发明| 感应电炉磁轭
感应电炉磁轭是感应电炉中的重要部件。感应线圈通电时,磁轭产生大量的热量,必须及时、快速地进行散热。
传统感应电炉磁轭包括硅钢片组两侧的不锈钢板、冷却水路、进水口和出水口。该结构的生产方式为使用专用工装,将两侧不锈钢板、背板、矽钢片放置到专用工装上后,使用油缸压紧后焊接,然后,在不锈钢侧板焊接冷却水路。由于工序多,耗时长,焊缝长,耗时且冷却水易泄露。并且,冷却水路的冷却面积较小,造成冷却效果较差。
新研磁轭技术提供一種感應電爐磁轭,以克服上述現有技術的存在缺陷。包括:層疊的矽鋼片組、背板、兩個側板和若幹個固定板;其中,側板爲中空板,對稱地固定在背板的兩側;矽鋼片組,設置在側板之間;固定板,具有固定安裝孔,固定板的兩端分別與兩個側板固定連接。設置在矽鋼片組兩側的側板爲中空結構,不必要冷外在焊接冷卻水路,就具有冷卻水的流體通道將冷卻功能和支撐功能整合爲一體,增加磁轭背面上下水路,減少軟管接頭,從而減少了漏水點。
另外,新研磁轭技术提供一种感应电炉磁轭还增加了与侧板连通的中空连通管,连通管和侧板形成循环;实现过水面积、通水截面最大化,低進出水口的壓差,從而強化冷卻效果,並使磁轭散熱更加均衡。同時,優化了産品工藝,可以采用了框架式,模塊化裝配生産,在不影響質量穩定的前提下,降低了對裝配的要求。由于焊縫長度大幅縮短,降低了工時,從而效率大幅提高。(專利號:2014100299155)
"Excuse me," Arthur ventured, huskily, "did you wish to speak to me?" "What!" Balmayne cried, "were you mad enough to----." seventeen Christmas presents? I'm a Socialist, please remember; And to close the procession came more soldiers. For that fog the seaplane was making at full speed. It was no wonder that Spain, feeling the serious effects of this state of things, should resist it; and when she did so, and exerted an unusual degree of vigilance, then the most terrible outcries were raised, and wonderful stories were circulated of Spanish cruelties to our people beyond the Atlantic. At this time the Opposition got hold of one of these, and made the House of Commons and the nation resound with it. It was, that one Captain Robert Jenkins, who had been master of a sloop trading from Jamaica, had been boarded and searched by a Coastguard, and treated in a most barbarous manner, though they could detect no proof of smuggling in his vessel. He said that the Spanish captain had cut off one of his ears, bidding him carry it to his king, and tell his Majesty that if he were present he would treat him in the same manner. This story was now seven years old, but it was not the less warmly received on that account. It excited the utmost horror, and Jenkins was ordered to appear at the bar of the House of Commons on the 16th of March, to give an account of the outrage himself; and it would appear that both he and other witnesses were examined the same day. Jenkins carried his ear about with him wrapped in cotton, to show to those to whom he related the fact, and the indignation was intense. He was asked by a member how he felt when he found himself in the hands of such barbarians, and he replied, "I recommended my soul to God, and my cause to my country." The worthy skipper had probably been crammed with this dramatic sentiment by some of his clever Parliamentary introducers; but its effect was all the same as if it had been a genuine and involuntary expression of his own mind. Researches made at the Admiralty in 1889 proved that he really had lost an ear. Nevertheless, the whole army was dead beat and in the most deplorable condition when they entered Carlisle on the morning of the 19th. As the enemy did not appear, they rested that day and the following night, when they set forward again, leaving a fresh garrison. Cumberland was soon up before the walls, and they fired vigorously at him; but he sent off to Whitehaven and brought up six eighteen-pounders, with which, to their dismay, he began to play on their crumbling walls on the 29th. Next morning they hung out a white flag, and offered to capitulate; but Cumberland would hear of no terms except their surrendering on condition that they should not be put to the sword. At three o'clock in the afternoon both town and castle were surrendered, the garrison being shut up in the cathedral, and a guard set upon them. On the 3rd of January the Duke of Cumberland left the command to General Hawley, and hastened back to London, being summoned to defend the southern coast from a menaced landing of the French. In pursuance of this plan of the campaign, Prideaux and Johnson arrived before the fort of Niagara in the middle of July, which they found very strong, and garrisoned by six hundred men. Prideaux was soon killed by the bursting of a shell, but Johnson continued the siege with great ability, having to invest the fort on one hand, whilst