Abstract
The utility model relates to production equipment for continuous casting and straight rolling of rod and wire. The equipment is characterized by comprising a converter (1), an FL furnace (2), casting machines (3), a straight-through roller way (4), a high pressure water dephosphorizing device (6) and a rolling mill (8). An outlet of the converter (1) is connected with an inlet of the FL furnace (2); an outlet of the FL furnace (2) is connected with an inlet of the casting machine (3); an outlet of the casting machine (3) is connected with an inlet of the high pressure water dephosphorizing device (6) via the straight-through roller way (4); the periphery of the straight- through roller way (4) is covered with heat preserving covers (5); and between an outlet of the high pressure water dephosphorizing device (6) and an inlet of the rolling mill (8), there is provided with a induction heating device (7). By the employment of forming technique without heating, production cost can be reduced and labor expanse can be saved; an intermediate warehouse is unwanted; operation and maintenance cost can be reduced; and exhaust emission is decreased, thereby favoring environmental protection.
Description
Technical field
The utility model relates to a kind of production equipment of excellent wire rod, particularly a kind of adopt continuous casting directly the mode of rolling realize the production equipment of excellent wire rod.Belong to seamless steel pipe production technical field.
Background technology
After the step that rod wire production generally need be through sending under warm cold, the square billet of electric furnace or converter smelting, double refining, billet continuous casting, strand buttress, square billet heating, rolling control are cold, produce finished product, such process route is long process production technique route, relate to operation more, cannot realize continuous casting and rolling, realize at most hot-loading and hot-conveying.Particularly when producing high-carbon steel and alloy steel rod wire rod, center segregation in finished product is still more serious, in order to solve segregation problem, some steel mill adopts two pyrogene material techniques, and continuous casting blooms, after soaking pit heating, is produced little square billet through blooming mill cogging, again rolling after little square billet heating is become a useful person, its shortcoming is to say post bake, causes larger energy resource consumption and environmental pollution, and production cost also exceeds much than traditional handicraft.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides the excellent wire rod continuous casting that a kind of energy consumption is low, cost is low, environmental pollution is little directly to roll production equipment.
The purpose of this utility model is achieved in that a kind of excellent wire rod continuous casting directly rolls production equipment, it comprises converter, FL stove, casting machine, through type roller-way, dephosphorize by high pressure water device and milling train, the outlet of described converter is connected with the entrance of FL stove, the outlet of described FL stove is connected with the entrance of casting machine, the outlet of described casting machine is connected by through type raceway with the entrance of dephosphorize by high pressure water device, the peripheral covering and heat insulating cover of described through type raceway, is provided with induction heating apparatus between the outlet of described dephosphorize by high pressure water device and the entrance of milling train.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is compared with the heating of traditional heating stove, adopts without heating forming technique and can reduce production costs, and investment reduces approximately: 60%; Heat Energy Intensity Reduction approximately: 90%; Reduce scaling loss approximately: 1 percentage point; Improve lumber recovery approximately: 0.8%; Productivity ratio improves approximately: 5%, and amount to ton steel cost and reduce approximately 100 yuan.In addition, can also save labour cost; Do not need intermediate stores; Reduce operation and maintenance costs; Reduce toxic emission, be beneficial to environmental protection.
