Abstract
The present invention relates to the hot continuous rolling process for a band steel board bar, which is characterized in that the hot continuous rolling process of the band steel board bar has the process steps of cold rolling, hot rolling, deformed steel and wire products. Firstly, a band steel edge-roiling disk is put on a disk-positioning machine and then is coiled on a bar coiling machine after the band steel edge-roiling disk is rolled through a rolling mill; the band steel bar which is rolled in a cold rolling mode is put on a feeding disk and then is preheated for the slow temperature rise; when the stabilization can reach an austenite temperature, the high temperature heating is carried out in a stove. The band steel bar enters a one-track vertical rolling mill for the flat rolling treatment, enters a two-track horizontal rolling mill for the edge rolling, enters a three-track vertical rolling mill for adjusting the thickness, and then enters a four-track horizontal rolling mill for the rolling; thereby, the physical size of the product design can be achieved. Furthermore, the band steel bar passes through fine pulling treatment on a roller type mould and then is coiled on the coiling machine. The present invention can process the band steel side materials into the deformed steel and a wire qualified product for the secondary process, the technical yield rate can be increased by 8 %, the power consumption can be reduced by 40 %, the labour cost can be reduced by 35 %, and each item index through the detection can achieve the national standard.
Description
Technical field
The present invention relates to a kind of band steel plate bar hot continuous rolling process.
Background technology
At present, enterprises such as domestic metallurgy industry steel tube factory, steel tubes factory, strip mill cut strip edge that roll bending gets off and are mainly used in hot candied factory and carry out wire drawing, its production technology is: cut bar--cold rolling--wire drawing--wire product.Even this product material is qualified, also exist physical property not reach the requirement of national quality examination criteria.Therefore, some enterprises roll into featheredge with thick strip edge, but have the high problem of cost, and quality testing does not pass a test.
Summary of the invention

The first step: at first steel tube factory, steel tubes factory, strip mill etc. are cut the strip edge reel material that roll bending gets off, the strip that waste steel plate, steel scrap pipe shear off, weld by butt welding machine, rolling through rolling mill, adjust the physical size of product, to be with steel bar to be entangled on the bar machine, for next step hot rolling is got ready;
Second step: with the cold rolling band steel bar that shuts out, be placed on the loading plate, at first be with steel bar to enter in the heating furnace preheating zone, band steel bar in the room temperature is slowly heated up, when stable when being about to reach austenitic temperature, in the heating furnace high-temperature district, the band steel bar teases on two fire-resistant bodies mutually across, twine 1～3 circle, help temperature raising speed, temperature rises to 1000～1200 ℃;
The 3rd step: after coming out of the stove, the band steel bar advances vertical rolling mill together, puts down and rolls processing, advances the horizontal rolling mill in two roads then and carries out rolling on edge, and reaching next passage needs size; Enter the vertical rolling mill in the 3rd road again, enter the physical size that the horizontal rolling mill in the 4th road reaches product design after rolling after thickness is adjusted;
The 4th step: after pulling out processing through essence on the roller die again, be entangled on the spooling machine.
Band steel plate bar hot continuous rolling process of the present invention, overcome in the prior art metallurgy industry has been cut the technological deficiency that exists in the strip edge material secondary operations that roll bending gets off, realized strip edge material secondary operations is become deformed steel and wire rod qualified products, its lumber recovery can improve 8%, reduce power consumption 40%, reduce labour cost 35%, adopt this technology to test, examination is rolled the every after testing index of product and has all been reached national standard.
