工業鋁型材挤压痕是怎么产生的？

铝合金在经过挤压成型后再进行表面处理就成了完整的工業鋁型材。除了完好的工業鋁型材，其实工業鋁型材 在挤压过后有一些型材还是表面带挤压痕的。这种挤压痕是一种型材表面沿着挤压方向的连续的线条。使得工業鋁型材产生这种线条的主要原因来自模具、挤压工艺和原材料三个方面。

1. 从模具方面来分析，工業鋁型材的挤压模具必须具有合格的光洁度。模具和型材接触的表面一定要光滑平整。不平整模具接触面会导致挤压出来的铝型材表面有很多线条产生。另外，挤压过程中的加温工艺及工作带长短都会影响线条的产生。比如抛光效果不好的模具或者工作带长的时候，通过模具挤压出的产品的表面会产生挤压痕。而且模具的加温时间过长，温度过高也会使得通过模具挤压出来的型材表面有挤压痕。

2. 从工業鋁型材擠壓工藝方面，擠壓溫度越高，擠壓筒裏面鋁合金的粘粘度增加，這些都會是的擠壓出來的鋁合金型材表面帶有擠壓痕。而且擠壓速度也有導致擠壓痕的出現，擠壓速度不能過快，否則擠壓痕會比較多。带挤压痕的工業鋁型材是不合格的，因为我们美诚铝业出厂的工業鋁型材一定是要表面光洁平整的。下篇我们根据我们厂生产经验给大家分析如何避免和减少挤压型材的挤压痕的存在，提高铝型材的挤压合格率。

‘Well, if that isn’t a rude speech! But perhaps you’re tired, Thomas, with all this grandeur. For me, I never felt fresher in my life: it comes quite natural to me.’ ARCHERY ATTENDANT. ARCHERY ATTENDANT. The Japanese are excellent sailors, both on their junks and on the foreign ships that have been introduced to their service since the opening of the country to other nations. But the Japanese landsman has a horror of the water, and cannot be induced to venture upon it. In this respect the Japanese are not unlike the Italians, who are naturally a maritime nation, and have covered themselves with marine glory in times that are past. But the Italian landsman is ready to suffer any inconvenience rather than risk himself on the ocean, and not a more woe-begone being can be found in the world than a sea-sick Italian unless it be a sea-sick Japanese. HORSE CARRYING LIQUID MANURE. HORSE CARRYING LIQUID MANURE. No, he would not; only wagons went that way, to cross the creek by a small bridge. I could cut off nearly two miles by taking the bridle-path that turned sharply down into the thick woods of the creek-bottom about a quarter of a mile from the house and crossed the stream at a sandy ford. "Ride round," he said, "and I'll show you from the front of the house." Plato or bridge--is fundamentally and always interested in clothes. I've been writing a book, all last winter in the evenings, and all 24 Now for a race, Larry muttered, almost automatically moving the throttle wider as he prepared to alter their course. She did not. He had merely told her that her father was his friend and had died on the plains. "She thinks her mother died at Stanton. It is so near the Mescalero Agency that I let it go at that." papers reports that he was kild at thfe battle of "Do you men know of a squad of Injianny recruits commanded by Serg't Klegg?" "Where may I learn the others?" But Gornom didn't answer, and Cadnan's breathing-space was over. He had to be back at the board, pushing buttons, watching carefully. Gornom stood behind him, peering over his shoulder with a cloudy eye. Neither said a word until the new spell of work was over. Then Cadnan repeated his question. Being excerpts from memo directives sent between executives of Associated Metallic Products, Ltd., a corporation having its main offices within Dome Two, Luna City, Luna, and associated offices on all three inhabited planets, the memo directives being dated between May fourteenth and May twenty-first, in the Year of the Confederation two hundred and ten. During the next ten years the farm went forward by strides. Reuben bought seven more acres of Boarzell in '59, and fourteen in '60. He also bought a horse-rake, and threshed by machinery. He was now a topic in every public-house from Northiam to Rye. His success and the scant trouble he took to conciliate those about him had made him disliked. Unprosperous farmers[Pg 124] spoke windily of "spoiling his liddle game." Ditch and Ginner even suggested to Vennal that they should club together and buy thirty acres or so of the Moor themselves, just to spite him. However, money was too precious to throw away even on such an object, especially as everyone felt sure that Backfield would sooner or later "bust himself" in his dealings with Boarzell. "This place suits me, and I think I could do well for myself out here. I feel I should get on better if I was my own master.... She was good and sensible-like, and looked as if she could manage things. So I married her.... We're starting up on a little farm near Jo'burg ... I can't see it matters her being Dutch ... fifty acres of pasture ... ten head of cattle ... niggers to work ..." The treasurer turned pale, and hung his head.
