锻件在锻造厂生产中
锻件在锻造厂生产中,将合理大小的钢锭装炉前,应校对其冶炼炉号、钢号、钢坯重量、尺寸,并检查其表面质量,清除表面缺陷。记录装炉位置,做好锻件生产的实际操作记录。
Forging in forging factory production, the reasonable size of ingot
furnace before, should check that the smelting furnace, steel billet,
weight, size, and check the quality of its surface to remove surface
defects. Record the position of the furnace and make a good record of
the actual operation of the forgings.
锻件所用的钢锭装入炉内的位置应根据炉型、炉底尺寸、装炉方式及被加热钢锭的尺寸重量等确定其距炉子的火墙、前后墙、烧嘴等的距离。严禁火焰直射被加热锻件金属的表面。锻件在锻造前加热时应使用垫铁。垫铁高度应不低于炉子下排烧嘴的高度。直径或边长小于150mm的锻件钢坯加热时可不使用垫铁。
Into the ingot furnace for forging in the position should be based on

furnace and heating ingot size determine the weight from the furnace
wall, back wall and burner distance. It is strictly forbidden to direct
the flame to be heated to the surface of the metal of the forged piece.
The forgings should be heated before the forging is heated. Horn height
should not be lower than the height of the burner stove. The forging
steel billet with diameter or length less than 150mm can not be used for
heating.
锻件采用的钢锭入炉前的表面温度低于400℃的称为冷钢锭,400-550℃的称为半热钢锭,高于500℃的称为热钢锭。冷热钢锭(坯)同装一炉时,其料间间距必须大于一个毛坯的直径或边长。应尽量避免冷热钢锭混装一炉。
The surface temperature of the ingot used in the forgings is known as
the cold ingot at the surface temperature below 400 degrees C, and the
semi hot steel ingot at 400-550 C, which is called hot steel ingot above
500. When the cold and hot ingot (Billet) is installed in one furnace,
the distance between the material must be greater than the diameter or
the length of a blank. Should avoid hot and cold mixed ingot furnace.