he was menaced on the other by a mixed body of French and Indians, one thousand seven hundred in number, who came to relieve the fort. The attack upon him commenced with a terrible war-whoop of the Indians, which, mingling with the roar of the great cataract near, made the most horrible din imaginable. But this did not disconcert the English and their savage allies, who received them with such steady courage, that in less than an hour they were put to the rout in sight of their own garrison, and pursued for five miles with dreadful slaughter. The garrison thereupon capitulated, remaining prisoners of war. There, however, Sir William Johnson's career stopped. From various causes, not foreseen, he was not able to advance beyond the Ontario to unite with Amherst. That general had fully succeeded in taking Ticonderoga and Crown Point, but he found the French so strongly posted on an island at the upper end of Lake Champlain, that he was compelled to stop and build[134] boats to enable his army to reach and dislodge them; and it was not till October that he was ready to proceed, when he was driven back repeatedly by tempests, and compelled to go into winter quarters. "Some of you find Lieut. Bowersox, and bring him here," said Capt. McGillicuddy, sitting up, and beginning to twist a handkerchief around his thigh, to form a tourniquet. "Lieutenant, you all right?" The old man mounted into the seat, gathered up the rope lines, and chirruped to the horse to start. He hitched forward cautiously a little farther, to where he could peer through the bushes, being exceedingly wary not to repeat his opponent's mistake, and set their tops in motion. A rock protruding through the ground in front of him made an opening through which he could see, and also afforded a rest for his musket. He looked sharply, and at length was rewarded by seeing the gun-barrel come out by the side of the barked willow, rested on a bare limb, and apparently aimed at the hill beyond. He took a long breath to steady his nerves, stretched out his legs to make himself more at ease, pushed his musket forward until he got exactly the right poise, aimed about nine inches below the level of his opponent's gun-barrel, and a little to the left, drew his bead down to a hair's nicety in the hind sight, and pulled the trigger just as the rebel sharpshooter did the same. Both muskets seemed to flash at the same moment. The rebel sprang up through the willows and fell forward on his face. There was a vague hint that he had seen the face somewhere, but he dismissed it, then settled himself, and, busy with his own thoughts, pressed his face against the window, and tried to recognize through the darkness the objects by which they were rushing. They were all deeply interesting to him, for they were part of Maria's home and surroundings. After awhile the man appeared temporarily tired of billing and cooing, and thought conversation with some one else would give variety to the trip. He opened their lunch-basket, took out something for himself and his companion to eat, nudged Shorty, and offered him a generous handful. Shorty promptly accepted, for he had the perennial hunger of convalescence, and his supper had been interrupted. It was their regiment—the 200th Ind.; it was made up of the same companies, with the great majority of the men the same, but it was very far from being the 200th Ind. which crossed the Ohio River in September, 1862. "I should say he had a mighty strong breath, Monty," Shorty interrupted. He liked to break in on Monty's heroics. "Excuse me from havin' a 12pounder breathin' around me." "Yes, but d?an't m?ake him angry—he might beat you." "I used to be in the fancy," said the minister, "but five years ago the Lord challenged me, and knocked me out in the first round." "We shall talk further," said Holgrave: "in the mean time, we must consult for your own safety. If your father was a villein of this barony, it is not likely that the old steward, or the new one—the fiend Calverley—should forget you; and——"
