淬样圈时,一般先把样圈放在电炉里预热,再在盐炉中加热,要用好几名操作工人。采用附图的工具,可以使生产过程机械化,减少设备和操作工人,并且提高了生产效率。这付工具是利用2～3公厘厚的废铁板焊成的,中间开一个长方形沟槽,再焊一个牛角形漏斗槽子。加热时,把方形盘放在盐炉上(注意不要接触电极),把样圈放在沟槽两边预热。经过一定时间,把样圈放
Quenching the ring, the general first sample circle on the electric furnace preheated, and then heated in salt furnace, to use several operating workers. With the drawings, the tools make it possible to mechanize the production process, reduce equipment and operators, and increase production efficiency. The tool is to use 2 to 3 mm thick scrap iron welding, the middle open a rectangular groove, and then welded a horn funnel trough. When heating, place the square plate on a salt stove (be careful not to touch the electrode) and place the sample ring on both sides of the groove to preheat it. After a certain period of time, put the sample in circles
