Furnace uses water-cooled wall with full welded film. The width of the furnace is 19558mm and the depth is 16940mm. The elevation of the furnace tube is 74100mm and the elevation of the center line of the drum is 75100mm. The furnace roof adopts a fully sealed structure and is provided with a large cover. ,上部炉膛采用引进型控制循环锅炉的传统布置方式，即布置了过热器分隔屏和后屏，墙式再热器布置在前墙和两侧墙前部。 The grate plate and the upper hearth adopt the traditional layout of the imported control cycle boiler, that is, the superheater partition screen and the rear screen are arranged, and the wall reheater is arranged in front of the front wall and the sides of the wall. 在折焰角上部和水平烟道按烟气流程依次布置了屏式再热器、末级再热器和末级过热器。 In the boiler grate, a screen reheater, a final stage reheater and a final stage superheater are arranged in the order of the flue gas flow in the upper part of the folding angle and the horizontal flue. A low temperature superheater and an economizer are arranged in the rear flue.
随着国家节能环保的快速发展，锅炉炉排成为市场上的热销设备，锅炉炉排是每小时为工业生产提供2吨热水或者蒸汽的锅炉形式，企业在购买锅炉的时候最关心的问题莫过于锅炉炉排的价格了。 Shandong Boiler Fittings Factory , with the rapid development of national energy conservation and environmental protection, boiler grate has become a hot selling equipment on the market. Boiler grate is a boiler that provides 2 tons of hot water or steam for industrial production per hour. At that time, the most concerned issue was the price of the boiler grate. 导致锅炉炉排片价格也不尽相同， 链条炉排锅炉，是一种卧式三回程水火管混合式锅炉，在锅筒内布置一束螺纹烟管。 Due to the different quality and after-sale of each boiler, the boiler grate chip manufacturing factory leads to different prices for the boiler grate chip . The chain grate boiler is a horizontal three-pass water-fire-fire tube mixed boiler in the drum. Arrange a bunch of threaded tobacco pipes. There are light pipe water-cooled walls on the left and right sides of the hearth. The light chain grate is used for mechanical coal addition, equipped with blowers and induced draft fans for mechanical ventilation, and equipped with a scraper slag ejector to achieve automatic slag ejection.
轧制无缝管的原料是圆管坯，圆管胚要经过切割机的切割加工生长度约为1米的坯料，并经传送带送到熔炉内加热。 The raw material of the cross scraper and the rolled seamless pipe is a round pipe blank. The round pipe blank is cut by a cutting machine to produce a billet with a length of about 1 meter, and is sent to the furnace for heating by a conveyor belt. 钢坯被送入熔炉内加热，温度大约为1200摄氏度。 The boiler hood and the billet are sent to the furnace for heating, and the temperature is about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. 炉排 ,圆管坯出炉后要经过压力穿孔机进行穿空。 Beam gun grate of cross beam , after the round tube billet is out of the furnace, it will be pierced through a pressure perforator. Generally, the more common punching machine is a tapered roller punching machine. This punching machine has high production efficiency, good product quality, large perforation diameter expansion, and can wear a variety of steel types. After the perforation, the round tube blank is successively rolled by three rolls, continuously rolled or extruded.
