前言: φ760×1200毫米两辊周期式热轧薄板车间是在五十年代建成的,每台轧机配借一座链式加热炉,这种炉型结构存在下述缺点。 1.原设计采用高压喷射式烧咀,需要1300毫米水柱以上的煤气压力,消耗的电能较高。 2.小型号的喷射式烧咀的空气无法预热。 3.链式加热炉的炉链和炉爪带走的热损失很大。经热平衡测试带走的热损失占整
Preface: The φ760 × 1200mm two-roll periodic hot-rolled sheet workshop was built in the 1950s. Each rolling mill is equipped with a chain-type heating furnace. This type of furnace structure has the following disadvantages. 1. The original design using high-pressure jet-burning Tsui, the need for more than 1300 mm gas pressure of water column, consume more energy. 2 small jet nozzle burning air can not be preheated. 3. Chain furnace furnace chain and furnace claw away heat loss is great. The heat loss taken away from the heat balance test takes up the whole
