Abstract
The invention discloses a novel production technology for a ball flat steel. The ball flat steel manufactured by the technology not only has a good quality, but also has a simple process, increases the production efficiency and reduces the production costs. The technology includes the following steps: step I, processing a vertical end surface of a blank and carrying through rolling with fixed width the blank; step II, turning the blank by 90 degrees along the transverse direction and processing a horizontal end surface of the blank; step III, previously fine rolling the blank, and fine processing the upper side surface and the lower side surface of the blank; step IV, fine finishing the upper side surface, the lower side surface, the left side surface and the right side surface of the blank to make into a half-finished product; step V, the half-finished product is processed into a finished product through the working procedures of cooling, straightening, cutting, cutting head and tail and repair grinding.
Description
Technical field
The present invention relates to a kind of production new technique of flat-bulb steel.
Background technology
Need to dispose complicated pass in traditional flat-bulb steel production technology, blank could be processed into finished product through multi-pass is rolling, production efficiency is low; And blank is useless through easily being rolled after repeatedly rolling, and lumber recovery is low, thereby causes the production cost height.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bulb steel production technique, and not only quality is good to use the flat-bulb steel that this technology makes, and technology is simple, can enhance productivity, and reduces production costs.
The present invention includes following steps: the first step, the upright end face of turned blank, it is rolling that blank is carried out Fixed width; In second step, blank is overturn 90 ° the planar end surface of turned blank along horizontal; The 3rd step, pre-finish rolling base material, the upper side of fine finishining blank and downside; In the 4th step, the upper side of finishing blank, downside, left surface and right flank are made semi-finished product; In the 5th step, semi-finished product are processed into finished product after cooling off and through aligning, cutting, crop end, reconditioning operation.
Compare with existing flat-bulb steel production technology, the production technology among use the present invention only needs four passes, blank can be rolled to require size, and production technology is simple, the production efficiency height, and production cost is low.And this production technology can improve 2% with lumber recovery, and the flat-bulb steel quality of manufacturing is good, and mechanical performance is better than the flat-bulb steel that traditional handicraft is made more.
The specific embodiment
The first step is utilized the upright end face of 850 traditional milling train turned blanks, and is rolling by Fixed width, and blank is rolled into needed width; Second goes on foot, and along laterally overturning 90 °, the irregularly-shaped hole of 850 adjustable milling trains is rolling about the planar end surface of turned blank, the blank entry altitude in the present embodiment with blank, and blank is reciprocal back and forth rolling corresponding passage in above-mentioned irregularly-shaped hole; In the 3rd step, blank enters 650 milling train control holes, and blank is carried out pre-finish rolling system, with the upper side and the downside of turned blank; In the 4th step, blank enters 650 milling train finished product holes, and the upper side of finishing blank, downside, left surface and right flank are made semi-finished product; In the 5th step, semi-finished product are processed into finished product after the cold bed cooling and through aligning, cutting, crop end, reconditioning operation.
Claims (1)
1. bulb steel production technique, semi-finished product are processed into finished product after cooling off and through aligning, cutting, crop end, reconditioning operation, it is characterized in that half-finished procedure of processing is: the first step, and the upright end face of turned blank, it is rolling that blank is carried out Fixed width; In second step, blank is overturn 90 ° the planar end surface of turned blank along horizontal; The 3rd step, pre-finish rolling base material, the upper side of fine finishining blank and downside; In the 4th step, the upper side of finishing blank, downside, left surface and right flank are made semi-finished product.
