摘要： An elongated slot dryer is disclosed for drying wet solid particulate material. The slot dryer is constructed in the form of a trench with at least one aperture outlet at the bottom of the trench formed by two non-connecting walls. The wet particulate material (coal) enters through the top and exits through the bottom aperture while countercurrently contacting a drying fluid emitted through perforations situated in a drying fluid access means or conduit located substantially throughout the entire length of the slot dryer. The perforations in the fluid access means or conduit are limited to the bottom one half of the fluid access means relative to the aperture outlet to ensure that drying fluid is passed at first in a downward direction and then gently turns upward to countercurrent contact with the wet descending particles. An underlying conveyor will act to continuously remove the relatively dried particulate material passing through the aperture outlet. The elongated slot dryer provides an extremely efficient use of the drying fluid while eliminating problems of pressure drop throughout the slot trench drying vessel.
摘要翻译：公开了一种用于干燥湿固体颗粒材料的细长槽干燥器。槽式干燥器以沟槽的形式构造，在沟槽的底部具有由两个非连接壁形成的至少一个孔出口。湿颗粒材料（煤）通过顶部进入并且通过底部孔口离开，同时使位于干燥流体进入装置或导管中的穿孔的干燥流体逆流接触，干燥流体进入装置或导管基本上位于狭缝干燥器的整个长度上。流体进入装置或管道中的穿孔相对于孔口限制在流体通道装置的底部一半处，以确保干燥流体首先沿向下方向通过，然后轻轻地向上转动以与湿气逆流接触下降粒子。底层输送机将起作用以连续地移除通过孔口的相对干燥的颗粒材料。细长狭缝干燥器提供了干燥流体的非常有效的使用，同时消除了整个槽沟干燥容器中的压降问题。

摘要： A process of rolling rimming or semi-killed steel ingots to slabs, comprising removing an ingot from its mold before solidification of the center of the ingot; charging the ingot to a soaking pit and closing the pit; holding the ingot in the pit for the minimum time required to reach a condition wherein more than 85% of the ingot is solidified, the outer rim attains a temperature up to about 525 Fahrenheit degrees cooler than the ingot center and the remainder reaches a temperature at least as high as the desired rolling temperature; and rolling the ingot into a slab. Improved yield, metallurgical quality and minimum energy consumption are achieved.

摘要： In a soaking furnace for heating metal parts, a burner works at full power during a heating-up period and at reduced power during a soaking period. Combustion gases are fed into the furnace with such velocity that the resulting turbulence causes uniform temperature distribution. When the burner is operated at reduced power, the total amount of fuel and air supplied is reduced but the speed of admission to the furnace is increased to maintain turbulence and uniform temperature distribution. The burner includes two concentric parts connected separately to common fuel air manifolds so that one part may be switched off thereby causing higher rate of flow to the other burner part.
摘要翻译：在用于加热金属部件的均热炉中，燃烧器在加热期间以全功率工作，并且在均热期间以较低的功率工作。燃烧气体以这样的速度进料到炉中，使得产生的湍流引起均匀的温度分布。当燃烧器以较低的功率运行时，燃料和空气供应的总量减少，但进入炉的速度增加，以保持湍流和均匀的温度分布。燃烧器包括两个同心部分，分别连接到共同的燃料空气歧管，使得一个部分可以被切断，从而导致更高的流向另一个燃烧器部分的流量。

THE BURNER DIRECTS THE FLAME TOWARD A PORTIN OF THE PIT COVER AT AN OBLIQUE ANGLE. THE COVER DIVERTS THE FLAME AND HEATED GASES DOWNWARDLY ALONG THE REMOTE END WALL OF THE PIT WITHOUT DISSIPATING THE VELOCITY OF THE GASES. THE REMOTE END WALL MAY ALSO BE PROVIDED WITH A SLOPING PORTION TO DIRECT THE DOWNCOMING GASES ACROSS THE FLOOR OF THE PIT.
