过去,我们使用的取样勺由铸铁铸成。以后又改用铁皮制成小手端包式样,以耐火砖末加耐火粘土(2:1)再加适量水混制的衬料修砌。但因受高温铁水烘烤,其衬料易剥落,使用寿命较短。为解决这个问题,我们采用废电极棒,在车床上车出凹面,然后用手锯或钢锯在其上锯出一个三角口为流铁水嘴,手柄用φ14mm In the past, the sampling spoon we used was cast from cast iron. Later changed to the small handbag made of metal to the end of the refractory brick at the end of refractory clay (2: 1) plus a moderate amount of water mixed lining repair. However, due to high temperature hot metal baking, the lining easily peel off, short life. To solve this problem, we use the waste electrode stick, car out of the concave on the lathe, and then use a hand saw or hacksaw to saw a triangle on the mouth for the flow of hot metal tap, the handle with φ14mm
