy consumption is huge, and the fuel consumption of the heat...
