Abstract
The purpose of this paper is to determine the amount of zinc-free slaking of HPb80-1.5 powder metallurgy during sintering. Experiments were conducted in a laboratory sintering machine under various conditions. The influence of processing parameters on zinc-free slaking was studied usin......
The method to solve the different wear amount of two wires during double wire rolling
Solution to Different Grinding Volumes of Double Steel Rolling
When producing certain steel structures through double steel rolling, it can sometimes happen that the rolling lines wear differently. This is usually due to incorrect setup, where tolerances between the two lines are too great, causi......
The role of slitting guides in slitting rolling
The Role of Slitting in the Rolling Process
The rolling process is a critical part of the production of metal parts. Rolling is essentially a form of pressure rolling that is used to resize and reshape metal parts by passing them through two or more sets of combined rolls. The engineering and met......
